Hear from homeowners who transformed their backyards with our ADU builds, from tiny homes to in-law suites. Our clients value the quality, craftsmanship, and clear process we provide.

“Cottage Smith has helped turn a deeply personal idea into something that feels truly possible. We’re exploring an in-law suite so we can keep our aging family close, and their team has shown so much care, understanding, and guidance throughout the process. Seeing their work and design options made us feel confident we’re creating more than just a space—we’re creating comfort, connection, and peace of mind for our family.”

Anne Hawkes

“My partner and I absolutely LOVE our new tiny house!! We initially thought we could build our own but we had a strict deadline. We researched tons of different tiny home companies and looked extensively online. Their price was the best around, the quality of the product is nothing short of amazing (thanks GOD we didn’t try to make our own!) and every detail is beautiful. We had approximately 6 million questions and he was so patient and responsive. If you’re going tiny, consider them!”

How It Works

From your first floor plan to final inspection, we handle each detail of your ADU project. Here’s how it works.

1. Property Evaluation

Schedule a consultation with our ADU builders. We'll walk your property, find the best spot for your ADU, and give you a clear estimate. We'll talk about what you want it for: rental income, more space for family, a home office, or a creative space.

2. Design Customization

You'll work with our designers on each part of your ADU, from layout to finishes. We'll make sure it fits your lifestyle, your property, and your neighborhood's style rules.

3. Permit Process

Permits in Atlanta can feel tricky, so we handle them for you. We manage zoning checks, paperwork, and inspections, and we work with your county's building department.

4. Efficient Construction

Once permits are approved, we start building. Our ADU builders oversee each phase, from the foundation, built for Georgia clay, to the final details. You'll always know the schedule, the cost, and what's next.

5. Final Walkthrough

When construction is done, we'll walk through your new ADU together. We'll check each detail so it's ready for you to enjoy.
