Quadrangle Housing, Washington University’s rental apartment agency, is looking to expand its current portfolio by developing a fleet of new construction housing. In this studio, we worked as a collective office to develop and propose affordable and profitable NetZero multi-family residences. Considerations included making best use of the F.A.R and zoning conditions, market research, communal amenities and projected costs to reinforce a sustainable future for the community.
Form and Facade Iterations
In this third installment of Donks and Dyads, our goal was to propose new construction housing on vacant lots in University City for Washington University’s Quadrangle Housing. Part of the challenge was to identify how to maximize bedrooms, within the various zoning requirements, including parking limitations to provide our client with the most energy efficient, economically responsible and useful living conditions for their renters. In order to maximize the number of parking spaces possible on the site, the back half of the building was lifted up to accommodate tuck-under parking, allowing for 6 parking spaces.

On the first level, there is a one bedroom ADA accessible apartment, as well as a mechanical room to service the building’s water, air, internet, and gas requirements. On each of the second and third floors are a three and two bedroom unit. In every unit, the shared living spaces are located on the western façade allowing views onto the street and daylight during the second half of the day when students are most likely in these spaces. The bedrooms face east, towards the quieter alley and where they can benefit from morning daylight. Between the public and private zones is a utility core from which water lines and ventilation simply run from the first level up to the roof.
