I'm doing a self build extension and am about to install the floor joists. There to be installed on timber to brick hangers. I know the centres need to be 450mm but can anyone help with the distance of the first joist from the wall to start the spacing?
Pictures to follow on progress if your interested.

Drawing is from the architect but this has been a balls up from the off! Damp incorrect, floor slab incorrect, insulation incorrect, block type incorrect..... the list goes on! Joists are off the shelf 200x47x3100mm. Your right about the hangers setting it off about 50mm ish.
Will the 450mm centres cause any issues over 400mm? Also I understand I need a restraint strap, what length should this be and what spacing? None of this detail is shown on the drawings.
