Walnut Creek Whole-Home Remodeling & Additions
Walnut Creek's ranchers — Northgate, Rudgear, Saranap — were built low and single-story, which makes them ideal candidates for open plans and true indoor-outdoor living. A whole-home remodel in Walnut Creek often takes a good structure and simply lets it breathe. We carry the whole job — design, permits, and construction — on one team, one schedule, one fixed proposal.
We Do Construction opens up Walnut Creek’s 1950s ranchers — whole-house transformations, kitchen and primary-suite remodels, and indoor-outdoor conversions built for the owners who stayed. One team carries design, fully online permitting through Walnut Creek Community Development, and construction on one schedule and one fixed proposal.
Who We Build For in Walnut Creek
Homeowners Planning to Stay Long-Term
This is the house you’re keeping. You want it re-systemed, structurally sound, and reorganized to live the way you actually do — done once, comprehensively.
Growing Families
The house has to grow with the family — more space, a real kitchen, a better connection to the yard. We sequence the work and, where possible, keep part of the house livable.
Owners of Ranch & Mid-Century Homes
You own a solid Walnut Creek ranch and want it brought current — systems, layout, and a kitchen — without losing the single-level livability that works.
What should Walnut Creek homeowners know before remodeling a rancher?
The rancher is Walnut Creek's signature house: single-story, low-slung, built across Northgate, Rudgear, and Saranap in the postwar decades. That form is a gift to remodelers — with no second floor to fight, walls open readily into great rooms, and rear elevations convert to glass and covered outdoor living with relative ease. In Rossmoor, the demand runs toward aging-in-place: zero-threshold showers, wider circulation, single-level living refined rather than reinvented. Walnut Creek Community Development handles permitting fully online, from submittal through inspection scheduling, which keeps well-prepared projects moving. Whether the goal is a kitchen remodel or a home addition in Walnut Creek, the city's housing stock gives a design-build team unusually good bones to work with.
We Do Construction (CSLB #1096552) is a design-build contractor for exactly this work — one team carrying design, permits, and construction to a fixed proposal. What would your rancher look like opened up? Worth a conversation.

SIGNATURE MOMENTS
What separates a full remodel from a series of renovations.
Whole-home coordination
Plumbing, electrical, and HVAC designed together — not retrofitted room by room. Systems that work as a single home.
Live-in sequencing
We phase construction around your occupancy when possible. You don't always have to leave for a full remodel.
Single-team delivery
One GC. One point of contact. No finger-pointing between trades when something needs resolution.
ENGAGEMENT MODEL
Three phases. Every room. No handoffs.
Flat-fee at every phase. You know the total investment before work begins.
PHASE 01
Discovery
We assess your entire home — structure, systems, layout — and align the scope to how your household actually lives.
PHASE 02
Design
Integrated design across every room. Finishes, fixtures, and spatial flow resolved together so nothing conflicts.
PHASE 03
Construction
Phased execution across all spaces, coordinated by one team. You stay informed at every milestone.
Architecture & Floor Plan
Opening a dated ranch to light and the yard, or adding square footage on a generous Walnut Creek lot, is where the value is.
Structure & Foundation
Established Walnut Creek homes can hide undersized framing and dated foundations, and hillside lots add drainage realities. We engineer the fixes into the scope, not the surprises.
Systems: Electrical, Plumbing & HVAC
Dated panels out, modern service in; re-plumbed supply and drains; heating and cooling sized for the whole house — done while the walls are open.
Finishes & Millwork
Rift-sawn white oak, honed stone, custom millwork — specified and detailed before demolition so the trades build to a drawing.
The Old Way
- Separate designer and contractor
- Unclear budgets and change orders
- Delays caused by poor coordination
- Limited accountability when problems arise
Our Design-Build Approach
- One integrated team from concept to completion
- Clear scope, transparent pricing, and realistic timelines
- Fewer delays and better communication
- Full responsibility for design, permits, and construction
Why Build in Walnut Creek
Increase Property Value
On a Walnut Creek lot, a permitted, structurally documented remodel, addition, or build is the value move — the value is in the structure, systems, square footage, and approvals, not a surface refresh.
Improve Daily Functionality
A plan that finally fits the family, light brought in from the rear, and a house that works as one — the difference between patching and actually solving the house.
Modernize the Look and Feel
Consistent materials and detailing across every room — a house that reads as one considered project rather than a decade of piecemeal fixes.

What to Expect Building in Walnut Creek
A full remodel or addition in Walnut Creek is a real permit — structural, electrical, plumbing, and City of Walnut Creek planning review for new square footage or exterior changes. Plan on design, a review window, and several months of construction. We file the set with the City and carry it through every inspection.

Increase Property Value
A whole-house renovation done right is the biggest value move a home here can make — but the value is in the structure, the systems, and the permits, not a surface refresh.

FAQ
Yes — a remodel, addition, or build means a structural permit set with the City of Walnut Creek, plus planning review for new square footage or exterior changes. We file it, manage the review, and carry the job through every inspection.
Typically several months of design, a review window with the City of Walnut Creek, and several months of construction — longer for a large addition or a down-to-studs remodel. We give you the real schedule in feasibility.
For phased or partial-scope work we can often keep part of the house livable. A full down-to-studs remodel is safer and faster with the house empty.
It depends on square footage, how much structure and systems work is involved, and the finish level. We price it in feasibility against a real scope, then hold it in a fixed proposal.
Both. We are design-build — architecture, engineering, permitting through the City of Walnut Creek, and construction on one team and one contract.
Yes — we handle the planning review and engineering for additions and ADUs as part of the scope.
Yes — Walnut Creek and the surrounding communities. Each project files with the jurisdiction that governs it.
Yes. After feasibility and a defined scope we issue one fixed proposal covering design, permits, and construction.
How much does a full home remodel cost in San Francisco?
A full home remodel in San Francisco typically runs $350,000–$900,000+ in 2026 — roughly $300–$600 per square foot, and higher when structural or seismic work is involved. The range reflects SF labor rates, the realities of pre-1978 housing stock, and the finish level of a design-build home. We Do Construction (CSLB #1096552) delivers whole-home remodels across San Francisco on a single fixed-price design-build contract.
| Tier | Typical SF range (2026) | Scope |
|---|---|---|
| Finishes-forward | $350,000–$500,000 | Existing layout kept, new kitchen and baths, finishes, systems refresh |
| Full reconfiguration | $500,000–$750,000 | New floor plan, relocated plumbing and electrical, Title 24 systems |
| Structural / addition-grade | $750,000–$900,000+ | Walls out, steel and seismic upgrades, custom millwork throughout |

What permits does a full home remodel require in San Francisco?
A whole-home remodel touching layout, structure, plumbing, electrical, or mechanical systems requires a building permit from the SF Department of Building Inspection (DBI), and work that changes the building envelope or use also goes through SF Planning. Full-scope and structural permits run 2–4+ months in plan review, and additions 3–6 months; historic districts north of California Street add design review. Pre-1978 homes also trigger lead and asbestos protocols. As a licensed SF general contractor (CSLB #1096552), We Do Construction files and manages the entire DBI and Planning process in-house.
