I have to build a floor in a loft. At first this will provide a platform for some roof timber repairs to be

At present, there is a lath and plaster ceiling, with rather wimpy-looking ceiling joists, so not the most

stable platform to work on. It’s in pretty good condition (as a ceiling, not a floor) so I’d like to keep it



2x8 joists is unusually large for loft storage. Almost all old joists are quite able to handle storage. So I wonder if you've fully and correctly evaluated the situation, ie what the current joist dimensions are (all 3).

Just going by the standard joist span tables for moderately loaded floors. Of courser a lighter joist would be cheaper/easier/more desirable. On the other hand, I'd rather not have the whole thing collapse!
