Timber skyscrapers! Yes, timber has returned to prominence and even rising higher into the sky. Not all tall buildings require concrete core and steel bracing to stand tall; two or three trees will do the trick. Structural engineers are now using timber such as cross-laminated timber and glue-laminated timber to develop tall iconic buildings. Here is the list of tallest timber buildings in the world.
1. Voll Arkitekter’s Mjøstårne, Brumunddal, Norway
The 85 meter- high tower claimed the title of the tallest timber building in the world after it was completed in March 2019. Mjøstårnet was entirely built using cross-laminated timber, from the large-scale interior trusses to its elevators.
The 18-story building is made of CLT and glulam, which are strong enough to support large loads. Floor slabs and prefabricated sections were jacked up by internal scaffolding and a large crane. The local suppliers were lucky enough to supply local-sourced materials that were used to construct the ascending structure.
2. Tall Wood Residence, Vancouver, Canada
The building reached an unprecedented height of 53 meters in the summer of 2017; thus, it is the 2nd tallest timber building in the world. Tall Wood Residence was designed by the Canadian practice Acton Ostry Architects Inc. To complete the project, leading companies and consulting firms such as Fast+ Epp, GHL Consultants Ltd, and Australia-based Architekten Herman Kaufmann collaborated.
The 18-story building houses 404 students as the Brock Common Student Residence at UBC (the University of British Columbia). Prefabricated steel elements and concrete core were utilized to assist the mass timber frame. According to John Metras, Managing Director of Infrastructure Development at UBC, working with wood reduced construction timelines.
3. The Tree, Bergen, Norway
Located on Dansgardsveien, 99, Asrtad, 5058 Bergen, Hordaland, Norway, The Tree or Treet stands 49 meters tall and one of the tallest timber buildings in the world. The building was constructed in modules, the modules stacked together on site. Its load-bearing framework structure comprises glulam truss work, then a prefabricated module with a platform at the top made of a fortified concrete deck. The purpose of the concrete slabs was to give the structure the required weight.
The bb14-story building has a total of 62 apartments. After the building, the total project cost was €22M, including costs for buying the land, engineering costs, developing the concept, construction costs, and internal costs such as project management.
According to the project developers Bergen and Omegn Building Society, timber construction aided to avoid the excretion of more than 21000 metric driblets of carbon dioxide.
4. Dalston Lane, London, U.K
Standing at 33 meters high, Dalston Lane is one of the tallest timber buildings in the world. The 10-story building denoted the prospective of using timber to construct high-density buildings in the United Kingdom.
Dalston Lane is made of CLT from the first floor to the tenth floor, with core walls, through to the floors and stairs. The project was designed by a British architect, Waugh Thistleton, who indicated that timber was inexpensive and fantastic for the environment. The timber building is a short distance away from Cube, which is also 33 meters tall.
5. Forte, Melbourne, Australia
The 32 meters building, which rises over ten stories, was designed and constructed by developer Lend Lease. It is one of the tallest timber buildings in the world. The spurring structure was built within 11 months, unlocking a new era in the future for Cross Laminated Timber (CLT) constructions. In 2012, Forte was the first timber high-rise building in Australia built entirely from CLT to lower carbon dioxide emissions by more than 1400 tonnes. Forte is a residential building that comprises 759 CLT panels of European spruce, weighing a total of 485 tonnes.
