This regional interpretation of the Shingle Style was characterized by the use of shingles and stained wood and picturesque changes in spatial and axial arrangement. Its major practitioners were Ernest Coxhead, Willis Polk, Bernard Maybeck and Julia Morgan. The skillful execution of the design of the Mission Neighborhood Capp Street Center makes it a significant expression of this genre." The building is a two-and-a-half-story wood-frame structure.
