Firstly, a hello to all, I've lurked for a long time and joined today in the hope of some advice regarding a deck I'm planning to build.
SWMBO and I are currently about to start building a house - they should poor the slab in the next week or so, and the intention is to build a deck after handover.
The plan is for the deck to stretch from the back of the house, to the back fence of the block (approx 4.6m) and from one side of the block to the other (approx 12.6m)
My thoughts are to use H4 TP 90mmx90mm joists on stirrups with H3 TP 90mmx45mm joists supported on joist hangers between bearers.
as the deck will be very close to ground level - possibly even touching the ground in some places, i also intend to coat all timber in black paint on H4 treatment stuff. (probably not the technical name )
actual decking will be mixed Aus hardwoods.
I'm also looking to source the bearers in 5.4m lengths and cut them down to size so they are a continuous beam with no joins
post assembly, all joints between bearers and joists to be coated with more paint on h4 treatment.
I've drawn the whole lot up in sketchup and attached some screenshots with dimensions in the hope that those more knowledgeable than me might point out any glaring mistakes or, hopefully, tell me that the design will work.
Red parts are the 90x90 bearers and the three different coloured blues are different length 90x45 joists
Joist and bearer layout (the two square holes are to go round trees)
If anybody needs anymore info let me know.
I await you critiques (be gentle)
