The term ‘granny flat’ comes from one of the popular uses of an ADU as a home for elderly or aging relatives. Other names for an ADU include granny unit, in-law suite, casita, garden cottage, and more.
But the ‘granny flat’ is not just limited to older relatives! This backyard space is ideal for many uses, serving as a guest house for visiting family and friends, or maybe even an at-home office for telecommuters. ADUs are versatile and designed to meet your needs.
Our Summit Series shed serves as the perfect granny flat or ADU and is fully customizable.

OTHER COSTS TO CONSIDER WHEN BUILDING AN ADU ARE:
Foundation
Our ADUs are built to stand on a poured concrete or self-supported joisted floor system. We can set you up with a ProBuilder who can provide an estimate for your site!
Shipping
Shipping costs are calculated in our 3D Design Center before you purchase. We ship to all 50 states and select locations in Canada.
Assembly
Do-It-Yourself assembly is the most cost-effective option, but if building an ADU (even a prefab one) isn’t your forte, we have trusted assembly partners.
