Describing the residential valorisation of urban space at the street level. The French Riviera as example

There is a growing concern regarding the use of relatively coarse units for the aggregation of various spatial information. Researchers thus suggest that the street segment might be better suited than areal units for carrying out such a task. Furthermore, the street segment has recently become one of the most prominent spatial units, for example, to study street network centrality, retail density, and urban form. In this paper, we thus propose to use the street segment as unit of analysis for calculating the residential valorisation of urban space. To be more specific, we define a protocol that characterises street segments through a measure of central tendency and one of dispersion of prices. Moreover, through Bayesian clustering, it classifies street segments according to the most probable combination house type-valuation to provide a picture of local submarkets. We apply this methodology to the housing transactions exchanged in the French Riviera, in the period 2008–2017, and observe that outputs seem to align with local specificities of the housing market of that region. We suggest that the proposed protocol can be useful as an explorative tool to question and interpret the housing market, in any metropolitan region, at a fine level of spatial granularity

Identifying Trends in Masterplanning: A Typological Classification System

This document is the Accepted Manuscript version of the following article: Robert Adam, and Claire Jamieson, ‘Identifying trends in masterplanning: A typological classification system’, URBAN DESIGN International, Vol. 19 (4): 274-290, December 2014. The final publication is available at Springer via https://doi.org/10.1057/udi.2013.24.This article reports research carried out to develop a new typological method for the analysis of masterplans. This quantitative method of analysis can be used to produce comparative data that will help in the comparison of urban design typologies and their development over time. This article sets out the research to date, describing how the initial aims have developed from simple analysis to the creation of an analytical tool with wide applications. Comprising a detailed taxonomy of urban design features gathered from a wide database of recent and emerging masterplans, the system provides opportunities for further study such as trends, qualitative comparison against quantitative measurement, and comparison of aims and outcomes. This article will describe the methodology and process of research, while elaborating on the potential of the tool.Peer reviewedFinal Accepted Versio

On the origin of spaces: morphometric foundations of urban form evolution

The modern discipline of urban morphology gives us a ground for the comparative analysis of cities, which increasingly includes specific quantitative elements. In this paper, we make a further step forward towards the definition of a general method for the classification of urban form. We draw from morphometrics and taxonomy in life sciences to propose such method, which we name ‘urban morphometrics’. We then test it on a unit of the urban landscape named ‘Sanctuary Area’ (SA), explored in 45 cities whose origins span four historic time periods: Historic (medieval), Industrial (19th century), New Towns (post-WWII, high-rise) and Sprawl (post-WWII, low-rise). We describe each SA through 207 physical dimensions and then use these to discover features that discriminate them among the four temporal groups. Nine dimensions emerge as sufficient to correctly classify 90% of the urban settings by their historic origins. These nine attributes largely identify an area's ‘visible identity’ as reflected by three characteristics: (1) block perimeterness, or the way buildings define the street-edge; (2) building coverage, or the way buildings cover the land and (3) regular plot coverage, or the extent to which blocks are made of plots that have main access from a street. Hierarchical cluster analysis utilising only the nine key variables nearly perfectly clusters each SA according to its historic origin; moreover, the resulting dendrogram shows, just after WWII, the first ‘bifurcation’ of urban history, with the emergence of the modern city as a new ‘species’ of urban form. With ‘urban morphometrics’ we hope to extend urban morphological research and contribute to understanding the way cities evolve

Towards analytical typologies of plot systems: quantitative profile of five European cities

The importance of the plot (also referred to as ‘property’) as one of the fundamental elements of urban form is well recognized within the field of urban morphology. Despite the fact that it is often described as the basic element in the pattern of land divisions, which are essential as organizational frameworks for urban form, studies offering comprehensive descriptions and classifications of plot systems are quite scant. The aim of the paper is to introduce a classification of plot systems into typologies based on five European cities, in order to distinguish particular spatial differences and similarities in terms of their plot structure. The proposed typologies are developed using unsupervised k-means cluster analysis based on numeric attributes derived from central theories in urban morphology. The introduced typologies are essentially configurational, allowing collective systematic properties of plot systems to be captured. Numeric attributes include plot differentiation (or plot size), plot frontage and compactness ratio, corresponding to essential qualities of plot systems such as the capacity to carry differences in space, the ability to operate as interface between street and building and providing a framework for evolution of built form over time. All three attributes are translated into configurational measures in order to capture the context of the plot system, rather than the parameters of individual plots. The combination of these deductively defined variables with algorithmically defined classification methods results in seven plot types that can be used to scale up traditional urban morphological analysis to whole city regions and conduct substantial comparison of patterns within, but also between these regions. Further, it also makes it possible to describe commonly recognized plot patterns and discover new ones

Preserving the cultural identity of Chinese cities in urban design through a typomorphological approach

This paper analyses the historical process of transformation of the urban blocks, plots and building fabrics in Suzhou, China from the tenth century to the present day using a typomorphological approach, and offers some design suggestions for urban designers and policy-makers based on the examination of the local context. The study aims to propose the western typormorphological concept in Chinese urban design, to maintain local cultural identity in an era of rapid globalisation. The study reveals that typormorphology is an effective tool to solve the current problems in urban developments, and should be adopted in both the urban analysis and urban design of Chinese cities

The Importance of Urban Form as an Object of Study

The importance of urban morphology is argued from three perspectives—philosophical, cultural and practical. Urban morphology makes sense of the world around us and this chapter will demonstrate the importance of ‘ways of seeing’, arguing for a philosophical approach that integrates physical, social and cultural dimensions of cities. Culturally, understanding urban morphology is a prerequisite to an awareness of urban aesthetics and the layers of meaning attached to townscapes. Through such appreciation, its study adds to the quality of life. Practically, the study of urban morphology performs a vital educational function. Through the detailed study of urban form, we learn both what not to do and how to do things better, a vital objective in achieving successful and holistic urban management. Urban morphology provides an appreciation and unique training for integrating closely related fields of practical application such as urban design, planning, architecture and conservation

Troubled proximities: asylums and cemeteries in nineteenth-century England

Asylums and cemeteries in nineteenth-century England were kindred spirits in the anxiety and exclusionary impulses that they engendered, leading them to be similarly exiled from nineteenth-century urban areas. They were uneasy ‘neighbours’, however, with contemporary authorities condemning the proximity of cemeteries to asylums on medical and moral grounds. The appearance at many asylums after mid-century of a burial-ground for deceased residents, usually located on an asylum’s own estate, was often criticized on grounds similar to those raised with respect to neighbouring parochial burial-grounds. Other objections arose to the ‘exclusivity’ of asylum-based burials, with off-site burial arrangements clearly being favoured. One consequence was that on-site asylum cemeteries ended up being treated as unwelcome occupants of asylum estates, hidden away as an embarrassment, creating a legacy of anonymity still generating concerns in the present
