Hi everyone, looking after some help with decking. We have a split level home with an outdoot section that was I believe used sit a spa. The tiling looked horrible, was raised in some parts, so I wanted to rip it up curious to see what was underneath so I could look at options. It appears to be big sections of sandstone, which they tiled over. The section is boxed in with brickwork. The high side of the brickword does seem very sturdy, though does look rough
This would be a great spot for a deck. Area is approx 3.5 x 3.5 with a view to extend out further in the future.
My questions/comments:
- Where do I start? I know the area to deck, how do I work out the bearers/joists required, and relevant sizes?
- I'm not a complete noob, as I have built retaining walls, fences etc many times, and would love to give this a go
- Any considerations I need to take into account because of the sandstone? ie for footings? It varies in depth from 300mm to 600 or so. Can I use stirrups for bearers?
- Does the deck need to be attached to the house? As you can see from the pic, there is a section of the house, but that wall is not flat all the way across (its like a render/textured paint)

I've read a heap of the low level deck posts here, which have been awesome.
Thanks all 🙂
