– Three pieces 2×4 lumber – 10 ft; two sheets 4×8 ½-inch plywood
– Hinges; wood screws; paint or stain;
– Saw; adjustable tool (to determine the angle of the sidewalls); paint brushes; stud finder;
– Sand paper; level; protective gear

How to Construct the Frame Work

– Cut the 2×4 lumber, to follow the perimeter of the window.
– Draw a chalk line just below the window. Make sure the chalk line is level.
– Using a stud finder, find out where the studs are and mark them on the wall.
– Set the 2×4 studs on the wall with wood screws. Make sure the top of the studs is in line with your chalk line. Set all three studs pieces following the bay window perimeter. You should install the studs at a height of 17 inches.
– Measure the distance between the floor and the bottom of your already installed frame.
– Cut 6 pieces of 2×4 and place them under the edges and joints of your angle wall frame.
