title	IMPROVING NEURAL NETWORK MODELS OF PHYSICAL SYSTEMS THROUGH DIMENSIONAL ANALYSIS
source	Journal of Applied Soft Computing 2(4): 283-296.
summary	The paper presents a technique for generating concise neural network models of physical systems. The neural network models are generated through a two-stage process. The first stage uses information embedded in the dimensions or units in which the data is represented. Dimensional analysis techniques are used initially to make this information explicit, and a limited search in the neural network architecture space is then conducted to determine dimensionless representations of variables/parameters that perform well for a given model complexity. The second stage uses information available in the numerical values of the data to search for high-level dimensionless variables/parameters, generated from simple combinations of dimensionless quantities generated in the first stage and which result in concise neural network models with improved performance characteristics. The search for these high-level dimensionless variables/parameters is conducted in an enhanced representation space using functional link networks with flat or near flat architectures. The use and effectiveness of the technique is demonstrated for three applications. The first is the design and analysis of reinforced concrete beams, which is representative of the class of problems associated with the design and analysis of composites. The second is the classical elastica problem, for predicting non-linear post-buckled behaviour of columns and the third, the analysis of a bent bar under a specified combination of loads.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	The Dynamics of Physical Ambiences
doi	https://doi.org/10.52842/conf.acadia.2007.174
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 174-181
summary	This research proposes to support the reading of physical ambiences by the development of a representational technique which compiles, in a numerical interface, two types of data: sensory and filmic. These data are recorded through the use of a portable array equipped with sensors (Potvin 1997, 2002, 2004) as well as the acquisition of Video information of the moving environment. The compilation of information is carried out through a multi-media approach, by means of a program converting the environmental data into dynamic diagrams, as well as the creation of an interactive interface allowing a possible diffusion on the Web. This technique, named APMAP/Video, makes it possible to read out simultaneously spatial and environmental diversity. It is demonstrated through surveys taken at various seasons and time of the day at the new Caisse de dépôt et de placement headquarters in Montreal which is also the corpus for a SSHRC (Social Sciences and Humanities Research Council) research grant on Environmental Adaptability in Architecture (Potvin et al. 2003-2007). This case study shows that the technique can prove of great relevance for POEs (Post Occupancy Evaluation) as well as for assistance in a new design project.

title	XML Technologies and Geodata
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	Photogrammetry and Remote Sensing are very important methods for acquisition of geodata. During the previous decade, severalrevolutionary changes occurred in this area. Until the appearance of automated image analysis tools, it was necessary to measureselected points in the images given. At that time, it was much faster and even cheaper to get images of real world objects compared tothe time and money consuming process of manual analyses. So one tried to minimize this effort by measuring only characteristicpoints such as edges, break-lines, peaks and valleys and, for sure, a grid with a given grid step which was selected to meet the efforts.Lots of information in the images was neglected.Digital point matching algorithms and airborne laser scanning provide many new possibilities. The only restriction on spatialresolution is the one of the used sensors. Given a more precise image sensor, the matching algorithm will be able to match moresurface points; given a higher frequency laser scanner, more points can be measured of the same area. And those sensors get moreand more precise every day. Besides, those techniques allow for fast repetition which is necessary to create time series as a basis for4D modeling! However, this fact is accompanied by several problems concerning the capability of available computers. Some years ago, as the first ideas of 3D city models arose, it was very difficult to acquire the necessary data. Today the new sensors and methods have thenecessary capability, but we are not able to handle the available datasets efficiently, because of shortcomings in the past. In a time ofworld wide data exchange through the internet and global datasets, it is necessary to have efficient methods and algorithms tomanage the available data. There is a need for international, vendor independent data exchange and management standards that haveto be accepted and supported by the industry. This article is going to present several methods of data encoding using standardized data formats based on eXtensible Markup Language (XML). After an introduction to this kind of data encoding, two derived applications for management, storage and presentation of geodata are described. As XML data is written in text format, the datasets have the ability to become rather long.Therefore some promising methods to reduce the amount of data are introduced afterwards. XML documents are mainly used fordata exchange between databases. Therefore the capabilities of commonly used database systems for storage of geodata are describedin the end and current implementation results of the Institute of Photogrammetry and Remote Sensing (I.P.F.) are presented.

