Warksburn Old Church is a locally-listed Victorian-era church based in Northumberland. It is being converted to a 3-bedroom holiday let and will be certified to the Passivhaus EnerPHit standard.  During 2023-24 it was converted from a redundant Presbyterian church, which was originally built in 1875.  


Ecospheric has supported the project as Passivhaus and building services designers. The team has specified a component method approach to achieving certification with a thermally efficient structure constructed within the existing stone building, coupled with the integration of renewable energy generation. The project has achieved an outstanding initial airtightness test result of 0.19 ACH.


The conversion of this refined and distinctive home was has been spearheaded by the property owners, Anne and Alan James. The rebuilding programme has not only repaired and retained historic features, such as the stained glass windows and soaring timber roof trusses, but also transformed the former church into one of the most energy efficient buildings in the UK, which generates more energy than it consumes.


Anne and Alan have uncovered the extraordinary history behind the church, which was originally funded by engineer Sir George Barclay Bruce who was the first to articulate the concept of renewable generation and storage of electricity in the 19th century. Now, Alan and Anne - who are renewable energy pioneers of the 21st century - are bringing Sir George's vision to life with their Net Zero historic church. Read more about this story here


Alan presented the journey of this unique retrofit at Grand Designs Live with Kevin McCloud in May 2024.
