Farnsworth & Chambers Building
Also known as: Gragg Building
Why it's listed
Built in 1956 at 2999 South Wayside in southeast Houston, this low, horizontal office building was the suburban headquarters of the Farnsworth & Chambers construction company. Architects MacKie & Kamrath gave it battered green quartzite walls, ribbon windows, deep canopies and a corbelled porte cochere that echo Mesoamerican pyramid forms and the work of Frank Lloyd Wright. Garret Eckbo designed the interior courtyard landscaping. Its location near the Gulf Freeway reflects the postwar move of corporate offices out of downtown. From 1962 to 1964 the building served as headquarters of NASA's Manned Spacecraft Center while the Clear Lake campus, later Johnson Space Center, was designed and built. The City of Houston bought the property in 1976 and housed its Parks and Recreation Department there, calling it the Gragg Building. The building was listed for its role in the early space program and for its architecture. At the time of nomination it stood unoccupied during a rehabilitation.
Significance in brief: The building is significant under Criterion A as the headquarters of NASA's Manned Spacecraft Center in Houston from 1962 to 1964, during the Mercury program, while the Clear Lake campus was being built. It is also significant under Criterion C as a leading example of MacKie & Kamrath's Wright-inspired modernist work, with Mesoamerican-influenced talud-tablero detailing.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
Noted as vacant in the nomination. Nomination documents can be decades old; current status may differ. If you are considering buying an empty listed property, read the due-diligence checklist.
