Great How-To Book
This book illustrates and explains how to create an affordable underground house with far more advantages than an above ground house. Explains step by step planning, materials, construction, features, and some sample layouts to get you started. Along with much more. This is the book I plan to use when I build my house.

Beyond 5 Stars--Inspirational, Valuable, Practical
   This book is phenomenally wise, useful, easy to read, and plain inspiing. I picked it up this morning intending to get back to it tonight and ended up not putting it down at all.....
    The book ends by discreetly recommending a (DVD) series on design as the key element for success, and one that professional architects generally overlook (as we are all learning, the "experts" in finance and other areas are really "credentialed" but NOT experts).
   I LIKE THIS BOOK. As an afterthought, it is recommended by just about every major alternative living, green energy, and sanity outpost (Vermont, Oregon, Washington State) reviewer. This book is a "good deal" and inspiring to boot

A Classic!
Mike is an original thinker/curmudgeon. Everyone interested in building with natural materials should study his ideas. His DVD set is more complete than this book and incorporates 25 years of experience building this way. Get them both.... Kyle B. - December 13, 2008 Amazon 5 out of 5 Stars

"I have fallen in love with this book because it is the answer to most of my greenhouse problems. I was concerned about building an above ground greenhouse due to the fact that I would have to run electricity to the building to heat/cool it. The earth berm concept is so painfully smart am left wondering why more people don't practice this? A must buy right now due to the need for sustainable living!!!!!!!!!!!!!!!
Lana Lambert, Amazon 5 out of 5 Stars
The book covers the theory, design, and construction of the greenhouse (using Mike's low-cost PSP ---post, shoring, polyethylene--- technique): glazing, insulation and ventilation; beneficial critters and those that aren't so; solar energy input: the cold sink system; earth-tempering; and thoughts on how to use the completed structure. …. keep in mind that this greenhouse functions with no heat input in northern Idaho and carries hardier varieties through the winter.
BackHome Magazine



"This design is so unique and so efficient, this is phenomenal …. an amazing greenhouse system"
Jane Nugent, Jane Nugent's Garden Talk, WPTT Radio – TV, Pittsburg, PA


"An interesting, quite complete and entertaining book. The author gives the reader the benefit of many years of trial and error and some well-presented design elements that are not well treated in many other greenhouse books …. He got into greenhouse design choices and did a very nice job …. I liked the book. It was a pleasant read and the pearls of wisdom …. keep up the readers interest."
Tom Karasek, Hobby Greenhouse


"Every winter, gardeners dream of owning a greenhouse—a warm and sometimes sunny place to tend plants and overwinter tropical favorites. If high heating bills have kept you from realizing that dream, this may be the book that inspires you to dig right in. The author lives in an earth-sheltered home and grows his own veggies in a working greenhouse that is heated by the sun. In chapters about glazing, insulation, heat tubes and pest management, you'll learn the basics of a solar-powered greenhouse and be treated to plans, photos and random notes about the process, including the use of rabbits as part of the growing cycle. The solar heat idea will work best if you have a hillside and sunny location, but you can harness the sun anyplace there is light and soil. The author also wrote "The $50 & Up Underground House Book" and his home has been featured on HGTV and in various magazines. Even if you never intend to grow a thing, the book is a fascinating look into the mind of a modern day rebel."
Marianne Binetti, Seattle Post Intelligencer

Mike Oehler (1/2/1938 to 2/2/2016) -- our founder, an innovator in self-sufficient living and the man who literally wrote the book on earth-sheltered housing for two generations of underground builders.

His family will continue this website and sales of his popular books and training materials, and a memoir just completed by Mike of his days in the vanguard of the hippy movement of the 1960s and '70s will be released soon as well.

The Pioneer of Underground housing and “Tiny Underground Homes”, Mike self -published The   $50 & Up Underground House Book  in 1978 (Mole Publishing Co), and had tripled the size of his home/ underground office complex from 120 square feet to a palatial 370 sq. ft., including built-in root cellar and wall-to-wall carpeting. Though totally underground the home/office has 25 windows, sunlight and good views. The original house went from a cost of $50 to $500 and then to $2,000 a few years later with the addition of a really good $500 wood stove and a modest $1,000 solar electric system.

Underground housing is a concept whose time has come again. Its advantages over above-ground housing are spectacular. It stays warm in the winter and cool in the summer. It blends in with nature rather than rearing above it. It can double the yard space in a city. To the neighbors it looks like a park. It is the most environmentally sound. It uses half the building materials. It is the safest form of housing: it is fire resistant, radiation resistant and is impervious to tornado and hurricane strength winds. It even does better in earthquakes.

