Low Harperley Farm, County Durham

In December 2018, a fire sparked by a log-burning stove severely damaged Low Harperley Farm, a 300-year-old Grade II* listed property in Durham. The fire destroyed half of the property’s roof, leading to a two-year restoration project, with Perega’s consultancy and structural engineering expertise at the forefront.

The majority of the structure dated back to the 17th century, featuring large oak trusses and purlins. The conservation authorities were keen to not replicate the original structure and so Perega opted instead to incorporate contemporary elements such as steel purlins and modern timber rafters to form the new roof structure, whilst ensuring the project adhered to the stringent regulations governing Grade II* listed properties. The historical aesthetics of visible areas were maintained by using horsehair lime plaster, in line with traditional construction methods. Additionally, traditional lime mortar was used to rebuild the stonework, preserving the property’s authentic charm and heritage.

Following the destruction of one floor by the fire, the left wing of the property underwent a complete transformation. Perega worked within the regulations to make it possible to convert it into a breathtaking two-storey open lounge with an elegant chimney, creating an artful and functional living area.

The Low Harperley Farm restoration is another example of our dedication to preserving heritage properties while incorporating modern engineering solutions, ensuring their longevity for generations to come.
