The idea

How it lives

One long porch shelters a compact block of bedrooms, baths and laundry. The roof is a true saltbox: the ridge sits five feet north of center, so the living room and kitchen rise into a tall space under the steep side. A 457 sq ft open loft sits over the middle of the plan and looks down into the living room.

  • A real saltbox

    An 8:12 roof over the porch side and a steep 16:12 roof behind, with the ridge five feet off center.

  • An open loft

    457 sq ft of loft, all of it with at least 7 ft of headroom, over the middle of the plan: a lounge and desk, not a bedroom.

  • Bedrooms down

    Both bedrooms, two baths, the laundry and a pantry are on the main floor, off one wide gallery.

  • A porch the length of the house

    A 44-foot covered porch runs the whole front, on five posts.
