Custom New Homes in King County
Your new homes project, built for Sammamish homes
Good new homes work starts with the homes it happens in — and after five generations across the South Sound, we know Sammamish's.
Sammamish plateau housing is largely 1980s through 2000s, from Sahalee's golf-course homes and Klahanie's planned community to newer construction around Trossachs, with lakefront properties on Pine Lake and Beaver Lake mixed in.
Sammamish is the farthest north we regularly travel, and the work justifies it: the plateau's 80s and 90s homes have great bones and generous square footage but dated interiors, so whole-interior remodels and kitchen transformations are our mainstay here. The City of Sammamish issues permits, and many neighborhoods layer HOA architectural review on top, which we handle as part of pre-construction. Pine Lake and Beaver Lake properties add waterfront remodel opportunities on a more intimate scale than Lake Washington.

Why homeowners choose us
Custom New Homes the design-build way
Building a custom home in Sammamish is the rare chance to get everything right from the first shovel of dirt — the orientation of the living spaces, the way morning light lands in the kitchen, the room count that actually fits how your family lives. As a design-build firm, Home Renovation Design & Build carries your project from empty lot to final walkthrough under one roof and one contract. Our in-house designers model your future home in photorealistic 3D before we ever pour a foundation, so you can walk through it, adjust it, and approve it with total confidence.
We are fifth-generation builders, and that heritage shows up in the details: engineered framing packages suited to King County soil and seismic requirements, building envelopes designed for Pacific Northwest rain, and a permit process we manage entirely on your behalf with the local jurisdiction. Home Renovation Design & Build is fully licensed and insured (WA license HOMERDB750MH), and we build every home as if a sixth generation will be judging our work — because one day, it will.
One team from lot to keys
Architecture, engineering coordination, permitting, and construction all live under our roof. No finger-pointing between designer and builder — one accountable team owns your budget and schedule from day one.
Photorealistic 3D before you commit
Our in-house design studio models your entire home — elevations, rooflines, interiors, finishes — so you approve what you'll actually get, not an artist's loose sketch.
Built for Northwest weather
Rain-screen siding assemblies, properly detailed flashing, high-performance windows, and insulation packages that keep energy bills reasonable through gray Puget Sound winters.
Fixed-price contracts with transparent allowances
You'll know your investment before construction starts. Allowances for finishes are spelled out line by line, so selections never turn into surprises.
Five generations of craftsmanship
Framing that's square, foundations that are level, trim that's tight. The fundamentals get done right because our family name has been on this work for over a century.
Warranty-backed peace of mind
Every new home comes with our written workmanship warranty on top of manufacturer warranties, and we stay reachable long after move-in day.
The process
How your Sammamish project unfolds
Site & vision consultation
We walk your lot (or help you evaluate one), talk through your wish list and budget, and identify the opportunities and constraints of building in your jurisdiction.
Design & 3D modeling
Our designers develop floor plans and elevations, then build a full 3D model you can tour and revise until the home is exactly right — paired with a detailed fixed-price proposal.
Engineering & permits
We coordinate structural engineering, septic or utility connections, and submit the complete permit package, handling every correction cycle with the city or county.
Construction
From excavation through final finishes, a dedicated project manager runs the schedule, coordinates inspections, and sends you regular photo updates and milestone check-ins.
Final walkthrough & warranty
We walk every room together, complete a punch list to your satisfaction, hand over the keys, and back the home with our written warranty.
Investment
What new homes projects cost
Custom new home construction in the Puget Sound area typically starts around $350 per square foot and rises from there with complexity, sitework, and finish level — meaning most of our custom homes represent an investment of $900,000 to $2M+ including design and permitting. Every project begins with a free consultation, and we offer financing options to help structure the investment sensibly.

Custom New Homes questions in Sammamish
How long does it take to build a custom home in Sammamish?
Plan on 4–8 months for design, engineering, and permitting, then 10–16 months of construction depending on size and site conditions. We give you a milestone schedule during design so you always know where the project stands.
Do you handle the building permits?
Yes — completely. We prepare and submit the full permit package to the local jurisdiction, respond to plan-review comments, and schedule every required inspection through final occupancy. You never stand in line at a permit counter.
What does a custom home cost per square foot?
In the Sammamish area, quality custom construction generally starts around $350 per square foot and can exceed $500 for complex sites or premium finishes. After our design phase you receive a fixed-price contract, so the number you approve is the number you build to.
Can you help us find or evaluate a lot?
Absolutely. We regularly assess lots for buildability — slope, soils, setbacks, utility access, and critical areas — before clients purchase, which can save you from an expensive mistake.
What warranty comes with a new home?
Every home includes our written workmanship warranty covering the first years of ownership, plus manufacturer warranties on systems, windows, roofing, and appliances. As a licensed and insured builder (HOMERDB750MH), we stand behind what we build.
