Built-In Window Seat

A window seat with storage underneath turns dead space into the most photographed feature in your house. Two IKEA Kallax shelves ($70 each) laid on their sides, a plywood top, foam padding, and upholstery fabric create a built-in that looks custom for under $300. The more ambitious version uses 3/4" plywood, face frames, and a hinged top for blanket storage. Either way, add throw pillows, a reading lamp, and you've created the cozy nook that sells houses. Every listing with a window seat gets more saves on Zillow.
