All done on the outside, minus a bit of sealing for the frost wall. It is a great barn. It's 10 metres long by 5 wide, with a loft. The cottage will sit at right angles, away to the right. It will be around 8 metres long by 7 deep, but built in the 'saltbox' tradition. Shipboard lap timber over thick plywood, and a simple pitched roof, well-trussed to take the snow -- like the top section of the barn roof, but no 'fall-aways'.