title	Physical Simulation in a VR Tool for Urban Design
doi	https://doi.org/10.52842/conf.acadia.2003.395
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 395-401
summary	Physical influences on a city, such as noise, light, air flow, and solar energy quantities, can already be simulated on computers; however, these simulations are usually not embedded into the urban planning process. Regarding a broad field of these influences and their correlations will improve the quality of the design. The use of simulations in the sketching stage provides the possibility of reacting accordingly for the urban planner, which is essential for sustainable design. This paper describes the development of a virtual reality tool for the early urban design process, in which we realized a network connection between a software package calculating noise propagation in urban spaces and a virtual reality design environment. In this dynamic VR design tool, it is possible to experiment with simple geometric forms and objects (these objects can be added to constructions, removed, and transformed). Interactively, with each action of the planner, simulations are generated and visualized in the VR environment in real-time. The last part of the paper describes our concept, how this VR design tool should be integrated in the study of urban planning, and how we want the students to get a sense for the impact of their design on physical phenomena in an urban scale.

title	The Tangible Interface: Experiments as an Integral Part of a Research Strategy
source	International Journal of Architectural Computing vol. 1 - no. 2
summary	The Human-Computer interface is crucial to good design support tools. It has to be non-interruptive and non-distracting, yet allow the architect to interact with the computer software. The physical reality of the interface, such as the shape and manipulability of devices like the mouse, keyboard, joystick, or data-glove, has to be mapped on actions and commands in the software. Already the current user interfaces are felt to be inadequate for a good support of design, and the functionality of design tools is growing, requiring even more and new physical interface devices. In this paper, we present research on new tangible interfaces for architectural design support. In particular, we focus on the research methodological question how to investigate such devices.The research strategy is introduced and discussed, after which concrete implementations of this strategy are shown. Based on this work, we conclude that the combination of interface and the context of its use in terms of design method and user needs form crucial aspects for such research and cannot be considered separately.

title	Realism vs. Reality in Digital Reconstruction of Cities
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The digital reconstruction of existing cities using virtual reality techniques is being increasingly used. For consultants, municipalities and planning departments these models provide decision support through visual simulations (El Araby, 2001). For academia they provide a new tool for teaching students urban design and planning (Okeil, 2001). For authorities they provide a tool for promoting the city on the world wide web trying to attract more businesses and tourists to it. The built environment is very rich in detail. It does not only consist of open spaces surrounded by abstract buildings but it also includes many smaller objects such as street furniture, traffic signs, street lights, different types of vegetation and shop signs for example. All surfaces in the built environment have unique properties describing color, texture and opacity. The built environmentis dynamic and our perception is affected by factors such as pedestrian movement, traffic, environmental factors such as wind, noise and shadows. The built environment is also shaped by the accumulation of changes caused by many influences through time. All these factors make the reconstruction of the built environment a very complex task. This paper tries to answer the question: how realistic the reconstructed models of urban areas can be. It sees “Realism“ as a variable floating between three types of realties. The reality of the physical environment which we are trying to represent. The reality of the digital environment which will host the digitally reconstructed city. And the reality of the working environment which deals with the problem of limitation of resources needed to digitally reconstruct the city. A case study of building a 3D computer model of an urban area in the United Arab Emirates demonstrates that new time-saving techniques for data acquisition can enhance realism by meetingbudget limitations and time limitations.

title	An Agent Approach to Supporting Collaborative Design in 3D Virtual Worlds
doi	https://doi.org/10.52842/conf.ecaade.2003.047
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 47-52
summary	3D Virtual worlds facilitate a level of communication and collaboration not readily available in conventional CAD systems. The integration of virtual worlds and CAD systems using a common data model can make a significant impact on synchronous collaboration and real time multi-user multi-disciplinary modification of building data. By using agents, the integration of 3D virtual worlds and CAD systems can go beyond that of passive data transfer. With sensors and effectors, each agent can interact with its environment by responding to changes in the CAD system or 3D virtual world, which can take the form of an update to the geometry, or as a recommendation to change non geometric information or to propagate changes to other parts of the design. The reasoning process for each agent can vary from a reflexive behaviour in which the agent responds directly to the sensor data to a reflective behaviour in which the agents reasons about its goals and alternatives before making a change to the environment. We demonstrate this approach using ArchiCAD and Active Worlds as the CAD system and the virtual world platform. An EDM database is used as the central repository for storing the representation of the relevant data model. A multi-agent system is developed to connect the virtual world to this database to allow active data sharing. This agent approach can be extended to the integration of other applications and data models.

