Redwood City General Contractor plans and builds home additions across the west side of San Francisco. An addition is the answer when you love your block but have run out of room, a bigger kitchen, another bedroom or bath, a family room, or a finished suite over the garage. On a narrow, attached rowhouse the hard part is not adding the square footage; it is tying the new space into a shared-wall structure so the result looks original and the house still works. That tie-in is exactly what we plan for from the first sketch.
- Rear, upper-floor, and garage-level additions
- A clean, seamless tie-in to the existing rowhome
- Stucco, trim, and rooflines matched to the block
- San Francisco permitting and structural work covered
- One design and build team accountable throughout
The connection to the home is the hard part
Adding square footage is the straightforward part. The real work is making the new space read as if it was always part of the house. A weak addition gives itself away with a mismatched roofline, slightly off trim, an awkward floor step, or fresh stucco that never quite matches the weathered original. A strong one blends so well you cannot tell where the old house ends and the new begins.
Our additions are built to blend, with the stucco texture and color matched as closely as the material allows, the trim profiles replicated, and floor levels and ceiling heights aligned so the transition inside is seamless. On a row of attached homes where every facade is on display from the sidewalk, that matters as much for the neighbors and the resale value as it does for you.
The blending has to be worked out before the build starts, because so much of it depends on framing and structural decisions made up front. Planning the tie-in from the first sketch is what separates an addition that looks original from one that always looks bolted on.
Additions designed for your routines
An effective addition solves a specific shortcoming in how the home functions. A cramped galley kitchen that wants to open to the back, a household short a bedroom, a missing family room, or a needed ground-floor suite each calls for a different answer. We start from the real problem and design the addition around it, rather than appending generic square footage.
On a west-side lot the choice between building up, building toward the rear, or finishing the level under the main floor is the heart of the project. A rear addition can open the house to whatever light and yard the lot offers; an upper floor preserves the footprint but adds structural and access work; a garage-level build-out captures space you already own. We walk you through the trade-offs honestly so the choice fits your house, your budget, and how you want to live.
Because we plan and build the addition together, the new space meets the existing rooms cleanly, the systems carry through correctly, and the finished home works as a single whole rather than two parts joined at a seam.
Permits, structure, and a managed job
Additions involve real structural work and a full San Francisco permit process, and on an attached rowhouse the structure underneath and beside the new space often has to be reinforced. We coordinate the structural and energy engineering, produce the permit set, and oversee the inspections, so the addition is sound and on file with the city.
We also order the work to keep the home usable for as much of the project as the scope allows, and on a shared-wall home we take particular care to protect the neighbors and keep the site clean and contained. Opening the house to the new space is timed thoughtfully, which holds down the disruption to daily life.
