This is a Build-a-Dollhouse kit, specifically a kit to build the Shirakawa-go Gassho-style farmhouse, a UNESCO World Heritage site. You'll likely feel a great sense of accomplishment upon completion. Please enjoy the process of building it! I opened this to check the size, but the finished size wasn't listed. Size: Base size: 14cm (length), 19cm (width). Overall height is unknown, but probably over 20cm. I purchased this through a co-op delivery service several years ago. It's new. Thank you very much.
