Raby Castle and Estate, in the heart of County Durham, is committed to sustainability as part of its highly ambitious two-year redevelopment and restoration plan, known locally as The Rising.

The Estate has drilled two exploratory geothermal boreholes to identify whether a renewable energy source will help meet the annual heating requirements of The Rising scheme.

The Rising is the largest project undertaken at the Estate for generations and involves the restoration and repurposing of three beautiful heritage buildings in the magnificent grounds of Raby Castle, providing a unique experience for visitors. As well as the construction of two thoughtfully designed new buildings, it also includes the remodelling of the historic Walled Garden and the creation of landscaped public areas.

The project will open-up spaces that have never been seen by the public before, as well as introducing new event and exhibition spaces, retail, dining and a new visitors information centre. The first phase, the building of The Plotters’ Forest Adventure Playground and new visitor’s car park was completed in 2022, with the second phase currently ongoing.

Sustainability and futureproofing are a key focus for the Estate, and its custodian, Lord Barnard. Whilst expansion often means further demands on resources, there is a commitment to lessen the environmental impact of the development.

Raby Estate has been working closely with local specialist designers TGA Consulting Engineers, to explore renewable energy. The designer’s in-house Mechanical, Electrical and Building Performance teams have demonstrated, through in-depth analysis, that heat can be extracted from the ground via an ‘open loop’ Ground Source Heat Pump system, to provide 60% of the annual heat demand of The Rising scheme and reduce the development’s carbon emissions by 40%.
