The Walnut Street development is proposed to be a new four-story, mixed-use residential building across three existing lots at 626, 640 and 648 Walnut Street. The project will feature 28 residential condominiums and two commercial spaces with a rear parking garage at street-level. The condominiums are generously-sized with three bedrooms and three and one-half baths each and can easily accommodate families.

The proposed project is designed to enhance the existing downtown corridor and neighboring residential buildings, while providing new residents with walk-, bike- and commute-friendly housing. The new condos will help address San Carlos housing needs and complement Walnut Street with amenities including two new sidewalk-facing commercial spaces and a beautifully designed public open space at the middle of the building. The project is a high-density urban infill project designed to enhance the streetscape, provide housing and reduce environmental impacts through innovative design and construction.
