Cordwood Greenhouse in Montana

Hanna fell in love with Montana, nature, gardening and cordwood.  She built a gorgeous cordwood greenhouse/shed and filled it with plants and gardening tools.hanna-montana-3Then she planted a beautiful garden of flowers and vegetables around the shed. hanna-montana-2Finally she added a deer fence to protect the lovely produce and beautiful plants.hanna-montana-1

greenhouse-hanna-montana-2-800-x-600During construction she repurposed windows for maximum light.  hannah-montanss-greenhouse-08a-800-x-600A few stained glass windows add a nice touch to the natural “feel” of the shed. Hanna wrote a blog about her shed and shared it with the website I helped moderate at http://www.daycreek.com   We are hoping she will update her blog and let us know how things are progressing.

Readers have requested a brief bio, so here goes:

Richard & Becky Flatau built their mortgage-free cordwood home in 1979 in Merrill, Wisconsin. Since then, they have written books, conducted workshops, facilitated the 2005,  2011 and 2015 Cordwood Conferences and provided consultation for cordwood builders.  Cordwood Construction: Best Practices DVD,  Cordwood Construction Best Practices (print) and Cordwood Conference Papers 2015 are the newest publications available from their online cordwood bookstore.   www.cordwoodconstruction.org

Cordwood Warming Shelter

We built a cordwood warming hut at the Merrill School Forest that gradually morphed into a public school classroom along the way. The goal was to create a natural building using materials from the surrounding woods for students to warm up in on their winter hikes.
The result is a state code-approved, public school classroom that boldly demonstrates “best practice building” using sustainable methods.  Many of  these techniques can be used with other alternative building methods like strawbale, cob, earthen plaster, adobe and cobwood. Cordwood Education Center Richard Flatau highresjpeg with logo

The building started with architectural drawings and blueprints. These were sent to the state capitol in Madison, Wisconsin to be assessed for code compliance  We were pleased when they were approved. [Note:  In the future this tiny cabin may become a care-takers cottage and so “knock outs” were made during construction to provide for plumbing for a kitchen and a bathroom.]

The wood for the entire building (posts, cordwood, window boxes, paneling, trim) was cut within 1000 feet of the building site.  We used tamarack (larch), pine, spruce and balsam. Crews of community volunteers from ages 4 to 80 turned out to help. OLYMPUS DIGITAL CAMERA

For planning, we started with an architectural drawing.

A rubble trench is much messier in reality.  This poor soil is called “goose nuggets.” sfwh5

A 4″ perforated drain tile surrounds the foundation and carries the water away. sfwh12

In order to satisfy code requirements, we topped it with a Frost Protected Shallow Foundation (FPSF).  Five million of these foundations have been built in Norway, Denmark, Sweden and Finland and they are now approved in the USA and Canada.  They work very well in cold climates, keeping the heat in the building and most are outfitted with radiant-in-floor heating systems.  This type of foundation saves money by reducing materials and excavation costs.

The building was framed using heavy timbers of pine and tamarack (larch).  The roof truss was built with a 14″ Energy Heel so that  starched cellulose could be packed to the outside edge of the top plate, giving the roof an R-value of 53.

The high school construction classes and middle school students came to work and learn.  They wanted to live and work here all semester.

Everybody pitched in.  We had 90 volunteers and 180 folks who came to “have a look/see.”  So, doing the math,  for every one who worked, two supervised :0)

The split faced blocks are needed in this area because of the high snow depth (70″ per year) to protect the cordwood.  The double posts allow for a 16″ wall, which not only provides an excellent thermal mass, but also an R-value of 24.

The sawdust mixed with lime provides a thermal break.

As the walls began to rise, the community came together to help.

The cup end of the dipper points to the North Star.  “Follow the drinking gourd” was what Harriet Tubman sang to her escaping comrades.

The dedication was planned and celebrations took place.  The Cordwood Education Center is now used every day by the students of the Merrill Area Public Schools. It is also used as a Warming Shelter by weekend skiers and hikers.

The students celebrate!

Even the media found this little classroom in the woods appealing.

The local and national media payed close attention to the project.  Many other cabins, homes and cottages have been built using the Cordwood Education template.

Cordwood has a tremendous amount of “thermal mass” which means it has the capability of taking and holding and then releasing the warmth or coolness that has been introduced by passive or active means.   In other words your warm building will stay warm and if you cool it, it will stay cool:0)

Best Practices used in this building.

  • Rubble Trench
  • FPSF  (Frost Protected Shallow Foundation)
  • Natural materials built up (off grade)
  • 16″ cordwood walls (R-24)
  • Post & Beam Framework
  • Energy Heel Truss
  • Large Overhangs (2′ and 6′)
  • Gutters to prevent splashback
  • Metal Roof (to shed extreme snow load)
  • Energy Efficient Windows and doors
  • Passive Solar Design
  • Natural materials sustainably and locally harvested (posts/sawdust/cordwood/lumber)
  • Random patterning of well dried softwood
  • 200 recycled bottles/stones/momentos placed in the walls from the volunteers

Let’s be clear. Not everyone has to use all these best practices.  They are simply listed for the owner/builders consideration.  The choices you make will be based upon your time, talents and treasure.
