Setra has been commissioned to supply locally produced cross-laminated timber (CLT) and glue-laminated timber (glulam) for the Lumi district in Uppsala, Sweden.

According to a press release by Setra, Swedish real estate company Vasakronan is transforming a 1970s concrete building into a state-of-the-art and more sustainable office space.

Setra’s deliveries started in December 2022 and amount to a total of 1,200 cubic metres. The project involves six beams made of CLT for new floors in three blocks, a new atrium linking the buildings with footbridges made of CLT, and glulam for the roof structure of the atrium.

“This is the first time we have worked with Vasakronan, and it has been great. They have a clear environmental and sustainability profile and are at the forefront of the circular economy and reuse,” said Theres Jansson, sales representative for Setra’s building solutions.

Vasakronan is a real estate company based in Sweden, and owns, manages and develops centrally located office and retail properties in Stockholm, Gothenburg, Malmö and Uppsala.

The Lumi district is part of the Södra city urban development project that is taking shape between Resecentrum travel centre and the Fyrisån river. An existing office building is to be extended by three floors without making changes to the foundations. The solution is to dismantle a very heavy concrete facade and replace it with much lighter material.

“By using timber beams made of CLT instead of concrete, we save weight. And as we are dismantling the concrete facade at the same time, there is no need for underpinning,” explained Vasakronan’s project manager Jonas Wahlström.

“In our procurement dialogue, we make an assessment based on a wide range of parameters. These include sustainability, digital maturity, geographical proximity and security of supply. It is important that we have suppliers that provide security for us as customers, and that was one of the reasons why we chose Setra.”

“Another reason was that Setra’s employees were very helpful, clear and solution-oriented when we were reviewing their tender. Also, Setra met our technical requirements, including those for the weight of materials.”

Lumi will consist of three blocks connected by an atrium. There will be a total of seven floors with approximately 15,500 square metres of open and bright office space. The street level will be redesigned to accommodate small shops, restaurants and other services.
