We are trying to create a nice deck area at the bottom of our garden to enjoy the evenings.
The dimensions are as follows:
4.8M length , Deckboards are 27mm x 145mm 3.6M wide, Front to Back Boards running left to right, 4.8M length.
The garden has a slight slope from front to back, no more than 3" or 4" thats with a 3.6m length on the front edge straight on the ground and the 3" at the rear by the rear fence.
Its pretty level from left to right, I had thought it was more of a slope from front to back so I originally thought about 47mm x 150mm however can I get away with 47mm x 100mm instead?
What I am wondering is whats the best way of supporting the joists? Do I need posts or can I use slabs etc?
dig out and lay concrete pads for the posts, fix the decking together and prop it till its level then attach the posts to the decking this will give you a solid base
