So, here is the new two-part barn:
Very nearly finished, because the galvanised doors have to be painted juniper green at some point to match the cladding of the rest of the structure. The lower pair are sliders and the higher pair side-hinged, and amazingly everything seems to work well despite the sloping site. We now know that 80 tons of stone went into levelling the floors - it will be great to have our first level working sites, and under cover, too.
What a lot of stock items I'm going to be able to fit in!
