An important parish church and chancellory, St. Basil Catholic Church is adjacent to the Wilshire Synagogue and within the former Ambassador Hotel - Wilshire Center Community. The church proper contains approx. 40,000 SF of space and seating for 1000 people. The main church contains a nave, sanctuary, narthex, sacristies, choir and organ lofts, baptistry and a carillon tower is integrated within the basic structure itself. Supporting facilities include a chancellory office, parish library and full rectory. Parking is provided for 220 cars.

The basically rectangular plan used for the body of the church is enclosed by undulating exterior walls of massive concrete slab forms, which are separated by full height shafts of a three-dimensional, stained glass and ornamental iron grid of unique sculptural quality and effect. The architectural concept recalls the Early Christian and Romanesque forms of construction, and interior finishes include rough natural concrete and full height hardwood surfaces.
