Ellery ADU Studio in Missouri
Ellery ADU Studio designs, permits, and builds accessory dwelling units across Missouri under a single contract and a single written price. Since 2015, our Ellery Adu Studio services have delivered more than 900 ADUs, garage conversions, and junior units, each one backed by a documented permit set and a photo record of the finished work. Missouri homeowners working with Ellery get the same guarantee Haven has published since 1998: the price in writing before anyone starts, the crew verified before they arrive, and evidence of what was built when the job is done.
Why Missouri Homeowners Choose Ellery ADU Studio
Most Ellery ADU Studio in Montana - ADU projects stall in the gap between the designer who drew the plans and the builder who has to make them work. Ellery removes that gap entirely. The drawings, the permit set, and the construction are one contract, so when a Missouri homeowner asks why a wall is two inches off the drawing, there is no designer pointing at a builder and no builder pointing back. There is just us, and we fix it. That’s the 365-Day Done Right Promise, and it’s in writing before the first board is cut. We also publish our prices instead of hiding behind a request form. Every Ellery project in Missouri is quoted with a written price before any work begins, per Haven Standard Clause 1. If you already have an estimate from another studio or contractor, bring it in and we’ll give you a free second opinion. And when our crews show up, they’re background-checked, uniformed, and their license number is on the page, not just claimed. We work regularly with prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie, coordinating the factory-built components within the same single contract, so the schedule and the scope never drift.
Backed by the Haven Family

Haven was formed in 1998 to buy good home-service companies and leave them better, not bigger. The bargain was simple: keep the name, keep the crews, and agree to five published clauses covering price, arrival windows, verified licensing, photographic evidence, and no door upsell. Ellery ADU Studio in Nebraska - ADU operates under that same Haven Standard on every project across Missouri, with a written warranty and a documented photo record on every visit, so you always know what was found and what was done.
