Wherever possible, our homes use timber in preference over other building materials.

Timber plantations are a carbon-dioxide (CO²) sink.  A CO² sink is a carbon reservoir that is increasing in size, the opposite of a carbon "source".  Modern power stations and cars burn fossil fuels and emit CO² and are a source of CO². Plants and trees take this CO² into their leaves and through photosynethis convert it to oxygen (O²).

Timber used in construction is renewable, as more timber is grown as the mature trees are harvested. Pine plantations are also sustainable, as the trees require very little cultivation after planting.
