Home cinema - garage conversion?
Discussion
Just one of those crazy ideas that float round inside my head from time to time....
What would it cost to convert an attached single garage into a insulated room fit for use as a home cinema/music listening room?
I'm pressuming a second inner wall skin, heat and sound insulation, plastering, false ceiling, insulated raised floor (on joists above existing concrete floor), then wiring and electrics and decoration.
As for kit, well I have enough to be going on with, so I'm not wishing to factor this in for now, although inevitably I would wish to upgrade at some time.

There are quite a few garage conversions on AVForums (look in the members gallery section). The only issue you'll have is that you're limited by width in a single garage so you can't go too huge on the screen size, though as you can't sit that far away from it then it compensates anyway. The guy I bought some of my equipment from has a single garage conversion which works quite well. I was tempted to convert mine, but it's detached from the house, so would be cold in winter and I'd have nowhere to keep my 'toy'.
Appologies if you're not talking about a projector setup, in which case it's a 'Telly room, garage conversion'.

We part converted our garage to create a utility room (I much prefer your idea though!). Didn't cost that much in the grand scheme of things (can't recall exactly) but we had to dig up the floor, embed some insulation, and then concrete on top which was messy and added to the cost.
It's now the warmest room in our house by a mile...

You will need planning permission for a change of use IIRC.
Hi, I do loads of these, no planning required ( unless listed or in a conservation area.)All the work can be done on a building notice. ( eg you do need building control sign off)
As for insulation, it is the normal to use 100mm celotex/kngspan on floor, walls and ceiling.
Floor can be floating eg no concrete.
Walls and ceiling usually counter battened and plasterboarded.
Garage door removed and 90% of the time BC are happy for a ground beam for the new wall so no need to dig footings.
Cost wise, last one I did, (as a music room for a musician) was a bit unusual as he had French doors instead of a new wall and window, ( so he could get the piano in. Total start to finish decorated and carpet was just over £7k.

That's great, thanks Alex.
Looking at the space it is a bit small for a home cinema, but the extra room would be really useful. We have a little one on the way, so we're losing our office to turn it into the nursery. Reckon the garage conversion could be a great new office/hobby room/ den!
It's a very long garage, so was thinking of putting the new wall part way along, leaving an area at the front, inside the doors, for racking out for storage.
