How to Build a Window Seat Bench With Doors

Measure the area where you plan to install the window seat, as well as the cabinets. Cut 2-by-4 boards to form a frame that the cabinets will sit on top of, driving finishing nails where the boards meet.

Position the frame on the floor and drive wood screws at an angle through the bottom of the frame and into the floor. Arrange the cabinets on the wood frame, leaving the back corners of the seat blank if your bench curves like a “U.”

Open the cabinet doors to ensure the configuration does not stop their free movement. If the cabinets are too close together for the door hinges to work, cut strips of wood one inch wide and the same height as the cabinets, and position the wood strips between the cabinets. Drive wood screws through the inside bottom of the cabinets and into the wood frame you constructed.

Drive wood screws through the back panels of the cabinets and into the wall. Measure any empty spaces in the seat configuration, that are not taken up by cabinets. Cut 2-by-4 boards to the size of the empty spots, and attach them to the wall with wood screws. The top edge of the boards must be level with the tops of the cabinets.

Cut pieces of 3/4-inch-thick wood panels to fit on the top of the cabinets and the 2-by-4s you secured to the wall. Lay the panels on the seal and drive finishing nails into the cabinets and boards around the perimeter of the boards. Paint or stain the seat to match the design of the rest of the room.
