How to Build a Bay Window Seat With Storage Step 3: Plywood Cover

Cover the face of the structure with plywood, Wainscot, or drywall. If you plan to paint the face of your Bay Windwow Seat with Storage the same color as the trim in the room, use plywood or Wainscot and fasten the wood to the structure with 2” wood screws. If you want to paint the face of the seating area the same color of the room walls, cover the front of the structure with drywall and attach the drywall to the 2×4 supports using standard drywall screws.

Measure the width of the covered wall and cut a length of baseboard to this dimension plus its own thickness. So if your measurement is 72” wide and the baseboard is 1” thick, cut a section of baseboard 73” long. Cope the ends of the new baseboard to mate the existing baseboard.

Measure the perimeter of the upper supports item 1, item 2, and item 3. Carefully cut the ¾” plywood to these dimensions and shape but extend it 1-1/4” beyond the front vertical face. Your plywood trapezoid should follow the extreme outer shape of the 2×4 supports plus 1-1/4 inches. If you remember your shapes from your days in grade-school, the cut plywood should be an Isosceles Trapezoid, and you thought you would never use this term when you graduated from school!!!

Hinged Sitting Area

Attach a ¾” x 1-1/2” (item 6) board to the underside of the ¾” plywood at the outer-edge using 1-1/2” wood screws. The plywood and stiffener (item 6) will extend beyond and in front of the front wall. Cut the Trapezoid per the sketch below to create a hinged area. Install hinges to the underside of the plywood. Place the plywood on top of the frame and fasten the out perimeter to the support frame using 2” woodscrews.
