Experience the Ten Seventy Advantage with our Pre-Approved ADU Plans

Our pre-approved ADU plans embody the core principles of modern and minimalist design, helping you create a high-end ADU that enhances living in San Diego (or any Californian city). From vaulted ceilings to solar-oriented roofs, our designs cleverly utilize space and promote efficient living.

Experience Expansive Living in a Compact Space

It's a common misconception that smaller spaces can feel cramped and restrictive. Our architectural prowess challenges this notion head-on.

By meticulously planning every inch, we ensure that our designs not only maximize your yard space but also provide a spacious feel within. Key features like vaulted ceilings don't just add a touch of grandeur; they transform the ambiance of the living room and kitchen areas.

The result? Homes that may have a smaller footprint, but breathe with a sense of expansiveness, making every moment inside feel liberated and vast.

Blur the Boundaries with Indoor-Outdoor Living

One of the profound joys of living in picturesque locales is the seamless transition between indoor spaces and the beauty of nature outside.

Our ADU plans are tailored to encapsulate this experience. Bedrooms that flow effortlessly into private exterior patios bring the tranquility of nature right to your doorstep.

Whether it's a peaceful Sunday morning coffee ritual, a space for meditation, or a quiet corner to decompress after a hectic day, this seamless integration enhances the quality of everyday life, offering a refreshing retreat without leaving home.

Embrace Sustainable Living with Solar-Oriented Roof

The future of home design is intrinsically tied to sustainable practices, and our approach to ADU plans is no different. While modern aesthetics remain paramount, functionality, especially in the realm of energy efficiency, takes center stage.

Our innovative roof designs not only provide a sleek finish to the ADU but are also crafted to ensure optimal solar panel placement. Regardless of your lot's orientation, these designs harness the sun's power most efficiently.

It's our way of intertwining beauty with responsibility, ensuring your modern ADU isn't just a design statement but also a nod to a greener future.
