Hi... new here.
I own a large village hall / place of worship. 10m x 17m space inside.
I want to build 2 rooms within the space (hall) using blocks so that it will be structural for 'walk on' storage above.... and maybe another floor in future. Rooms are for Control Room (mixing desk room) and Vocal booth.
I understand that I have to dig out and install footings for the blocks... and have plenty of common sense with build + have contact with experienced builders.
But.... do I need to apply for building regs?
If I do.... can I go ahead and start the job without regs app.?
What are precautions if I do?
I already have planning permission (change of use from place of worship to rec.studio)
