All help and advice gratefully rec'd.  I have removed units and tiles from a bedroom/living room and have a wall with residual adhesive and a damaged surface plus some external pipes (part of central heating).  I plan to build a stud frame (using 2 1/2" wood) then nail plasteboard to it thus losing a small part of the room but with a smooth surface to decorate and ugly pipes hidden.  I know there are lots of 'it depends' however does this sound like a reasonable plan - any obvious gotchas?  Thank you for your time.

Thank you. Sounds good.
