St. John’s Episcopal Cathedral is a historic church near downtown Los Angeles, built in 1925 in the Romanesque Revival architectural style and constructed primarily of exposed concrete. The new Residences at St. John's Cathedral expands upon the church's existing facilities, the most significant of which is the addition of a new nine-story multifamily residential building. The concept design also includes the addition of a new parish hall, kitchen, administrative offices, music practice rooms and library. The u-shaped plan accommodates lobbies and residential amenity spaces with access to shared outdoor space, and the building massing enhances the presence of the historic cathedral along Adams Blvd. by respectfully framing the structure on either side.

The new construction is proposed as a similar exposed, cast-in-place concrete building as the church, with warm wood accents to add warmth and scale. Additional outdoor space is provided on rooftop terraces with views to the downtown skyline.
