Convert internal Garage.

[Nintendofan]

Hi, I'm looking at adding a stud and plasterboard wall to my internal garage on a 5 year old new build. The concrete floor is already insulated and only a few centimetres lower than the house and is separated by a wooden fire door, the garage internal is breeze block with cavity on the external wall and plastered on the internal walls. The ceiling is plater boarded and insulated as there's a bedroom above.

I would want the new room to be a 'warm' room with the remaining garage staying as it is. Would a standard wooden stud wall, plater boarded and insulated with rock wool keep the cold out and would I need a fire door in the new wall or could I use a standard external door and frame? I will be keeping the existing garage door as it is.

Would I need to adhere to and apply for building regs, and or planning permission. Thanks.

remaining garage staying as it is.

The "remaining garage" is presumably too small to fit a car in, right? I wonder what implications that has for the fire regulations. I guess you could still keep a motorbike full of petrol, or a jerry can, or something in there.

A house five years old will in all likelihood have had it's permitted development rights restricted, that is the right to carry out certain development without applying for planning permission. One of those restrictions is very likely to be garage conversions so you should check your deeds for what restrictions apply - you probably need planning permission, officially. That said what you're doing can't be seen from the outside so perhaps you'll get away it with it provided you don't upset the neighbours etc and they dob you in. Of course it's likely to come up when you come to sell.

It also requires Building Regulations approval, the partition and door would need to be 30mins @endecotp the regs applied to the garage when built would remain.
