San Jose, California Project Brief and Scope
Expanding a San Jose, California Home Into a 5-Bedroom Family Residence
The approved design removes the existing 356-square-foot rear sunroom and replaces fragmented interior spaces with a coordinated front-and-rear expansion. The conditioned living area grows from 1,300 square feet to 2,385 square feet while the existing 442-square-foot garage remains. The new plan provides five bedrooms, 3.5 bathrooms, an open kitchen and dining area, a 10-foot-high family room, a separate living room, dedicated laundry, walk-in pantry and a primary suite with a walk-in closet.
