About

Mercer Island occupies the middle of Lake Washington in King County, an island community stretching from the North End through Town Center to the South End near Luther Burbank Park. General construction here ranges from luxury custom builds and large view-driven additions to substantial remodels on the island’s landscaped, often sloping lots. With Bellevue and Seattle just across the bridges, homeowners expect polished results, and building on an island means every delivery, excavation, and pour is planned around limited access routes and shoreline-sensitive parcels.

We provide Mercer Island homeowners full general contracting, from ground-up custom homes near the Lake Washington shoreline to whole-house remodels and additions across the North and South Ends. Island logistics shape material staging and crew scheduling, and our subcontractor network reaches easily from the surrounding Eastside and Seattle.

Site Conditions

Mercer Island lots frequently fall away toward the Lake Washington shoreline, making retaining walls, slope stabilization, and foundation drainage central concerns. Glacial till, seasonal groundwater, and heavy tree cover affect excavation and footings, while the constant marine damp keeps moisture management a priority on every build.

Seasonal Considerations

Because the island shares the Puget Sound wet-season pattern, we target the drier months for excavation, concrete, and framing, protecting open foundations from saturating rain. Summer is ideal for site work, decks, and exterior envelope, and the wetter half of the year suits interior remodel phases and finish work that keep projects moving regardless of weather.

Common Project Types

Typical Mercer Island work includes custom home construction, teardown-and-rebuild projects, primary-suite and lakeside-view additions, ADU and detached garage builds, deck and outdoor-living structures, plus foundation, retaining wall, and drainage upgrades on the island’s sloped parcels.

Property Styles

The island is dominated by established single-family homes on landscaped lots, many with lake or mountain views and mid-century-to-modern architecture, so remodels balance updated open layouts with the structural and view-preserving priorities owners value.

Local Materials & Plants

On Mercer Island we lean on moisture-tolerant assemblies, cedar and warm wood accents, fiber-cement and stone cladding, and durable metal or composite roofs suited to lakeside exposure. Site planning routinely works around mature conifers, madrones, and layered garden plantings that give island properties their privacy and character.

Planning Your Project

Mercer Island projects run through King County-area review, shoreline awareness near Lake Washington, and standard permitting for custom and additive work, so we handle surveys, engineering, and approvals up front. Planning emphasizes island access logistics, staged inspections, and tight coordination among designers, engineers, and trades.
