Ellery ADU Studio in South Carolina

Ellery ADU Studio in South Carolina

Our Ellery Adu Studio services include designing, permitting, and building accessory dwelling units across South Carolina under a single contract and a single written price. Since 2015, our work has covered garage conversions, new detached ADUs, junior ADUs, and interior conversions, with 900+ projects completed to date. Every South Carolina client receives the same thing: a permit set treated as the core deliverable, a documented photo record of the work, and a 365-Day Done Right Promise in writing before the first board is cut. No designer-versus-builder finger pointing, because there is no separate designer and builder to point.

Why South Carolina Homeowners Choose Ellery ADU Studio

Most ADU projects go sideways at the handoff. The designer delivers drawings, the builder finds problems the drawings did not anticipate, and the homeowner stands in the middle holding two contracts and a change order. Ellery was founded in 2015 to close that gap. The drawings, the permit set, and the construction are one contract, quoted with a written price before any work starts. That is Haven Standard Clause 1, and the words “call for a quote” do not appear anywhere on our site.

South Carolina homeowners researching an ADU as a long-term rental asset or aging-in-place solution tend to ask the same three questions: what will it cost, what will the county require, and who actually shows up. We answer the first with a written number before mobilization. We answer the second with a permit set that is treated as the product, not the paperwork. We answer the third with background-checked, uniformed crews whose license number is published on every page. We also coordinate prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie within the same single contract, which can shorten timelines in municipalities where stick-built site work faces longer inspection queues.

If you already have a written estimate from another builder, we will provide a free second opinion on it.

Backed by the Haven Family

Haven was formed in 1998 to buy and build home-service companies willing to sign five published clauses: written price before work, a real arrival window with a named technician, verified crews with published license numbers, photographic evidence on every job, and no upsell at the door. Ellery ADU Studio is independently owned and operated and held to all five. If the finished ADU is not built to the permitted drawings, Ellery makes it right, in writing, before the project starts. That is the 365-Day Done Right Promise, and it applies to every project we take on across South Carolina and through Ellery ADU Studio in Tennessee - ADU locations.
