To create a built-in window seat, first measure the selected area and purchase cabinets that equal those dimensions and molding to match. Take the original molding from the wall where the cabinets will be placed. Build a frame to support the cabinets using 2-inch by 4-inch lumber. To add height to the window seat, opt for 2-inch by 6-inch boards. The frame should match the width of the sitting area and have a central support beam.Continue Reading
The depth of the frame should be 2 to 3 inches less than the window seat. Place the frame flush with the wall under the window, and attach it with screws.
Take the doors off the cabinets, and use a C-clamp to clamp them together, side by side. Attach the cabinet with screws and center them on the frame. Use wood screws to secure the cabinet to the base.
Measure the space between the cabinets and the wall on either side from the top of the cabinets to the top of the base molding. Cut two filler pieces according to the dimensions and attach them to the sides of the cabinets. Measure the toe kick area, and cut a piece of trim to fit. Attach it with nails. Insert the shelves into the cabinets.
Take the top board off of the cabinet, and place panel adhesive around the edges. Firmly push the seat into place. Reattach the cabinet doors, and use caulk and trim to fill in any gaps between the seat and the wall.Learn more about Seating
