Custom Homes in Three Lakes & Machias

Cost-plus custom home building for the Three Lakes, Machias, and greater Snohomish County area.

Tucked between Snohomish and Monroe, the Three Lakes and Machias area takes its name from Panther, Flowing, and Storm Lakes — a rural, heavily forested stretch of Snohomish County where lots run large and homes sit spaced well apart from their neighbors. The area’s housing reflects decades of building: early bungalows and farmhouses alongside newer custom construction on multi-acre lots, with waterfront and equestrian properties at the high end.

Real demand, real numbers

Recent sales in the area tell the real story better than averages do. One custom home on nearly 5 acres — built in 2022 — sold in May 2026, going from listing at $2.15 million to a closed sale of $2.05 million within a week. Another, on over 6 acres, sold above $2 million as well. This is an area where serious buyers are actively competing for well-built homes on real land, and where custom valuations often run higher than public housing data alone would suggest.

Building in Three Lakes & Machias

Most of this area sits in unincorporated Snohomish County, permitted through the County’s Planning and Development Services rather than a city building department. Larger acreage lots here often rely on private wells and septic systems rather than municipal utilities — one of many site-specific factors that shape a project’s design and budget from day one.

The Three Lakes chain

Storm Lake drains into Flowing Lake, which feeds Panther Lake. Storm Lake covers 76 acres, Flowing Lake 132.5 and Panther Lake 49. Gas-powered motors are prohibited on Storm and Panther, which keeps them quiet, and Flowing Lake has the County’s park and swimming beach at Leckie’s Beach on its north end.

Building on a lakefront lot

All three lakes are over 20 acres, which makes them shorelines of the state under Washington’s Shoreline Management Act. Anything within 200 feet of the ordinary high water mark falls under Snohomish County’s Shoreline Management Program. A single-family home built for its owner is generally exempt from a shoreline substantial development permit, but it still has to meet the program’s buffer and vegetation standards, and the County confirms the exemption in writing before it issues the building permit. Those standards decide where the house can sit on the lot, so we work them out before design starts, not after.

Wells and water

Away from the lakes, most acreage here runs on private wells. The area drains to the Snohomish River, where the County limits a new permit-exempt well to 950 gallons per day on an annual average, reducible to 350 in a drought. It also requires a water-use covenant recorded on the title and stormwater handled on site with low-impact development methods. None of that is unusual, but it shapes irrigation and landscape plans and belongs in the budget from the first conversation.

Forested lots

Washington currently has no wildfire building code. The state rescinded it in April 2026 while new hazard maps are drawn. On a heavily wooded lot, how far to go on fire-hardening is a design decision we make with you early, while it costs the least to build in.

How we build

Every Lockie Homes project runs on the same Feasibility and Construction Agreement (FCA) process, regardless of where it’s built: open-book cost-plus pricing, a Bid-Backed Budget built from real subcontractor bids, and a dedicated project manager keeping you informed at every stage.
