- Unique wooden dome wins award in GEPLANT+AUSGEFÜHRT architecture competition
- •ZÜBLIN Timber responsible for complex roof elements made from double-curved LENO® cross-laminated timber
ZÜBLIN Timber, the timber construction subsidiary of Ed. Züblin AG, has received an award for its Regensburg Synagogue project in the renowned GEPLANT+AUSGEFÜHRT architecture competition presented by Internationale Handwerksmesse (IHM), the construction, renovation and refurbishment fair. In 2019 the Jewish community of Regensburg inaugurated its new synagogue in the centre of the old town of Regensburg on the site of the synagogue that was destroyed in 1938. With a delicate, biaxially curved dome shell made of solid cross-laminated timber (CLT) elements, the building is not only an architectural but also a structural highlight. The use of multiply curved CLT parts is an absolute novelty. ZÜBLIN Timber, which oversaw the steel and timber construction of the dome roof from the technical side, produced 20 massive, large-format LENO® cross-laminated timber components made of cross-laminated spruce panels.
ZÜBLIN Timber was also involved as a subcontractor in the second-placed project, Roof Extension R11_Maxvorstadt, where it supplied extra-wide, geometrically complex cross-laminated timber components with high visual quality.
The annual GEPLANT+AUSGEFÜHRT competition recognises examples of successful architecture that would not be possible without craftsmanship. Each prize is awarded twice: to the architectural firm and to one of the construction contractors involved. Due to the coronavirus crisis, the award ceremony could not take place this year as usual at the IHM trade fair in Munich, but it should be rescheduled as part of the GEPLANT+AUSGEFÜHRT travelling exhibition.
LENO® is the ZÜBLIN Timber product name for cross-laminated timber. The product is typically manufactured as a flat panel and is used as a load-bearing element (wall/ceiling/roof) in residential and commercial buildings. LENO®-3D extends this conventional way of building (use of flat panels) by adding the possibility of planning and realising curved surfaces in two or three dimensions. The structural, load-bearing function of flat cross-laminated timber components remains unaffected even with LENO®-3D. The possibility of having a large variety of decorative wooden surfaces removes nearly all restrictions in terms of design. LENO® is a unique product of which ZÜBLIN Timber is currently the only manufacturer.
The advantages of LENO® at a glance:
- slim cross-sections compared to concrete
- rapid assembly times
- no formwork necessary
- significantly lower weight than concrete structures
- timber is a valuable carbon store
- modern, warm timber surfaces
