Do I need a cavity wall in the footing of a ground bearing slab or just single brickwork and start cavity on top of slab and is it just for a suspended slab you need an inner leaf
Can anyone tell me the cheapest route when I am buying floor and wall insulation for my 21m2 floor extension to side of house and 30m2 walls
Whether I can use jablite 100mm or does it have to be kingspan, celotex etc
Can anyone advise on my what to do with my gas and electric meters outside the side gable of my house as I want an extension building and they are in the way where the front wall is going
Where they are now I want an internal door to new room
What should I do ?
