Want a house with timber in it, but don’t want to be responsible for another patch of trees being cut down? There are several ways to have an environmentally friendly timber house. One is to make sure you use plantation timber, which has been harvested from a forest that has been grown specifically for “sustainable” logging, rather than from native forests. Fortunately, the most common framing timber is radiata pine, which is a plantation timber. It is both readily available and cost-effective.
Another option is to source second-hand timber from a demolition yard or building recycling depot. If it can be incorporated into the design of your house, second-hand timber has more potential both aesthetically and ethically. It not only has character, with its colouration, nail holes etc, but non-renewable timbers such as Baltic or Oregon Pine, Jarrah, and Victorian Ash can often be found at a bargain price, giving you the variety without destroying any more of these valuable trees. While not exactly timber, bamboo is becoming a popular alternative, especially for flooring. It is strong and durable and unlike most hardwoods, does not shrink or swell. Bamboo is also a renewable resource, since it is a grass and will re-grow from new shoots when it is cut.
