What Is Earth Building?

Building Naturally, the Old Way.

Natural building means making shelter from minimally processed, local materials — earth, sand, clay, straw, timber, and lime — instead of concrete, foam, and vinyl. Earth building is the heart of it: using the very soil under your feet to shape walls that are warm, breathable, non-toxic, and beautiful.

It’s one of the oldest building traditions on earth — and there’s something remarkable about walls you can shape with your own hands, that regulate humidity, and that feel alive in a way drywall never will.

🏔️ Rare in Appalachia. Most earth building in the U.S. happens in the dry Southwest. Doing it here in the humid Southeast takes a “good hat and good boots” — deep roof overhangs and raised stone foundations that let earthen walls thrive in our mountain climate. We’re among the few teaching it in the region.
Skills You’ll Take Home

What You’ll Learn

Every workshop is hands-on. Depending on the session, you’ll mix, sculpt, stack, and trowel your way through techniques like these.

🏺

Cob

Hand-sculpt clay, sand, and straw into thick, monolithic walls — the most meditative and freeform of all earthen methods.

🪵

Cordwood Construction

Stack short logs in a mortar matrix to build beautiful, insulating walls made straight from the forest.

🎨

Lime & Clay Plasters

Mix and trowel natural plasters and clay paints to give any wall a warm, breathable, earth-toned finish.

🧱

Adaptations for Wet Climates

Weatherproof earthen walls the Appalachian way, with breathable, mold-resistant lime plasters and washes.

🌾

Hempcrete

Cast a mix of hemp hurd, lime, and water into insulating, breathable, mold-resistant infill walls. A great fit for our mountain climate.

🔥

Cob Ovens & Finishes

Sculpt a wood-fired earthen oven, pour an earthen floor, and seal it all with natural oils and pigments.

Upcoming Workshops

A note on our 2026 Cordwood dates: we’ve combined this year’s cordwood sessions into a single workshop on October 23, 24 and 25. The change is for a happy reason. A close family member is getting married, and we wouldn’t miss it for the world. Thank you for your flexibility!

How It Works

What to Expect

1

A Hands-On Weekend

Most workshops run two days, starting around 9 AM. You’ll spend your time building, not just watching — with demos and Q&A woven throughout.

2

No Experience Needed

Come as you are. Our small groups are beginner-friendly, and you’ll work shoulder to shoulder with folks of every skill level.

3

Make a Weekend of It

Add a cabin stay and settle in on the bluff. Mornings on the trails, evenings by the fire, and real skills to take home.

4

Leave with Real Skills

You’ll walk away understanding soils, mixes, and finishes well enough to start your own natural-building project.
