A tripling or more in the production rate of precast concrete building units utilizing reusable mold forms is achieved by casting the units vertically on a wheeled base between separable vertical mold forms. The partially cured poured concrete unit is horizontally transported on the wheeled base from between the separated molds to complete the curing independently thereof, the forms being immediately serviceable with another wheeled base for molding another unit. A building is erected on a concrete slab foundation using a plurality of precast concrete units in the form of L-shaped walls positioned as corner structure and spaced intermediate exterior wall elements and as interior partitions and roof supports. The L-shaped walls are bolted to the foundation by anchoring means located in cutout portions along the bottom of each wall and H-beams are placed to extend across the tops of the walls and are filled with concrete to serve as support and anchoring means for precast concrete roof slabs and to bridge the spaces between the concrete walls as lintels for doors and windows which complete the exterior wall enclosure of the building.
