An 85 square foot first floor addition and 515 square foot second floor addition transform this early 20th century in-town Ann Arbor from a 3 bedroom / 2 bath to a 5 bedroom / 3 bath home. The floating second floor addition, which includes a parents’ bedroom suite and a guest bedroom, hovers over the rear driveway to provide a covered carport and still allow access to the shared detached garage. The small first floor addition replaces the original rear covered entry porch and provides a conditioned mudroom and additional space for a remodeled kitchen. The contemporary addition relates to the original home in scale and form, while clearly distinguishing itself as a 21st update to the in-town narrow lot vernacular of the neighborhood.
