Project Overview

The Brierley Building, a Grade II* listed landmark within the Northallerton Conservation Area, was purpose-built in the early 20th century and continues to serve as the headquarters of North Yorkshire County Council.

Scope of Works

Delivered in two distinct phases the project focused on sensitive repairs to historic plasterwork and roof coverings, alongside upgraded electrical services and internal refurbishment, ensuring this important civic building remains fit for modern use while preserving its architectural significance.

Repairs to the external envelope of the building were carried out to prevent water ingress re-occurring, this involved replacement of failed lead work, repair of the downpipes and patch repointing of the external masonry with a lime mortar mixed to match the original. These repairs were carried out to a high standard using like-for-like materials and methods that had previously stood the test of time. Repairs to the fibrous plaster ceiling panels included consolidation and re-wadding works to strengthen the ceiling structure, and to improve the aesthetic look of the ceiling from below by filling holes and cracks to the plaster.

Challenges & Our Approach

Uncovering and Responding to Historic Conditions

As is typical with heritage buildings, further elements of the structure were revealed as ceilings and voids were carefully opened up. These discoveries provided valuable insight into the building’s fabric and informed sensitive repair solutions. The project team worked collaboratively and flexibly to address newly identified issues, delivering high-quality repairs that respected the building’s heritage while fully meeting the Client’s requirements.

Access and Scaffolding

Given the building’s sensitive fabric, no load could be placed on the roof and no scaffold ties were permitted. To overcome this, a rare, fully free-standing scaffold structure was constructed, wrapping around the entire building without making contact and maintaining full vehicle access. The structure supported a temporary roof to fully protect the building and a suspended, tiered scaffold system, providing safe access for specialist restoration works. This highly complex solution demonstrates the technical expertise required to deliver conservation projects of this scale.

Outcome

The completed works were praised by Historic England, with a representative highlighting the high quality of workmanship and describing the project as a strong example of how historic buildings can be sensitively refurbished to support continued use. The project was further recognised at the LABC Awards, receiving a Highly Commended accolade for Best Refurbishment of a Listed Building.
