We were founded to challenge the status quo and have worked radically with sustainability long before it became common practice.

With 35 employees based in Denmark and Iceland, we work to accelerate the green transition in the built environment through architecture, urban planning, strategic consultancy, and material innovation.

Responsibility, honesty and transparency are at the core of everything we do and it’s what keeps us critical – of ourselves, of the industry, and of the systems we work within. The journey towards circular construction has only just begun.

We’re not afraid to experiment and explore alternatives, but never without proper due diligence and risk management.

Through years of navigating the laws, frameworks, and limitations of the built environment, we’ve built the expertise and methods to push boundaries. Our many realized projects stand as proof of an abundance of possibilities – and huge aesthetic potentials for a new architecture.

Founded by Anders Lendager in 2011, our company set out to challenge norms and pioneer more sustainable solutions in architecture. By rethinking waste – like turning old windows into upcycled glazing and brick walls into new facades – we developed innovative, circular materials.

From our roots as a small startup, Lendager has grown into a well-established, world-leading consultancy specialized in sustainability within the built environment. During this journey, market requirements and laws incentivizing and mandating greater circularity and sustainability have developed rapidly, and our projects have become international reference points for this paradigm shift.

We are a diverse group of employees with a wide range of professional skills, educational backgrounds and national backgrounds. This enables us to approach projects from a broader perspective and develop qualified solutions.

In Copenhagen, we work in a former train workshop, in Aarhus we’re located in ‘our’ timber high-rise TRÆ – and in Iceland, you’ll find us in the heart of Reykjavik. In all of our offices we’re surrounded by green plants, full-scale mock-ups, and material experiments.

We integrate circularity and sustainability into every aspect of our organization – from the way we sort our waste to our commitment to ensuring that our employees have the best possible work environment.

We specialise in transforming existing buildings and reusing materials.

Guided by the design principle that “form follows availability”, we start with what’s already there – uncovering new aesthetics, ranging from expressions that appear entirely new to those that reveal historical layers and showcase the prior life of the materials.

Reuse is more than a practical choice; it connects past and future, creating buildings rich in narrative. We know this from the users of the buildings we have realized until now, who greatly appreciate the feeling of living with materials that carry a story.

For us, it’s about preserving what holds value and giving it a meaningful, new life for the benefit of people and planet.
