Estimate

We have a double garage attached to our house. It's two story. We'd love to convert the upstairs part into two rooms and a bathroom as it's just wasted space at the moment.

From my investigations I think it would need to be slabbed, insultated, divided into two rooms and a bathroom, wired and piped.

It's 700 square feet and structurally sound. I've attached a picture. That third mini floor is been removed.

I'd love to convert it now but realistically I don't want to start the process because I know we can't afford it at the moment. However, just to curb my curiousity has anyone any experience on costing this type of job?

Oh and we would need to knock a doorway into the garage from the main house.

What about planning permission??

I'd get an engineer to draw up plans and try and see can he get it to regulation also talk to them about your options if you didn't go for planning as it can be hard to get depending on your roof, don't let it stop you though.
Depending on what you want up there I'd say anywhere between 20 to 45k if you want 2 bedrooms and a toilet.
It all depends on the strength of the existing floor, heating system, insulation etc.
It could be well under 20k if when it was being built somebody had planned for the future.
The Toilet and Stairs alone you could loose 8k + easy if you need them. It doesn't be long totting up.

Double garage is attached to the house. No structural change needed.

Planning and structural changes are not inter connected.
You may still require planning depending on the area of change.
