Ellery ADU Studio in Indiana
Ellery ADU Studio brings Indiana homeowners a single-contract design-build model: the drawings, the permit set, and the construction are one agreement at one written price. Since 2015, we’ve designed, permitted, and built more than 900 ADUs, every one with a written price before work started and a documented photo record when work was complete. As a Haven family company, Ellery works under five published clauses that Indiana customers can hold us to, in writing, before anyone lifts a hammer.
Why Indiana Homeowners Choose Ellery ADU Studio
Most ADU projects stall at the handoff between the designer and the builder. The designer blames the builder for the framing; the builder blames the designer for the drawings. You own the argument. Ellery removes that handoff entirely because the permit set and the construction are the same contract, the same team, and the same written price. That matters in Indiana, where local jurisdictions set their own ADU rules and a permit set that misses a zoning condition can sit on a desk for months. We quote a flat price before any work begins, per Haven Standard Clause 1, and that price does not change once the scope is set. Every project includes a documented photo record, so Indiana clients see what was found and what was done at each stage, not a summary of how it felt. We also offer a free second opinion on any written estimate you already have in hand, including estimates from Ellery Adu Studio specialists in other markets. If it’s not done right, the 365-Day Done Right Promise says we make it right, in writing, before the project starts.
Backed by the Haven Family

Haven was formed in 1998 to buy good home-service companies and hold them to a standard, not strip them for parts. The Haven Standard is five clauses: a written price before work starts, a real arrival window with a named technician, licensed and background-checked crews with the license number published, photographic evidence on every job, and no upsell at the door. Every Ellery ADU Studio project across Indiana operates under all five, with the license number on the page and a live person answering calls 24/7.
