Our Story

Ecospheric focus on pioneering eco developments that save carbon and drive technological change. Our mission is to create valuable case studies to progress the field of sustainable construction. 


Our business has grown from offering energy-efficient retrofit advice to homeowners to developing groundbreaking Passivhaus properties and providing consultancy services to architects, councils, social housing providers, and one of the UK's largest food retailers.

As a trusted name in sustainable building, Ecospheric's offerings expanded in 2012 to include the specification and sales of energy efficient glazing. Ecospheric Windows and Doors is the preferred supplier to some of the Northwest's most reputable homebuilders with a range of high performance and Passivhaus products.

We're also passionate about sharing our knowledge so that everyone in the building sector has the skills to reduce carbon in the built environment. Ecospheric offers a range of CPD courses, tours, lectures, and events.
