If the idea of building a strawbale house makes you think of the story of the Three Little Pigs and laugh, make sure you know the final chapter:
Everyone knows the story of the Three Little Pigs and their struggle with the Big Bad Wolf. The third Little Pig was the one who built the brick house that the wolf couldn’t blow down and became a local hero. Due to the success of his wolf-proof housing, everyone wanted a brick house, and so he opened “Mr. Pig & Sons Builders,” professional brick house builders.
They needed lots of bricks so they opened a big brick factory that made hundreds of brick every day. Finding clay to make the raw bricks was easy –it was almost everywhere– but they had to chop down a lot of trees to fuel the kilns to cook the bricks. So they also starting a logging company to chop down trees to burn in the factory. Everyone was busy and happy.
Eventually, everyone had a brick house and felt very safe. The world outside of their houses didn’t seem quite as nice as is used to be: the streams were dirty, the air seemed thicker and grayer than they remembered, and there weren’t as many trees as there used to be, but they told themselves that it was okay because everyone had a nice brick house.
Alice was the youngest child of the prosperous Third Little Pig. Alice’s family’s brick house was the finest in the town, extremely wolf-proof and handsome. It was Alice’s job to bring in the firewood and she noticed that it took a lot of wood to warm her house in the winter and that it was also uncomfortably hot in the summer. If the air was damp then the house felt damp and when the air was dry then the house felt dry.
She started to think about building her own house but wondered how to make it better. Maybe if it had more fireplaces to keep her warmer in the winter and a fan in every room to cool her down in the summer… Maybe she could install a network of tubes to move air around and make it drier or damper as needed… Or maybe there was a better way to build a house than with brick. She asked if there were any other ways to build but was told, “Brick is the best way, this is how it is done.”
But she was a stubborn and independent piggy and she began to look around for a better way of building, one that the wolf still couldn’t blow down but that worked a little better and didn’t involve quite so much mining and burning. She saw that the local farmer had lots of straw bales left over from growing wheat, and imagined what fun it would be to just stack up all those bales like big, fuzzy Legos and put a roof on and have a house! She told her father her idea.
“Don’t you remember what happened to your uncle when he built with straw?” he asked.
“This is different!” she insisted, “These are big, solid, heavy blocks, not just handfuls of straw! It will be much stronger and safer than what he built.”
“But why would you want to do something silly like that when you could build a fine brick house someday?” he asked.
But Alice was not convinced. She asked the farmer if he needed all those bales and he said he would be more than happy to give her some because there wasn’t much he could do with them. He said that he even sometimes had to burn the extra straw to get rid of it, which he didn’t like to do because it made the air thick and black for days.
She did some research and found that she was not the first to think about building with bales. The American settlers who arrived on the plains of Nebraska had very few trees or even rocks to build with but they did have horse-powered baling machines and a lot of grass, so they made shelters out of bales of grass. These buildings were meant to be temporary, just to get them through the harsh winter, but some of them were so cozy that they became permanent. She was amazed to find that some of these buildings had survived for over a hundred years!
While doing this research, she heard about a few modern pioneers living out in the desert who had been experimenting with building with bales. So she went and visited them. She stayed in a tiny strawbale house that other students had helped to build and fell in love with the not-quite-flat, not-quite-square quiet coziness of it. She stayed and helped them build more buildings and, in return, they were generous with their knowledge and she learned a great deal. She learned it was not quite as simple as just stacking up the bales: that strawbale houses need a good pair of boots (foundation) and a good hat (roof) and a good coat (plaster). She also realized that she needed to know enough about all of the other systems –like plumbing and electricity– that go into building any house.
She came back to her hometown full of inspiration and confidence. She bought a little piece of land near her father’s house and told him she planned to build her own strawbale house. He smiled and wished her luck but told her that, because of his reputation and something called “professional liability,” he couldn’t help her with her project. He quietly drew up plans for a nice brick house to build for her when she gave up on this silly straw idea.
At first, Alice would go to her piece of land and just sit and look. She watched how the sun moved across the land and noticed where the wind came from. Once she knew her land, she planned a house that fit with the sun and the wind and the land and she began to build. When the word got out about her project, the neighbors began dropping by with questions.
“Won’t the horses and goats try to eat your straw house?” a neighbor asked.
“That’s the difference between hay and straw: hay still has seeds but straw is just the stem of the plant with all the food removed. There will be nothing for them to eat in my walls,” Alice said as she began to dig for the foundation.
“What if the wolf tries to burn it down when he can’t blow it down?” another neighbor asked.
