Natural Building Certificate

Natural Building Certificate Workshops

Our Natural Building Certificates will be awarded for attending one of our 2-5 week Natural Building Certificate Workshops. You will get opportunity to study and build with natural building materials and green technologies hands-on. Understanding the climate and environment of the building site is essential to designing a building that is appropriate for it. In times of a climate crisis it is particularly important to us to teach you about embodied carbon. Namely how to keep it as low as possible in your building. After this workshop you will know how to build unique, eco friendly, resilient, long lasting structures with local and abundantly available materials. From foundation to roof, including planning, sculpting, plastering, electricity and plumbing inside the walls, you will learn how to build a house, by doing it.

The Natural Building Certificate Workshops are an Introduction to Natural Building techniques and green building technologies. This includes hands-on practice with natural rock foundations, insulative as well as thermally massive wall systems, earthen floors and plasters as well as natural paints and finishes. Depending on the host’s project, workshops can include extras, such as green roofs, reciprocal roofs, green houses and others. In a Master Natural Building Certificate Workshop you will get 175 hours of practical experience plus 25 hours of lectures. That is an intensive 200 hours course, that will change how you think about living spaces.

Who is a Natural Building Certificate for?

Our Natural Building Certificate is for everyone who wants to know what alternatives to conventional building technologies are out there. Whether you are environmentally conscious and want to reduce your carbon footprint, or surround yourself with healthy natural walls. Whether you want to build cheap by doing everything yourself, or because you want a hand-sculpted house reflecting your creativity. Natural Buildings can give you all of that. Our students come from all over the world. Whether man or woman, young or old, Natural Building is for everyone. With the knowledge from this course you can get started building your own home or become a professional Natural Builder.

Please consider that this course will be physically demanding, as we are building a whole house bare-handed and -footed. If you are not able to do hard work please let us know before the workshop, so we can arrange other task for you.

Workshop Requirements

There are no skill requirements for the Natural Building Certificate Workshop! That said, it certainly won’t hurt if you know some things and put it to good use or share it with others. Nobody is perfect and we are always curious to learn other ways of doing things.

Please bring an open mind and be prepared to do some demanding physical work from Day 1.

Essentials to bring

  • Watch or Phone to be on time (bring a charger)

  • Rubber dishwashing gloves (thick, for lime mortar)
  • Work Gloves (rubber palm, breathable back)
  • Eye and Ear Protection
  • Sunglasses
  • Hat
  • Dust mask
  • Clothes to get dirty appropriate for the country and climate we are in
  • Work boots
  • Flip-flops for cobbing days
  • Good Moisturizer
  • Water Bottle
  • Notebook and pens / pencils
  • Camera
  • Sample of Your Soil (Optional)

Good to have

In short, bring whatever you NEED to be comfortable and happy when camping for over a month. 🙂 There are many local stores in case you forget something or prefer to buy it in Italy! Our recommendations for stuff to bring are:

  • Bathing Suit for swimming in the sea, we have almost no waves here and the water is pretty warm, windsurfing might be an option though
  • Clothing for hiking
  • Warm jacket for evening time
  • Chocolate! Or whatever essential snacks you’re craving
  • Pillow and favorite cuddle blanket

Optional: if you like to bring your own tools

  • Measuring tape (ideally with inch and cm)
  • Level (60cm / 2ft)
  • Utility knife
  • Carpenter Hammer (the one that can remove nails)
  • 10-15cm / 4”-6” diameter round plastic yogurt lids (for plastering)

Be prepared

Please read “The Natural Building CompanionAce McArleton, Jacob Deva Racusin” (all in one, quite technical) or “The Handsculpted House, Ianto Evans, Michael G. Smith, Linda Smiley” (cob, inspirational) before arrival, you won’t have much time to read them during the workshop. Watch some videos on YouTube about natural building and browse our gallery to get an idea of what to expect from the workshop. Please bring your book(s) and any other books or poems to share as well as slideshows, videos, movies, and downloaded building site music playlists!!!

Take care of yourself

Make sure to take care of your personal needs, drink a lot of water, rest when needed and exert yourself at a steady pace. Let us know if you cannot do hard physical work before the workshop begins, so we can adjust accordingly. It is totally OK to come for the lecture/theory part, and then help the building part in less physically demanding ways, for example cutting straw, sifting for plaster, hammering nails into frames or shelves, sculpting, plastering, cutting bottles. There is a lot to do besides making and building!

Share what you are good at

If you are a qualified teacher or leader in something beneficial to our month-long time together, and would like to offer it up, please don’t hesitate to speak to the Instructors before or during the Workshop! We are open to non-building activities in the evenings and at night…if the energy is there of course.

Important Information

You will be fed 3 delicious meals a day during the weekdays, prepared by experienced cooks.  Suski workshop hosts always serve amazing food to students in gratitude for their hard work! We will be providing mainly ovo-lacto-vegetarian food. Therefore we can be sustainable and meet most culinary tastes. Depending on student’s needs we could have fish, meat or vegan options however. We will try to meet people’s requirements, so make sure to communicate them as soon as possible. On weekends, food will be available on site for you to prepare.
