Function Follows Form – This Version: October 9th, 2015 – Kristof Dascher1 Abstract: Urban policy visibly molds urban form. This paper’s interest is in how (if less visibly) urban form molds urban policy. The paper presents two concepts of urban form – the skewness of the city’s shape as well as the convexity of the urban skyline – that frame the political economy of the decision to end the city center’s function as commercial heart of the city. This theme – of how urban form pins down city functions – rivals the proverbial form follows function (Sullivan (1896)) prominent in architectural theory. Function also follows form. This theory the paper then applies to the effects of building height limitations, city center zoning, green belts, central city housing destruction, and to the origins of jurisdictional merger and sprawl.

When commenting on Paris’ urban development, Alexandre Gady, a historian of that city, appears to suggest the reverse though: “Paris – it’s beautiful. But it’s a doll’s house! And that’s one reason the Parisian élite is so conservative.
