Hello.
Looking to do a picture framed low level deck across two levels – one to be level with doors (Deck A) and one to be slightly lower (Deck B) that is level with the bottom edge of windows. Planning on just doing Deck A first. I don’t have any building experience but have been looking at other designs on here.
The space was previously paved and is between the house and a brick wall. The ramp will be removed and be replaced by a single step down between the two deck heights.
Plans for Deck A (red line)
- Area is 6700mm long and 4300mm wide
- Single layer substructure on posts
- There are a few little details around the edge of the space to work around and two drains; one that was in the middle of the paved area and one next to the bathroom wall
- 100x100 cypress posts with bitumen rubber paint
- Bearers and decking boards in the direction of the width
- From here I am not certain but thinking:
- 140x45 H3 bearers – stumps approx. 1333mm apart with 150mm counter for each side due to existing concrete near walls on either side;
- 140x45 or 90x45 H3 joists on joist hangers – spaced 450mm; saw a span table on another post about 1400mm for 140x45 or 900mm for 90x45
- Depending on which joist will also influence the distance between bearers?
- Any advise would be appreciated - will try to get a diagram up too
- Thanks
