The cob walls are complete

By Cob Building

194.5 batches of cob stomped by foot and applied by hand and you get:

100percentcobwalls

Yesterday afternoon and this morning, I put some final touches on the cob walls, leveling them in preparation for the soon-coming reciprocal roof. After I smoothed out some of the last cobs, I took a minute as I stood on the lean-to trestle, just staring down at the walls which now easily tower over my head, and I wondered in amazement.

It has been quite a journey to this point, moving over 40 tons of material. That’s a lot of earth. More specifically, it’s been 194.5 batches of cob so far. All this over 57 days (which were not all full work days, mind you.)

And it’s not over yet, but this massive portion of the process is, at least. Here are some photos of the structure.

Cob walls are 99%

By Cob Building

Here’s a couple of photos of the 99% complete cob walls. I figure I’ll be able to finish them off tomorrow, perhaps Sunday if it takes a couple more batches than I expect. Reciprocal roof: here we come!

Also, in the top photo you might notice a post near the entryway. This black locust post will bear one of the reciprocal roof rafters, making for a nice little overhang near the entryway. Call it a really small porch, maybe, but this should provide some decent extra coverage from the elements.

The end is (seriously) near

By Cob Building

With the help of my superstar work exchangers Dan and Danielle, the cob walls are nearly complete. Unfortunately, D&D departed today to begin their own pursuits, but I am hopeful that I’ll be able to complete cobbing by myself by the weekend. I suspect it will take 10 or so batches to level out the walls in preparation for the reciprocal roof – no problem! (My estimations are historically inaccurate, but I feel pretty confident about this one.)

It’s amazing how tall the west wall (see above) is/feels, compared to the rest of the house. A little bit of slope can go a long way.

Last night we had a third campfire in the house, and several folks have suggested leaving the house as is, without roof, because of the dramatic light cast by the fire on the walls. It’s quite a sight. Maybe I’ll have to design a retractable roof…

The story so far

By Cob Building

cobhouse-nw01

Recent highlights the past week included cobbing above the south window, removing the door brace (ahhh for easy entering and exiting!), and sticking in most of the deadmen for the roof rafters. It feels more and more like an actual house with each passing day.

Moonlight cobbing

By Cob Building

cobcampfire

This weekend, I had a strong urge to do some cobbing after dinner, during the sunset hours. So, last night we (myself and Dan and Danielle [my two work exchangers], later joined by Liat) ate dinner and stomped a batch of cob as the sun went down. By the time we were done stomping, it was super dark and pretty dang difficult to actually get the cob on the walls, but we managed.

After that first batch of cob, we figured it would be a good idea to make a campfire inside of the house. Ted and I set one up, and the house glowed like a giant woodstove. It looked great from the road, with a bright orange aura.

There was a full moon that cast a great light on the walls as it rose towards the sky later that night.

Fun stuff.

Installing shelf joists in cob and inching closer to the roof

By Cob Shelves, Cob Building

(Satisfied after today’s good progress – See the new cob at the top of the wall there?)

With help from my most enjoyable new work exchangers Dan and Danielle, I am inching closer and closer to the roof of my cob house. Today marked the completion of one of the few remaining and more challenging elements before that happens, though — installing joists for a wide shelf positioned above the (future) cob bed.

shelf-joist

Yesterday, we built a joist rig with some 2×4s that could be buried in the cob: three 38? long joists attached to one long 2×4 banged out with lots of nails. This whole thing was placed on the cob wall and leveled, joists braced, and then cobbed in place. Hopefully the joists will be strong, as they are buired in all 16? of the cob wall. The shelf will be 22? wide and 7.5? long and will mostly be for storage.

Time will tell whether or not the joists are buried in enough wall to support the weight of potential clutter on the shelf. I am hopeful!

Installing lintels above windows

By Cob Building, Lintels

The past week has been extremely productive, thanks to some help from Apple and a few other folks from Sandhill Farm. The cob walls are nearing 85% complete, I’d say. But before I finish them, there are other things to take care of, too. Namely, I need to install lintels above my windows and doorway, and start preparing for the roof.

Lintels are lengths of material (usually, slab wood, pole wood, milled lumber, bamboo, etc.) used to span window frames in natural buildings. They help to bear and spread the weight of the material (cob, in my case) above windows and doorways. Depending on the material, they can be pretty decorative, too.

I cut some osage orange wood for my smaller window lintels, leaving the bark intact for a more ‘raw’ look. I’m pretty happy with the effect.

For my large south-facing window (see top photo), I chose to use some pole wood that I got from Skyhouse. I wanted something straight and easy to work with, but also round, so these fit the bill. These lintels are shorter than is ideal (they only overhang the window by six inches on both sides), but hopefully they will still get the job done.

I am just now starting to think about how the rafters of my reciprocal roof will be placed on the walls, so these next few days will be heavier on the “thinking work” side of things…

Another cob house picture update

By Cob Building

The house is starting to feel much more like an actual house now that some of the walls are 6+ feet tall. Standing inside, it’s also easier to imagine what the final house will look like, where things will go, and how big the space feels.

Sculpting with cob

By Cob Building, Cob Shelves

entry-shelf00

If there’s one thing you’ve probably heard/read about cob many times before, it’s probably the fact that cob is immensely sculptural.

Lately, I have been working at a much slower pace since I have been working on sculpting various cob book shelves and other little storage nooks into the walls of my house. The photo above is a small shelf immediately next to the entrance. When I look at it now, I think of the mouth of a snake or the jaw of some other creature.

bookshelf00

This wide bookshelf extends almost a foot from the wall, and is nearly 18″ at its peak height in the center. The shape is pretty strange and not exactly what I intended to sculpt, but I kinda like it now that it is done. (I can always do a little bit of carving with a machete if I decide to alter the appearance.) I will build a similarly-sized shelf right above this one.

mushroom-window-ext01 mushroom-window-int00

This mushroom-shaped window came to me in a something like a vision the morning before I started to work. I acted upon the impulse and stuck a piece of sheet glass in the wall and began to sculpt around the glass to make something roughly mushroom-like. I’m pretty satisfied with the end result. It will look much cleaner once the walls are plastered, I think.

coathooks00

I carved these coat hooks from some mulberry wood and planted them in some fresh cob this afternoon. I mostly just cut the wood to size, whittled it down a bit, and smoothed it out. These are located right near the entrance for jackets and other things for hanging. I hope these hooks give the effect that they growing out of the wall once it’s all said and done.

Three feet and rising

By Cob Building

cobhouse01

Ok, so my original estimate of 100 total batches of cob to complete the walls may have been off.

Eighty plus batches later, the walls stand at an average height of 3.5′ (not including the foundation), which is probably half the total amount of cob necessary. Some taller spots are now no longer workable without standing on a bench (as seen in the areas next to the south window in the photo above.)

Now begins the time when the actual cob application slows down, due to the extra step of having to stand on and move a bench or scaffolding (which I might just need to make soon…) to work the walls.

We didn’t get nearly the same amount of work done this week thanks the absurd amount of rain, but I guess a little break is an okay thing, too…
