Steensen Varming

Steensen Varming is a building services consultancy founded in Copenhagen in 1933 by Niels Steensen and Jørgen Varming. Its reputation was built on competition-winning collaborations with architects, above all the Sydney Opera House, where the practice designed the air-conditioning and has maintained and refined the building’s systems ever since.

The firm works across mechanical, electrical, fire, lighting and sustainability engineering, with studios in Copenhagen, London, Sydney, Canberra, Hong Kong and New York. Projects range from museums, universities and healthcare buildings to heritage refurbishments, approached through a Danish idea of refinement and longevity rather than technical display.
