A roof style found on vernacular houses *minka 民家 in Saga Prefecture and the southern part of Fukuoka Prefecture. The main roof of the core building omoya 主屋 (see *hon'ya 本屋) is U-shaped in plan. The style emerged during the last decades of the Edo period. The main roof is thatched and hipped, and each room is narrow in cross section, 2-2.5 *ken 間. Typically, a long room runs along the front, with shorter wings, tsunoya 角屋, projecting to the rear at each end of it. There is a gap between the projections at the center of the rear elevation, which is given a mono pitch roof of pan tiles *sangawara 桟瓦, draining toward the rear. This roof form was called kudo-zukuri by modern researchers because of a perceived resemblance to a cooking range, kudo くど. The local name is *kagiya 鍵屋 or *magariya 曲屋.
