Donald Danforth Plant Science Center Phenotyping Headhouse Expansion

The project consisted of the expansion of the existing ‘headhouse’ to accommodate a dedicated environmental grow room and research equipment (instrumentation) to support the DDPSC phenotyping research efforts. The expansion consisted of reinforced concrete spread footings, fireproofed structural steel frame, CMU wall, and single membrane roofing. The intent of the architecture of the expansion was to match the material and detailing of the existing building. A physical connection was made to the existing ‘headhouse’ lab through the existing masonry wall. The east wall abutted the glass pedestrian connection link between the main building and the greenhouses. The project required modification to the existing glazing on the connector link.
