The standard tables only go to 2700mm.
I have been thinking of building an "Exempt structure" ie: a Sleepout in the back yard and i am keen on the idea of maximising the use of the ground area.
Local council say that irrespective of the ground area rule/exemption I need a permit to build two story but there are no restrictions on having a mezzanine bed.
This being the case I have been thinking of taller walls but I cannot find any tables for the timber sizes needed to go to the height I want and for the steep roof pitch needed to make a mezzanine bed platform work best.
Totally off top of my head i was thinking that the walls need to be about 3200 high with the bed platform sitting 2550 above the floor and I am assuming 140mm timbers as the mezzanine beams but if I can use 90mm even better.
Exempt building is still 10m<2 so any combination of L*W to give that, my first thought was 3500 X 2855 and that has to be external.
90*45 is available locally to 3600 easily, can I use this timber size to that height ? noggined at 1350mm centres of course.
Total novice sort of question but those are probably the easiest to answer, I hope!
