The Marble Pier: a timber wonder

Timber is one of the oldest building materials, but it has recently come back in style as a sustainable alternative to concrete and steel. In Copenhagen’s Nordhavn neighbourhood, a towering new project perfectly encapsulates why.

With eight storeys, the 36-meter-tall building covers 28,000 square metres. This makes the Marble Pier one of the largest timber buildings ever constructed in Denmark and home to some of the most sustainable offices possible with existing technology

. By using timber, the carbon footprint of the Marble Pier is reduced by approximately 50% compared to a traditional concrete build, resulting in 9,500 tonnes fewer total emissions. Of that, 3,000 tonnes are avoided emissions by using timber instead of concrete, and 6,500 tonnes are sequestered by the timber during the building’s lifetime.

Ramboll and Henning Larsen Architects, alongside the contractor Hoffmann, are the sole project designers for the Marble Pier, responsible for the multidisciplinary project from concept to construction, including a full life cycle assessment on behalf of the client, AP Pension, one of Denmark’s largest pension funds.

“In AP Pension, we are doing everything we can to push the buildings industry in a more sustainable direction. That is why we are primarily using timber for the load-bearing structures at the Marble Pier,” said Peter Olsson, CEO of AP Pension’s real estate subsidiary, AP Ejendomme, to Estate Media in March 2022.

“This is the first time we work with timber in a project of this size, but we want to lead the green transition, and that requires using materials that can reduce the carbon footprint,” he adds.

Better office, better health

Building in timber also has benefits for wellbeing and health. For one, building inhabitants are exposed to fewer toxins than in a similar build using traditional materials. And timber constructions are better able to regulate moisture levels, resulting in an improved indoor environment.

At the Marble Pier, several rooftop gardens provide guests and residents a chance to enjoy a break in a green, natural environment. The gardens simultaneously double as oases for biodiversity, with beehives and butterfly ‘hotels’ placed alongside the vegetable gardens supplying fresh produce for the building’s restaurant and café.

Integrating nature into building projects not only improves their look and feel but has tangible benefits for the companies residing there.

According to one study from the University of Oregon, 10% of employee absences could be attributed to poorly designed buildings that did not allow workers to connect with nature. Simply having a view of trees reduced sick leave hours from 68 hours per year to 57 hours per year on average, the authors found. As 90% of operating costs in office buildings are staff related, integrating nature directly into office settings can help reduce stress and sick leave with clear benefits for companies’ bottom line.

The Marble Pier is expected to receive the highest possible sustainability accreditations for buildings, namely, DGNB Platinum, as well as the WELL certification.

Located on a pier side development in Copenhagen, Denmark, construction of the Marble Pier began in 2021 and is expected to be completed by 2024.
