The deforestation problem that constantly threatens our global forest resources is one that we can overcome. To accomplish this, though, we must again learn to give our forests real value. The main idea here is that our forests must be more economically valuable in their current state than they would be under competing land uses. If not, they will be deforested.
We recently completed our adobe shower and thought we would share with everybody how and in what order it was executed. The building blocks of the design were Adobes that we made with our 2018 apprentices and student groups that visited us through the year

In the natural building world at Rancho Mastatal there is no lack of projects to be done. I think as a team we have collected a list that will take us past 2020. And we already have been building our infrastructure for the past 16 years. One could say we are natural building addicts!
Over the years of natural building at Rancho Mastatal my feelings on the process have gone through many stages.

To over time, after building many walls, an understanding of how long it takes to build a natural home and all the work that it entails.
On the building list one of our goals is to correctly re-plaster old structures to enhance their look and highlight our unique architecture. Over the last couple years we have slowly been giving our old structures new face lifts. Using lime plaster techniques that we have been learning, practicing and perfecting we have transformed various run down plasters into beautiful canvases of art.
