The Straw Bale Café

by Jim Merkel

It all started with a concept, a dream, that a cozy, artful 300 sq-ft home and business sufficient for two love birds could be built for $1,500 with an ecological footprint a fraction of standard housing. Even before we broke ground, a hand painted sign announcing the “Straw Bale Cafe” was hung between two twisting birches to welcome mountain wanderers. We wanted to create an example that was replicable by average people with average skills. The decision to use mostly simple hand tools was founded on our love of the sound of a Ruffed Grouse beating its wings, the breeze exciting aspen leaves or the air forced through the tips of a raven’s wings. A thread of our life purpose is to live equitably among the 6 billion humans and 25 million other species. As household construction and heating are the second largest contributors to environmental impact, behind cars, making this dream a reality felt necessary.

While most North Americas work 30 years primarily paying for their house, we felt sad that so many people’s life energy goes to mortgages instead of serving others or the Earth. In the end, the Earth bears the costs of our luxuries, suffering from clear-cuts, mines and pollution while our house sits empty all day while we work to pay for it. Why give our life energy to forest companies, bankers and a myriad of corporations making all the toxic materials that humans typically surround themselves with ? A quantum simplification in housing could free enough people to begin to turn the tide!

Before ecological footprinting (EF) was developed by Bill Rees and Mathis Wackernagel at the University of British Columbia, it was difficult to know if our lifestyles or housing designs were sustainable. EF measures the land needed from around the world to provide each person’s resources and absorb the wastes. By dividing Earth’s bio-productive areas among all humans, each has a 5.3 acre share. However, this leaves nothing for the 25 million other species. My partner, Erica Sherwood and I decided our goal was to leave 80% of our 5.3 acre share wild, meaning we would have to learn to meet all our material needs from 1 acre of Earth (Americans use 24 acres, East Indians use 2 acres). This is our personal, measurable sustainability definition. Read on to see how the Straw Bale Cafe measures up! The first stage was establishing our design parameters:

1) Affordable by 90% of humans. Our goal: $1,500 USD (5 years salary of an East Indian).

2) Living space on a par with global citizen: 150 sq-ft/person (740 sq-ft/person is US average).

3) Ecological Footprint (EF) for housing to be 0.1 acre/person of the total EF goal of 1 acre.

4) Sufficient insulation and solar input to use 1 cord of wood, resulting in an EF of 1 acre for heating, cooking and hot water.

5) No toxic materials; minimal synthetic or store bought materials.

6) Use of materials primarily from on site or from our bioregion.

Meeting these constraints felt easy after witnessing common sense solutions scattering the countryside of communist Kerala, including a father and son building a house from timbers and bricks made on site. However, back in North America, building a simple home is not so easy, so our next stage of the project was:

Prayers

Our site was sufficiently wild that we did not fear arrest for holding a ground-breaking ceremony around an outdoor fire and praying. Although our home/office/cafe was to be tiny, still over 100 trees would die and Earth’s skin would be torn open for sand, clay and lime. On the assumption that we are similar to most two-leggeds, the cougar, bear, deer and marten will stay clear once the home is built, effectively shrinking their habitat. So we said, “I’m sorry,” “thank you,” and sang some pretty songs so the forest knew we meant it.

The Building Process

Lots of friends became the cornerstones of this project. On a crisp autumn day we dug the perimeter trench for the 12' X 15' inside area that was18" deep and packed it with loose rocks to create a platform 25" wide and 10" above the ground level. Then we made a platform from cedar poles for the 18" X 14" X 36" straw bales to rest upon. Two parallel 15' poles of 5" diameter were capped on each end with an 18" 2 by 4 and four identical sections were built, then staked together and leveled. Maple spears of 2.5" diameter were fastened vertically to the cedar rounds rising enough to pierce midway into the second course of bales, giving the appearance of a bizarre torture device.

All 6 courses of bales were placed and pinned with long maple spears. Four more sections of 15' cedar poles, similar to those described for the foundation capped the top of the load-bearing bale wall. The outer north and south poles were 27' long to provide a 4' and 5' overhang on the east and west walls respectively, which includes a balcony that overlooks the snowcapped peaks of Mt. Dag and Wolves’ Ears. Upon this platform, the ceiling and roof structures were made using Douglas fir poles. A dormer on the south side lets in lots of light and makes for a spacious upstairs love nest.

A metal roof was installed, and beneath, 10" thick straw bundles were tightly wrapped with twine and tied in between roof rafters for insulation. Long roof overhangs keep the bale walls dry, even in a rainforest. The whole building was allowed to settle for one winter with the heavy snow load which compressed the bales six inches making it ready for mudding.

The following summer, 3 coats of adobe were applied straight onto the straw with the first coat mixed a bit soupy and smushed into the straw. Our mix consisted of 80% sand, 10% lime and 10% clay with a 14 oz can of concrete and a 28 oz can of wood ash added to each wheelbarrow load for good measure. All materials were gathered within a 5 minute walk except for 250 lbs of lime and concrete from the devil. Once dry, the curvaceous finish turned a sensual golden-brown Earth tone.

A Home Tour

As I sit at the breakfast nook in the SW corner, I gaze across the 12' expanse to the kitchen counter formed by a beautifully curved cedar tree. All dishes live on a rack made of alder above the sink and drip into a tray that directs the water to the sink. Our sink is fed by a gravity-feed pipe from a small creek, and we drink delicious untreated, alive surface water. The grey water feeds our comfrey patch. A trap door in the floor leads to the root cellar used in lieu of its antiquated counterpart, the ozone depleting refrigerator. Scanning the 15' windowless north wall we first encounter the wood stove used for cooking, heating and hot water above which hang pots, pans, drying laundry, herbs and roadkill deer. In the NE corner is a stylish deco vintage shower-stall base with a retractable curtain. As we continue our circular tour, we encounter the office, complete with laptop computer and boombox. Files are neatly tucked under the stairs to the bedroom. Under the desk is a box of kindling and paper, a food box, a box of sewing supplies, a box of onions, and office supplies. In the SW corner hang bundles of garlic complete with stalks, somewhat hiding my bass guitar. The south wall is almost entirely glass and is now occupied by garden starts and trays of sunflower sprouts. The entire center of the room is uncluttered and spacious enough for 17 to dance. We are connected to the power grid but only use $3 of electricity per month and have a phone line.

Social Engineering

How can two love birds end up not killing each other while sharing a 300 sq-ft home you might ask? Think about birds sharing a nest. When the wild Earth beckons all around, why pace the corridors of a large cage? Erica and I have agreed not to talk unless eye contact is made. I don’t walk in from outdoors and say, “what are you reading” unless her eyes give that café rise, otherwise I leave her be. Psychic space is easy to give and is footprint free.   

So, how does the Straw Bale Cafe measure up?  The footprint for the straw, wood, metal, glass, plastic, electrical system, gas (for milling and delivery) and concrete was 23 times lower footprint than standard US construction on a per-person basis (EF = .112 acres for Straw Bale Cafe, 2.53 acres for standard housing).  The total cost  was $1,394.
