Abstract

Space syntax has made major contributions to the methodology of description of the cognitive level of urban space. As such it has the potential to inform other disciplines studying cities, such as urban sociology and urban geography but not least urban economics and economic geography. As a background to a methodological exchange, in this session we will briefly give the background to the traditions of description and modelling of urban space in the two disciplines.

Our particular focus is the spatial analysis of urban land, from the point of view of theory and not least practice. Spatial urban form constitutes a spatial capital that enhances other forms or urban capital, such as social, economic and ecological capital. It contributes substantially to land values, which as real estate value constitutes at least two thirds of current global wealth. It therefore seems essential to better understand and measure spatial capital. Space syntax analysis seems to be an unusually useful theory and method to capture the evasive entity of land value.

Given its exceptional part of global wealth, it is surprising that the methodologies for describing urban land as a means to better follow its value flows are so little developed. The core distinction between “land value” and “land improvements”, together making up “real estate” values, is critical. Land value is primarily created on public land through accessibility and definition of location, including by the configuration of street networks. Land improvements on the other hand, are created by developments of private land, primarily through new buildings. Hence, in morphological terms, the first concerns location as defined by centrality and the second density, both possible to analyze in great detail using space syntax methodology.

As a large part of “real estate values” are created though public investment on public land and not only investments by landowners on their own land through buildings, the latter is only the beginning of the complex landscape of externalities that cities constitute. Fundamentally, despite the complex flow of value between both public and private pieces of land, and between different private pieces of land, it is not unproblematic to treat land as discrete commodities. To a major extent, the value of each piece is created by what happens outside the individual piece.

Altogether, space syntax methodology is able to play an essential role in the closer analysis of these flows. First, there is a need to improve description of location in the valuation of land, both in itself and as part of real estate value. This has implications for several economic issues, including land tax. Second, it plays an essential role in deciding power relations in urban development, where a better description of location may create a sounder foundation for urban development negotiations. Third, it has implications for a third category of actors here, namely the users or customers of both public and private land, who in the end are the ones to pay for the use of land, by tax or by rent.

The session will be divided into two presentations as a background for discussion.

Lars Marcus is an architect and professor in Urban Design at Chalmers University of Technology where he together with Meta Berghauser Pont initiated the research group Spatial Morphology Group (SMoG). He earlier held the same position at the Royal Institute of Technology (KTH), where he initiated a similar group, Spatial Analysis and Design (SAD).

His research concerns how spatial form, as defined by architecture and urban design, supports, structures and sets limits to people’s everyday life and in extension how spatial form conditions vital social, economic and ecological urban processes, such as social integration, local markets and urban ecosystems. More recently he has addressed the issue of location and land values.

Key contribution have been the addition of other variables than centrality to typical space syntax analysis, such as density and differentiation (especially the theory of spatial capacity in relation to the latter); the support of such analysis through what has come to be called place syntax analysis, which integrates any geographic data into space syntax analysis; original steps to include ecosystems in such analysis through distance measures based in the cognition of other species than humans.

He is currently summarizing a lot of this research in a book called Spatial Capital – Measures and Meanings to be published at MIT Press early 2025.

Lars is also founder (2000) and partner (2005-2022) of the consultancy firm Spacescape, performing spatial analysis, design support and policy development in architectural and urban projects for architects, municipalities and real estate companies.

The spatial syntax of health: on the dynamic interplay between people, environment, and policy

Rosie McEachan

Born in Bradford

Abstract

Nikolas Rose and Des Fitzgerald recently wrote of the “dynamic interplay in which human bodies and human environments constrain each other, mark each other, intermingle in an awkward, shuffling embrace” (The Urban Brain, 2022). Their call to consider the organic and biological contingencies of place when undertaking health research is central to this keynote session jointly led by Professor Rosie McEachan, Director of Born in Bradford and applied health academic, and Professor Laura Vaughan, Director of the Space Syntax Lab and academic investigating urban form and society.

It will open with a talk from Laura Vaughan, who will touch upon two key aspects of urbanism in space syntax theory: first, that how where you live shapes your social, economic and health outcomes; and second, how the position of that location within the wider city is of equal importance: being spatially segregated from life beyond your neighbourhood can have just as profound an effect on life outcomes as the circumstances of the street where you live. She will elaborate on the history of mapping health from the early 19th century till today, covering both communicable and non-communicable disease, to show how a specifically socio-spatial approach can enrich research into patterns of disease. Bringing a space syntax lens to health studies, by taking account of the configuration of the built environment, we can start to find ways to make significant contributions to make environments healthier. Mapping of non-communicable disease, for example, obesity, mental ill health and other chronic disease also reveals the important role of the environment – which can either enable healthy lifestyles (for example, providing safe place to socialise and be active) – or hinder health (for example, obesogenic environments).

The talk from Rosie McEachan will highlight the revolutionary approach of the Born in Bradford cohort study, which follows the lives of over 60,000 residents living in a multi-cultural, deprived city in the North of England to find out why some families stay healthy and why others fall ill. Using a City Collaboratory approach, the project works with the local government authority, health, education and voluntary sector providers across Bradford district to develop, implement and evaluate programmes to improve population health.  With a focus on environmental determinants of health she will describe how the evidence collected from their ‘people-powered’ research programme led to policy change in the city.

