Project Statement

Using a selection of floor plans from Public Housing Authorities across the United States as well as from the United States Department of Agriculture in Florida, this booklet provides an analysis of unit layouts of small attached housing (townhouses, duplexes, three and four-plexes). These units are the focus of Project Re-envision, a four-year research, design and demonstration project funded by the Office of Policy Development and Research, US Department of Housing and Urban Development. Specifically, the booklet focuses on the three areas that the Project Re-Envision team identified as critical to creating accessible units:

1. The transition from bedroom to bathroom 2. Kitchen and eating area 3. The conversion of the first floor of a townhouse into a suite

Using graphics and text, the following pages illustrate basic spatial patterns and dimensions, as well as highlight possible issues (number of turns, and physical and visual obstructions) as well as opportunities (space under stairs) that could be crucial in the repurposing of these units. Repurposing includes replacing or adapting problematic fixtures, or adapting existing spaces for a new purpose (e.g. converting a living room into a bedroom suite).
