Ellery ADU Studio in Michigan
Ellery ADU Studio brings a different model of accessory dwelling unit work to Michigan: one contract, one written price, one accountable team from the first sketch to the final photo. Since 2015, Ellery Adu Studio specialists have designed, permitted, and built more than 900 ADUs, every one quoted in writing before any work started and documented with a photo record when the work was complete. Michigan homeowners who build with Ellery get the full weight of the Haven family behind that promise: the price is fixed on paper, the crews are licensed and background-checked, and the permit set is treated as the core product, not an afterthought.
Why Michigan Homeowners Choose Ellery ADU Studio
The typical ADU project fails at the handoff between designer and builder. The drawings say one thing, the framing says another, and the homeowner is left standing between two parties pointing at each other. Ellery ADU Studio was built to remove that gap entirely. The drawings, the permit set, and the construction are a single contract at a single written price, so there is no designer-versus-builder blame game available to anyone. That matters in Michigan, where attic conversions, garage conversions, and basement-level Junior ADUs introduce structural questions that a design-only firm on one side and a build-only contractor on the other simply cannot resolve together, unlike the Ellery ADU Studio in Minnesota - ADU approach. Ellery carries the permit set through planning review, coordinates prefab and modular systems from manufacturers like Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie, and puts background-checked, uniformed crews on site whose license number appears on every page of this site, verified rather than claimed. If the finished ADU does not match the permitted drawings, the 365-Day Done Right Promise applies, in writing, before the project starts. Michigan clients also receive something unusual in this trade: a free second opinion on any written estimate already in hand, and a documented photo record on every visit, so they see what was found and what was done rather than reading a summary of how it felt.
Backed by the Haven Family
Haven was formed in 1998 to buy small home-service companies that were doing the work properly and about to be bought by someone who would stop. The bet was simple: leave the brand, the crews, and the name alone, and standardize only the one thing customers actually complain about, which is not workmanship. It is not knowing. Not knowing the price before the van arrives, who is coming into the house, what was found, or what was done. Ellery ADU Studio operates under the Haven Standard, five clauses published and binding: the price in writing before work starts, a real arrival window with a named technician, licensed and insured crews with the license number published, photographic evidence on every job, and no upsell at the door. A haven is somewhere nothing bad is going to happen to you. That is the condition Michigan homeowners are buying back when they sign with Ellery.
