A lot of people ask me about the detail of how my house is built so I thought it worth a thread to explain things. First off, I didn't want an "ordinary" timber framed house with a cavity then a brick or block outer skin. That outer skin just costs a lot of money and adds nothing to the insulation of the house, it's just an expensive rain shield. I still wanted the traditional Scottish look of a white rendered finish but I want all elements of the wall make up to add to the insulation
