Ten Seventy Architecture combines a love of modern architecture, state-of-the-art technology, and a proprietary process to help our clients build Accessory Dwelling Units in Southern California. With over a decade as a leading ADU firm, our expert architects have mastered the ins and outs of the design + build process to bring your dream project to life.
Accessory Dwelling Units (also known as granny flats, in-law suites, companion units, and guest houses) have become popular projects in Southern California for homeowners and property investors alike. ADUs provide additional living space for family, friends, or tenants, expanding the livable square footage on a given lot. These residences can be built as part of an existing or soon-to-built home, or detached from the main home as a separate structure altogether.
When you work with Ten Seventy Architecture, our team of experienced architects will walk you through every option available for your ADU project. We've been at the forefront of accessory dwelling unit development for over a decade, staying up-to-date with the latest advancements and regulations. Now, we've used this expertise to offer pre-designed ADU plans for Los Angeles homes. These designs are based off of our self-funded project in San Diego, the Prince House ADU.
