On Cape Cod, a Bauhaus-style house gets a sibling guesthouse on a dune facing a salt marsh and a mile-long stone breakwater. And while Provincetown is known for its progressive thinking, it still has little in the way of contemporary architecture. So the team knew it was creating something unique and special, using finishes similar to the original house–gray, taupe-y stone, and dark wood.

Different types, widths, and colors of wood create some modern rustic chic in the bathroom. The angular tub looks like it could have been made in the future and transported back to the present time.
