New CTBUH study on tall mass timber gives us a look at the impacts of the material industry-wide

2022-05-26T13:37:00-04:00

A new study from the Council on Tall Buildings and Urban Habitat (CTBUH) has revealed important statistics that provide a clearer picture of the present state of tall mass timber construction across the globe.

There are now a total of 66 completed mass timber projects worldwide totaling of least 8 stories or higher. Nearly two-thirds (64% or 54 buildings) of all projects are residential, while office buildings account for 19% (16 buildings), and the mixed-use typology currently makes up 14% (12 buildings). Including projects that are currently under construction or proposed, there were 139 total projects matching the audit’s criteria.

In terms of height, 12 of the 20 tallest structures are located in Europe. Scandinavia had 4 of those, while the UK and Australia had 3 and 5 apiece, respectively. Additionally, the height of the world’s tallest timber building, now officially the soon-to-be-completed 25-story Ascent tower in Milwaukee, has tripled in jus...

What's it like inside the world’s newest mass timber developments?

Above our heads, the pillars and struts of the pergola looked like the masts of a gigantic ship—their edges rounded, like huge pencils, to diminish the force of winds that can pummel the tower. Between the heft of the wooden building and the evanescence of the fog encircling it, the atmosphere was seductively calming—as long as my mind did not linger on the metaphor of the matchbox.

The New Yorker takes us on a whirlwind tour of some of the higher-profile mass timber developments that have debuted in recent years. Stops include the future site of Henning Larsen’s Fælledby development outside Copenhagen, the Oslotre As-designed seven-story Valle Wood, and Voll Arkitekter’s 18-story, 280-foot Mjøstårnet tower near Oslo, which is now officially the world’s tallest new timber building.

Mjøstårnet’s developer Arthur Buchardt was on hand to speak to its significance relative to the future of the industry as well as the role timber building could play in his country’s changing economy.

“Most of us already live in wooden buildings — only not so tall,” he explained to reporter Rebecca Mead. “Norway is an oil nation, but the oil will end. All the politicians talk about ‘green change’ — we must do something else that must be environmentally friendly, and we must use local resources. I thought I could build something like this, as an answer.”

'World’s Tallest Timber Building' now officially ratified after CTBUH height criteria update

2019-03-14T18:20:00-04:00

[CTBUH] has verified the completion of Mjøstårnet, a mixed-use building in Brumunddal, Norway that now holds the unique title of the “World’s Tallest Timber Building.” At 85.4 meters, it is also the third-tallest building in Norway and the country’s tallest with mixed functions. This news coincides with the amendment of the CTBUH Height Criteria – the official guidelines upon which tall buildings are measured – to include timber as a recognized structural material.

The 18-story wooden structure Mjøstårnet (Mjøsa Tower) near Oslo, Norway popularly earned the title "World’s Tallest Timber Building" back in September 2018 when it structurally topped out. But it wasn't until a recent update of the Council on Tall Buildings and Urban Habitat's height criteria guidelines, that what truly constituted a 'timber' structural system was clearly defined.

The revised criteria for timber structures now requires that "both the main vertical/lateral structural elements and the floor spanning system must be constructed from timber. An ‘all-timber’ structure may include the use of localized non-timber connections between timber elements. A building of timber construction with a floor system of concrete planks, or concrete slab on top of timber beams, is still considered a ‘timber’ structure, as the concrete elements are not acting as the primary structure."

The world's tallest timber tower structurally tops out in Norway

Construction workers yesterday installed the final beam at Mjøstårnet (Mjøsa Tower), a wooden skyscraper project in the Norwegian town of Brumunddal, just north of Oslo. Now structurally topped out, the 18-story structure stands 85.4 meters tall and is officially the world's tallest timber tower.

Once fully completed in March 2019, the tower designed by Trondheim-based Voll Arkitekter will house apartments, a hotel, and offices on 11,300 square meters (121,630 square feet).

The world's tallest wooden tower is being built in Norway

2017-08-31T12:24:00-04:00

With an expected completion date of March 2019, the 18-story, 80-meter-tall-plus building in Brumunddal, Norway known as the Mjøsa Tower will soon become the world's tallest wooden structure, a coveted title among those designers who favor wood over more traditional tall building materials. Designed by Voll Arkitekter, the Mjøsa Tower is on track to supersede the previous wooden record holder, the Brock Commons Student Housing building at the University of British Columbia, which topped out at a stately 53 meters in height.

Wood has numerous advantages over oft-used concrete and steel: for one, the construction time can be cut approximately in half due to easy prefabrication and the overall lighter weight of the materials. Surprisingly, one of wood's advantages as a tall building material lies in its ability to withstand fires, at least when compared with the tendency of steel to melt down during an all-consuming blaze. As the site's general contr...
