High-rise business district urbanism
European precedent for CBD planning
The successive masterplans for La Défense, steered from 1958 by the public development agency EPAD, transformed a ring of suburban land west of Paris into a purpose-built high-rise business district. The scheme's key device was a vast pedestrian deck or dalle running along the axis of the Champs-Élysées, with roads, rail and parking layered beneath and office towers, housing and public spaces above, later terminated by the Grande Arche.
La Défense became the principal European precedent for planning a central business district outside the historic core, protecting the fabric of Paris while concentrating corporate high-rise development on a controlled site. Its slab-and-deck urbanism influenced business-district projects across Europe and beyond, and it remains central to debates about state-led development corporations, monofunctional office districts and the retrofit of podium cities.
