The Project Brief and Scope
Expanding and Modernizing a Mid-Century Home for Growing Families in Fremont, California
The original 1,270-square-foot home featured a compact three-bedroom, one-bathroom plan with compartmentalized living areas and outdated utilities. A 757.30-square-foot rear addition and 23-square-foot covered foyer re-engineer the home around a private primary retreat, two new bathrooms, a bright island kitchen and a coffered great room that opens directly to the rear lawn.
Scope of Work
Add a 757.30-square-foot rear wing with a private primary bedroom suite, walk-in closet and en-suite bathroom with a walk-in shower.
Reconfigure the original three-bedroom, one-bathroom plan into a versatile four-bedroom, three-bathroom single-story residence.
Create an open island kitchen, dining area and 9-foot coffered great room with sliding-glass-door access to the backyard.
Add a 23-square-foot covered entry foyer and update the front façade, exterior windows and entry doors.
Modernize the home with NFPA 13-D fire sprinklers, a seismic gas shutoff valve, Title 24-compliant HVAC and a 200-amp electrical service.
Site, Planning and Blueprint Strategy
A Compliant Expansion Maximizing Backyard Living Within Fremont, California R-1-6 Zoning
Designed under City of Fremont R-1-6 single-family zoning requirements, the addition extends into the 10,105-square-foot lot while maintaining the standard 25-foot rear setback and required side clearances. Proposed lot coverage increases from 17.87% to 25.49%, while the 20.06% floor area ratio remains well within the allowable threshold and preserves substantial permeable yard area. The coordinated drawing set includes existing and proposed site plans, floor plans, elevations, sections, opening schedules, foundation plans and roof framing plans.
