Dry lining a concrete garage

Of course it is. You can do it direct to the walls with bonding plaster or you can make it damp proof and warmer with a sheet of Visqueen and some rock wool. That will need studwork though and that will reduce the size of the office space somewhat.

Get some 2x2 inch rough sawn treated timber and make sure you get straight bits. A timber yard will chop it to the sizes you want if you are willing to wait for the service.

Pin the Visqueen to the top of the walls and put a length of 2x2 every

You may have trouble fixing the studding to the walls so you had best make it as a frame. A small one should be able to support itself with a little help from braces and a few fixings in the floor.

In which case tack the Visqueen to the top of the frame after you make it but before you offer it up. Put a cross piece (called noggins - no idea why) in between every stud. Put in any wiring and whatever else, then the rock wool then plasterboard it.

One little tip if you intend to just paper the board, cut off the edges where they are dished to take scrim or tape. Or use the type that have just flat, undished edges.

|!Hello |! |!We have just moved to a new house that has a concrete garage which we |!would like to turn the rear half into an office.

Don't tell the local planning authority what you are doing!!! They may well want you to get building regulations approval for the changes, and insist that all the windows, services etc. are to the same standard as the house.

Yes. use a vaopupr barrier in fromt of te insulation.

My choice would be stids with celotex between,taped over with foil tape and plasterboarded out.

Agreed and it uses much less depth for equivalent insulation than would be required for rockwool or glass fibre.

Not just may ----- a 100% bet, this is a material change of use .... and this would come under planning and Building Control .... if they found out about it.
