There is a town at the end of Martha's Vineyard. The road narrows, the houses thin, and the light changes. This is Aquinnah — westernmost town on the island, six square miles of clay cliffs, a lighthouse, and one of the smallest year-round populations on the Vineyard. Compound-scale offerings almost never come to market here.19 Locust Lane is one of them. Nearly seventeen acres, sited high above Vineyard Sound with open water views to the Elizabeth Islands and beyond. A custom modern Dutch Colonial main residence and a separate guest house, both built in 2005. Cedar shake. Stone walls.Inside: over six thousand square feet of living space — wide-plank floors, an open-plan dining room, a great room with cathedral ceiling, cedar trusses, and a floor-to-ceiling stone fireplace. Aquinnah is the part of the Vineyard that has kept its character. This is the place that lets you stay there.
