Birch base for Future Africa campus The new Future Africa campus of the University of Pretoria was built to provide Africa’s leading researchers with a place to work in multidisciplinary co-operation and to seek answers to the problems that the continent faces. Designing the campus posed a challenge for the award-winning architect André Eksteen . The architecture was to have a positive impact on both human minds and the environment, and local resources were to be prioritised during construction. The solution was wood. Eksteen designed the conference centre, research facilities, cafeteria and housing units as “jigsaw puzzles.” The pieces were prepared in advance and assembled on site. UPM’s WISA birch plywood formed the basis of the design. WISA birch plywood was used in the frame, wall panels, furniture, doors and ceilings. Concrete jungle to skyscraper forest UPM’s long-standing Japanese partner Sumimoto Forestry aims to build a 350-metre skyscraper predominantly of wood by 2041. The building will celebrate the 350th anniversary of the 1691-founded corporation. The W350 project is part of Sumimoto’s broader vision of a future city blending with forests and nature through increased timber construction.

THE 55-KILOMETRE Hong Kong–Zhuhai–Macao Bridge is the world’s longest sea-crossing bridge combining cable- stayed bridges, an undersea tunnel and artificial islands.

With the U-Build concept, Studio Bark aims to change how people perceive construction. The innovative method provides a means of creating affordable buildings that adapt to the changing needs of their users. All of the materials are sustainable, non-toxic and made from natural resources. The method has already been used to build various storage and work spaces, as well as the Box House project, which was featured on an episode of the UK television programme Grand Designs. Another Box House project was exhibited at Grand Designs Live in London in spring 2019, where the public had the chance to take part in building the house by adding their own modular sections. The building components used at the exhibition were made of UPM’s WISA plywood. The architects were happy with the positive reactions from the participants: “We were delightfully received by people who want to build houses or garden sheds, for example. We received enquiries from all around the world.” Plywood gives shape to world’s longest bridge The 55-kilometre sea-crossing bridge that connects Hong Kong, Macau and Zhuhai is an impressive combination of cable-stayed bridges, an undersea tunnel and artificial islands. The bridge, which was opened to traffic last year, reduces the travel time from mainland China to Hong Kong from several hours to just 30 minutes by road. The bridge is part of China’s aim to transform the Pearl River estuary into an economic region comparable to the bay areas of San Francisco, New York and Tokyo. Although the bridge is mainly made of steel and concrete to endure even the harshest conditions, wood also played a key role in its construction. For example, the tall tunnel openings and the massive breakwaters around the artificial islands were built using plywood shuttering forms. Plywood is highly suitable for shuttering forms because it is a sturdy and light material. It is essential that the forms do not bend when the concrete is laid. Depending on its coating, the same sheet of plywood can be re-used over 100 times, making it both sustainable and cost effective.

Sumimoto Forestry plans for 90% of the materials used in W350 to be wooden and the remaining 10% to be steel. To create a warm, peaceful atmosphere, the interior of the 70-storey building will consist wholly of Japanese larch. The building is estimated to store up to 100,000 tons of CO 2 . The Japanese corporation has conducted simulation tests and is certain that W350 will be earthquake-proof, however the building’s fire safety features still require some work. “To realise the project, we need to collect results from research and technological development together with our many partners. We are working together to develop and look into construction methods,

wood utilisation, urban green spaces, sustainability and the benefits of digitalisation.”

Anyone can U-Build Sustainable, natural, modular, flexible and cost-effective: this is the U-Build system developed by the London-based architecture firm Studio Bark. The system of interlocking boxes lends itself to convenient on-site construction of spaces, walls and furniture of various sizes and shapes. The only tools you need are a hammer and a drill.
