I am laying a floor in the loft to support a cloakroom (wc and basin). Presently the loft is boarded for storage. The span of the house is 18' (5.4m). There is one 7'' X 2.5'' joist running the span (18') of the house which has sagged about 4cm in the centre. I want to run 6''X2'' joists from the 7X2.5 joist to the wall of the house, which is a distance of 2.25m (7.5'). Would it be a good idea to first brace the 7X2.5'' joist with timber using glue and bolts?
Or should I run joists the 18' width of the house? If I did that I would have to make up the lengths in situ by bolting two shorter lengths together. Thanks for any opinions on the matter.
