With Expo 2025 in Osaka, Japan now officially open buildings like the Austrian pavilion are basking in the limelight. Spanning an overall area of 940m2 and serving as a ‘hub of ideas’, Austria’s pavilion includes exhibition space reflecting their role as a pioneer in ‘green technologies, sustainable architecture and digital innovation’. Source: Timberbiz, photos BWM Designers & Architects Designed by BWM Designers & Architects, the concept behind the pavilion is a musical in-terpretation of Osaka Expo’s motto – ‘Designing Future Society for Our Lives’. The idea being that in Austria, the future is not ‘designed’ but ‘composed’ providing its title ‘Composing the Future’. Sustainability was a central aspect of the overall vision of ‘prosperity, people and planet’ for the pavilion with timber playing a central part. The 16.5m high sculpture is made from PEFC-certified spruce from Austian forests and was manufactured by Graf Holztechnik. The design represents the first bars of Ludwig van Beethoven’s ‘Ode to Joy’ – the European anthem. The pavilion also employs circular economy principles. The musical staff uses ‘screws in-stead of glues’ to eliminate the use of adhesives and composite materials as far as possible and can be dismantled after Osaka Expo and reassembled. The exhibition hall is also a modular design so that can be easily moved and repurposed. The structure combines unique geometry with precision timber technology and traditional craftsmanship. “A sculptural spiral rises up into the sky – this is both an eye-catching visual beacon and the guide through the exhibition,” says Johann Moser, the pavilion’s architect from BWM De-signers & Architects. “When you get closer, you realise that it is an oversized, curling musical staff constructed from wooden slats bolted together.” The sculpture was in production for three months at the facility in Horn, Austria before being packed in sections and shipped to Japan. It uses 32m2 of timber and is designed as a ‘geodesic ribbon construction woven from indi-vidual, wooden slats’ and after bending into shape was bolted together with approx. 6,000 fully threaded screws. The design went through a series of tests, calculations and computer modelling and is de-signed around typhoon wind loads in Japan and can withstand gusts of up to 201 km/h. “With the highest precision in development and production, we have tested the limits of what is feasible and created an unlikely work of engineering from an original vision. I would like to congratulate everyone involved on this impressive success. Together, we have shown what is possible with passion and team spirit,” Stefan Graf, CEO of Leyrer + Graf said. All the national pavilions at Osaka Expo 2025 are housed within a huge giant wooden ring. The Grand Roof designed by Japanese architect Sou Fujimoto which is 20m high, with a 2km circumference, and an 8m walkway and is being hailed as one of the largest wooden structures ever built.

Amidst rising economic uncertainty, the Timber Development UK (TDUK) is exploring the impact that US tariffs and any UK Government response could have on the UK timber market. The importance of the industry staying aligned both in the UK, and globally, is essential. Source: Timberbiz The UK is currently facing 10% tariffs, while the EU is facing a rate of 20%. However, President Trump added that: “The following goods as set forth in Annex II to this order, consistent with law, shall not be subject to the ad valorem rates of duty under this order”. This is critical for the wood sector as Annex II includes the main customs codes under heading 44 for Wood and Wood products. This is perhaps not such a great surprise given that most wood and minimally traded wood products such as sawn, PAR, sanded or mouldings are globally traded on a duty-free basis and so therefore don’t meet the “reciprocal” criteria of the Trump announcement. As the UK is the second-largest net importer of wood and wood products, with an import to export ratio of 5:1 in this area, additional duty applied to USA imports is going to have a low direct impact on our sector. However, what is much less clear at the present time is the impact such additional duty may have on our customers and the manufactured products they produce, such as furniture, which includes the wood we supply. The UK government has already published a new survey “Request for input on potential UK measures in response to US tariffs.” Part of this request is an Indicative Long List of US Products that could be included in any UK measures. Dave Hopkins, CEO of Timber Development UK, says: “We are encouraging all TDUK members to read this trade note and meet the call for action to participate in the UK Government’s Survey. It is vital that the UK Government understands the impact that any potential response could have on our sector and the businesses we represent.”