title	Starting From The Micro A Pedagogical Approach to Designing Responsive Architecture
doi	https://doi.org/10.52842/conf.caadria.2003.761

summary	The paper outlines a pedagogical approach whereby a number of technology-intensive skills can be quickly learned to a level of useful practicality through a series of discrete, yet cumulative explorations with the design goal of creating intelligently responsive architectural systems. The emerging area of responsive architecture serves as a practical means for inventing entirely new ways of developing spaces, and the designing and building environments that address dynamic, flexible and constantly changing needs. Responsive architecture is defined here as spaces and objects that can physically re-configure themselves to meet changing needs. The central issues explored are human and environmental interaction and behaviors, embedded computational infrastructures, kinetic and mechanical systems and physical control mechanisms. Being both multidisciplinary and technology-intensive in nature, architects need to be equipped with at least a base foundational knowledge in a number of domains in order to be able to develop the skills necessary to explore, conceive, and design such systems. The teaching methods were carried out with a group of undergraduate design students who had no previous experience in mechanical engineering, electronics, programming, or kinetic design with the goal of creating a responsive kinetic system that can demonstrate physical interactive behaviors on an applicable architectural scale. We found the approach to be extremely successful in terms of psychologically demystifying

title	Are European cities becoming similar?
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The paper discusses city specific development patterns to overcome todays transport problems. The results are based on recent andongoing research activities at TUW-IVV and ITS. At previous CORP-conferences, we presented the basics and the development of aplanning support tool to find optimal policy packages in urban transport and land use (Emberger, 1998), (Pfaffenbichler, Emberger, 2001). The core of this planning support tool is a dynamic land use and transport interaction model. This model, which we refer to as Sketch Planning Model (SPM), is embedded into an appraisal and optimisation framework. The SPM and this framework were developed in the recently finished European Union funded research project PROSPECTS1. Case studies with this planning supporttool were performed within PROSPECTS for the cities Edinburgh, Helsinki, Madrid, Oslo, Stockholm and Vienna. These cities are principally comparable in regards of their status (capitals and major business and education centres), but different in their size, population density, transport system etc. A set of policy instruments like public transport improvements, car traffic restrictions, and infrastructure provision was available to formulate strategies to reduce negative impacts of transport and to increase welfare. The overall objective was a sustainable development of the city. Although the instruments and the goals are similar in all investigatedcites, different solutions were adequate. The solutions vary in regard of spatial implementation, implementation time and level of implementation. The paper will highlight some reasons for the different development paths of the cities. As well the comparison of the do nothing scenario as the comparison of the most feasible policy strategies shows that European cities are different, need different solutions for their problems and will stay different in the future.

summary	Sixteen (makers) are a group of practicing architects, academics, designers and makers who assemble when key questions surrounding design, fabrication, use and adaptability in architecture emerge. Initially, the group was formed out of a motivation to engage as designers with the physical and tactile aspects of production without a dependency upon drawing. Now, in the post digital age, the age of digital fabrication, boundaries between drawing and making, between the designer and the maker, have dissolved. Consequently sixteen(makers) work is now engaged with questions of knowledge transfer, expertise, and innovation where modes of investigation are equally embedded within in the analogue and the digital world. This article relates to our latest ongoing work which is due for completion in 2005/06. The work has been developed as a specific response to the award of an architectural residency by the Art and Architecture Partnership at Kielder Park, Northumbria, England. From the outset, it has not been a requirement of the residency that an outcome is identified early on. In fact, as I write, the outcome remains open. Presented with an extraordinary site and coinciding with a time of rapid change the work has begun by exploring a design process that is adaptable, indeterminate, and informed by site conditions. In October 2003, sixteen(makers) were awarded an architecture residency by The Art and Architecture Programme at Kielder (AAPK) of Northumbria, UK. This organization is well known for commissioning works such as the ‘Belvedere’ by Softroom and the ‘Skyspace’ by James Turrell. Coordinated by Peter Sharp, AAPK consists of a number of large public bodies, including The Forestry Commission, Northumbrian Water and Tyndale District Council. Together they manage a land area of 62,000 ha’s centred on the UK’s largest reservoir and surrounded on all sides by one of Europe’s largest managed forests.

