Developed by Greenroof LLC and designed by Studio Ma, PRD 845 is an urban infill project in Downtown Phoenix , adjacent to the Roosevelt Historic and Arts Districts. A sensitive cluster of twelve condominium homes, this enclave is organized around two, private “mews” that mix cars and people in an intimate and compelling urban-type environment.

Unit sizes range from 900 to 2,200 square feet and are designed to accommodate an active, live-work life style with ground floor garage / studio spaces and large outdoor roof decks with views of downtown Phoenix and the surrounding mountains. The folded roof plane creates volumetric slots through the complex giving PRD its unique, “skyline” profile.

Carefully chosen building materials compliment the south-west desert environment and include an innovative rain-screen design wall design made of a low mass, corrugated, fiber-reinforced concrete panels on furring channels that allows accumulated heat to escape through a slot at the top of the wall.

PRD845 is the recipient of a 2008 AIA Merit Award, and 2009 Chicago Athenaeum American Architecture Award.
