Property is Victorian chapel, solid brick walls with suspended timber floor with void open to ground. Damp course bridged by high ground levels and signs that the joists are gone – floor dropped whilst walls still plumb.
The floor boards are lovely but with no access point will have to risk them in lifting if going to deal with joists. Also looking to add internal walls and a mezzanine floor so would benefit from something stronger under these.
So if floor coming up what are the best options for either restoring with extra support for new load bearing, add insulation etc or replace with a different type of floor and use rescued floor boards as floor cover at least in the main spaces?
And how much would I need to budget?