summary	CAD tools are increasing their expressive and geometric power to enable a design process in which the computer model can be used throughout the whole design process for realizing the design. Such a process, in which other media such as physical scale models or drawings are no longer required by necessity to facilitate the design process, can be considered a digital design process. Rather than proposing that such a process is ideal – drawings and scale models should not be discarded – we feel that when taken as a starting point, the digital design process raises a number of new challenges to architectural design that deserve attention. These challenges concern the basic activities in design: exploration of the problem space, creating preliminary solutions, understanding consequences of design decisions, and so forth. In this paper we take the concrete design case of a graduation project that was developed from the start solely in CAD. We identify a number of key issues in that process such as continuous modeling, the model as design, continuous pliability, localized focus, and postponed decision. These issues not only have a technical, CAD-related aspect, but also are connected to architectural design. Most of these aspects are subject of contemporary debate in architectural design. On this basis, we can indicate where CAD is making a potential difference in architectural design.

title	Four Degrees Of Freedom
doi	https://doi.org/10.52842/conf.acadia.2003.x.s7a

summary	Letting go is hard to do. Remember back to when, after months of trying, you let go of the handlebars of your bicycle and sailed down the street, effortless and assured. It was a freedom born of mastery, balance and technique. You had let go, but were in control. Technique extends to other devices as well and we are here to discuss architectural computation. Here too, as we will see, mastery is shown by letting go. These papers explore new degrees of freedom in design computation. Each is on a separate aspect of architecture, whether it be aesthetics, process, or structure. Two papers inquire into the entities of design and the processes by which they are manifested. They pose important questions. If we can affect the course of design going forward, are we free to change its past? By defining the characteristics of objects at the outset, are we through automation free to choose from a refined spectrum of outcomes? From the evidence of these papers, the answer to both questions is yes. Through the agency of parametric design we can affect the future and past of architectural processes and their products. Rather than being locked into rigid, linear decisions we are temporally free to choose, tweak and modify. Choice and chance play an important role in aesthetics as well. This has become emblematic of design trends as we have seen in recent years. One of our papers addresses the indeterminacy of particle systems in the design of a monument to the victims of 9/11. By letting go of the handlebars of the computer, the author has been freed to new, poetic forms and processes. Another paper opens urban design to its client community by use of a sophisticated web site. In the tradition of populist innovators like Charles Moore and Lucien Kroll, the authors have extended the design process beyond the office walls to the city itself. The designers, by loosening their grip on the project have made the effort democratic and participatory. Intriguingly, at the end of the paper, they note that this use of cyberspace opens the door to a non-physical architecture. Could architecture, then, let go its materialist biases as well? We hope to engage this and other questions shortly.We are pleased then, to share with you these insights and projects. Wassim and I hope that these presentations will be as liberating for you as they were for us.

title	A Critical Evaluation of Early Stages Software in its Capacity of Coping with Contextual Issues
source	LOCAL VALUES in a NETWORKED DESIGN WORLD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Stellingwerff, Martijn and Verbeke, Johan (Eds.), (2004) DUP Science - Delft University Press, ISBN 90-407-2507-1.
summary	In this paper we analyse critically early design stages software in its capacity of coping with contextual data at large (i.e. representing cultural, aesthetical context, etc.). We identified 5 categories of early stages software: geometry based graphic editors, evaluation architectural software, generative and shape-grammar based systems, evolutionary systems and other systems. Calling the object under creation during of the early stages a CAD conceptual model, we will investigate to what extend this software allows the architect to experience and represent the context in which a design is situated. Especially we will focus on its capacity to allow interaction, playful interaction on our way to the design. Designers, and particularly architects, interact with the local context similarly to interacting in a game: the context influences the users’ decisions, surprises them and causes permanent changes to their ways of thinking. On the other hand, architects permanently shape and reshape the context, and reduce the context to a protean point of reference. Such behaviour characterises creative thinking that is crucial for the early stage of design. The investigation led us to the conclusions that the effective interactivity with the context needs simple rules, a plain interface and data reduced as simple as possible, especially when interaction with the context is performed during the early stages of a design process. The findings can be used in organising computer environments for early-stage design.

