Having finished the base and the barge, the buildings are constructed in order, Building A, B and C. The key here is to get good quality card that won't bend. Unfortunately some of the card I was using wasn't that good, so the finish isn't as good as I was hoping for. I could rebuild them of couse, because once you have downloaded the kit you can use it over and over again, but I first have to source a better quality card. They also recommend three different thicknesses, and the parts fit together best if you stick strictly to the thickness of card suggested in the instructions.
Anyway, here's building A in progress.
The picture below shows where the building will fit in the box file. A backscne will be added on the lid, and they send two versions, an A3 version for if you have an A3 printer or two A4 pieces if you haven't. You will see it later. The back wall of building B is also visible in this picture.
That's it for part one, buildings B anc C will follow shortly.
