Converting a garage
Discussion
I'm converting a garage at the moment for a customer. No planning issues as its residential. Building regs involved though and different regions will have different requirements as they interpret the regs differently.
This is what I'm doing.
Damp proof membrane to floor, build false floor with 4" x 2" joists, infill with 100mm Celotex, overlay with T&G chipboard flooring.
Build stud walls all round 3" x 2" leaving 75mm cavity to be filled with rockwool.
Build false ceiling with 3" x 2" joists, insulate with rockwool.
First fix plumbing and electrics
Board and skim
Second fix plumbing and electrics
Second fix joinery.
Quite a nice straight forward little project. If you liase with building control before the project starts they are usually very helpful. Well worth a call and a chat to see what their requirements will be to ensure all runs smoothly.

I had my garage / store room / junky area converted about 8 months ago. Finished article is a 13m x 7m games room.
Work involved included building a wall with windows at one end and bashing down a wall at the other end to form 2 windows and patio doors. Internally there was a fair bit of knocking down bits of non supporting walls and fitting out the interior. Effectively this was timber framing and kingspan insulation stuff, plasterboarding, plastering, electrical supply stuff. Not sure whether being in Scotland alters the paperwork required but all that was needed was a building warrant application, although the garage / room is attached to the main house and not a seperate building. Quotes for having the work done varied by 200% which was a shocker!!

I rung a local number to come and trash some stuff in my garden, old furniture carpet etc. A year earlier I was charged £60 for two guys spending 10 mins loading and taking to tip on the back of a van.
New guy comes, sees the TVR, has a glance at the stuff to trash and tells me £130. Cash.
I tell him thanks, but no thanks, politely. He tells me it costs at the tip etc etc, I tell him no thanks. He gets back in truck, I go inside.
2 minutes later, the doorbell rings again and he is now happy to accept £75! He still gets sent packing on the principle of the original wallet-raping quote. Got the old guy back in again for £60.
blatant thread hijack, but I dont really see point in making a new thread for this.
I want to convert my garage, which is basically, well, a basic garage, to a workshop for my bike/s so I dont have to get my wallet raped for 50 pound an hour.
what would I need to do to make sure the walls dont get damp through and it need a new roof.
what would be the best way/stuff to put a new roof on it? it has to be fairly sturdy

its attached to the house and brick build.
I think its single brick but not 100%.
it is a slight pitch roof. other than that, I dont really know
OK, assuming you just want to improve the quality of your work environment and not actually turn it into a habitable space you can do as little or as much as you want without any intervention from building control.I think its single brick but not 100%.

Single brick garages often suffer from penetrating damp - driving rain will hit the brick and soak through to the inside of the building. There is no cavity to stop it.
To do the job properly it would mean building the inner skin and leaving a cavity but this would be overkill in this instance plus taking up valuable space.
I would recommend covering the walls with a vapour barrier, attaching batons to the walls, infil with some polystyrene insulation and then boarding with plasterboard. All stuff you can do yourself if you are remotely handy with a few tools. Use boards with a tapered edge, tape the joints and fill and sand and then there is no need to skim.
With the ceiling (I am assuming if you look up you see timber joists with ply or OSB above which is then covered by felt) again, fill with insulation (rockwool like in your loft) and then board, tape and sand. The area above the insulation will need ventilation to stop condensation so a couple of airbricks or just above the insulation will be required.
Re-roofing, well you could have it re-felted which is a job for the pros or use this:

Give me a shout if I have missed anything or you want to know anything else.
Oh, and an insulated garage door will help to.
