Adaptive reuse & renovation

Preserving resources, memories and identity

Reuse, renovation and restoration of existing buildings are the most sustainable way to build. When we rethink and release the potential of the building stock we already have, we reduce CO2 emissions and the environmental footprint, extending a building’s lifespan significantly.

Making the most of the buildings we already have also allows us to physically capture and feel time; when we recycle and transform, we allow the generations to come to take part in and share our shared history and cultural heritage – and add new meanings and layers to them.

The most sustainable buildings, are those already standing. 

 

Architecture with respect

To move forward, we must increasingly look to the past. What we need is often already there, waiting to be revealed and reimagined. With this in mind, we approach adaptive reuse and renovation projects with respect and restraint, taking the time to understand existing structures, materials, details and stories before adding anything.

The renovation of Realdania’s headquarters in central Copenhagen demonstrates how restraint became the guiding principle throughout the process. From the outset, our ambition was to restore and reuse as much as possible – and discard as little as possible. By allowing the building’s original materials, craftsmanship and character to lead the transformation, we reimagined the workplace for present and future generations while preserving its modernist DNA.

Realdania’s 4,400 m² headquarters, a modernist masterpiece from 1959, has been brought back to its original character through a careful renovation in collaboration with LAIKA Rumdesign. Original mosaic tiles were uncovered beneath linoleum, wooden floors were restored, and teak doors, brass handles, and lamps – stored for decades in the basement – have been reintroduced and given new life across the five floors.

When reusing existing structures, materials and spaces, we preserve not only resources, but also place, memory and identity.

 

Building on what is already there

In a time of increasing environmental and social pressure, we need to continually ask whether new construction is the only answer. We must always be critical towards the default options and be curious about what other solutions exist.

This was the case at Novonesis Innovation Campus when revitalising and extending the campus became the solution to having outgrown their home. Rather than relocating entirely, with close to 50,000 m² of new construction, which was the initial plan, we added a 15,000 m² extension to link the existing campus together. This not only reduced environmental impact and costs but also respected employees’ ties to the site and its setting.

At Novonesis Innovation Campus, extensions weaved in between the existing buildings has connected the campus. Before the transformation, employees were spread across separate buildings, hampering interdisciplinary cooperation. Even though the buildings were dated, they were robust and surround by beautiful, mature parkland.

“If we genuinely wish to take better care of, preserve, and not least continue to use our architectural heritage, the authorities must add nuances into their requirements rather than rely on building regulations that call for universal solutions.”

Revealing inherent potential

Transforming an existing building begins with uncovering its potential – even when it is not immediately visible. We approach adaptive reuse and renovation projects by looking beyond surface conditions to uncover the inherent qualities.

When we first encountered KB32, many saw a rough and run-down structure, particularly from the outside. But inside, the building revealed spatial qualities, material strength and character that would be impossible to replicate today. Buildings of this nature are no longer made. For us, KB32 represented a rare opportunity: a generous framework and a blank canvas, rich with possibilities. The project stands as a reminder that even the most unloved structures can be reborn.

 

Built in 1967, the infamous 180-meter-long building was once part of Copenhagen's railway district, serving as terminal and storage for freight wagons. Today, it is a modern office and multi-functional workspace for up to 1,000 employees.
