Their Rouke's Drift set was a pleasure to build. It went together well and easily. The roof is done in the same way as this one, with laser etched tiles or teddy bear fur for a thatched roof. The surface is a bit plain but stippling with texture gel or possibly an application of very fine sand should fix that. Mine are sitting built but unpainted until I decide how to finish the walls.
This tower tempts me a lot, it is the railings that I would find the hard bit to make, and the reason there is a half built one hiding somewhere, the rest is easy peasy. It would be useful for fantasy games as well as historical.
