Our Story

Ecospheric is an award winning Passive House consultancy that supports planners, architects and developers in designing and delivering pioneering eco developments that save carbon and drive technological change. We have supported projects ranging from complex Passive House retrofits, innovative Paragraph 80 houses on landed estates, to the design of multi-story Passive House residential developments and low energy commercial buildings.

Our ambitious developments lead the industry in incorporating the latest low energy technologies and methodologies. Ecospheric's current property developments include a food hall aiming for zero energy and zero waste,  5 new build zero petrochemical and concrete free certified passive houses, the zero energy renovation of an Elizabethan grade II* listed manor house and the conversion of a 300 year old Yorkshire barn to off-grid group accommodation. 

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.
