This expansion of San Leandro WPCP’s  existing Administration and Control Building provides much-needed space for existing functions, while respecting and celebrating the adjacent iconic WPA-era process buildings. A new lab, structural upgrades, modernized control and office spaces, and new Mechanical and Electrical Systems were provided. Updated exterior cladding and sun control elements tie together the addition and renovated parts of the project, while an interior courtyard provides a shared outdoor space for plant staff.

Materials were selected for their compatibility with the existing building and the WPA era process structures, low maintenance and sustainable attributes. The renovation and expansion is LEED Silver-certified. Sustainable design elements include reuse of the existing structure, skylight day-lighting, sunshades and a high efficiency HVAC system with heat recovery.
