Designing the Future

Honoring the Past

Enriching Lives

Originating in 2019

Studio Kathryn Larsen began with a simple idea - to look closer at the materials we use for architecture, and design from the smallest details up.

Studio Kathryn Larsen transforms existing buildings and gives them new life, together with communities and stakeholders.

With nearly ten years of professional experience and Danish construction industry expertise, Studio Kathryn Larsen designs renovations that save clients time, money and energy - while preserving the charm and soul of older buildings.

In 2025, we are developing our first project: transforming the Eskilstrup Community House into a Culture House.

We also design artistic installations and objects from ocean-derived materials.
