Exterior Adu Design Photos and Ideas

The suburban backyard garage in Hertfordshire, England, that architect Olli Andrew of Hyper converted into a work studio is wrapped in charred larch wood pieces that give the impression of scales and foster biodiversity, providing a place for insects to nestle.

The steel structure is suspended two feet above the roof of the existing bungalow, supported by four steel columns, one of which screens utility lines running from the Perch to the house below.
Joanna and Steve Vernetti have lived in their 1917 bungalow in Hancock Park for over 20 years. As their family increased in size, they needed more space—so they initially thought about adding another floor. After California passed the regulation in 2020, they called up their good friend (and former neighbor) David Thompson. <span style="font-family: Theinhardt, -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Oxygen-Sans, Ubuntu, Cantarell, &quot;Helvetica Neue&quot;, sans-serif;">Thompson, a founding principal of Assembledge+, had recently participated in a Los Angeles Magazine project to imagine solutions for those who lack housing in the city. Their notion was for public agencies to subsidize building ADUs in backyards along alleyways, dovetailing with existing alley revitalization initiatives</span><span style="font-family: Theinhardt, -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Oxygen-Sans, Ubuntu, Cantarell, &quot;Helvetica Neue&quot;, sans-serif;">.</span>
Best Practice added a new roof but kept the existing siding. A fresh coat of paint helps the casita pop, and a new window opening next to the entrance frames a new kitchenette inside.
The garden-level living area of the ADU faces perpendicular to the existing house, offering a measure of privacy to the detached building.

The bright orange tone of the front door matches the color of the accent wall in the living room, connecting the exterior and the interior of the ADU.
Recurring diagonal motifs in the shared spaces, such as the semi-open entryway—formerly the garage—are intended to create overlapping zones on the lot, the architect says.

Architectural designer Ben Warwas converted a compact, two-car garage behind a 1,440-square-foot front house into a 400-square-foot accessory dwelling unit in Los Angeles.
“The parapet makes the building look quite a bit bigger than it is and it creates an idea of mystery – or discovery” says Ben.
Staircases surround the house, which is accessed from both the north and south facades.
Wedged with precision between the existing garage and pool, the narrow new structure is only 13 feet wide.
The “maintenance-optional” Shou Sugi Ban siding is something the homeowners can enjoy from both the ADU and the main house. “The burnt wood exteriors face our house as we look out at the ADU, and we love seeing how the light reflects on it throughout the day,” they say.
