Lendager is a Nordic, multidisciplinary consultancy firm with a declared mission to drive the industry towards a more sustainable and circular future.

Our built projects serve as prominent benchmarks for a new, resource-conscious approach to architecture, with several of them earning recognition for their innovative and aesthetically compelling solutions, both nationally and internationally.

Together with our clients, we harness our curiosity and years of professional experience – particularly with natural and circular materials – to constantly challenge current building practices and explore new, more sustainable paths. We thoroughly address today’s most pressing societal and corporate challenges, actively working to ensure our consultancy enables our clients and partners to thrive within planetary boundaries, whether it concerns CO2-emissions, biodiversity, or social justice.

Each project is an opportunity to transform business models, mindsets, and processes. As such, we work strategically at the portfolio level and concretely with individual materials and users.

We develop circular architectural projects, from early feasibility studies and concept development to design and completion. This is guided by our three core areas: Architecture, Advising and Innovation.

We are a diverse group of employees with a wide range of professional expertise and educational backgrounds. This enables us to approach projects from a broader perspective than just the architectural, providing our clients with well-rounded consultancy.

With more than 30 employees across offices in Copenhagen, Aarhus, and Reykjavik, we tackle tangible challenges related to sustainable transitions and circular economy in the construction sector.

Our Copenhagen office is housed in a former train workshop, surrounded by more than 150 green plants, 1:1 mock-ups, and material experiments. Sustainability is integrated into all aspects of our organization, from our waste sorting practices to our commitment to hosting social and professional events. Since 2019, we’ve exclusively served vegetarian and organic lunches to minimize our CO₂ footprint and promote employee health.

In Aarhus, we are based in our high-rise construction project TRÆ, and in Iceland, you’ll find us in green surroundings in central Reykjavik.

We specialize in transforming existing buildings and reusing construction materials.

Guided by the design principle “form follows availability,” we begin with the materials and buildings already at hand. We do not view construction materials as waste—instead, they carry stories, soul, and patina. This approach offers new design opportunities, ranging from a fresh, contemporary appearance to one that embraces visible historical traces.

Reuse and recycling are more than practical solutions. By reusing materials, we connect the past with the future, creating buildings that are not only more sustainable but also tell compelling stories. We know this from the people who have moved into the residential projects we have designed.

For us, it’s about preserving what has value and giving it new life in a way that is both aesthetic and functional, while respecting our planet.
