Text description by

The Granny Pad, by Seattle-based Best Practice Architecture, is an innovative accessory dwelling unit (ADU) created from a converted backyard garage. Completed in 2018, the 571-square-foot project offers a solution for multigenerational living in cities with limited housing options, providing a safe, accessible, and private home for an aging family member.


The project was designed with both immediate and future needs in mind. To accommodate the decreased mobility of the elderly family member, the entire living area was designed on a single level. The layout flows seamlessly from the entry and kitchen to the bedroom and bathroom. To prevent the small space from feeling cramped, the design incorporates a number of strategies to increase the perception of volume. Exposed rafters emphasize the high ceilings, and strategically placed skylights and windows flood the


While the design is currently optimized for a single occupant, the architects considered its long-term potential. The lofted area above the bathroom, currently used for storage, could be converted into an office, a sleeping space, or a creative studio in the future. This adaptability future-proofs the investment and offers flexible housing options for the family.

The architects creatively worked with the site's natural six-foot slope, building the Granny Pad into the hill. This allowed for the inclusion of a lofted space and a private back deck connecting to the unit.


The Granny Pad is a thoughtful and functional conversion that makes the most of its small footprint.

The garage door was removed and the original garage structure now serves as the entry, kitchen, and sitting room. The floor plan places the private areas—the bedroom, bathroom, and laundry—at the rear of the unit.

A small, secluded deck and garden area provides a private outdoor retreat for the resident.
