Sunnyvale General Contractors plans and builds home additions throughout Martinez and central Contra Costa County. An addition is the answer when you love your home and your street but the house has run out of room, for a bigger kitchen, another bedroom or bath, a real family room, or a full second story. The hard part of an addition is never the extra square footage. It is tying the new space into the existing home so the finished result looks and feels like it was always there. That tie-in is exactly what we plan for from the very first sketch.
- Room additions and second-story builds
- A clean, seamless connection to the existing house
- Rooflines, siding, and trim profiles matched
- Permitting and the structural engineering handled
- One design and build team accountable for the result
The connection to the house is the hard part
Adding square footage is the straightforward part of an addition. The real work goes into making the new space read as though it was always part of the home. A weak addition announces itself with a roofline that does not quite line up, trim that is slightly off, a floor that steps where it should be flush, or an exterior that looks too new next to the weathered original. A strong addition blends in so well that a visitor cannot find the seam where the old house ends and the new begins.
Our additions are built to blend. We match the roof pitch and the eave detail, replicate the siding and the trim profiles, and align the floor levels and ceiling heights so the transition inside is seamless underfoot and overhead. On an older Martinez home that means studying the original details closely, because a stock modern profile next to hundred-year-old casing never quite passes.
That blending has to be worked out before the build starts, because most of it depends on framing and structural choices made up front. Planning the tie-in from the first sketch is what separates an addition that reads as original from one that always looks like a box bolted onto the back of the house.
Additions designed around how you live
An effective addition solves a specific problem in how the home functions. A cramped galley kitchen that wants to open up, a household that has outgrown its bedrooms, a missing family room, or a needed ground-floor suite for aging parents each calls for a different answer. We start from the real shortcoming and design the addition to fix it, rather than tacking on generic square footage and hoping it helps.
On many Martinez lots the choice between building out and building up genuinely matters. A ground-floor addition is simpler to build but spends yard you may want to keep; a second story preserves the lot but adds structural reinforcement and access complexity below. We walk you through those trade-offs honestly so the decision fits your lot, your budget, and the way you actually want to use the home.
Because we plan and build the addition with one crew, 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 halves joined at an awkward seam.
Permits, structure, and a managed job
Additions involve real structural work and a full permit process, and second stories often require the structure underneath to be reinforced before anything new goes up. We coordinate the structural and energy engineering, produce the permit set, and manage the inspections, so the addition is sound and on record with the city or county.
We also sequence the work to keep the home livable for as much of the project as the scope allows. Opening the existing house to the new space is timed deliberately, and we protect the rest of the home and keep the site clean while we work, which holds the disruption to daily life down to what the job genuinely requires.

Why one crew for the whole project matters
A home is a design-build project, so home additions rarely stands alone, it connects to basement finishing, custom carpentry, a general contractor, renovating the whole home, remodeling your kitchen, and our crew handles all of it as one accountable team. We bring the same service to Home Additions in Pleasant Hill, Home Additions in Concord, Pacheco home additions, Home Additions in Walnut Creek and everywhere else across the Martinez area.
