Before heading over to the job site, we visit the 1827 African Meeting House, a former school, church, and meeting house used by Nantucket's black population until the 1920's and now the object of a restoration effort. Contractor Bruce Killen builds ... (more)a new door frame for the restored Victorian double doors, which he and the crew hang. Then we go to Switzerland to see one man's solution to the high cost of building and real estate there: high-quality factory-built houses.
