Measure plywood sheet to 4x6. This will be the floor of the hideaway structure.
Cut plywood sheet to 4x6 with circular saw.
Cut (4) 4 ft pieces and (2) 6 ft pieces for floor frame
Build out floor frame by attaching 2x4s with screws
Drive 3 inch wood screws into the 2x4s with drill.
Attach the 4x6 plywood sheet to the frame using the 3 inch wood screws
You'll build the wall of the hideaway in the same way - only it will be 4x4 instead of 4x6. Frame out using (4) 4 ft 2x4 then attach the 4x4 plywood sheet.
To create a window - cut out a rectangle using a circular saw. This window cut out was approximately 12x18 in.
Frame out the window using 1x2s.
Attach the frame using a brad nailer.
For the back - you'll need to cut a 6 ft plywood board to have an angled edge. To create the angle - measure two feet up on the left side of the 6 ft plywood board. From that point - take a straight edge and draw a line to the top of the right side of the board. Then, cut along that line with a circular saw.
We painted the pieces before assembling. To assemble - attach the three pieces together with 3 inch wood screws. We attached the bottom to the right side from the bottom and attached the back along the bottom and on the right edge.
Place velcro along the top to attach the canopy top. Also add velcro along the back angled edge.
To get the canopy to hang a little nicer - we added a single post using a 2x2 baluster and some angle fasteners. Then, added velcro to the post as well.
