setting out joists

if they are first floor joists, then leave a 50mm gap.
this will allow room for the hanger* to sit on the outside wall. it will also allow easy access to the fixings even after the wall has been plastered.
it may be a useful space for the plumber too.

yes, i realize you are talking about the parallel wall, as you referred to a gap when setting out.
if you are using hangers on the opposite wall then this gap will allow room for the width of the actual hanger.

how are you dealing with the joist bearings?