title	The Geographical Alpine Information System “Galpis” in the Raumalp Project. Outlay and Output
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	RAUMALP, an interdisciplinary research project of the Austrian Academy of Sciences, shall examine problem areas of spatial development on community level in the Austrian alpine region. The aim is the investigation of scientific basics for political decision finding, especially for the regional-specific realisation of the Alpine Convention. All ascertained information shall be included in “GALPIS”, a comprehensive Alpine Space Information System. GALPIS based on ESRI ArcGIS and MS Access software works with data from different sources, like ISIS, the electronic data base of Statistic Austria, and original data and maps gathered and elaborated by the working groups of RAUMALP. This also includes ecological raster data. Dealing with administrative units, „real“ space and raster space, RAUMALP will integrate the different space levels mostly to administrative spatial units representing the existing 1145 communities of the RAUMALP study area. This will be realised by overlay of grids, types of land use and communitypolygons. Major task of GALPIS is a conversion of former communal data (p. e. 1451 communities in 1951) that should represent the recent administrative boundaries. By this way it is possible to make thematic and time-integrative analyses of community data. GIS modelling of the six case studies is more complex. The conceptual model has to integrate several vector and raster layers such as land plots (“Digitale Katastralmappe”), types of land use (“Land Use and Land Cover Austria” by M. Seger) and biodiversity. P. e., the working group settlement is using a logical data model based on the entity “building” with the attributes “construction”,“function”, etc.

title	Metodología Interdisciplinaria para Diseñar Nuevas Arquitecturas de Representación de Datos (Interdisciplinaria Methodologies for the Design of a New Architectures of Data Representation)
source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	Data representation architecture can be defined as the organizational, functional, experiential, formal, and media-technological order defining the interaction between data, representation, and user. This paper presents an interdisciplinary methodology to develop such architectures in order to significantly improve real time decision making in complex data environments. We have reported in some aspects of this work elsewhere. In this occasion, we will describe our working methodology based on complete interdisciplinarity, the design process and evaluation protocols. We will show work done for Finance and Network Monitoring. Our long-term goal is to design a new generation of data representation architectures that is applicable to diverse fields.

summary	This paper describes a practice-led research project that investigates the application of digital modelling and communication technologies in urban and architectural design. The project is being carried out by our team with the collaboration of the architecture and planning departments at local borough council and local community participation. The main methodology for the project revolves around the evolution of an interactive three-dimensional digital urban model, which incorporates a variety of visual, graphic and numeric data. This digital model is utilised within a web site to help facilitate a participatory approach to the physical and social regeneration of an inner urban zone, in terms of both the built environment and the attempted creation of a virtual community.

title	Using Actuated Tensegrity Structures to Produce a Responsive Architecture
doi	https://doi.org/10.52842/conf.acadia.2003.085
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 85-93
summary	The major theoretical roots of responsive architecture lie within the work of Nicholas Negroponte, and its most inspiring realization, to date, is found in the work of dECOi Architects. The work of NOX, and Diller & Scofidio provide two other built examples of responsive architectures. Each of these works is impressive within its own right. However, all of them have their shortcomings, suggesting that several possibilities for alternative visions still exist. While Negroponte’s work identifies the characteristics of a responsive architecture, it does not propose a model that is suitable for implementation. On the other hand, the work of dECOi architects does not address the technical needs of a building envelope designed for real world conditions of weather and structural load. Diller & Scofidio’s work, also does not have a functional envelope, and NOX’s work lacks physical responsiveness, favoring a palate of virtual responses instead.This paper, after examining the four specific precedents of Negroponte, dECOi, Diller & Scofidio, and NOX, will examine how a fifth precedent—that of Buckminster Fuller’s model of tensegrity structures—may be applied. The paper will propose that by actuating a tensegrity structure a responsive architectural envelope that addresses real world weather and structural loading conditions becomes feasible.

title	How to Plant a Subway System

summary	We speculate on a possible CAAD future that deploys and extends paradigms of natural growth and cellular development to an extent that would allow the planting and growth of man-made structures. This approach is based on the translation and expression of digital data structures into artificial physical form and the building of structures by decentral means. In such a scenario, generative and evolutionary architecture could seamlessly blend into building construction. As a discussion of as yet unavailable future technologies and methodologies the proposed remains at a “sketchy” level and must largely limit itself to preliminary and speculative considerations. In order to restrain the scope of this paper to the area of building design and construction, we focus on subway development and discuss possible cellular approaches to this particular field emphasizing aspects of functional aesthetics. We encourage the reader to take this example as a point of departure only, to generalise our explanations and to apply them to other building types. We support our discussion with findings made in software simulations of humandesigned cellular growth processes.
