Project Overview
The adaptive reuse project at the former World Trade Center / 333 Flower Street in Downtown Los Angeles involves converting an underutilized office complex into a large affordable housing development under the City’s expanded Adaptive Reuse Ordinance. The redevelopment proposes converting the largely underutilized office tower into 512 units of 100% affordable housing. The project is being highlighted by the City of Los Angeles as a model for office-to-residential conversion following the expansion of the ordinance citywide in 2026.
Project Scope
The project will consist of adaptive reuse of an existing office building to a 13 story, 512-unit apartment building located at 333 Flower Street, Los Angeles, California. Total building area is 291,224 sq. ft.
