Ellery ADU Studio

Ellery ADU Studio

Ellery ADU Studio designs, permits, and builds accessory dwelling units under one roof and one contract. No separate designer handing off to a separate builder. No gap where responsibility disappears. Since 2015, the team has completed 900+ ADUs across California, with expansion now underway through Ellery ADU Studio in Alabama - ADU services, every one priced in writing before work began and documented with photos when work was complete. As part of the Haven family, Ellery operates under the Haven Standard: written price, verified crews, evidence on every job, and no surprises. What you see on paper is what gets built, and if it is not, Ellery makes it right.

What Ellery ADU Studio Is Known For

Ellery treats the permit set as the product, not paperwork that happens to be required. That is the difference you feel when the city asks a question and the answer already exists in the drawings. The studio has designed, permitted, and built more than 900 ADUs since 2015, the year California’s permitting climate changed and owners started looking for someone who could actually get a project through, a model now extending to Ellery ADU Studio in Alaska - ADU projects. Every one of those projects carried a written price before any work started, per Haven Standard Clause 1, and every one produced a documented photo record at completion. Ellery works across the full ADU spectrum: new detached units, garage conversions, junior ADUs, interior conversions, and the site prep and utility work underneath all of it. The team also specifies and coordinates prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie, all within the same single contract. If you already have a written estimate from another designer or builder, Ellery will give you a free second opinion on it, line by line. And the 365-Day Done Right Promise is in writing before the project starts: if the finished ADU is not built to the permitted drawings, Ellery makes it right.

Part of the Haven Family

Haven was formed in 1998 on a simple observation: good home-service companies were being bought by people who would strip what made them good. Haven took the opposite approach. Leave the name, the crews, and the craft alone. Standardize only what customers actually complain about: not knowing the price, the person, or the evidence. The Haven Standard is five clauses, published, and agreeing to them is the entire condition of carrying the name. Ellery ADU Studio is independently owned and operated, working to that standard on every project, backed by the documentation system that proves it and the buying power that keeps prices honest, with the same commitment now guiding Ellery ADU Studio in Arizona - ADU operations.
