Summary

There is increasing pressure on architects and builders from national and local government to reduce the impact of building and construction on the environment.

One answer is to use more wood, the most environmentally friendly commercial building material available. Wood is naturally renewable, with a significant surplus of production over harvest in Northern Europe.

Key Information

Joinery timber is used in finished product manufacture, as distinct from construction, with softwoods and hardwoods from the sustainably managed forests of Scandinavia and Europe being most commonly used in the UK. Slow growth trees, typically from the Nordic countries, provide fine-grained dense wood, ideal for conversion to a wide range of quality furniture types and components. The two main species are Pine (Pinus sylvestris), known as redwood, and Spruce (Picea abies), known as whitewood. Both species share long cell fibres and a relatively high strength-to-weight ratio. Both are easy to work, glue and nail, although Spruce has harder knots. Pine’s heartwood is a distinct reddish colour and naturally more durable than the sapwood.

Spruce’s heartwood is very similar to its sapwood, but Spruce’s overall cell structure absorbs less moisture, making it suitable for outdoor use.

Case studies

In the 1990s Oxo Tower Wharf entered a new lease of life when Coin Street Community Builders began a major refurbishment project to transform the building into an awardwinning mixed use development of co-operative homes, retail design studios, specialist shops, galleries, restaurants, cafes and bars.

In this retrofit project by Tonkin Liu, a steel-framed water tower has undergone a dramatic transformation to become a part-time residence for photographer Dennis Pedersen and his family.