Where are the traditional tornado shelters located? Where are the fallout shelters? Where does an army go to defend itself? In a world that is increasingly hostile, it’s really nice to know that Mother Earth herself is providing your safety.

The $15,000 Ridge House, now under construction on Mike Oehler's land

Here is what Home & Garden Network (HGTV) had to say about Mike Oehler's underground house, on a special called "The Subterraneans", which has aired frequently. (Check your schedule for future airings):

   "This guy literally wrote the book on subterranean housing and sold more than (105,000) copies of The $50 & Up Underground House Book. He lives in his own creation. It's a little snug but it's custom built and has all the creature comforts. You can barely see it, a dream get away nestled deep in the mountains of scenic Northern Idaho on 40 acres of land. Imagine it, all yours for $500. That's what subterranean pioneer Mike Oehler created when he... built one of the nations first underground houses in 1971... Today his little house in a hillside is a rustic gem... It's like having an underground log cabin... and somehow eight feet underground there's still lots of light here. Mike has developed what he calls an Up Hill Patio, a cut behind the house and into the hill, where plants can grow and light and air flow through the house. MIKE: "I think I've got the only system in the country, maybe the world where you get light, air and views from two or three directions in each and every room in the underground house.'
   "A beautiful mountain side, custom design, self-sufficiency and plenty of natural light even though you're underground, and all for $500. And maybe best of all, tranquility. MIKE: 'Its easy to heat, easy to cool, It's easy on your ears because it's much more soundproof in there.'
   So what's next for Mike Oehler? Well, he's writing a new book and he's designing and building a new (1800 sq. ft. underground) home. It's got a patio, and a tree house, and an underground pool and jacuzzi. And how much for this super house? $15,000.

We know of nothing anywhere which comes even close to matching the wealth of knowledge found in this three-DVD, six-hour DVD set. The design course taught in DVD two alone is worth, we believe, a hundred times the cost of the set in the increased light, air and views it will afford your subterranean home, and in the home’s resale value. If you are just beginning to explore the option of underground housing, The $50 & Up Underground House Book alone will suffice. But if you are convinced you want to build below surface, or need more information to make up your mind, you need this set. It is valuable to owner/builders, self-designers, architects and contractors alike.

3 DVD set

This is the same course author and instructor Mike Oehler has taught for architecture departments at colleges and universities across North America and England, Scotland, Belgum, the Netherlands and Germany. He has the material down pat and is able to anticipate your confusion and questions. Unlike the live workshops, the videos allow you to study the material again and again and to share it with your family and friends.


The first DVD explains the Post/Shoring/Polyethylene (PSP) method of building underground with the warmth and charm of wood. The secret is a layer of plastic which protects the wood from the damp of the earth. The original structure built by this method as an experiment in 1971 is still in service. Instructor Mike Oehler invented it, built it and lives in it today. He is now at work on the stunning PSP underground Ridge House with its twenty-mile views.

The second part of the construction DVD is a slide presentation showing construction and completion of a number of underground homes built by this method. Construction costs can be as low as 1/10th the cost of normal construction -- sometimes even lower.
  PSP Method

This is the heart of the workshop. Using chalk board and the same scale models he hauled for years to universities across North America and Europe, Mike Oehler teaches his revolutionary methods of underground design. Rejecting for the most part the four common methods (the foolish four: skylights, atriums, vertical window wells and the disastrous first thought design) he teaches instead twelve methods which guarantee light, air and views from any and all directions of the compass in each underground room. No more dark, airless, basement-like underground buildings! As Mike likes to say, "An underground house has no more in common with a basement than a penthouse apartment has with a hot, dark, dusty attic."

Students of the course actually design five underground homes during the screening of this DVD using the included copyrighted design kit. These hands-on excursuses not only drill the methods home, they are actually fun! Those who complete this course wind up with a better concept of underground design than the vast majority of practicing architects today.
In the second part of this two-hour DVD, Mike takes you on a personal tour of the four underground or earth sheltered houses on his land. You see real life applications of the Royer Foyer, Hollywood Wings, Up Hill Patios, Basic Designs and more.

