Even though I’m busy building my own little house, I still find myself thinking of making Cob House Plans . I have returned to the cob house again and again because I like the curves of the cob walls, the organic feeling brought by the cob mixture and the price is also very attractive. I have been thinking of building a cob house if in the future I decide I need more space if I’m married or just want more space.
What do you know about Cob?
Cob is clay, sand, and usually, straw mixed to be used as a building material, rather like bricks, but the advantage is that most of the material can be sourced on-site or bought cheaply. Having the right ratio of these three ingredients will allow you to make a studied mixture. It’s basically like a mud palace for adults, it’s a building technique that has been used for more than 10,000 years!
Why A Cob House Plans ?
A Cob House Plans is a natural building material that has many useful properties suitable for a very comfortable home. With the thick walls of a cob house, you have a lot of thermal regulation happening. So in summer, the walls make everything cooler. In winter, walls can carry heat until late at night.
The cob lasts a long time
Cob is also very durable if protected from the rain. A good roof will protect the walls and last for hundreds of years. Even when the house has begun to weather, you can reapply a new layer of cob to the outside to make it new!
Affordable Cob Housing
Cob is also very affordable, in many cases, all materials can be found on your land or can be obtained in large quantities at fairly cheap prices. You should do a soil test on your soil to see if it is suitable for building a cob, but in general, most sites have usable land.
Cob House Plans Pretty Fire Resistant
Because it’s mostly clay and sand, you don’t have much to burn the forest. Tuna is a popular choice for areas prone to wildfires or other extreme weather.
Healthy Cob House
Making a cob house often creates a very healthy home for air quality. One area that you need to pay attention to is the humidity level. After you make the cob, it needs to be completely dry and can take months to years. Most of the moisture will dry up on the wall in the first year, but it will not fully heal for 1-2 years.
After you build a house and add a roof, you have to let it breathe for months before moving into it. Then I will carry out your internal sealing process. When you are completely moved, a dehumidifier will be important to draw large amounts of moisture out of the air.
Curved Walls And Cob Round Houses
The thing that I like most about the cob house is the arch of the wall. There is something very comfortable, very interesting, very entertaining about the curve of the cob house. You can have organic forms that allow the elements to flow with each other. It’s hard to put your finger on what it is about the cob house, but they have magical qualities that seem to resonate with some part of our brain.
How Do You Mix Cobs?
The important part of the cob is getting the right mix, you want about 2 parts clay, 1 part sand, a sprinkling of straw and a little water. To mix this, the favorite method is with your bare feet! I love the feeling of a cob sandwiched between your toes, so much fun! You want the ingredients to be very well mixed, moist, but not wet and the straw works well.
The mixture must hold its shape firmly and not look like it is melting or degenerating. Make a brick test set and allow it to dry.
Building a Cob House
Cob House has many benefits, one side is very labor-intensive and takes a long time. Unlike traditional houses that can get up very quickly, COB is a slow process, so be prepared.
Set a Foundation for Your Cob House
There is no good house without a solid foundation to build on and it goes double for COB. Because your cob wall is very thick, about 24 inches thick, we are talking about a lot of weight. Thousands of pounds weighing from the wall alone. We want to have a clear and good site for building houses.
Start by cleaning the topsoil to get to the solid subsoil. You want to dig down below your ice line which can be 2-3 feet in some areas. From there build your base with quality materials and lower it with powerful tamper as you build your path.
Consider the flow of water, so that water will be channeled from the location of the house and any water that comes into the house can flow quickly. Use French drains and swales to handle this water.
Build Your Cob Wall
The walls in the cob house are very thick, which gives strength. Your walls will be thicker at the base and become thinner as they rise. At the top, your wall might be about 18 inches, but the wall of your cob at the base will be 24 inches. As you build, stab a hole in the top of the wall to allow you to integrate the next layer into the bottom layer.
In general, you can only build walls 2-3 feet vertically at a time before you want to let them dry and dry them. This is an important step and takes a long time with cob. Allowing it to dry will ensure the wall does not sag.
Windows and Doors at the Cob House Plans
You really can have windows and doors in a cob house. The main approach here is to have a solid wood action as a header for the top span of the window or door. It has a large piece of wood that is at least 6 inches thick and goes as wide as a wall.
You want the crown to pass through the opening gap and then spread at least one foot on both sides so that it rests firmly on the wall, moving the weight to the wall. The greater the range, the greater you need to extend your header to be supported by a wall.
