The 1878 structure was a -story red-brick structure with a center building for offices and staff, and two wings for male and female patients. The building had a steeply pitched slate roof with multiple towers, and wood and metal cornices. The building resembled a typical Kirkbride model. The 1882 additions were designed by Charles Anderson to match the original construction. The 1906 and 1914 additions were brick hipped-roof structures, and the 1938 construction added a Tudor designed building onto the front of the structure.