“Once I have the plaster on, I’ll be safe. The plaster doesn’t let the air or the fire get to the bales, which makes the house very fire safe,” she replied, as she built the sturdy frame for her house. “And even if the fire somehow got through the plaster, the bales are dense like a phone book and do not burn well. I’ll have time to pack my bags while he’s trying to get the house to burn.”
“It’s just straw, won’t it rot and fall apart like the straw bale I left in my garden last year?” asked a friend.
“Wood will rot if you leave it out in the garden. Almost anything will rot if you don’t protect it. I will give my house a good roof with wide overhangs and a thick coat of plaster and then it will not rot,” she answered while framing the roof. “In fact, the walls of my house will breathe and won’t ever grown mold.”
“Won’t mice crawl into your walls to make nests like they do in the stacks of bales in my barn?” asked the farmer.
“They are such nice, dense bales you made and I am stacking them so tightly together that there won’t be any space for a mouse’s nest,” she said while she waterproofed her roof. “When they can’t get into my solid walls, they will go back to living in your barn.”
When she had finished building the sturdy foundation and frame, and finished the roof so she would have a dry place to work, she went out to the farm and chose the farmer’s nicest, driest bales.
She cut the bales carefully to fit snugly around the frame. She cut channels into the straw and hired an electrician to run the electrical wires. She filled the channels and any small holes with cob, a mix made of the clay she found while digging the foundation and straw leftover from cutting bales. Then she mixed up a big batch of clay plaster and plastered the bale walls inside and out. It was hard work but she loved the smell of the straw and the feel of the clay.
The house she made was not the biggest or the fanciest but it was nice and it worked well: it was warm in the winter and cool in the summer. In the winter, the low sun ducked down to kiss her windows and warm the floor and walls of the house. When she built a small fire in her fireplace, it quickly warmed the whole house and the thick, snug walls held in the precious heat.
In summer, she could open her windows and collect the cool evening breeze, then close the windows and keep that coolness through the next day. The hot, high summer sun couldn’t reach under the wide roof overhangs, leaving her house in the cool shade.
The clay on the walls breathed in extra moisture, making the humid days less humid and exhaled the moisture back out on dry winter days. She never saw droplets of moisture on the inside of her windows like she had in the brick house where she grew up. She loved her quiet, not-dead-flat, not-dead-square strawbale house and also loved how little mining and burning had gone into it.
One day a wolf came to town. The town hadn’t seen wolves in years because all of the houses were brick and the wolves knew they couldn’t blow them down. This wolf had heard that there was a new house that wasn’t brick and he thought he might have a chance.
He approached Alice’s house and yelled, “Little pig, little pig, let me in!” Nothing happened. He yelled louder, “I’ll huff and I’ll puff and I’ll blow your house down!”
An upstairs window opened and Alice leaned out. “Oh, I’m sorry, I couldn’t hear you inside my strawbale house. What did you say?”
Angry and a little self-conscious, the wolf shouted “You know the drill! Let me in or I’ll wreck your nice house!”
“No,” she said and shut the window.
The wolf took a huge breath and blew as hard as he could, but nothing happened. Then he backed up, ran as fast as he could and slammed into the wall. He bounced off with a bone-shaking thud but the wall was fine. By this time, all of the neighbors were watching from their windows, concerned about Alice in her strawbale house. The wolf got mad and decided to burn the house down. He gathered some sticks and paper and lit a fire right next to the wall. The fire sent black smoke up while the sticks burned and then it just went out. Other than being a little bit sooty, the wall was fine. Discouraged and embarrassed, the wolf gave up. “That house is just as strong as a brick house,” he muttered as he walked away.
That evening, the town had a huge feast to celebrate another wolf defeat and Alice got her picture in the local paper along with an article about her strawbale house.
One by one, her neighbors began to see what Alice loved about her house and started to wonder if someday they might be able to have one of their own instead of an uncomfortable, dead-flat, dead-square brick house. Alice’s father started to get requests and asked her if she would help his company learn to build strawbale houses and she happily agreed. But she did have one suggestion: “How about we rename the company Ms. Pig & Father & Brothers Builders?” she said with a twinkle in her eye. Her father met her halfway and “Pig Family Builders” began to build lovely strawbale homes for everyone who wanted one.
With less demand for brick, the brick factory started making solar panels as well as bricks and the logging company started to plant as many trees as they cut down. Slowly, the streams and the air cleared up and the world became as nice as it used to be. And the wolves, who realized they’d never be able to catch the pigs, developed a taste for tofu instead.
