The clients for an existing home in Seattle approached Best Practice Architecture with a need to make space for an aging family member, but the home on-site was already filled to the brim. The firm's answer was to expand the existing detached garage into a gracious and airy living suite. The architects worked with the natural, six-foot slope of the site and built the Granny Pad into the hill to gain the needed interior height. The volume on the right is the original garage footprint, which now houses a kitchen and sitting room. The added volume on the left hosts the bedroom, as well as a bathroom beneath the loft space.

Klopf Architecture's modest 72-square-foot addition at the front of the home blends in with the original structure while giving the owners a greater sense of openness in the master and hall bathrooms. Inside, the re-imagined great room now features dining space.
