Custom homes, additions, retaining walls and remodels across Bellevue and the Eastside — design, structural engineering and permitting handled in-house, every trade self-performed by our own crew.

What we build in Bellevue

  • New Construction

    Custom homes like our 4,500-square-foot Bellevue build — 5 bedrooms, 4.5 baths — designed, engineered and permitted in-house and built by our own crew.

  • Pavers & Concrete

    Retaining walls and hardscape for sloped Eastside lots — our 200-foot Bellevue CMU retaining wall went up in 8 days — with drainage designed for Puget Sound rain.

  • Engineering & Permitting

    Sloped lots often need geotechnical input and engineered retaining walls; our in-house team produces the structural engineering and carries it through City of Bellevue Development Services.

  • Additions & Renovations

    Additions and whole-home remodels across Bellevue and the Eastside, tying new framing into old and bringing mechanical and electrical up to code.

  • Basement Conversions

    Basement finishes like our Redmond basement theater — egress, moisture and ceiling height solved before the finish work starts.

  • ADUs & Garages

    Attached and detached ADUs designed and permitted under Bellevue's rules, built as one package.

  • Kitchen & Bathroom Remodels

    Our own crew runs the plumbing rough-in, electrical, tile and cabinetry, with a complimentary 3D design model before demolition.

  • HVAC, Plumbing, Electrical

    Heat pumps and tight envelopes under the Washington State Energy Code, self-performed by our crew rather than brokered out.

Permits and codes in Bellevue

Bellevue building permits go through the City of Bellevue Development Services. Our in-house engineering and permitting team produces the plan set and the structural engineering and carries the application through submittal, review and inspections.

Sloped Eastside lots often need retaining walls and geotechnical input before a house, addition or driveway can go in — our Bellevue CMU retaining wall and the Mercer Island clearing and soldier-pile wall are both examples of that early site work. The codes in force are the Washington State Building Code and Energy Code: seismic hold-downs, heat-pump and insulation requirements, and flashing and drainage details sized for 40 inches of annual rain.

Building in Bellevue: what to know

Bellevue is our Eastside premium market: permit and impact fees, inspection lead times, tight lots and finish expectations here run above our Puget Sound baseline, and sloped lots are common. Many projects start with site work — a geotechnical report, an engineered retaining wall or shoring, and drainage designed for 40 inches of rain a year — before the house, addition or driveway can go in.

Our 4,500-square-foot Bellevue new construction (5 bedrooms, 4.5 baths) and the 200-foot Bellevue CMU retaining wall our crew built in 8 days show both sides of that work, and nearby jobs in Redmond and on Mercer Island round out the Eastside portfolio. Design, engineering, permitting and every trade come from one crew, so there is one schedule and one accountable builder from the first sketch to the final inspection.

Neighborhoods and nearby cities we serve

From Bellevue the same crew serves the rest of the Eastside — Mercer Island, Redmond, Kirkland, Issaquah and Newcastle — with recent jobs on Mercer Island and in Redmond. Across the lake we cover Seattle, and our headquarters is in Federal Way in South King County.

Bellevue remodeling and building FAQ

A simple remodel permit is typically faster than new construction, an addition or an ADU, which can take several weeks to a few months in review at City of Bellevue Development Services; projects on sloped lots may add a geotechnical review. We submit complete, stamped plan sets to keep correction cycles short and track the application through inspections.

Usually a geotechnical report, an engineered retaining wall or shoring, and drainage designed before the foundation goes in. Our Bellevue CMU retaining wall — 200 feet in 8 days — and the Mercer Island soldier-pile wall show the kind of site work that makes a hillside buildable; our in-house engineers handle the design.

Bellevue and the Eastside sit in our Eastside premium zone — permit and impact fees, inspection lead times, tight lots and finish expectations run about 20% above our Puget Sound baseline in Federal Way and South King County. The estimate calculator prices your ZIP in about 90 seconds, and the cost guides show typical ranges by state.

Yes — attached and detached ADUs are allowed on most single-family lots under Washington's updated middle-housing rules, with Bellevue's own size, height and setback limits applying. Our ADU rules by city guide explains how the state framework works, and we handle the zoning check, design and permitting in-house.
