summary As a result of the network-based nature of Internet and communications technologies, a new spatial form, which is defined as networked spaces by this research, is emerging. This paper provides a significant theoretical framework to unpack complex spatial relationships caused by the networked spaces. Such emerging design approach challenges the design thinking, design process and design knowledge of architecture, urban design, as well as media design.

title Interactive Storytelling and Its Role in the Design Process

summary Projects of ever increasing complexity and size have incited the need for new and robust design methodologies and tools in an effort to manage complexity, lower costs, ascertain quality and reduce risk. Technology convergence through the growing availability of networked computers, rapid progress in Computer Aided Design (CAD) and information management have encouraged the undertaking of even more complex designs that demand high degrees of interaction, collaboration and the efficient sharing and dissemination of information. It is suggested that interactive storytelling and interactive design (Rafi and Karboulonis, 2001) techniques that use non-linear information mapping systems can be deployed to assist users as they navigate information that is structured to address localized needs as they arise. The design process is a collaborative effort that encompasses diverse knowledge disciplines and demands the management and utilization of available resources to satisfy the needs of a single or set of goals. It is thought that building industry specialists should work close together in an organised manner to solve design problems as they emerge and find alternatives when designs fall short. The design process involves the processing of dynamic and complex information, that can be anything from the amount of soil required to level lands - to the needs of specific lightings systems in operation theatres. Other important factors that affect the design process are related to costs and deadlines. This paper will demonstrate some of our early findings in several experiments to establish nonlinear storytelling. It will conclude with a recommendation for a plausible design of such a system based on experimental work that is currently being conducted and is reaching its final stages. The paper will lay the foundations of a possible path to implementation based on the concept of multi-path animation that is appropriate for structuring the design process as used in the building industry.

title Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source Delft University of Technology
summary The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

In this paper, we describe the work in progress in developing ubiquitous/pervasive applications supporting digital design media presentation. The result of the experimental study in various spatial settings is reported. Finally, we present a model of interaction towards a human-centered reactive environment, and discuss some interaction and social issues that must be addressed in implementation.

summary In this paper, we examine the perception and understanding of spatial volumes within immersive, non-immersive virtual environments and physical models and their translation to a tangible representation in a series of design-representation experiments. Students experienced, assessed, and analysed spatial relationships of volumes and spaces and subsequently constructed models of these spaces. The goal of our study is to identify how designers perceive space in Virtual Environments (VE). We explore issues of quality, accuracy and understanding of rebuilding architectural experienced. By comparison of the same task within a screen-based or real 2D realm, we are able to draw some conclusions about aspects particular to immersive VE activity.

title Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) Tools.
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 451-476.
summary The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building’s Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.

title Presence and Flow in Virtual Environments: An Explorative Study
source University of Helsinki
summary Virtual environments (VEs) are thought to elicit a sense of presence to the user. The sense of presence is considered as a psychological experience of being in a world generated by the computer instead of using the computer from the outside. As a field of research the psychology of VE is quite new and not well explored. In this study the three components of the sense of presence are examined: spatial awareness, attention and the realness of the VE. The three components solution of presence is accused of following Cartesian tradition in separating perception from action. Interaction is considered an important part of the experience of presence. Some authors consider it as the only determinant of presence. The purpose of this study was to explore empirically this human experience. The idea was to integrate the presented presence components into a cognitive-emotional appraisal process from the environment. This type of an appraisal process in generating emotions dominates the field of modern psychological emotion theories. It has also been presented that similar appraisal process precedes optimal experience, i.e., flow. Flow has been used as a metrics to evaluate human computer interaction. However, there are only few studies in which both presence and flow has been measured. In this study the participants gained experiences while conducting a simple search task in a virtual CAVEtm. These experiences were measured with a questionnaire. Based on the results a three-dimensional framework was constructed. This framework integrated the experience of presence and interaction as well as an appraisal process from the environment based on one’s skills and challenges provided by the environment. In the appraisal process also personal relevance and evaluation of the interactivity of the VE are included. Framework also included two basic emotional dimensions arousal and control, which are considered important in producing the overall emotional experience. The framework was used to explain different endpoint experiences gained by the users. The results showed that the sense of presence is an integral part of the flow experience in VEs and in order to experience VE positively a user should experience both presence and flow in VE. Although, the framework needs more careful studying, it provides a fair depiction of the basic dynamics behind a subjective experience in VE.

