Wood Frame Construction

I generally discourage people from building with wood because our forests world-wide have been so badly decimated by over-harvesting trees and it is becoming more critical to maintain our forests, not only to preserve their ecosystems but to help sequester all of the CO2 that is floating in our air. However, building with wood (at least partially) can still be a sound ecological choice, which is particularly true in regions where forests have regenerated to the point that they can be harvested sustainably. This means that the trees are carefully monitored to make sure that the health and character of the forest is maintained; only certain trees are culled periodically, leaving the remaining trees to grow and contribute to a healthy ecosystem. It is possible to buy wood that has been certified by the Forest Stewardship Council (FSC), but if this means that you are buying wood shipped great distances, then this becomes a less ecological choice; use local materials!

Timber framing, or post and beam, and pole construction

are all ancient methods of providing a rigid framework for constructing buildings. Pole building usually refers to actually planting poles in the ground to secure the structure and provide the foundation, whereas timber framing and post and beam construction require a separate foundation. Because of the difficulty of preserving wooden poles that are sunk into the ground over time, this method is most often reserved for what might be considered temporary or agricultural use, such as for barns or sheds.

With a minimum of heavy-duty timbers, beams, posts, this technique can create strong and versatile load-bearing structures, which can then be completed by either in-filling between the wooden structural members, or completely wrapping them with a variety of other materials. Since this method of building has been recognized and approved by most code authorities, it is a way of approaching a natural building project that would otherwise be difficult for the authorities to sanction.

The Larsen Truss System

for the construction of super-insulated homes was developed by John Larsen, a builder from Canada, as a means of improving insulation levels in existing houses. The trusses generally have a two-by-four stud which is joined to a two-by-two stud positioned in spaced parallel relation to the first stud to form a twelve inch wide insulation cavity. The two studs are spaced by spacers and are rigidly supported by diagonal cross braces. The wall trusses can be manufactured with the same equipment as utilized in the construction of floor and rafter trusses formed of dimensional two-by-fours. The ability to shop-fabricate the wall trusses using truss plates means that engineered truss members for each job can be supplied, thereby minimizing material utilized while at the same time saving considerable labor over on-site construction.
