Most trendy timber towers, just like the 230 Royal York and Ascent, function a concrete core for stability. Nonetheless, the Fyrtornet workplace tower by Wingårdhs rises to a powerful peak of 51.5 m (169 ft) with out the necessity for concrete, highlighting the sustainable prospects of timber building.
Fyrtornet (Swedish for “lighthouse”) is situated in Malmö, Sweden. Structurally, it consists of glulam (glued laminated timber) beams and diagonals, and CLT (cross-laminated timber) flooring slabs. Its core, which supplies structural integrity and homes the steps, can also be constituted of CLT. Some concrete was used within the construct, although solely within the foundations.
The facade combines wooden that has been painted pink, spruce shingles, and glazing with built-in photo voltaic panels, serving to to scale back its draw on the grid.
The constructing was largely prefabricated elsewhere in Austria, and prepare transportation was used to decrease CO2 emissions. Moreover, a big tent was erected on-site and use to fabricate the partition partitions domestically, additional decreasing CO2 emissions.
“Due to the usage of rail as a substitute of the traditional truck supply, we have been capable of save 100 tons of carbon emissions,” explains engineering agency Binderholz, which was concerned in constructing the mission. “A significant benefit of rail supply lies within the storage areas that native prepare stations supply. This manner, the delivered materials may be briefly saved in a cheap method and the development web site can then be repeatedly equipped with timber building elements, making certain trouble-free meeting.”

Inside, Fyrtornet measures 9,020 sq m (roughly 97,000 sq ft), throughout 11 ranges. A café, bakery, and bistro occupy the bottom flooring, with a library straight above. The higher flooring host workplace area, whereas a rooftop backyard crowns the constructing. The inside decor correctly highlights the pure heat of uncovered timber, moderately than protecting it up.
Hearth is all the time a priority for some individuals in tall timber buildings, however trendy timber isn’t like old style wood framing. The glulam and CLT used on this mission include many layers of wooden glued collectively to kind a far stronger wood beam that may even outperform metal in a hearth. It’s because the fashionable timber chars slowly on the skin moderately than totally igniting, which helps to protect structural integrity.
