A simple shed addition to a 1940s Cape Cod house borrows the straightforward language of its counterpart and elevates it with sophisticated architectural details. The addition connects expanded family and entertaining spaces to the landscape and introduces a new master bedroom suite to the first floor. The centrally located kitchen aligns with an outdoor kitchenette and ipe-slatted deck, extending the entertaining space across the landscape. Flanking the kitchen, the new family room and screened porch’s angular, vaulted ceilings playfully engage the space. Traditional building components and finishes are thoughtfully placed on unexpected surfaces and in unconventional patterns and quantities. Inside, sentimental objects are interlaced with new architectural details. Together, the array of selected interior finishes weaves the old and new into a visually intricate, lived-in space.
