Located in the heart of the Tenderloin district of San Francisco, this 100% affordable housing building for seniors is comprised of twelve stories with 101 1-unit bedroom units and ground floor senior center services. Working with the owned and operated building by TNDC (Tenderloin Neighborhood Development Corp), known for their work of improving communities and providing more affordable housing to the undeserved Tenderloin neighborhood, we were given the opportunity to work on this building providing major renovations. A full building interior and exterior renovation, offering new exterior windows, exterior façade improvements including a new fresh exterior color scheme, complete unit finish upgrades and common spaces, a new addition providing more ground floor service spaces, and complete mechanical, electrical, and plumbing upgrades with an integrated solar thermal system on the roof.