title DAM: Digital Animation Museum
source University of Washington, Design Machine Group
summary The interaction of architecture and technology is, to many, simply a relationship between a building and the materials from which it is constructed. This thesis, however, explores the notion that architectural spaces and forms are influenced not only by construction technology, but also by everyday technology that we use to better our lives, and particularly focuses on the potential impact of wireless information technology on architecture. This thesis asserts that the implementation of information technology in architecture encourages greater interactivity between building and visitor and also increases flexibility in spatial programming. By incorporating wireless information technology as an essential design element of a museum, traditional notions of control points can be eliminated, and the building experience may be manipulated in a variety of ways to interact with and respond to visitor interests and preferences. In this way, both building and visitors are able to collaborate to produce a unique and individualized experience of the building space.

doi https://doi.org/10.52842/conf.caadria.2019.1.235
summary The paper presents the development of an agent-based approach to modelling the interaction of human emotion and behaviour with built spaces. The study addresses how human behaviour and social relation can be represented and modelled to interact with a virtual built environment composed in parametric architectural geometry. KOALA, a prototype of agent-based modelling of social spatial dynamics at the core of a parametric architectural design environment is proposed. In building KOALA's system architecture, we adapted the PECS (Physical, Emotional, Cognitive, Social) reference model of human behaviour (Schmidt 2002) and introduced the concept of Social Spatial Comfort as a measurement of three key factors influencing human spatial experiences. KOALA was evaluated by a comparative modelling of two contrasting Vietnamese dwellings known to us. As expected, KOALA returns very different temporal characteristics of spatial modifications of the two dwellings over a simulated timeframe of one year. We discuss the lessons learned and further research required.

title Using Social Interaction in Generative Design of Shared Virtual Spaces
source International Conference on Generative Art
summary The proposed paper outlines research findings in the field of generative design of visual virtual chat spaces. It discusses social interaction as a central determining factor in the generation of virtual spaces through and for chat communication on the World Wide Web. Social interaction in a chat room is based on communication using written text. The research and design results of this project involve the translation of chat statements into three-dimensional virtual objects according to - criteria derived from theories of virtual and social space, - the production of space through action and interaction of the users of the interface and - the translation of the components of written text (words and characters) into three-dimensional virtual forms. The generation of a dynamic, virtual, social structure is based on criteria deduced from systems of interaction within social space. The visual social structure, reflected in the shape and spatial relation of the three-dimensional objects, evolves as source for feedback processes and therefore as “re-generation” of social interaction. This paper documents the design, implementation and evaluation of the described system. It represents an outset and a first manifestation of a new project in cultural-differentiated user-interaction-centred generative approaches in interface design of chat room applications.

title Conception of Urban Space – Simulators Supporting Planning Work
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 87-90
summary Experimenting with “space”, joint exploring solution possibilities with all those concerned and the anticipation of the future involving as little risks as possible are important functions of space-related simulation contributing to increasing of knowledge, decision-finding and communication throughout the planning process. Questions as to conception of urban space, the modeling of urban volume and urban design, the improvement of spatial match (“fit”) and workability regarding utilization (”fitness for use”) call for suited simulators supporting planning work. All planning phases of urban-spatial planning processes are to benefit thereby: understanding is promoted, spatial characteristics developed, preservation- and renewal priorities are deduced, variants are conceived, spatial impact analysis of spatial ideas and graphic communication are to act as basis fordecision-finding. The present contribution also discusses the application possibilities of the “CAVE” (space with threedimensional image projections) as planning tool. The following questions are to be covered: qualitative and quantitative aspects of modeling of urban space, planning benefits arising from differing “levels of details” (LOD’s), “navigation in” and “interaction with urban spaces”, testing in line with requirements and examples of planning practice as well as current research- and development needs.

