You can use the sketch here as an examples of dimensions taken by us and calculated for a window seat according to our bay window. Create your own sketch of the dimensions you take out in a similar manner and also draw a sketch of the seat you will make next to it.


  1. You will now build the frame, as show in the picture, according to the dimensions you have drawn out. Use the stud finder and the level to set the surrounding panels of the seat around the wall. With the wood screws. attach the rest of the frame. Mitering is not needed on the corners. Create the front wall frame keeping it parallel with the back wall. Cut the top and bottom piece with a 45 degree angle to match the wall. In the end, you will have four front panels at the front wall. You will add 2 x 4’s to the side walls and add bracing for the top. Use wood screws for attaching them.


  1. You may install each board at the front individually, or set a single face frame for the seat. Build it according to your style and choice, and paint it.


  1. Cover the front of the seat with the face frame. Use nails to attach it to the frame. If there are any holes, use wood putty and then caulk the seams using silicone.


  1. Now you will build the top of the seat. You will need four pieces of 3/4 inch plywood with a 1 1/2 inch strip of trim for the front edge.
