  • The �Spacemate� diagram of Berghauser Pont and Haupt [2004 Spacemate: The Spatial Logic of Urban Density (Delft University Press, Delft); 2005 Nordisk Arkitekturforskning 4 55�68] relates together three geometrical properties of buildings: density expressed as a floor space index (FSI), ground coverage, and number of storeys. The authors measured these variables in a sample of Dutch residential estates and showed how Spacemate segregates the buildings into distinct morphological types. Martin and March [1972 Urban Space and Structures (Cambridge University Press, Cambridge)] showed how three generic built forms�freestanding �pavilions�, parallel �streets�, and inward-looking �courts��make use of land in distinctively different ways, again measuring density in terms of FSI. This paper brings the two pieces of work together and shows how Martin and March�s analysis can provide further theoretical explanation for Berghauser Pont and Haupt�s empirical findings. Two additional variables are introduced: depth of buildings in plan, and cut-off angles describing the distances by which buildings are separated. A more precise morphological categorisation is then possible.
