Details are sparse, but the location is unbeatable: positioned just beside the 16th greens at Royal Troon Golf Club in Troon, South Ayrshire, Scotland, the host of the 2024 Open Championship. Blackrock House, which has just one neighbor, was built, alongside its match, before the golf course ever existed — and stayed put as the development was put into motion, making it the only house in the world (well, one of two, technically) on a major golf course. The driveway snakes through the course, while the garden butts against the 17th fairway. The bedroom windows get grander views of several greens. And every eight or so years, you play host to one of golf’s biggest tournaments.
