Garage Conversion
Discussion
Morning All
My house, currently rented but firm intention to purchase next summer, has a double garage attached to the house, with a door from the hallway through to garage 1.
The two garages are not used as garages, although both doors are still in place. A stud wall has been built between the two, with the furthest garage door blocked off by a stud wall. The nearest garage has been semi converted into a utility room, but still has the door visible from the inside, i.e. no stud wall infront of it.
Once the purchase has gone through next year, I intend to convert these properly, the furthest into a boys room (pool table, darts, heating etc) and the nearest into a utility, downstairs shower room).
In the meanwhile, the LL has given verbal permission to treat the place as our own, so I want to do something to the nearest garage door to insulate it for this winter. Can someone please let me know what to do - I am thinking line the door with some waterproof sheet, then a stud wall packed with insulation. The door is bolted closed. Should be reasonably cheap just in case the purchase goes tits up next year.
As for planning, all houses in the cul-de-sac have double garages adjoining the house, and most have at leat one converted properly, with window instead of garage door. Some have both garages done so I anticipate no issues with planning. The drive has space for three cars, and there is space to the other side of the house for a garage to be built should i want to later.
Thoughts are greatly appreciated, and many thanks in advance.

Stud Wall packed with celotex/kingspan insulation, should insulate roof/ceiling as well. I'd also consider insulating the floor 50+mm celotex then flooring chipboard. Position the stud wall behind the door, far enough back so that you can brick up easily (with cavity) at a later date.
I have a timber garage block and just made a room at the end, using this technique, seems to work well.

Thanks David. Any suggestion for waterproofing the door?I have a timber garage block and just made a room at the end, using this technique, seems to work well.

I forgot to mention the garage has a pitched roof massively insulated already. I like the suggestion about the floor.
Start with the floor.
Bitumastic DPM over the floor. (tar like material) this prevents any oil thats on the garage floor being "seeped" up.
100x 50mm bearers with 100m Celotex between then your flooring on top.
Garage door, go cheap on this as you will be knocking it back down next year eh?
100x50mm studs with 100mm Celotex between then a plasterboard finish. Don't bother plastering as you will be reskimming next year eh?
Sounds like the ceiling is fine.
Thats if I've understood you correctly.
As a foot note when you do go down the Building Regs route on a Garage Conversion I always for my clients send a copy of the drawings to the Planning Dept asking them to confirm in writing that no Planning Permission is required!
That way when you sell there are no questions to be asked as its all in writing!!!!

I assume the celotex does not act as a damp proof membrane, what do you suggest I use for this? I assume i will need one.....
