Evening,

I am looking to take on the task of converting a free standing brick and flint garage into a 2 bedroom holiday home. I am in the early stages of getting this project underway but one issue i have come across is regards insulation of the walls.

My initial plan was to build and internal stud wall, with a vapor barrier on the back, 60mm foam boards in the framing and 20mm foam boards over the top, before covering in platerboard. However there are one or two areas within the garage that have the flint brink showing on the inside and the wife would like to keep these viable. Is this a good idea or should we be looking to cover these areas also.

Thanks

Andy

If you're going to convert the building into a habitable space then you will need to meet building regs for all the works. Leaving exposed single skin walls isn't likely to be approved. I suspect that you may need more insulation in the walls to meet standard (as well as the ceiling and floor).

Have you applied for planning permission and how are you planning to get building regs sign off?

You would have a cold bridge with exposed flint on the inside if there is no break between outer and inner faces of the wall . As others have mentioned the conversion will require building regulations approval and it would be best to have an architectural designer draw the plans and submit a Full Plans Submission which would include insulation details as well as information covering all other bldg. regs related matters. Planning permission is another matter but will most likely be required.
 
Thank you I thought that might be the case for the outside wall. Would that still apply for an internal wall?

You can do what you like with an internal wall. If you can salvage some flint wall you could always make a small feature of it. Sounds like hard work though!
Based on extensions I've had done recently, you'll probably want about 75mm kingspan (or similar) on the floor, 100mm in the walls and 100mm+ on the ceiling.
 
There isn't the same issue with a cold bridge in a partition wall between internal rooms.
