One of the common characteristics of the houses in the Campidano area was the use of the làdiris. It was brick ( from the latin later, brick) made composed of a mixture of mud and straw then dried in the sun. Often it was made personally by the owners themselves to meet the needs of the growing family. This completely natural material has the main advantage of being an excellent thermal and acoustic insulator. The house made of làdiris are well known to be both cool in the summer and warm in the winter, protecting from outside noises, which was healthy and peaceful. The disadvantage, on the other hand, is the low capacity to withstand high pressures, which is why the Campidanese house is usually on two levels only (ground floor and first floor).
