New Custom Homes
We build a brand-new home on your empty lot. Every room, every window, every finish is chosen by you and built by us.
Tear-Down and Rebuild
Some lots come with a house past saving. We take it down and build the right home in its place. You keep the land and the location you love.
Multigenerational Homes
We build homes that fit real modern families. Think a main home plus an ADU, or a ground-floor suite for parents. See our ADU page.
Homes for Tough Lots
Sloped sites, view lots, and tight infill parcels do not scare us. We engineer for the land and build to last.
Why Build Custom?
A custom home is the only home built around you. Not the last owner. You choose the layout, the light, the flow, and every finish. You get the home you want, in the town you want, with nothing you have to fix later.
What Determines a Custom Home’s Cost
No two custom homes cost the same, because building from the ground up means starting from a bare lot’s real conditions, not an existing structure.
Lot condition drives much of it. A tear-down adds demolition before anything new begins. A raw lot often needs new utility hookups, grading, and civil engineering that an existing home’s lot already has in place.
Site engineering complexity matters just as much as square footage. A flat, easily accessed lot is straightforward. A sloped or view lot typically needs a geotechnical soil report, engineered foundations, and retaining structures that a flat lot never requires.
Size and finish level factor in last, but they’re not the starting point, the site is. This is why we walk your lot and understand what it actually requires before any number gets discussed.
How It Works
The First Call or Email
Tell us about your lot, or the lot you’re considering, and the home you’re picturing. We ask about your timeline and vision, then schedule a free site visit if it’s a fit.
The Site Visit
We walk the lot itself, raw land or a home to be torn down, and assess slope, access, existing utilities, and what the site will require before any design work begins.
Design and Permits
Ground-up construction needs full architectural plans, structural engineering, and civil engineering, grading, drainage, and utility connections, along with Title 24 energy documents. Sloped or view lots typically require a geotechnical soil report before foundation design can proceed. We scope the full drawing and engineering package to your specific lot.
Proposal and Permit Submittal
We bring the plans back to the office and review the full scope with our construction team. Once you approve it, we submit for permit, new construction typically takes longer for city review than a remodel, and we handle every question that comes back.
Construction
Our dedicated crews build from the foundation up, with regular progress updates throughout. We close with a final walkthrough, a completed punch list, and a one-year workmanship warranty.

Common Questions about Custom Homes
How long does it take to build a custom home?
Most custom homes take twelve to twenty-four months, including design, permits, and construction. The lot and the design drive the timeline.
Do I need my own lot?
Yes, or a home to tear down. We can build on a lot you own or one you are buying. We can look at the lot with you before you buy.
Do you help with design and architecture?
Yes. We work with trusted architects and engineers on every build. Or we build from plans you already have.
Can you build on a difficult or sloped lot?
Yes. We engineer foundations for sloped and complex sites across the East Bay.
Do you handle permits?
Yes. We manage the full permit process with your city, start to finish.
