The Dapol HO scale Windmill and Country Tavern, small for 28mm but the footprint is handy and you can base them so they look taller.
A really nice barn from the Wills, railway scenery, same thing as the Dapol but much better quality.
A couple of old Hudson and Allen thatched houses.
Some precut card buildings which I suspect will defeat me in terms of construction. I bought them on a whim and then realised I'd had the same problem about 20 years ago. Same bloody kit too.

The Italeri bridge. This thing is a monster. Actually I'm wondering where and when I'm ever going to use it. Goes together easily enough although to want to do a dry fit first. I'm really excited about the prospect of their new church building, which looks sensational. Oddly enough it's not listed on their web catalogue, yet they seem to be stocked in Europe.
