Need advice insulating garage

Need advice insulating my garage

I had a stud wall built where the garage door was + had the roof part insulate
Last winter: brrrrr! It was freeezing!

OK... OK... so there still remains one large brick (5.5m long) wall and a single glazed window and door - around which there is brick
+ There's a concrete floor that is colder than the north pole!

1. Large brick wall - what should I do?
Insulated plasterboards? That's expensive from the prices I've seen
Build another stud wall in front of it?

2. Single glazed window + door - can I leave this?
I don't fancy going to the cost of adding a double glazed window - or do I not have any choice?

3. 2. Single glazed window + door - the bricks above and below the window - how do I insulate that part??

4. Concrete floor - put down wooden planks and then put laminate or carpet over it? (This is what someone suggested)
Good idea? Bad idea?

Any advice for the above would be great
Right now... it's still OK... I can work there wearing a jumper
But when it gets colder... impossible to work there!

Thanks

hmm, to be honest the whole thing is a bad idea.

either rebuild the stud wall, and replace the window and doors or get a powerful heater?

I expect most of the cold will be coming from the garage door?

It seems to me like you want a warm comfortable room but still want a full wallet.

You either want to do it right or not at all in my opinion because otherwise the cold will find a way to get you.
