Guasti Office Building

The Guasti Office Building Project is a part of a 50 acre, mixed-use development located in Ontario, California, offering retail, restaurant, entertainment and office space. Founded in 1904, Guasti was once a self-sufficient community and the world’s largest contiguous vineyard, composed of over 5,000 acres.

The Office Building 1 is situated in the heart of the Guasti development and is a 110,00s.f. LEED Silver, office building which utilizes an elegant Ipe Wood shading structure. The building’s three other sides are a customized tilt wall system with a low overhanging roof. The lobby’s interiors are open with exposed glue lam beams sophisticatedly coordinated with the exposed HVAC.

Douglas Architects, Inc., as the Architect of Record, in collaboration with Gensler Architects, is providing design as well as project management services leading a team of eight professional consultants for the client, Oliver McMillan.
