Home Additions · East Bay, California

More home.
Seamlessly added.

A good addition should look like it was always there. We design new space to match the proportions, materials, and roofline of your existing home — and show you the join in render before we build it.

The difference between an addition
and something bolted on

It Has to Match
The tell of a cheap addition is the seam — a roofline that does not resolve, siding that almost matches, proportions that feel off. We design new space to marry the existing architecture so the finished home reads as one coherent building. Getting that join right is craft, and it is exactly where an integrated design-build team earns its keep.
Structure Is the Hard Part
Adding a room or a second story means tying new structure into old, and that is where additions get expensive and slow if handled carelessly. Our engineering and construction teams plan the structural connection together, up front, so load paths, foundations, and framing are solved on paper long before they become a problem on site.
See the Join Before You Build It
We render the expanded home in photo-realistic detail, including exactly how the new work meets the old. You see the finished elevation and interior before demolition, approve how it all comes together, and build with confidence that the addition will feel original rather than appended.

New space that belongs
to the home it joins.

1
Feasibility

What your lot and your house will allow

Additions are shaped by setbacks, existing structure, and how the new space can connect to the old. We assess all of it first so the design we develop is buildable, not just attractive. This early honesty keeps the project from stalling later on something that could have been caught at the start.

2
Integrated Design

New architecture drawn to match the existing

We design the addition to extend your home's proportions, materials, and rooflines, and we do it with the builders in the room so the structural connection is solved as the design develops. The goal from the first sketch is a home that looks like it grew naturally rather than gaining a bolt-on.

3
Render & Price

See the finished home, then get a real number

You review the expanded home in photo-realistic renders, inside and out, and refine until the join reads seamlessly. We then issue line-item pricing for the full scope, including the structural tie-in, so there are no mid-project surprises where the new work meets the old.

4
Build & Blend

Executed so the seam disappears

Our crews build the addition and integrate it into the existing home with careful attention to the transitions — the matched materials, the resolved rooflines, the finishes that carry through. We close with a walkthrough against the renders so the completed home feels whole, not extended.

An addition should be
invisible in the best way.

The measure of a great addition is that a visitor cannot tell where the original home ends and the new work begins. Achieving that takes design and construction working as one from the beginning, which is exactly how we operate on every project, at every scale.

Adding to your home, answered

How do you make an addition look original rather than bolted-on?

We design the new space to marry your home's existing proportions, materials, and rooflines, and we render exactly how the new work meets the old before building. The seam is where cheap additions give themselves away, so resolving that join is where we focus.

Is a second-story addition possible on my house?

Often, but it depends on the existing foundation and framing and on your lot's constraints. We assess feasibility first, including the structural tie-in, so the design we develop is genuinely buildable rather than an attractive plan that stalls later.

Who handles the structural engineering for tying new to old?

Our engineering and construction teams plan the structural connection together, up front, as part of one integrated firm. Load paths, foundations, and framing are solved on paper long before they become a problem on site.
