The last structure at the Darwin Martin House Complex by Frank Lloyd Wright in Buffalo, NY is the Caretaker’s Cottage. This you would think would be a tiny shack, but no, it was a large two story building in a similar but stucco style. The inside was similar to the other buildings at the Darwin House and it had wood floors and beautiful doors, light fixtures and moldings. Even the glass in the windows was Art Glass. Notice there is no obvious front door on this street view. The door openings are hidden on the side.
A view of the rear of the Caretaker’s Cottage with its added on rear room done in the exact same style including the Art Glass, copper gutters and roofing.
