This wooden sun deck we built in Westville Durban was designed to try to maximise outdoor space. The house we built it at had very little outdoor space as it was situated on a steep plot. You can see from the pics that before we built the wooden sun deck, the garden had only a small area of about 1m around the pool on the front side of the garden. There was then a steep concrete staircase down the side of the house going to the back garden. The back garden was however not very usable as it was far from any entrance to the house. So the idea here was to build a wooden sun deck that extended from the slasto of the pool area to meet the far side of the house. It was about 48m² in total floor area and was surrounded by a wooden balustrade in a picket design. We left the existing concrete stair case in place and built the wooden sun deck so that one could use this existing stair case. Hence the U Shaped deck.
We also had to split the wooden sun deck into two levels as the area by the pool was a little lower than the area where it met the existing concrete deck. So we had a split level deck with a small step up of about 180mm. 180mm is always a good step height or riser height.
The posts beneath had also been lined up so as to avoid being placed in the middle of the stair case. Even though the outer posts were some distance from the bottom of the stairs, if we had placed them where they would normally have gone (i.e. equal distances from either end) then it would have spoilt the line of sight as one was walking down the stairs. So they were shifted slightly left and right to miss the line of the stairs.
We also had a garden shed beneath the front edge of the deck so we had to build around that which had had a new roof built on it and waterproofed. When building over waterproofed structures one cannot drill through the torch on as it will results in leaks beneath. You need to then build on either side of it or use thicker beams and joists to be able to span them further apart.
In the pics on this article you can also see the horse shoes we used to support the beams on the walls. Instead of dropping posts to ground you can simply attach the beam to the wall by cutting a horse shoe using the same timber as the beams. The bottoms are always cut to 45° for both neatness and to avoid having sharp corners jutting out. This also applies to the ends of main beams.
We treated our cut ends with Permaseal, an approved end sealer used to stop rot or insect damage to cut ends of CCA treated timber. This was necessary in order for us to activate the 50 year guarantee that the supplier provides on the CCA Treated pine substructure. There are a few articles on this blog that go into detail about this and what is required in order to activate your 50 year guarantee.
