Rammed earth is a building technique that uses packed raw materials from the earth like gravel, sand, silt or clay to build walls and foundations. Casa Lasso, designed by Rama Estudio in San Jose, Ecuador utilized the rammed earth approach (or “tapial”) to create five strong walls made of natural elements to both protect the home from strong winds and improve the thermal quality inside the home.

The rammed earth provides added support for the wooden-beamed roof every 70 centimeters. Glass windows make up the upper closures of the structure, giving the entire area the potential for sunlight to shine through and light up the living areas. Speaking of living areas, there is room for six beds, all built into the rammed earth framework, in the communal area. There is also a master bedroom with pivoting panels to either integrate or close off the spaces.

Much of the furniture and shelving in the kitchen and bedroom is built into the structured wall, ensuring that no space is wasted, no matter how small. The designers built the rustic fireplace into the lowest part of the home, with the intention of creating a centralized space that would “embrace” the area. Casa Lasso also uses a waste management system that connects solids and liquids into an internal irrigation and fertilizer network, meaning that there is no sewage system.

Using pivoting panels, occupants have the option of closing the doors for added warmth and security or creating an extended and almost unblocked view of the outdoor area beyond the property. The area around the house is surrounded by eucalyptus plantations, making the land arid and soil difficult to grow in. Designers chose to plant native species in small landscaped islands throughout the property in order to combat this dilemma.

As a result of the rammed earth building technique, Casa Lasso maintains an organic color. The combination of brown earth tones from the wooden panels, the large beams making up the roof and natural stone work makes this home blend in beautifully with the native landscape.
