Besides looking so good, what are the advantages of a well-built cordwood home?

A cordwood home is:Environmentally friendly
It is built with materials from the environment:Softwood log ends
Sawdust Masonry Mix

A cordwood home is: Energy Efficient
Because of its large masonry thermal-mass, a cordwood home is easier to heat and easier to cool. The walls take up and “hold” the heat and slowly
radiate it back (this is called the thermal fly-wheel effect).
![Page 6: Why Cordwood?cordwoodconstruction.org/img/Why_Cordwood.pdf · Softwood log ends Sawdust Masonry Mix. ... house…your home.” ... Cordwood Construction Resources LLC Richard & Becky](https://reader031.fdocuments.in/reader031/viewer/2022030509/5ab93c6d7f8b9a684c8da906/html5/thumbnails/6.jpg)
A cordwood home is: Aesthetically pleasing.
This timber framed cordwood lodge in northern Wisconsin is a fine example of a professionally built, visually stunning cordwood home.

A cordwood home is:Economical to build
• The materials for the framework, the walls and the ceiling come from as near as the woodlot.
• Once the walls are mortared up, they are finished both inside and out.
• There is very little maintenance.• It takes time to build a cordwood home and
that extra time can be beneficial to buying materials at off-peak, sale prices.
• Many cordwood owners, build some of the home themselves.

A cordwood home:Looks like no other.
No matter how many cordwood walls are built, no two look alike.

Not many cordwood homes are completely built by professional builders, because the savings come from
doing some or most of the work oneself.
• However, here is a home built by a professional log cabin company (Frontier Log Homes in Land O’ Lakes, Wisconsin).

What does cordwood cost to build?• There are so many cost factors when building:
we have developed a rather broad cost analysis of the cost per square foot of a cordwood home.
• Some people have built for $50 @ sq. ft. • Others have reached the $100 @ sq. ft. mark and
there are many examples in between.
• Much of it depends on YOU. Can you find bargains, can you sub-contract, can you help, do you have family/friends who can help?