summary This paper discusses some preliminary ideas concerning new design environment or environment of designing. Main thesis of this paper is that process of creation and perception of architecture proceed between Real and Virtual. Architecture is created by analog and/or digital media. A the result we have the multitude and diversity of spaces and tools. Defining these terms is important for understanding a new process of design and a new space of designing. It gives us possibilities to create the new design environment, in which creation of architectural form may be considered as an integrated process connecting the analog, the digital, the real and the virtual. Architectural space, as we know it from physical environments, is supplemented by a virtual space. Physical, architectural and virtual spaces share very similar features in simulation. In virtual models, the boundary between the representation of physical sites and imaginary, virtual sites is vanishing rapidly, resulting in a new reality.

summary The use of computers in the design of the built environment has reached a watershed. From peripheral devices in the design process, they have in recent years come to take centre stage. An illustration is immediately at hand. Just as the entries to the competition for the Chicago Tribune Tower in 1922 defined the state-of-the-art at the beginning of the twentieth century, we have a similar marker at the end of the century, the competition in 2002 to replace the World Trade Centre towers in Lower Manhattan offered us a range of architectural solutions that exemplified the state-of-the-art eighty years later, setting forth not only architectural statements but also illustrating clearly the importance of computers in the design of the built environment. In these entries of 2002, we can see that computers have not only become essential to the communication of design but in the investigation and generation of structure, form and composition. The papers in this book are the current state-of-the-art in computer-aided design as it stands in 2003. It is the tenth in a series sponsored by the CAAD Futures Foundation, compiled from papers presented at the biennial CAAD Futures Conferences. As a series, the publications have charted the steady progress in developing the theoretical and practical foundations for applications in design practice. This volume continues in that tradition; thus, this book is entitled Digital Design: Research and Practice. The papers are grouped into three major categories, reflecting thrusts of research and practice, namely: Data and information: its organisation, handling and access, including agents; Virtual worlds: their creation, application and interfaces; and Analysis and creation of form and fabric. The editors received 121 abstracts after the initial call for contributions. From these, 61 abstracts were selected for development into complete papers for further review. From these submissions, 39 papers were chosen for inclusion in this publication. These papers show that the field has evolved from theoretical and development concerns to questions of practice in the decade during which this conference has showcased leading work. Questions of theoretical nature remain as the boundaries of our field expand. As design projects have grasped the potentials of computer-aided design, so have they challenged the capabilities of the tools. Papers here address questions in geometric representation and manipulation (Chiu and Chiu; Kocaturk, Veltkamp and Tuncer), topics that may have been considered to be solved. As design practice becomes increasingly knowledge based, better ways of managing, manipulating and accessing the complex wealth of design information becomes more pressing, demanding continuing research in issues such as modelling (Yang; Wang; Zreik et al), data retrieval and querying (Hwang and Choi; Stouffs and Cumming; Zreik, Stouffs, Tuncer, Ozsariyildiz and Beheshti), new modes of perceiving data (Segers; Tan). Tools are needed to manage, mine and create information for creative work, such as agents (Liew and Gero; Smith; Caneparo and Robiglio; Ding et al) or to support design processes (Smith; Chase). Systems for the support and development of designs continue (Gero; Achten and Jessurun). As progress is made on some fronts, such as user interfaces, attention is again turned to previously research areas such as lighting (Jung, Gross and Do; Ng et al; Wittkopf; Chevier; Glaser, Do and Tai) or services (Garcia; Chen and Lin). In recent years the growth of connectivity has led to a rapid growth in collaborative experience and understanding of the opportunities and issues continues to mature (Jabi; Dave; Zamenopoulos and Alexiou). Increasing interest is given to implications in practice and education (Dave; Oxman; Caneparo, Grassi and Giretti). Topics new to this conference are in the area of design to production or manufacture (Fischer, Burry and Frazer; Shih). Three additional invited papers (Rekimoto; Liu; Kalay) provide clear indication that there is still room to develop new spatial concepts and computer augmented environments for design. In conclusion, we note that these papers represent a good record of the current state of the evolving research in the field of digital design.

