Hi guys,
Looking for some advice,
Building an extension and just getting to first floor level.
Because i want to match up the new and old floor levels up, i need to decide what joist sizes to use.
The SE has specified 7x2 c16 at 400 centres.
This would be fine one side, as i intend to bolt a big bit of timber to the old wall and and use joist hangers.
But because the other side is on an angle, i was going to rest the joists on the blocks.
However a 7x2 joist doesnt fit in with brick gauge. So can i pack the bottom of the joists with more timber to get the right height. (personally i think this sounds a bit crap, and not likely to pass building control)
or
do i pack it out with slate, is 2 inches of slate a lot to make up.
or do i just get 9x2 joists and sit them straight on the blocks?
if i use 9x2 can i increase the centres?
Span ranges from 2.7 m to 3.5m
Your advice as always is greatly appreciated..
Thanks
