Ten Seventy Architecture combines a love of modern architecture, a proven process, and the latest technology to help our clients overcome the challenges of building an accessory dwelling unit (ADU) in Southern California. With over a decade of experience, our architects navigate complex city codes to expand your space with elevated design.
Our newly released detached ADU plans make the process to get there easier and more efficient than ever. These plans are pre-approved and expert-developed.
Detached ADUs (accessory dwelling units) are independent residential units located on the same lot as a stand-alone house, providing homeowners with space between their primary residence and an additional residence that can be occupied or rented.
These types of units are great solutions for those interested in maximizing their living space or investing for rental opportunities. Detached ADUs can add significant value to your property by expanding livable space within your lot, generating rental income, or providing a home for a relative.
If you’re interested in building a sleek + functional ADU, you’ve come to the right place. Ten Seventy Architecture has extensive experience developing accessory dwelling units in and around San Diego. In recent years we’ve even funded + built our own ADU, the Prince House.
Through this project, we created a universal design that has been pre-approved and can be customized to fit the size of your lot. We've also incorporated many personalization options to ensure your future ADU reflects your architectural style and goals.
