We have a detached double garage which was built approximately 5-6 years
ago.

I am considering converting half of it to house recording equipment for
my son and was wondering what the implications of doing this are.

The garage wall is a single brick width with two separate up-and-over
doors separated by a brick pier. The roof is made from trussed rafters
and there is one (small) window to the side. There is power to the
garage and the floor is concrete.

My thoughts are to divide the garage down the middle with stud partition
wall, remove the up-and-over door and brick up the opening. This is
where the entrance would be. Inside would be dry lined and possibly a
wooden floor would be built over the existing concrete one.

Would this sort of conversion require planning or building regs. Are
there any major gaffs in the way I am thinking? We don't actually put
cars in the garage, it is currently housing all the usual clutter that
inhabits most garages!

Any thoughts on this would be gratefully received.

Regards

Martin
