I finished this a few days ago. I know a lot of Samurai were as poor as church mice, and often lived in quite basic houses, I wanted a house with a tiled roof. So I took a 4Ground 'Village Elder's House' and added some corrugated paper and styrene tube to make a tiled roof. I realise it isn't 100% authentic - I should, really, have done some serious surgery on the roof to make it into a 'hip & gable' roof rather than just a gable roof, but it seemed like a lot of complicated work and I wasn't sure I could pull it off... I might have another go sometime though!
