Besides the typical wood-framed home, there is a resurgence of interest in homes built like those of "yesteryear." Some examples of these homes include:
~ TIMBERFRAME HOMES
~ CORDWOOD HOMES
~ LOG CABINS
Although wood is considered a "natural product", there can be
allergic sensitivities
to various types of wood, with the biggest problems coming from the softwoods.
Because of the cost difference, softwoods are generally used for framing, while the hardwoods are reserved for inside the home - such as for flooring and furniture.
In ANY type of wood framing, the question of chemical treatment is an important one to answer. For instance, it may not be uncommon for log cabins to be heavily treated with pesticides. Are chemicals used in the chinking? If so, how much outgassing is taking place inside of the home?

Since home is where we spend a large portion of our lives, it is critical to consider the safety of that environment when building a new home. In some cases, the only option (or only affordable option) may be
standard construction materials.

In this case, you can choose the least problematic of the wood products, and be sure to have a barrier constructed between the framing materials and the living space.The tighter the building envelope, the healthier your indoor space will be.
You will want to consider spending a bit more on the materials and finishes INSIDE your home - since that is the air you will be breathing on a regular basis.
Books written from a
healthy house
perspective are more common now than ever, and you can find specific guidance to help you make the best decisions for your situation.
