Step 8: Construct the angled perimeter.

Locate and position the outside row of Dek-Block® piers according to the dimensions on the plan. Just like before, level and position the 2"x6" support board. Both ends of the support board will have a standard 90 degree cut. Using the dimensions found on the plan, cut the two angled side boards. Each end of the boards will have 45 degree cuts. For this board the dimensions found on the plan are to the LONG side of the board. Secure the angled boards to the support boards with three 2 1/2" deck screws at each connection. Before securing the support board to the outside posts, ensure the side is square. You can do this by measuring the diagonal distance from opposite corners. If needed adjust the outside support board until the diagonal distance between opposite corners is EQUAL. After the deck is square, attach the 2"x6" support board to the 4"x4" posts using two 2 1/2" deck screws at an angle (toe-screw) from each side of the support board.
