Ancient and modern solar technology at Earthwood: a megalithic stone circle in the foreground and photovoltaics in the background.

Earthwood Building School is in the northeastern foothills of New York’s Adirondacks, close to the Canadian border.  We’re an off-grid facility getting all of our electricity from solar energy. Over the years more photovoltaic panels have been added, the last  in November 2016.

Because Earthwood is in a reclaimed gravel pit the only viable option for a vegetable garden is raised bed gardening and we have found that ‘raised raised’ beds work really well for us. They help keep most animals out, and, most importantly, they’re great for your back! We have also experimented with hugelkultur, a mounded garden.

The Earthwood campus has a variety of cordwood masonry buildings which hundreds of students have helped to create.  They include four guesthouses, a bookstore/library, sauna, mess hall and garage.  All have living roofs.

Stoneview Guesthouse

Stoneview Guesthouse is an octagon.

In addition, various big stones have grown in numbers, some during Stone Circle Workshops. The stone circle is a gathering place for workshop introductions and evening socials where students can get better acquainted. A positive aspect of workshops is the feeling of support from other like-minded students. Cordwood building draws a special group of people!

Earthwood Building School maintains a variety of pertinent books available for the owner builder, but it’s hard to compete with the big companies.  So …

Why order books and videos directly from Earthwood?

  1. Rob Roy’s books are signed by the author. Big deal. But see the next item.
  2. Roy’s Cordwood, Underground, Stone Circle and Timber Framing books are the textbooks for our workshops. If you purchase them from Earthwood – we know, because they’re signed – and then decide to take a workshop, you get a full deduction of the book cost from your registration.
  3. You help support small business instead of big business … so that we can stay in business!

The Beauty of Cordwood Masonry Construction

Cordwood masonry construction is an inexpensive, sustainable way that anyone can use to build beautiful homes and more.

Children, grandmothers and beavers can all build cordwood homes and so can you. We teach in the U.S. and internationally.

Took the week long class, add 5 1/2 yrs building and now mortgage free. Love the house everyday. The roundness makes me feel more secure than any square or rectangular house I have ever been in. Thanks Rob and Jaki!

My wife and I had the wonderful opportunity of visiting Rob & Jaki Roy at their home in New York. They let us stay with them for an evening and it was wonderful. Their completed projects are a work of art and so are their books, which I had the pleasure of reading before meeting them! If you are looking for something different and inspirational for creative living, start here, you won't be disappointed!! 🙂

Rob and Jaki are both such friendly and knowledgeable people! I had the pleasure of doing the 5 day workshop and can't wait to start building my own cordwood cabin!
