What's in the Works

Harvest Properties, in partnership with the City of San Mateo and Alta Housing is proposing to transform the full City block at the end of the B Street retail corridor into a vibrant, mixed-use destination for locals and visitors alike.

The proposed project is comprised of 2 separate buildings connected underground by a parking garage containing 128 spaces. The first building, which fronts 4th Avenue, is a a seven-story, 100% affordable housing building consisting of 71 units. The second building, which fronts B Street, is a six-story commercial building of approximately 155,000 square feet including 12,000 square feet of ground floor retail space.

The residential building will incorporate family-friendly apartments with a mix of studios, 1-bedroom, 2-bedroom, and 3-bedroom units along with a private, elevated courtyard and amenities area for residents to enjoy. Additionally, a portion of the ground-floor includes a long-term home for the local non-profit organization, Self-Help for the Elderly.

Bespoke contains 12,050 square feet of quality retail spaces along B Street and 4th Avenue.



The commercial building will be constructed using regenerative mass timber which has low carbon emissions, allows for faster construction due to it's prefabricated and modular nature, resulting in less waste.



The Bespoke project concentrates jobs around transit, mitigating traffic concerns in the Downtown area by implementing a best-in-class Transportation Demand Management Plan and traffic calming measures.



Bespoke is located in close proximity to the Caltrain depot, connecting it to the rest of the South Bay Area, Peninsula, and San Francisco regions, and de-incentivizing the use of cars downtown.
