The Kas di Pal'i Maishi, also called the Kas di Yerba (House of Thatch) or Kunuku (Rural) House, represents the indigenous Curaçao dwelling that dotted the countryside in bygone years. The slave dwelling by origin, the Kas di Yerba was built of locally available materials and according to locally developed building techniques. The rectangular plan of more or less 40 square meters and the symmetrical set-up with an entrance in the middle, originates from the West African region, the place of origin of the slave population brought to Curaçao.

The walls are tapered and constructed of wattle and daub filled with stone particles, or simply a rubble stone pile construction, with a clay plaster finishing on both sides. The floor was sealed with a mixture of clay and cow dung to acquire a firm and durable surface. The hipped roof was covered with palu di maishi (sorghum leaves), resting on rafters and purloins for which tree branches were used. The materials used were highly effective as protection for the hot sun.
