This is my first post on this forum. I have tried to glean what I’d like to know from previous posts but it’s more a best practise recommendation I’m after. I hope this is in order with accepted forum protocol.
I've recently had a deck & pergola plan done and have 2 specific concerns. Have attached plans (+ draft material list fwiw).
Concern 1: Deck is 9.5m * 3.6m & there seems to be a lot of posts (21) and bearers (3 + 1 ledger) in this plan. Would it be preferable to increase the planned size of sub frame timber with the aim of decreasing the number of required posts & bearers?
Concern 2: Ledger on a brick veneer wall that runs from 20cm above ground on the low side to 1.6m above ground on the high side. The high side of the ledger has no vertical support underneath it. I’d read elsewhere (may have been an American forum) that this was not advised except on weatherboard houses.
I raised the 2nd concern with the guy who did my plans and the gist of the reply was …
“The practice of Dyna bolting a ledger beam to the brick wall for the use of supporting floor joists is an approved method by the Australian building commission and is the most used method”
His complete explanation seemed valid to me but I’d like to know if I am able to use ... say 1 ledger, 1 middle bearer and 1 side bearer if the load on the ledger would then exceed some recommended threshold of sorts?
I’d appreciate any advice on these two questions please.
