What is Cob?

Cob is a sustainable and natural building material that is typically made with straw, water and subsoil.  A few of the main ingredients used in cob construction, are clay and straw.  Cob construction is one of the lesser known sustainable options.  Here at PSE, we typically get asked about earth bag construction, shipping container construction and straw bale construction, which are all great options as well.



1st Commercial Code Approved Earthen Building on the East Coast!

Back in 2016 we were approached by one of our our clients that was interested in building an Eco-heal center out of cob.  He had an excellent vision, along with ready made architectural plans for us to review.  After discussing the project further with him, we decided to make the leap and take on the project.  It turned out to be a great success and is known as the first commercial code approved earthen building on the east coast.  The Eco-Heal center also contained a living roof, which was an awesome touch to the look of the building and the sustainable feel of the building.

The Ecoheal Center is a 1500 sq ft, 12-sided earthen building completed in the spring of 2017. Being the first commercial code-approved earthen building in the United States, the Ecoheal Center is an educational hub for those seeking an economic, practical, and efficient way to build naturally.
