Ellery ADU Studio in New York

Ellery ADU Studio in New York

Ellery ADU Studio designs, permits, and builds accessory dwelling units across New York under a single contract and a single written price. Since 2015, we’ve delivered 900+ ADUs, each with a permit set as the core product and a documented photo record when the work was complete. New York homeowners working with us don’t manage two parties who can point at each other when something goes off. They hold one agreement, one team, and one number that was written down before anyone picked up a tool. That’s the Ellery Adu Studio specialists model, and it’s backed by the full weight of the Haven family.

Why New York Homeowners Choose Ellery ADU Studio

Most ADU projects stall at the gap between the designer’s drawings and the builder’s interpretation. Ellery closes that gap by making the drawings, the permit set, and the construction one scope of work with one accountable party. We’re a design-build studio, not a contractor coordinating outside designers, and that distinction matters when a New York building department asks for revisions. The person who drew the wall section is the same company building it.

Every project begins with a written price before any work starts. That’s Haven Standard Clause 1, and there’s no exception for ADUs. You’ll also receive a free second opinion on any written estimate you already have in hand, because we’d rather you compare our numbers against reality than against a sales pitch. Our crews are background-checked and uniformed, and their license information appears on every page. When work is underway, every visit includes a documented photo record: what was found, what was done, what it looked like before and after. And the 365-Day Done Right Promise applies in writing before the project begins: if the finished ADU isn’t built to the permitted drawings, we make it right. Ellery also specifies and coordinates prefab and modular systems, including Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie, within the same contract, so a panelized build never becomes a finger-pointing exercise between a factory and a contractor.

Backed by the Haven Family

Haven has spent the years since 1998 doing one thing: putting the price, the person, and the evidence in front of the customer before they have to trust anyone. Ellery ADU Studio keeps its name, its crews, and its local accountability across New York, and agrees to all five Haven Standard clauses, with other Ellery ADU Studio in North Carolina - ADU locations operating under the same terms. Written price first. Named tech with a real window. Licensed, insured, background-checked crews with the license published. Photo evidence on every visit. No upsell at the door. A haven, by definition, is somewhere nothing bad is going to happen to you. That’s the condition every New York homeowner gets when they hire Ellery.
