This isn’t so much about a workshop build as a question about modifying my existing space.
My house is built on a slope so we have two storeys at the front but three at the back. Some 30 years’ ago, the area under our dining room was excavated and the floor lowered. Prior to that, the room in the basement varied in height from 6 ft. at the bottom side to 3 ft. at the top side. The work was all signed off by building control including having to underpin the wall at the back. However, at the time, nothing was ever done about the ceiling. There’s about 6 ft. 3 ins. headroom and there are just the joists and floorboards from the dining room above, all painted black some 50 years ago before we moved in. What I would like to do, after all these years, is put Celotex or similar between the joists before boarding between the joists with either plasterboard or MDF. I can’t afford to attach anything to the bottom of the joists in view of the restricted headroom.
The question is, does this sort of insulation work require building consent?
