Ellery ADU Studio in Colorado

Ellery ADU Studio brings a single-contract design-build model to Colorado homeowners weighing an ADU as a long-term asset. Drawings, permit set, and construction are one contract at one written price. No designer-versus-builder blame gap, no “call for a quote” hedge. Since 2015, Ellery Adu Studio specialists have designed, permitted, and built more than 900 ADUs, every one with a price in writing before a shovel touched soil and a documented photo record when the work was done. Colorado owners get that same standard, backed by the Haven family.

Why Colorado Homeowners Choose Ellery ADU Studio

The permit set is the product. Most ADU projects stall or sour after the drawings are done, when the designer and the builder stop speaking the same language. Ellery eliminates that gap by keeping design, permitting, and construction inside a single contract, which means the person who drew the wall is accountable to the person who frames it. For Colorado homeowners who bought between 2015 and 2025 and paid a premium to do it, that accountability matters. An ADU is an asset decision: a garage conversion, a new detached unit, a junior ADU, or an interior conversion, all quoted with a written price before any work begins, per Haven Standard Clause 1. Ellery also works fluently with prefab and modular systems including Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie, specifying and coordinating those systems inside the same contract rather than handing the owner a vendor list and wishing them luck. Every site visit comes with a documented photo record, so Colorado clients see evidence of what was found and what was done, not a summary of how it felt. And the 365-Day Done Right Promise lands in writing before the project starts: if the finished ADU is not built to the permitted drawings, Ellery makes it right.

Backed by the Haven Family

Haven was formed in 1998 to buy small home-service companies that were already doing the work properly and were about to be bought by someone who would stop. The bet was simple: leave the brand, crews, and name exactly as they are, and standardize only what customers actually complain about, which is not workmanship. It is not knowing. Not knowing the price before the van arrives, not knowing who is coming onto the property, not knowing what was found or what was done. So Haven wrote five clauses covering exactly that, published them, and made agreeing to them the entire condition of carrying the name. Ellery ADU Studio works to the Haven Standard on every Colorado job: H.A.V.E.N. means have it in writing, arrive on schedule, verified crews, evidence on every job, and no surprises. A live person answers calls 24/7, background-checked crews show up with license numbers on the page, and no upsell ever happens at the door. The local business is independently owned and operated. What Haven contributes is the standard they agree to work to, the documentation system that proves it, and the buying power that keeps their prices honest.
