Williams Terrace won the 2019 AIA/HUD Secretary's Housing and Community Design Award for Excellence in Affordable Housing Design. This singular nation-wide award recognizes architecture that demonstrates overall excellence in terms of design in response to both the needs and constraints of affordable housing.

The inspiration motivating the Charleston Housing Authority.

Williams Terrace Senior Housing is the first dedicated housing for low-income seniors in the city of Charleston, South Carolina. DBA collaborated with local firm McMillan Pazdan Smith to create this gracious senior building, which finally replaces affordable family housing destroyed in a 1989 hurricane.

The design team worked closely with the Housing Authority of the City of Charleston to create a dynamic building that meets the challenges of the site—located in a high-velocity flood zone—and respects the gracious built fabric of downtown historic Charleston.

The building features external circulation—deep porches that create opportunities for connection and are lined with exterior seating to encourage interaction among the residents. The building’s units, porches, and rooftop terrace community room enjoy views across the new park toward the Charleston harbor.

Gadsdenboro Park

The building’s ground-level “screen porch” fronts the new public park and connects directly to it via a shaded public sidewalk. This allows for an active ground floor despite the City requirement that no permanent uses can be located at ground level. The restriction arises from the  being a flood zone, with a velocity component, so all at-grade uses need to be impermanent and able to be swept away cleanly in case of a hurricane.

Piazzas

Charleston "Single Houses" are characterized by their open-air piazzas, which function in a similar way to porches. For the corridors of Williams Terrace, we interpreted this concept with wide, open-air corridors that function as gathering and social space for the senior residents.

The courtyard is ringed by wide porches inspired by Charleston's traditional single house "piazzas." The porches are dotted with wooden rocking chairs and have movable slatted shades to protect from the sun over the course of the day. Image: Chris Luker

Shutters

Taking a cue from the historic louvered shutters found on Charleston’s piazzas, we included sliding screens to allow residents to adjust the amount of shade desired. These dynamic louvers make for an ever-changing façade. The lime-washed brick exterior offers another connection with Charleston’s historic past.

Rooftop Terrace

To avoid flood damage, the community room is located on the roof, which frames wonderful views across historic Charleston.

Shotgun Apartments

The one bedroom apartments are version of the southern "shotgun" typology: living areas fronting the circulation porches, the "piazzas", with bedrooms facing out. This allows for great social interaction for the senior community, and through ventilation in every unit.

Apartments connect to the wide circulation porches, which have room for some personal touches. Image: Chris Luker
