Yakisugi: Japanese Charred Wood Finish

By Carpentry, Timber Framing, Woodworking

shou sugi ban finish with propane torch

Yakisugi is a traditional method of wood preservation. Charring wood is not specific to Japan, but charring sugi (Japanese cypress) for cladding use is a traditional feature of some Japanese architecture. It’s been used primarily for practical reasons — charred wood is less susceptible to rot and moisture damage, insect damage, and ironically enough, it’s more resistant to fire. Plus, it looks pretty badass if you ask me.

I first saw a video of a guy burning sugi boards several years ago and was entranced. I knew that I wanted to try it sometime, and I decided to use our first timber frame as an experiment. So I bought a torch and lit up our white oak timbers. Read ahead for more…

Clay Plaster Benefits

The Unique & Beneficial Properties of Clay Plaster

Clay Plaster Benefits

Clay soil is one of the most ancient, rudimentary, yet effective building materials on the planet. Besides being naturally abundant across much of the earth, clay has unique properties that make it not only suitable but very desirable as a natural building material. Clay is used for the production of fired brick, sun-baked adobes, cob, and natural plaster finishes.

In this very basic introduction to clay soil, I will highlight some of the unique water-loving features and other useful attributes of clay when it’s used as a natural building material, particularly as a plaster finish.

If you’re new to natural building, two of the most important fundamental concepts to understand are thermal mass and insulation. Materials for constructing walls typically fall into one category or the other. Understanding the differences will be critical if your goal is to build an efficient, comfortable house appropriate for your local climate. Let’s look at thermal mass and insulation in the simplest terms possible.

Introduction to Installing Earthen Floors

By Resources, Earthen Floor

Installing the base layer of an earthen floor

Earthen floors are floors composed of compacted clay, sand, and straw. They are made flat and troweled smooth just like a concrete slab. However, the finished product is much softer on your feet… and on the earth itself. You can build an earthen floor with readily available materials. The labor input is quite high, but the material cost should be very low. And of course, the embodied energy is low, too — this is a very resilient, low tech method that can be incorporated in a variety of locales. Here’s a very short introduction and answers to common questions about earthen floors.

A Light Clay Straw Building Primer

By Light Clay Straw, Resources

stuffing-slipstraw-in-wall-cavityIt’s been quite the eventful September. The big news of the month is that we hosted our first Natural Building Workshop at the homestead. It was, in a word, wonderful. We had a very diverse group of 10 folks come out to learn all about cob, light clay straw, clay plaster, and clay paint. I couldn’t have asked for a better group. I’m continually amazed at the positive energy that is generated through these workshop experiences.

One of our projects was building the light clay straw walls of our new outhouse, which I’d like to document a bit here. This is an outhouse that will serve future workshops and large events (as well as being quite useful for just ourselves, too). The building is also a little bit of a “natural building showcase”, as it will have a few different types of natural finishes on display when all is said and done.

Read ahead to learn about how to build a light clay straw wall.

Essential Timber Framing Tools

Timber framing tools

This list should help you get started down the path of timber framing with hand tools

Like any craft, the world of timber framing comes with its own unique set of tools. And if you’re new to this type of work, it’s important to have the right timber framing tools in your kit. Thankfully, it doesn’t have to cost a small fortune to equip yourself with the basics. Of course, once you get deeper into this kind of stuff, you’ll always find something else you think you probably need. But for a solid starter kit, you can get by with a relatively small handful.

I’ve narrowed down a list of essential timber framing tools, highlighting both inexpensive options for folks starting out, and more expensive choices for someone who may continue with this line of work.

p.s. Did you know we host Timber Frame Workshops every year? You can try all of these tools out and more…! Read More

How to Mix the Perfect Batch of Cob

Building With Cob

Stomping a batch of cob on a recycled lumber tarp

In the seven years I’ve run The Year of Mud and written about building with cob, I realize I haven’t written a simple ‘how to mix cob’ post. For many folks, particularly anyone coming across my various cob oven articles online, it may not actually be obvious how you mix cob, whether it’s for an oven, bench, building a house, etc. So, better late than never — here is a handy reference if you want to mix the perfect batch of cob for your project!

How to Build a Better Outdoor Pizza Oven

Build a Better Outdoor Pizza Oven

Learn how to build this outdoor oven in this new how-to

Several years ago, I wrote about how to build (the now-infamous) $20 outdoor cob oven. That oven I built worked decently, produced a lot of delicious meals, and advanced my pizza baking fever to new heights. Since then, we’ve built several more outdoor pizza ovens, and each of them has been a great improvement upon the original.

This newer model is slightly bigger, allowing for easier access to the oven interior, it has even more food baking potential, and the insulation is vastly superior. This sucker gets hot, and stays hot… for a long, long time. The oven has a small roof shelter, protecting it against the weather, and a chimney keeps smoke out of the face of the fire tender. Best of all… the oven is still very inexpensive to build.

This is a very achievable, low cost, and effective oven that will not cost you thousands of dollars to build. Here’s a look at the new and improved outdoor pizza oven plans and how you can build your own.

Cob Building is Not Appropriate For This Cold Climate

By Moisture, Winter, Heating

Cob House Cold Climate

There’s something I’ve had to come to terms with living in our cob house, Gobcobatron. Cob is not the most appropriate, responsible building material for this cold climate of northeastern Missouri. This applies to similarly cold climates as well. Sad to say, but that is the reality.

Here are my thoughts on why cob building is not appropriate for cold climates, based on personal experiences and understanding more about the thermal properties of cob.
