How to Build a Wall-to-Wall Window Seat
This multipurpose built-in is perfect on a stair landing
Building a wall-to-wall seat with the back and sides concealed means only the front needs a finished face.
Start by securing 2x6 hanging strips horizontally to the studs along the three walls.
For the center support, toenail a 2x6 joist to the middle of the boards secured to the side walls.
For the seat's front, frame a small knee wall out of 2x4s, leaving a void in the center for the book cubby.
Top the platform with ¾-inch plywood, and cap its front edge with a molding strip.
Build the book cubby out of more ¾-inch plywood, and recess it in the knee wall.
Finish off the seat's front with beadboard cladding and baseboard molding along its bottom edge.
