Whether you’ve earned your sea legs or are still a landlubber, this luxury boathouse — which is practically hanging over the Des Plaines River in Riverside, Illinois — provides the best of both worlds. On the market for $1.5 million, this 3-bedroom, 4-bathroom home incorporates views of the river below into nearly every room. While the structure does feature a three-car garage, homeowners might be more attracted to the fact that they can park their floating vehicles beneath the home in one of the two boat slips included.
