“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!”

Work closely with our designers to bring your vision to life. We'll customize every aspect of your ADU project, ensuring it fits your lifestyle and property perfectly. From layout to finishes, your ADU will be uniquely yours and built to match Atlanta's architectural requirements for your neighborhood.

From laying the foundation (using methods that work in Georgia clay) to adding the final details, our ADU builders oversee every phase to ensure timely progress while maintaining quality. You'll know what's happening, when it's happening, and what it costs - no surprises.