The two speakers will then jointly outline the benefits and challenges of working across disciplines. Starting with the strengths and mutual learning to be found in interdisciplinary research, the presentation will outline the critical differences, such as in concepts, in timing, as well as epistemological differences (and how these can be overcome). Issues of how each discipline meets the demands of producing evidence of what works, when research timescales (and researcher’s own approach to the practice) differs from the policy-maker’s requirement to address an urgent societal/political/economic challenge are one of the matters that will be discussed. Lastly, how academic researchers can make what they do useful, developing relationships with decision-makers for example, will close this part of the session. The final part of the session will be a Q&A discussion with the audience.

Architecture meets Sociology – re-imagining users from two disciplinary perspectives

Keynote 1

Learning from Sociology: Diversifying what we mean by space usage behaviours in space syntax

Prof Kerstin Sailer, The Bartlett School of Architecture, UCL

 Space syntax aims at explaining how spatial structures lead to a patterning of behaviours and social outcomes. Some of its major theoretical breakthroughs, for example the understanding that movement flows correspond to spatial configuration is based on aggregated patterns of use, collected by methods of observation. This picture of collective use has spawned a whole range of relevant and important research insights, however, can be critiqued for being agnostic towards social differences between users. It could be argued that the same spatial structures offer different opportunities for use depending on user characteristics.

In this keynote I will argue that as a community we have a lot to learn from sociology, where the principle of social stratification, i.e., the classification of people into groups (by socioeconomic status, class, race, gender, age, religion, sexuality and so on) as well as the resulting hierarchies and inequalities are foundational to the discipline and bring forth elaborate and detailed insights into human nature. I will present several examples from my past and ongoing research into space usage behaviours in buildings highlighting how we can study diverse usage patterns in different ways, leading to a more nuanced understanding of the role that layouts play for users.

Keynote 2

Sociologists learning from Architects: The somatic politics of the end-user

Dr Daryl Martin, The University of York

In this keynote, I will respond to Kerstin Sailer’s argument that space syntax engages with traditions of sociological thought, so as to better understand space usage behaviours. I will draw on insights from sociological thinking that can help us to complicate generic notions of the ‘end-user’ within architectural discourses, and in so doing reinvigorate aspirations for an architectural practice which remains open-minded to how future spaces may be touched, felt and inhabited in everyday ways by those who may use them.

Specifically, I will draw on examples from my previous research on the design of buildings for health, care, and wellbeing. I do so in order to illuminate how architecture can sometimes constitute a form of ‘body work’, as designers imagine the multiplicity of bodies that will use their buildings. At their best, architects can work with sociologically attuned understandings of users’ bodies in all their corporeal diversity and emotional complexity, in order to produce designs that are sensitive to understandings of architecture as a temporal, as well as a spatial, craft.

Title: 

Intelligibilities of urban forms

Abstract:

The measure of axial intelligibility formulated by Hillier et al. (1987) contributed to a better understanding of the impact of urban layout on wayfinding and navigation. Its transferability to the street segment representation has proved challenging, highlighting to some extent the different development logics and complexities arising from urban environments depending on whether they are planned, incremental, or informal. Building on this work and more recent research, this talk explores further the nature of exploration in relatively simple and complex environments that arise from their development process. It revisits and discusses the notion of ‘intelligibilities’ to reflect the diversity of experiences when navigating various urban environments.

Biography:

Alice Vialard (PhD) is a senior lecturer at the University of Sydney in the School of Architecture, Design and Planning. Her main research builds upon her thesis “A typology of block-face” (Georgia Tech, 2013) which sits at the intersection of the field of Space Syntax and Urban Morphology, using quantitative analysis. Her interest lies in the relationship between building and urban scales, and how the interface between the two is mediated and expressed in the frontage. Her recent work has been looking at the cognitive mechanisms that underlie the process of exploration and decision-making when navigating urban environments through drawing tasks. In partnership with a medical device company, she is currently working on a project that examines the motor aspect of decision-making during the navigation process for people with dementia, looking at the quantification of neuromotor impairments. Before joining the University of Sydney, Alice studied and taught in institutions in France, USA, UAE and UK, which brings a multicultural approach to her research.

Title:

Advancing space syntax knowledge through open workflows and open data

Summary:

Open science aspires to contribute with transparency, inclusivity, reproducibility and collaboration to research quality and the advancement of knowledge. The space syntax community has historically engaged in open-access publication, open training material and open-source software, with benefits to the wider dissemination and application of its theories and methods. I will be focusing on two additional aspects: open workflows in research design and methodology; and open (empirical) data with which to test hypotheses and validate spatial models. A successful adoption of such practices has the potential to stimulate new cycles of research and innovation within the space syntax community.

Title:

Epistemic Divagations on Space Syntax

Summary:

In the murky waters of architectural theory, where opinion and knowledge are often conflated, space syntax stands out for its uncommon scientific ethos. However, an uncommitted epistemological outlook of the theory is still missing. What is it that makes space syntax so different from other architectural theories? Which concepts lie at its core and which are its foundational beliefs? Are those beliefs justified? Are the central concepts testable? Does the theory make implicit or explicit predictions, which may be falsified? Can we devise convincing experiments, capable of confirming (or refuting) such predictions?

Questions like these may seem rhetorical, at least for seasoned space syntax practitioners. Still, they directly address the epistemological validity of the field and need to be posed, if only to assure the solidity of its conceptual footings and the rebuttal of its critics. In this talk I would like to start the sketch of an epistemology of space syntax theory. Without any intention of being conclusive, or even comprehensive, I will try to address the above questions in the hope of sparking such debate.
