It is exciting times for tall wooden buildings in today’s cities. City population growth, space availability and infrastructure pressures are contributing to the need for innovative building solutions. An aspect of this direction that takes advantage of timber’s dexterity as a building material and environmental credentials is the development of a new generation of super strong engineered timber products.

Besides its popular appeal, and lightness making it suitable for construction in densely built city centres, the range of other environmental benefits for building in wood are substantial. There are significant carbon dioxide savings to be made by using timber in the construction of houses and other buildings, both in terms of embodied energy and in-use energy efficiency, and associated greenhouse gas emission reductions.

Changes to the National Construction Code (NCC) provide ‘Deemed-toSatisfy’ solutions for timber buildings up to eight storeys, or 25 metres to be constructed. Timber can also offer quicker build times, with less noise and disruption. Timber can also offer innovative design approaches that apply to both traditional light weight timber framing and innovative massive timber systems, such as cross laminated timber (CLT).
