Remodeling Mercer Island Homes, With the View and the Long Term in Mind
Kitchen, Bath & Outdoor Living Remodeling
Home remodeling on Mercer Island means working with some of the best mid-century architecture on the Eastside, and it deserves a remodeler who can tell the difference between dated and worth keeping. The 1950s–70s moderns here have wonderful bones — clean lines, big glass, a real relationship with the site — usually wrapped around a kitchen and bath that stopped working decades ago.
The island also has a high number of homeowners who have been in the same house for twenty or thirty years and have no intention of leaving. That shapes a lot of our home remodeling work on Mercer Island: a main-floor primary suite, a curbless shower that looks like a design choice rather than a medical one, wider doorways, better lighting. Done well, aging in place is simply good design that happens to last longer than you do.
Island properties tend to be steeper, tighter, and more scrutinized than a typical lot, so the planning phase carries more weight here than almost anywhere we work

Our clients walk in apprehensive and walk out as advocates because the experience matched the expectation.
