Hatch House sits hidden behind sandy hills and trees overlooking the bay, a 15 minute drive down a potholed, single-lane road surrounded by miles of Cape Cod’s National Seashore. Designed by modernist architect Jack Hall in 1961, it’s constructed of cubes connected with outdoor wood decks. It was built for Robert (an editor) and Ruth (a painter) Hatch as a summer cottage and was occupied by their family until 2008 when ownership was reverted to the National Parks Service. Since 2013, it has been operated as an artist and scholar residency by Cape Cod Modern House Trust, and you can actually stay there to help support their work.
