Hi all, Terri is 3 years old and is in need of a new more permanant home so I have started building her insulated home in the back garden. I live in Kent SE England so need insulation for the winters. Started with a fully re-inforced base to take the weight of the walls and roof. Then the walls double skin with 50mm insulation between. This is up to date will be making door and windows over winter and carrying on in early spring, will keep you posted.
