I bought the kit for this Knight's Castle at the Arnhem Dollshouse Fair from VA-Holzkunst, who had many amazingly tiny laser cut kits on their stand. I gave them my email address and they emailed me directions in English. The kits are laser cut from extremely thin wood. The young man on the stand assured me this kit would be very easy to put together even though it looked difficult. Having now put it together, I'm not sure I would classify it as 'very easy'. It took dexterity, and ultimately the use of DH's magnifying visor, and lots of breath holding as I desperately hoped that whisker thin scraps representing knights did not go 'ping' out of the tweezers.
The towers are perforated at each corner, so you can carefully bend the wood into a box shape using tweezers. Each tower has a roof piece that slots in, and the entire tower slots into an individual base. After you have bent the tower into a box shape, you insert the roof piece by putting its tabs into the slots in the tower walls, then glue the final corner of the box, then glue the tower structure into its base.
Here is the finished castle in my boy's room. It was very fiddly to do, but I am pleased with the final effect and it is very appropriate for my castle-themed bedroom.
