The reddish earthen tone contrasts with verdant surroundings, but depending on the season and position of the sun, the home appears to be integrated with the landscape.
"It was sought that the original fact of this construction in an isolated, wild place was a maximum signal of the arrival human presence in the landscape: straight lines marking the soft topography," said the studio.
Set on a concrete foundation, the rammed earth construction is composed of earth, sand and clay to create a wet mixture that is placed in between flat panels to harden. The studio said this technique allowed for easy, efficient and affordable construction on the site.
"An authentic formwork system was proposed that avoided perforations with metal bars and developed a more efficient building site so that its modulated components could be disassembled and reassembled with ease," it explained.

More rammed-earth walls were built further from the house to protect it and buffer from strong winds that pass through t...
