Decks are a wonderful solution for families who are seeking to add a bit more space to their outdoor garden areas.
A finished deck will add years of enjoyment, and can solve the problem of a sloping lot or poor access.

Mark out the perimeter of the decking area using string and pegs. Check that the corners are at a 90 degree angle using a builders square.
Mark out a rectangle or square deck with pegs and strings. Check the corners are at a 90-degree angle using a builder’s square. Mow any grass very short.
Lay down a weed supressing membrane over the area to be decked, overlapping joints.
Lay a weed-proof membrane, and overlap joints by 18 inches. Roll it back when setting the outer posts, but cut through it for internal supports.
Dig holes for decking corner posts deep and fill in 3 inches with gravel.
You will need a post in each corner and the rest spaced in a grid pattern, one every 4 feet. Dig holes 15 inches deep, and fill 3 inches deep with gravel.
Install decking corner posts with post mix concrete and water. Use a bubble level to check for vertical. Let it set before continuing.
Fill the hole with water to dampen the gravel, and allow to drain. Insert the post, and pour in post-mix concrete, using a level to check if it is vertical. Leave it to set.
Cut and install edging boards. Drill holes and attach through boards into corner posts using nuts and bolts.
Cut edging boards to length, and drill bolt holes through them and the posts. Attach one end of the first edging board to a post using nuts and bolts.
Level first board and fix in place with nuts and bolts. Trim the ends flush, and repeat on the other three sides.
Level the first board, and fix it in place with nuts and bolts. Trim the ends flush. Repeat these steps until all three sides are fixed, then tighten the bolts firmly.
Attach internal joists between the edging boards across the shortest span, spacing them evenly apart. Check for level along the way.
Pre-drill holes, and use nails to fix internal joists between the edging boards across the shortest span, spacing them 16 inches apart. Make sure they are all level.
Use long nails to secure decking joists at regular intervals.
To hold joists rigid, cut short lengths of lumber and insert them between the joists at 4 feet intervals. Secure them using long nails or metal brackets.
Predrill decking boards, and attach them to each joist using decking nails or countersunk screws.
Cut a decking board to length. Pre-drill holes in the board, then attach it to each joist using two corrosion-resistant decking nails or countersunk screws.
Attach the decking boards, spacing them a quarter of an inch apart to allow for expansion.
Cut remaining boards to size, and attach them to the deck, making any joints above the joists. Space the boards 1/4-inch apart, using spacers, to allow for expansion.