title Towards a multi-agent model for visualizing simulated user behavior to support the assessment of design performance
source Automation in Construction 11 (2) (2002) pp. 135-145
summary We introduce the outline of a multi-agent model that can be used for visualizing simulated user behavior to support the assessment of design performance. We will consider various performance indicators of building environments, which are related to user reaction to design decisions. This system may serve as a media tool in the design process for a better understanding of what the design will look like, especially for those cases where design or planning decisions will affect the behavior of individuals. The system is based on cellular automata and multi-agent simulation technology. The system simulates how agents move around in a particular 3D (or 2D) environment, in which space is represented as a lattice of cells. Agents represent objects or people with their own behavior, moving over the network. Each agent will be located in a simulated space, based on the cellular automata grid. Each iteration of the simulation is based on a parallel update of the agents conforming local rules. Agents positioned within an environment will need sensors to perceive their local neighborhood and some means with which to affect the environment. In this way, autonomous individuals and the interaction between them can be simulated by the system. As a result, designers can use the system to assess the likely consequences of their design decisions on user behavior. We think that the system provides a potentially valuable tool to support design and decision-making processes, related to user behavior in architecture and urban planning.

title The Side Effect of a Generative Experiment
source International Conference on Generative Art
summary This paper discusses the issue expressed in the call for the Generative Art 2002 conference that says: "GA is identifiable as one of the most advanced approaches in creative and design world." In this paper the value of Generative Art for the art, science and design worlds is described in the reference to a generative experiment. The experiment has been conducted in industrial environment with the aim of defining possibilities for natural interaction of humans with machines. In specific, the experiment examined an option for visual adaptation in accordance to user feedback. In the context of the experiment's outcome the issue of recognizability of Generative Art values is discussed. Generative Art can be identified but is not widely recognized as "one of the most advanced approaches in creative and design world". What makes it difficult for designers to switch to generative thinking and accept immediately Generative Art as the possible way of advancing traditional design methods? And what makes it promising to keep searching for ways of application of Generative Art in contemporary design? Some possible answers, proposed in this paper, aim at contributing to the discussion about the changing role of artists and designers in the contemporary society.

title A Complex Systems Perspective on How Agents Can Support Collaborative Design
source Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 95-111
summary Almost all complex artifacts nowadays, including physical artifacts such as airplanes, as well as informational artifacts such as software, organizational designs, plans and schedules, are created via the interaction of many, sometimes thousands of participants, working on different elements of the design. This collaborative design process is typically expensive and time-consuming because strong interdependencies between design decisions make it difficult to converge on a single design that satisfies these dependencies and is acceptable to all participants. Complex systems research concerning the generic dynamics of distributed networks has much to offer to the understanding of this process. This paper describes some insights derived from this novel perspective.

title Flow Structure Environment Simulation - A Comparative Analysis of Wind Flow Phenomena and Building Structure Interaction
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 564-568
doi https://doi.org/10.52842/conf.ecaade.2002.564
summary This paper documents the progress of research to investigate the integration of computational modeling techniques into wind mitigation analysis and design for building structures located in high wind prone areas. Some of the basic mechanics and theoretical concepts of fluid flow and wind pressure as well as their translation into design criteria for structural analysis and design are reviewed, followed by a discussion of a detailed Computational Fluid Dynamics (CFD) application case study for a simulated “3-second gust” wind flow over a low rectangular building located in a coastal region. The case study project models the wind flow behavior and pressure distribution over the building structure when situated in three varying conditions within a single terrain exposure category. The simulations include three-dimensional modeling of the building type constructed (1) on-grade in a flat coastal area, (2) above grade with the building elevated on structural columns, and (3) on-grade downwind of an escarpment. The techniques and parameters for development of the simulations are discussed and some preliminary interpretations of the results are evaluated by comparing their predictions to existing experimental and analytical data.

title Hybrid Digital Media Architectural Visualisation Delivery - Murcutt, Lewin & Lark's The Arthur and Yvonne Boyd Education Centre on Digital Flatland
source International Journal of Architectural Computing vol. 3 - no. 4, 487-502
summary This paper shares ongoing research explorations into visualising and representing architecture through the limited real-estate spaces of computer screens. It proposes greater access, 'interactivity' and clarity in digital representations for the study, analysis and/or digital record of existing architecture by drawing on concepts and strategies - within and outside the discipline - to arrive at hybrid visualisation techniques. To illustrate some of these techniques, the paper outlines several issues in the production of hybrid media representations of the Arthur and Yvonne Boyd Education Centre. This award-winning building was designed by the 2002 Pritzker Prize-winner, Glenn Murcutt in association with Wendy Lewin and Reg Lark. It is recognised as a landmark in Australian architecture and a worthy subject of our representation experiments.
