Build An Awesome ADU With Our Pre-Designed Plans

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.

We’ve recently released our own pre-designed ADU plans for San Diego residents. These designs are now available for homeowners + property investors in the greater Los Angeles area.

Elevate Your Lifestyle with Our Los Angeles ADU Plans

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.

Key Benefits of Building with Our Pre-Designed ADU Plans in Los Angeles

Interested in saving time, money, and stress while building an ADU? Our pre-designed ADU plans are expertly developed to help you build an ADU with modern + minimalist design, without the hassle. While these plans are pre-designed, they’re anything but cookie-cutter and include many customization options available to make the space your own.

A Quick Start Blueprint to Save You Time + Money

When you begin an architectural project with a pre-designed option, you gain high-end designs at an affordable price point. These plans exist as the framework of your build and allow our architects to breeze through the design process, a stage that is typically one of the longest parts of an ADU build.

With a pre-designed plan, construction on your project will begin weeks before the traditional process would allow.

Our team looks forward to helping you customize our pre-designed ADU plans for Los Angeles homes. We'll help you achieve elevated fixtures, functional features, and livable outdoor space while tailoring the design details to fit your personal style, project goals, and the dimension of your lot. Plus, because these plans have been designed to fit small lots, as narrow as 25’ wide, they incorporate common codes and regulations for ADUs. This will lessen the chance of running into any delays or unexpected fees as we begin to bring your dream project to life.

These customization options can elevate the look and feel of your ADU with modern form following function.
