Ellery ADU Studio in Wisconsin

Ellery ADU Studio in Wisconsin

Ellery ADU Studio designs, permits, and builds accessory dwelling units across Wisconsin under one contract and one written price. We were founded in 2015, the year California’s ADU permitting shift began, which means our entire company has only ever built ADUs. Wisconsin homeowners get the same thing our first client got: a permit set treated as the core product, drawings and construction from a single team, and a documented photo record of every visit. For those outside the state, Ellery ADU Studio in Wyoming - ADU offers the same integrated approach. No designer pointing at the builder. No builder blaming the designer. The price is written before anyone starts, per Haven Standard Clause 1.

Why Wisconsin Homeowners Choose Ellery ADU Studio

Most ADU projects stall in the gap between the architect who drew the plans and the contractor who builds them. One says the drawings were incomplete. The other says the changes were out of scope. The homeowner pays for the gap. Ellery ADU Studio removes the gap by contract: the drawings, the permit set, and the construction are one company, one written price, one accountable party. We’ve designed, permitted, and built more than 900 ADUs since 2015, and every single one started with a written price before any work began. Our sister location, Ellery ADU Studio in Alabama - ADU, follows the same pricing commitment. That’s not a policy we mention when it’s convenient. It’s Haven Standard Clause 1, and it applies to every project in Wisconsin, whether the scope is a new detached ADU, a garage conversion, a junior ADU, or site prep and utilities.

We also coordinate prefab and modular systems within the same contract. If your Wisconsin property is better suited to an Abodu, Cover, Dvele, Plant Prefab, or Boxabl unit than to stick-built framing, we specify it, permit it, and manage the installation without handing you off to a separate vendor. When we finish, you receive a documented photo record showing what was built against the permitted drawings. If something isn’t done right, the 365-Day Done Right Promise says we make it right, in writing, before the project starts. And if you already have an estimate from another firm, we’ll give you a free second opinion on it.

Backed by the Haven Family

Ellery Adu Studio sales & service operates as an independently owned and operated member of the Haven family. Haven was formed in 1998 to buy good home-service companies and keep them good by standardizing the one thing customers actually lose sleep over: not knowing. Price, person, and evidence are made known before you have to trust anyone. Every Ellery project in Wisconsin is held to the five Haven Standard clauses, with the Done Right Promise attached. A haven is somewhere nothing bad is going to happen to you. That’s the condition we’re selling in Wisconsin.
