The Retreat at Blue Mountain Farms in Costa Rica is adding cordwood buildings to its accommodations. Cordwood Construction Resources has been providing consultation for the project. Utilizing the native tree (Pachote) the local masons (led by Chris Olson of Minnesota) are working to develop an eco-friendly mortar that will both stand the test of time and not tax the planet.  Here is the stunning result of their first building. 

Since this is a tropical climate the cordwood walls are 8 inches and the mortar runs the full length of the wall.

This retreat is located in one of the world’s Blue Zones.  “Blue Zones are identified areas where people live long, productive and happy lives.  five places in the world ­– dubbed blue zones – where people live the longest and are healthiest: Okinawa, Japan; Sardinia, Italy; Nicoya, Costa Rica; Ikaria, Greece, and Loma Linda, California.”

Beautiful framing and screen placement helps to bring the outdoors, in, without the bugs.