This third DVD teaches how to build an astonishingly inexpensive shelter which can take your family and friends through nuclear fallout, tornadoes, hurricanes, raging fires and even earthquakes. After a catastrophe, if surrounding above-ground houses have been destroyed, it may be lived in and used as the starting point for an underground house. In normal times the shelter may be used for a root cellar, spare bedroom, workshop, tool shed or kids play house. The cost of this 12x12 shelter will run from $100 to $1500 depending on how many recycled materials are used and how much of the work the owner does. Comprehensive shelter diagrams are included at no additional cost.

The second part of this DVD teaches how to design and build a spectacularly effective earth sheltered greenhouse. The prototype for this, invented and built on Mike Oehler’s 40 acres in mountainous North Idaho, 30 miles south of the Canadian boarder, has been in service for nearly a quarter century. Without any other heat source than sun and earth this greenhouse takes tomatoes into the second week in December and hardies like cabbage and kale clear through the winter year after year.

The greenhouse is resistant to the ravages of gophers, moles, deer, rabbits and most other plant predators. It can even collect its own irrigation water. A 10x30 greenhouse should cost between $200 and $3000 depending upon materials and labor.

The third part of the shelter DVD continues the tour of the underground structures on Mike’s land including the earth-sheltered greenhouse.

The Earth-Sheltered Solar Greenhouse Book  has 230 pages with nearly 200 illustrations, photos, diagrams, lists, charts and drawings. It contains all the information you need to struggle free from the pesticide, herbicide, fungicide, waxed, E-coli laden, genetically modified and irradiated supermarket produce. It promotes organic food grown in the closest local spot of all, your backyard. It does all this and saves you a bundle of money too! The Earth-Sheltered Solar Greenhouse Book  details the benefits of both passive solar energy and earth sheltering in greenhouse design. This combination results in greenhouses which need no heating. The captured sun's energy and that which is stored in the earth is enough for successful year round harvest. Gone are costly heating bills. Gone is the squander of nonrenewable energy resources and the resultant atmospheric harm.

Earth Sheltered Solar Greenhouse Book

Winner of the Nautalus Book Award

This is because above-ground unheated greenhouses get natural heat at night from only one side, the floor. They lose heat from the other five sides. The properly designed earth-sheltered greenhouse is naturally warmed at night -- and in the winter -- from five sides and loses heat from only one, the carefully selected glazing. The ratio is exactly reversed. This book tells all. It takes you step by step through the construction of an inexpensive greenhouse which may be built with either newly purchased or salvaged building materials at great savings. It explains the author's unique Post/Shoring/Polyethylene construction methods which Countryside Magazine called “Revolutionary... innovative and ingenious... a totally different concept.” The book deals heavily with design so that the reader may custom-build a greenhouse perfect for the particular climate and needs.

Mike Oehler shows his Earth-Sheltered Solar Greenhouse to Paul Wheaton of Permies.com

It tells :

• How to use gravity to warm winter plants

• How to effectively capture and store the sun's heat

• How to make up for poor sunlight free of cost

• How to automatically vent without power

• How to choose the best glazing for your project wheelborrow

• Where to find free building materials

• When to use heat tubes and when not to;

• How to use a root cellar in tandem with the greenhouse

• Where to use insulation with wonderful effect (and where to absolutely avoid it)

• How to deal with plant pests organically

• What animals should be living in the greenhouse? 

• And hundreds of more tips. Seasoned gardeners will immediately understand the great
benefits of growing in a greenhouse that needs little or no additional heat for year round
harvest. Beginning gardeners will discover the deep joys and therapeutic value of gardening -- without the bitter disappointment of seeing their hard won plants freeze to death in the fall. All gardeners will appreciate the year round healthful, flavorful food, food that is almost free of cost. And all gardeners will greatly appreciate being able to work or lounge in the sun on the bitterest winter day. It's like being in Florida or on the Riviera without the expense and inconvenience of travel.  With a little adaptation your greenhouse might serve as a storm shelter also, seeing as part of it is eight foot deep. It could conceivably keep a family alive over a winter when fuel was not available. And, of course, it could feed a family were food the food supply disrupted.  A year round therapeutichoe
hobby; basking in the sun on bitter winter days; gloriously healthy food; a corresponding decrease in medical bills, not to mention food bills; plus shelter from the storm and civilization's failure are compelling reasons for building an earth-sheltered solar greenhouse.  Peter Andrews, founder of Eco-Logic Books in the United Kingdom calls The Earth-Sheltered Solar Greenhouse Book a, “Splendid, practical handbook -- essential reading for anyone looking to extend their growing season. Thoroughly recommended.”
