It has now been a little over 2 weeks since we arrived in Ecuador. It's quite hard to believe. We've had so many incredible experiences already and have learned so much that it feels like we've been here about 2 months!
I decided I'd greet you with the view we have out our window every morning. :) This morning was unique in the fact that Volcano Pichincha and its neighbors were covered in snow. Typically the snow melts by early afternoon but this time it happened to last nearly all day.
In addition to working the garden we have had the awesome experience of helping a neighbor build his earthen house. Now, I don't know about you, but when I think of an "earthen house" I think of some sort of sweet underground tunneling system (which we have witnessed here by the way) or something built with adobe or earthen bricks like you see below.
The technique I'm about to show you is nothing like what you see here. Be ready to be amazed!!

THE COB HOUSE
Now to preface this, I should start by saying that I am not an expert at building with cob and everything you see below is from my recent personal research and experiences ONLY. Although I've learned an incredible amount in such a short amount of time, I have a TON more to learn before I'm any sort of an expert. So here we go...
Cob - True cob is a mixture of earth, sand, water and straw. It is mixed to a consistency that makes it easy to pile up and sticks together nicely, which makes it quite convenient for building walls.
Here are some of the ADVANTAGES of a cob house:
- Inexpensive - Mainly because you're using earth found right on your property
- Fire PROOF - There have been recorded forest fires where the only standing houses were of cob
- Heating - Cob retains heat extremely well (and stays cool in the summer)
- Architecture - It gives you unlimited options for the shape of the house and allows you to sculpt and bend the walls in beautiful ways
- FUN! - It's like sculpting your own house out of clay, lets you work with the earth and with your hands, and encourages teamwork and collaboration. Best of all, you can't really screw it up!

Here it is step by step how to build a house with cob!
STEP 1: Mix the Cob
First make a mud pit by mixing water and earth.
Next, throw on some rubber boots and JUMP in it!
Toss in some straw to give the mud better structure for building.
Lastly, run around to mix it well (if you can). The cob mixture is ready to use for building when your boots nearly get sucked off in the thick, sticky mud. It is SO FUN and also an amazing WORKOUT!
STEP 2: Haul mud
When the mixture is ready, you scoop it into buckets with a shovel.
Here's my bucket - I know it looks tiny, but let me tell you this stuff is incredibly heavy, especially after about 50 trips to the building site!
Next we got to haul the mud from outside to the building site.
For us this meant walking up to the second story on a homeade "ladder" of sorts, balancing on the log which you see to the right, and hoisting the bucket onto the boards that are on the second story.
Once on the boards, walk very carefully, balancing with the heavy bucket...
...Don't look down!!...
...until you arrive at the far wall...
...then sit down and exhale...
...because you made it (this time). Only 49 more trips to go for the day!
STEP 3: Pack mud
Glob by glob, plop the muddy mixture into the wall and pack it well.
This style of building is called 'barregue' (pardon the spelling) where you first build the structure of the house with wood slits and then fill them with mud. True 'cob' is built without the wooden cross supports that you see here. A 100% cob wall needs to be thicker to have a solid structure but it uses less wood, which is better if your goal is using local materials.
Pack and pack until the wall is smooth and complete. Notice the "stained glass" window made out of glass bottles found behind Brent, just another way that the builders use recycled materials.
STEP 4: Let Mud Dry
The next step is pretty tough. Sit back and wait for the mud to dry. Everything that is dark grey in the picture is what Brent and I completed during our first day of work. 2 people x 6 hours = a partial wall of 1 bedroom completed. Clearly building with cob is relatively time intensive, but it's rewarding work.
STEP 5: Cover and Smooth
After all the barregue walls are filled in with mud and they have dried, another layer of cob is applied to smooth everything out. Here's the expert homebuilder himself. They call him "El maestro." He is the brains behind this operation, and he also built the house where we're currently living.
STEP 6: Paint with Water
I love this picture, because it essentially shows steps #4, #5, and #6 together. On the right is the barregue, dried and ready. On the left (bottom) is the smoothed layer of cob, still wet. On the left (top) is the extra smooth layer of this same cob after it has been painted with plain old water. After this stage the house is finished!
Here's the house where we left it. You can see it's still a work in progress, but it's definitely starting to take form!
STEP 7: Paint
After the house is completely done, the finishing touches are added. The "paint" used for the house is actually tinted dirt that comes from the Amazon. The house we were building had about 5 different colors to choose from. The house we're living in used natural colors, that you see below.
A redish pigment used for the outside of the house (p.s. this is what the walls of the other house will look like when they're finished).
The lighter tanish color used for the inside of the house. The beautiful tree sculpted on the wall was done by a volunteer like us. :)
STEP 8: Descansa!
I almost forgot the most important part. Descansa (rest)!
As hard as these guys work, they sure know how to enjoy a break. Friday breaks are extra special, as the cerveza is passed around and enjoyed by all...during the morning break, during the post-lunch break, during the afternoon work (which technically is not a break), during the post-work break...you get the idea. :)
After a lovely week of building, I leave you with the view from our in our cozy little cob bedroom at sunset.
Who knows, maybe you'll be visiting us in our own hand-sculpted cob home someday. :)
