The construction system of Casa Tierra was done with Pressed Earth Blocks (PEB) made from soil of the same lot. This system was selected because it is aesthetically pleasing as well as cost and energy efficient, fire and pest resistant, virtually soundproof, durable and structurally sound.

Compared to other systems, it is more flexible and does not affect the width of the walls. The soil was pressed with 3% of concrete and 7% of lime, being 90% of the material needed for the construction obtained directly from the lot...
