Build An Amazing Detached ADU in San Diego With Our Plans

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.

How Our Pre-Approved ADU Plans Will Fast Track Your Build

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.

Key Features of Our
Pre-Approved ADU Plans

Building an ADU is an exciting process that requires a great deal of research, with many architectural options and details to consider. We'll help you integrate high-end design, custom features, and elevated fixtures into our pre-approved plans while staying within your budget and timeline.

And, because these plans were created with the same modern + minimalist style as our modular ADU designs, you'll achieve extra design value at a fraction of the price.

Our detached ADU plans provide our clients with a customizable foundation that will speed up the process. We'll tailor the designs to fit the specifications of your lot's orientation and dimensions.

Customization Options as Necessary

Our modern architecture studio understands the importance of creating a space that reflects not only your lifestyle but also your personal style.

As accessory dwelling units have become more popular in Southern California, we’ve incorporated several customization options to make your ADU stand out as a neighborhood favorite.

Depending on the dimensions or orientation of your lot, these plans will give you the option to save space with smaller rooms, convert your dwelling into a two-story duplex, or create outdoor spaces with balconies or patios to enjoy the San Diego sun without increasing your lot's footprint.

Our team of expert architects has also mastered the city's building regulations and design process to increase the functionality + sustainability of your ADU regardless of its size and layout.

Save Time, Money, and Stress

Our pre-approved plans were designed to help you build an elevated ADU that showcases elevated modern + minimalist design without the expensive price tag and project delays.

By using one of our pre-designed ADU plans as the framework of your project, you can save upwards of $20k from our typical design + engineering fees.

And, when you purchase our detached ADU plans directly from us, you’ll be able to start construction on your project right away with an expedited schedule.

Without drafting your ADU from scratch, we can take 3-4 months off of our typical design timeline.

Because these plans have been pre-approved by the San Diego building department, you’ll be able to speed through the permitting phase with confidence and begin your build in no time.
