Replacement Windows For A Grade II Listed Commercial Building in Yorkshire

Grade II Listed Building Windows Replaced For Commercial Offices at Aberford Priory, Leeds

When it comes to replacement windows for commercial listed buildings in Yorkshire, the challenges are unique. Historic properties like Aberford Priory, a Grade II listed building in Leeds, demand a solution that respects their heritage while providing modern performance. This project, undertaken for Michelin Connected Fleet at Aberford Priory, was no exception, requiring a delicate balance between preserving historical integrity and addressing critical issues of rotting timber and leaking windows. This case study details how we successfully navigated these complexities to deliver a durable, energy-efficient, and visually authentic commercial window replacement in Leeds. Our solution, utilising Accoya timber and specialised thermally efficient glazing, not only met the stringent requirements for a listed building but also significantly improved the comfort and sustainability of the newly refurbished offices.

  • Project: Replacement of all windows in a Grade II listed former church, now converted into commercial office space.
  • Challenge: The original timber windows were severely rotted and leaking, compromising the building’s integrity and energy efficiency. As a Grade II listed building, the replacement had to meet strict conservation requirements while providing modern performance. Additionally, disruption to a live business premise had to be kept to a minimum.
  • Solution: Expertly crafted new windows using Accoya timber and special thermally efficient glazing, approved for use in a listed building. Off-site fabrication of the prefinished, bespoke windows in our nearby Yorkshire workshop ensured expedient installation and no disruption to the site.

Grade II Listed Building Challenge: Replacement Windows That Preserve Character

The preservation of historic character is paramount when working on a listed building. The Aberford Priory project required a solution that would replicate the appearance of the original windows while addressing their failures. The old windows were not only deteriorating but also failing to provide adequate thermal insulation, leading to heat loss and discomfort for the occupants. A key part of the project was to find a material that could withstand the elements without compromising the aesthetic.

Listed Window Frame Soution: Accoya Timber A Perfect Match That Will Last Beeyond Half A Century

Our team designed and manufactured replacement windows that perfectly matched the original frames’ style and proportions. We chose Accoya timber for this project due to its exceptional durability and stability. Accoya is a modified wood that is highly resistant to rot, decay, and warping, making it an ideal choice for the long-term protection of a listed building, replacing the leaking, rotten former frames. Accoya’s longevity and low maintenance requirements were a key factor in gaining approval from conservation officers.

Replacement Grade II Listed Window Solution: High-Performance Glazing

To enhance energy efficiency, we installed a special thermally efficient glazing system across all wall windows and the characteristic rooflights. This glazing, specifically approved for listed buildings, significantly improves insulation without altering the visual appearance of the windows. The new units have drastically reduced heat loss, leading to a more comfortable working environment and lower energy bills for the commercial occupants.
