hi i am currently slowly building a 6060 x 4000 extension, brick @ block and would appreciate any help and advice. could any one help calculate the roof load.specified as - 50x170 C24 @ 400 centres 12mm ply on firrings to falls 115mm celotex 6mm external ply 3 layers felt also, whilst trying to be in keeping with existing building i would like to have full height doors and windows (to roof height) which therefore would leave me a span across the front of 6m with an 'opening' of 4m for glazing. i would like, if possible to span this with wood and joist hang off of it. what would be best to use for this? C24 bolted together? solid bean? flitch beam? i am trying to research as much as possible but finding answers hard to come by. any help is much appreciated.
