New Construction in Sammamish
New construction buyers in Sammamish are usually looking for one thing: a home that doesn't need anything for the next decade, in a market where most of the housing stock is 20-30+ years old. The good news is there's real activity here — the bad news is available land has narrowed as the Plateau has built out, so the window on specific communities can close faster than buyers expect.
Where New Construction Is Happening
Parkside, near Sammamish Commons Park — built by Terrene Homes, featuring open-concept layouts and elevated finishes
Beaver Lake — newer construction from national builders including D.R. Horton, in one of the Plateau's established central neighborhoods
Breton — a smaller community of custom and semi-custom homes from established local builders, known for larger, more private lots
Trossachs and Sahalee also see periodic new construction and full renovations, though most of what's built there today tends to be custom, one-off builds rather than large planned communities.
What New Construction Actually Costs Here
New builds in Sammamish generally start in the high-$1M range and move well past $2M depending on lot size and finish level. Homes.com data showed roughly three dozen new-construction listings active at once as of mid-2026, with new Sammamish listings overall moving in under 30 days on average — faster than the resale market's mid-20s pace.Building Custom on a Lot You Already Own or Are Buying
Because so few large, buildable lots remain on the Plateau, some buyers choose to purchase an older home specifically for the land and either renovate extensively or tear down and rebuild. If you're considering this route:
Zoning Restrictions: Confirm current lot coverage limits with the City of Sammamish before you buy. Setback and impervious surface rules strictly dictate how large a footprint you can actually build.
HOA Guidelines: Check for strict architectural review requirements if the lot sits within a covered community. Certain neighborhoods enforce rigid exterior design guidelines for total teardowns or major renovations.
Permit Timelines: Budget realistically for extended schedules. Custom builds in this area routinely take significantly longer to clear municipal design review, environmental permitting, and active construction.
What to Know Before You Buy New
Financing Incentives: Builder incentives are real, but read the fine print. Many developers are offering below-market rates for the first few years, which can be a genuine financial advantage or a trap depending on your long-term hold timeline.
Independent Diligence: New construction doesn't mean no due diligence. Inspect a brand-new home just as thoroughly as a resale property; craftsmanship and warranty quality vary wildly from builder to builder.
Lot Availability: Act decisively when a specific community catches your eye. Because available land on the Plateau is tightly restricted, smaller custom developments sell out at a fast pace.
