On the 165 acre Bloomingdale campus of NewYork-Presbyterian Hospital, daSILVA has been engaged to convert an existing historic gymnasium, built in 1924 and designed by Grosvenor Atterbury, into a new facility for the evaluation, diagnosis and treatment of outpatients with autism. The existing building contains approximately 22,000 gsf of space on 2 levels. The main gymnasium space will be designed as a “treatment village”, with activity and consultation rooms flexibly outfitted so as to be used by small children and toddlers as well as by adolescents and young adults. Activity spaces will arranged in groupings with distinct 3 dimensional shapes with roofs and doors and windows opening into joint circulation zones within the larger day lit space. Color, size, shape, texture and light will all be used to create active spaces and as a way finding tool for patients and families. A healing garden, clock tower, large windows, and brightly painted roof trusses will enliven this activity/treatment area. Existing elements such as wood roof trusses and historic light fixtures will be refurbished and utilized in the new facility. Newly designed space for researchers who will be actively involved in the day to day treatment and evaluation processes in included in the program. The renova¬tion is being designed for LEED Silver accreditation and will include geothermal energy as well as NYSERTA credits.
