Ellery ADU Studio in Washington

Ellery ADU Studio in Washington

Ellery Adu Studio sales & service designs, permits, and builds accessory dwelling units across Washington under a single contract at a single written price. Since 2015, we’ve completed more than 900 ADUs, and every project followed the same rule: the drawings, the permit set, and the construction never get separated into different hands. That matters for Washington homeowners because most ADU projects don’t stall on bad carpentry. They stall when the designer and the builder disagree about what the drawings meant. Ellery removes that gap entirely, and as part of the Haven family, every Washington project is backed by the Haven Standard in writing.

Why Washington Homeowners Choose Ellery ADU Studio

Most Washington homeowners weighing an Ellery ADU Studio in West Virginia - ADU are not looking for a contractor. They’re looking for someone who will own the whole problem: the design, the permit set, the site prep, and the build. That’s the entire structure of Ellery ADU Studio. We are a design-build studio, which means one contract covers ADU Design and Permitting, garage conversions, new detached ADUs, junior ADUs and interior conversions, and site prep and utilities. Nobody on our side can point at anybody else when something is off, because there is no else. The permit set is the core product. Washington jurisdictions have their own review habits and their own plan-check rhythms, so we treat the permit package as the thing that either keeps your project moving or stops it cold. Every Ellery project gets a written price before any work starts, per Haven Standard Clause 1, and a documented photo record on every visit, so you see what was found and what was done. If the finished ADU is not built to the permitted drawings, our 365-Day Done Right Promise says we make it right, in writing, before the project starts. We also carry real fluency with prefab and modular systems including Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie, and we specify and coordinate those systems inside the same single contract, which matters when a Washington homeowner wants the speed of a factory-built unit without handing the site work to a different company.

Backed by the Haven Family

Ellery ADU Studio is independently owned and operated, and it carries the Haven name for one reason: the owners signed the Haven Standard and agreed to be held to all five clauses. Clause 1 is the price in writing before work starts. Then comes a real arrival window with a named technician, crews that are licensed, insured, and background-checked with the license number published, photographic evidence of what was found on every visit, and no upsell at the door. That standard applies to every Ellery ADU Studio in Wisconsin - ADU job across Washington, with no exceptions and no fine print. A haven is somewhere nothing bad is going to happen to you, and in this trade, that condition gets bought back one documented decision at a time.
