Insulating a garage

Hi all

I'm planning on converting my adjoining double garage into a store/utility/games room over winter. Does anyone know of any building regs that might apply that I should be aware of? The garage doors are going to remain in place, and we're installing a personnel door on one side wall.

Any hints greatly appreciated.
Cheers

All regs apply. It's tempting to think it being just a store regs might not apply but that's not how it works. Just insulating a room and boarding it out makes it potentially habitable and BCO will then treat it as habitable and then all regs apply. As a BCO said to me recently; if it looks like a duck it is a duck - even if it's not a duck! That's if they know about it of course.
