Ellery ADU Studio in New Jersey

Ellery ADU Studio in New Jersey

Ellery Adu Studio specialists handle the entire ADU process under one contract across New Jersey: the drawings, the permit set, and the construction. No handoff from designer to builder, no finger-pointing when something doesn’t line up. Since 2015, we’ve designed, permitted, and built more than 900 ADUs, every one with a written price before any work started and a documented photo record when work was complete. New Jersey homeowners working with Ellery get a single point of accountability, which matters in a state where municipal permit reviews vary sharply from county to county and a sloppy drawing can stall a project for months.

Why New Jersey Homeowners Choose Ellery ADU Studio

Most ADU projects in New Jersey fail before the foundation is poured. The designer blames the builder, the builder blames the drawings, and the homeowner is stuck holding a stack of change orders. Ellery ADU Studio was built specifically to close that gap. We’re a design-build studio, not a contractor coordinating subcontractors: one contract, one written price, one team responsible for everything from the first site measure to the final inspection. That means when we quote a detached ADU, a garage conversion, a junior ADU, or site prep and utilities, the number on the page is the number you pay. Haven Standard Clause 1 requires it: written price before any work starts, on every project, no exceptions. We also offer a free second opinion on any written estimate you already have in hand. Bring us a competitor’s number and we’ll tell you honestly whether it’s realistic, what’s missing from the scope, and where the change orders will hide. Beyond pricing, our crews are background-checked and uniformed, and their license number appears on every page where our name does. And because Ellery has specified and coordinated prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie, we can often shorten the construction timeline without sacrificing the permit quality that New Jersey towns actually care about.

Backed by the Haven Family

Ellery ADU Studio operates under the Haven Standard, five published clauses that every Haven company is held to. For New Jersey homeowners, that means the price in writing before work starts, a real arrival window with a named technician, licensed and background-checked crews, photographic evidence of what was found on every visit, and no upsell at the door. The 365-Day Done Right Promise applies to every Ellery ADU Studio in New Mexico - ADU project: if the finished ADU isn’t built to the permitted drawings, we make it right. In writing, before the project starts. That’s the whole point.
