It was designed by the Houston architectural firm MacKie & Kamrath, with landscaping by Garret Eckbo.","why_significant":"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.","narrative":"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.","period_of_significance":"1956; 1962-1964","architect_builder":"MacKie & Kamrath, architects; Garret Eckbo, landscape architect; Farnsworth & Chambers, general contractor.","architectural_style":"Modern Movement/Wrightian","criteria":["A","C"],"status_note":"At the time of the form the building was unoccupied and undergoing a rehabilitation led by Harrison Kornberg Architects, with completion proposed for October 2009.
