This is Billy's Miyama thatched-roof farmhouse. It's a kit for creating a heartwarming, thatched-roof, old folk house. You'll surely feel a great sense of accomplishment when it's finished (^o^) Please enjoy the process of completing it m(_ _)m Unopened, so the exact size is unknown. Size: Approximately 14.7cm in length, approximately 19.7cm in width (measured the board from the bag) Height is unknown. Probably over 20cm. I purchased this through a co-op home delivery service several years ago. It's new and unopened. Thank you very much m(_ _)m
