Copenhagen has a become a bicycling city, but it was originally built around walking and horse-drawn transportation. Meanwhile, the redevelopment district of Orestad, just South of the city, has been struggling to attract development capital and apartment buyers. Developers have resorted to the tried-and-false tactic of basement car parking. We imagine sites furthest from the train station, but nearest to the city by bike, being developed with building types that allow people to ride all the way home to their apartments, and move between shops on their bikes. Roof tops and the ground plane would be sites for a full range of recreational pastimes, mostly two-wheeled. And there would be no car parking at all, except for a few share-cars at the site edge.
Crude numbers: the rectangular site of slip-blocks only 350m x 500m, and has an FSR of 1.3:1. Roughly 5000 people would live here. The width of the avenues is roughly the width of Park Avenue New York, or the streets with canals in Amsterdam. A whole district built up in the way would have 25,000 people per square kilometre.
