With a rectangular shaped floor, it uses the southern façade of Talaiot 2 as its rear wall. It is the most well preserved house.

After going through the doorway you go down two steps and enter a small hall which leads to an open air courtyard. The floor of the patio was paved with limestone slabs which allowed the rainwater to be channelled into a cistern. Also in the patio there was a hearth attached to the northern wall (which in more ancient times had been the façade of Talaiot 2). In the interior of the house there are two rooms: one used for the task of grinding cereal, and the other for a potters workshop and a warehouse. The domestic units in the post-Talaiotic period used a great deal more objects than were used in the Talaiotic period. The storage space grew due to an increase in food production based on agriculture and livestock farming.
