Level City

Many people assume that in order to achieve a compact, sustainable, prosperous city, it is necessary

Evidence indicates that one of the most optimal urban forms is a relatively continuous building volume with a height of between two and ten stories – what we may call the “level city”. Yet in the last half-century, many cities have taken on a discontinuous and disruptive form, with significant long-term negative impacts on the quality and resource efficiency of city life.

Therefore:

Maintain a building height limit of typically no more than ten stories, together with incentives for maximizing infill of buildable sites, aiming to produce a continuous and efficient urban form. Allow taller structures when they are civic monuments and public buildings, and when they assist with wayfinding. Allow variations in density, while assuring a continuous walkable urban fabric.
