CARTER • DESIGN ASSOCIATES
The George Washington Carver Branch Library, located in and owned by the City of Austin, Texas, is one of many branch libraries
run by the City's Library Department. It began with the request made by the surrounding African-American neighborhood when a
new main library building was built in 1933. After outgrowing the small 1,896 sf building, the current branch library building was
constructed in 1980.
The original structure was converted into the George Washington Carver Museum and has continued to serve the Austin
community. This project remodeled and added to the 1980 facility. The Carver Library has had from its inception a unique
relationship with the surrounding neighborhood in that it has a large meeting room space and functions similarly to a community
center - hosting a variety of events such as club meetings, family gatherings, and public events.
The building is a recycled steel frame and steel stud infill with a locally manufactured masonry veneer of cement plaster and
existing brick. The foundation is fly ash containing concrete pier and beam with a poured-in-place suspended concrete slab floor. It
has built-up roofing. A new steel canopy, automatic doors, and frit glass in a thermally broken curtain wall are used as a new entry
element.
Interior finishes are minimal, durable, and easily cleaned. The existing library had brick interior walls that were retained wherever
possible. The interior has carpet tile for easy replacement of high use areas without requiring a complete replacement, thus
extending the overall life of the carpet. Both the carpet floor and acoustic panel ceilings were chosen for sound attenuation.

6. Emissions and cost are reduced by decreasing
energy use through improved design. Emissions
are further eliminated by contracting 100% of
the building’s energy to a renewable source.
