Planning a small decking project mainly for foot traffic outside laundry door to clothes line.. Overall size is 1.95mwidth and 3.0m length, but need to work around 600x600 hot water unit (HWU) towards the end of the deck.
Intend to use ledger attached to side of the house (up to 2.4m length) and also along the back of the garage (1.95m width)
Having studied both the DIY video and expert advice on low lying deck; need reasurrance/advice that I am on the right track in:
1. Need bearers across the 1.95m width attaching to the wall ledger on one side; and use 2 of 90x90posts with a span split evenly across the 1.95m (adjusted for the size of the 2 posts; and size of the wall ledger)? I take it if it is only single span, I would need to use a much larger bearer which would create a problem with the gap from ground to bottom of bearer. Without digging, the ground is 180 from the garage door.
2. Run 4 sets of bearers along the 3.0m length of the deck; First 3 bearers placed approx 0.8m apart (for the 2.4m length before adjustment for the HW unit); with the last bearer placed 0.6m.
My questions are:
What size treated pine should I use for the 1.95m bearers? Can I use 120x70; or 120 x90 or something larger?)
What size treated pine for the ledger, and what bolts and size should I use to attach to the wall?
Can i use 90x45 for floor joists placed within the bearers using joist hangers?
Can you advise me what should be the minimum gap from the base of the bearer from the ground?
Look forward to your advice and any special tips. Much appreciated.
