Popponesset Island

Mashpee, Cape Cod, MA

This newly built property presents two different but unified faces: From the street, it appears private, with the main house and detached carriage house defining a courtyard. At the rear, whose wings look like glass-enclosed porches, walls of windows and French doors suggest openness, connecting the house to its Popponesset Bay view.

This concept continues inside, with smaller, private rooms in the front of the first floor and one open space at the back. Though large, this great room feels intimate, thanks to its coffered ceiling and window placement. Above, three bedroom suites enjoy sweeping water views, as do a pair of spacious decks.
