The Lurrean House is constructed of unfired earth block. In keeping with our belief in the use of locally sourced materials, earth from the site itself, which has properties that are perfect for controlling heat and humidity, was employed in building the load bearing walls. This type of architecture gives the building the nobility of the old bourgeois houses and the robustness of a typical century-old farm in the Basque Country. The natural materials used and this silent process of building, done without machinery, allow the house to discreetly blend into the very landscape from which it came.
