These are the upcoming new Warhammer Fantasy Buildings which Games Workshop will be releasing at some point in the future. There seem to be three buildings and there will also be a release of other terrain such as hills, fences and graveyards.
This is a boxed set looking like it contains both buildings, lots of other scenery and even the hills.
These are the other two buildings, which will be available as separate boxed sets.
I do quite like these, they don’t really fit in with my Steve Barber models, but they are nice.
