Planning
The key to a successful deck is in the planning. Avoid very wet areas completely and if the deck is in a shady area be prepared to treat and clean the wood annually. Draw your deck to scale on paper as accurately as you can, remember it's the deck boarding that governs the size of the deck. You should also bear in mind that any deck over 300mm off the ground will require planning permission.
Corner Posts
When digging the holes for your corner posts be sure to look out for any cables or pipes as you go. Once the soil is removed you should be left with a 300mm x 300mm square to a depth of 700mm for each post. Make sure you add a section of concrete block to each hole before adding in the post and Postcrete.
Outer Frame
If your deck is on a slope, start with corner where the deck is highest off the ground and mark on the post where the highest part of the frame will be. To ensure rain water runs off your deck, and away from the house, allow for a slight fall in the level of the deck frame by factoring in a fall of 2mm for every metre.
Centre post and Support Joists
Your support joists should run in the same direction as your deck boards. Sandwich the centre post between two support joists before securing with Postcrete. Trim your post by using a setsquare and a handsaw making sure you treat the cut ends as you go. When laying your landscape fabric it's best to overlap the fabric to ensure it covers all of the area under your deck.
Steps
Your steps should be supported on solid and level ground. When building your stairs you will also need to make sure they are flush with both the top and side of your frame. When securing your deck boards to the steps, always secure the front faces of the steps first.
Deck Boards
When securing deck boards we'd recommend drilling all fixing points with a 2mm bit to prevent them from splitting, also, if you countersink all drilled fixing points you will get a smoother finish. Keep spaces even between adjacent boards by using a spacer from an off cut of timber (we'd recommend a gap of 5-8mm to allow the timber to expand and contract).
Fascia Boards
Start by attaching all the boards that do not need to be cut down, with 64mm screws. If you are adding an angled board because the decking is being built on a slope you will need to add packers to the deck frame. Remember to also leave a gap of at least 5mm between the board and the ground as you do not want it touching the ground at any point.

Great video series, very informative and easy to follow. Wish my missus was as handy as the lady doing the job!
nice video
What a great video !
excellent video tutorial. :-)
Aren't you suppose to use nails on joist hangers for better shear strength?
what are the dimensions of this decking area? thanks for great video. ah I have just watched again. 3000mm by 3000mm.
On that foundation can build a house,it not necessary to be that strong for a deck
Wondering how much is the cost? . Seems alot of work for such a small area
É bom pelo
Wickes you need to make your mind up as 1 video says put face board up flush to deck board yet then this 1 days put underneath deck board lol
Your strangling the hammer
The grooves in the timber should be faced down, this prevents build up for water and stops the timber from rotting prematurely.
Nice looking deck though except for this.
uk?
milimiters?
since when :o!
