Rosslyn Castle, dating back to the 13th century, had been in use as a rental property under the management of the Landmark Trust. However, its age and design left modern-day visitors uncomfortable in the bitter cold. This problem was particularly acute in the ground-floor rooms, where the plasterwork, originating from 1620, remained beautifully preserved but poorly insulated. Occupants often found the building too cold, resulting in frequent early departures. Additionally, the old courtyard had become a collapsed ruin, and much of the castle had fallen into disrepair.
A significant part of the renovation was the reconstruction of the courtyard, which had been empty for centuries, to create a Grand Hall. The newly built grand hall features timber beams that span an impressive 10 metres in length. These beams, sourced from France, add a stunning architectural feature to the hall and pay homage to traditional craftsmanship. The completed renovation now offers modern comfort, with the castle accommodating up to eight guests in a warm and inviting space, while still maintaining the building’s original character.
The engineering complexities extended beyond insulation and heating. Scaffolding for the five-storey building presented its own set of hurdles. Due to the listed status of the castle, the scaffolding could not be fixed to the building itself. Instead, it had to be designed to withstand wind loads independently, secured by kentledge (counterweights) to prevent movement. This bespoke solution ensured that no part of the historic structure was compromised during the restoration process.
Drainage was another critical issue to solve. The existing drainage system was outdated, and modifications were restricted by Historic Environment Scotland. This was particularly in relation to the low garden walls, believed to date back to the 16th or 17th centuries. The project team devised an innovative solution involving the installation of two pumps to transport water over the historic walls, as excavation below ground was not permitted. This thoughtful approach preserved the integrity of the garden walls while providing a modern, functional drainage system.
The ambitious project to reinstate, restore and renovate Rosslyn Castle, a category A listed building, posed a multitude of engineering challenges that demanded precision, innovation, and sensitivity to the site’s historical legacy. Page\Park Architects, working on behalf of the Rosslyn Castle Trust, led a remarkable effort that combined heritage conservation with considered conservation engineering to breathe new life into this historic Scottish landmark.
To address these concerns, Page\Park implemented an extensive overhaul of the castle’s insulation and heating systems. Underfloor heating was installed throughout the structure. Additionally, air-handling units with heat exchangers were placed in the vaults to provide a more efficient and sustainable means of temperature control. These modern interventions were carried out with extraordinary care to preserve the building’s heritage. For example, panelling was carefully removed and replaced in exactly the same manner after the insulation work was completed, ensuring the historic fabric remained intact.
One of the more complex challenges in the project involved the local ecology. During construction, bats were discovered in the building, particularly in the lower vaults. This situation required strict compliance with conservation legislation. It meant certain areas were rendered inaccessible during the works, and special provisions had to be made to accommodate the bats. A bat box was integrated into the roof as part of the upgrades, further demonstrating the project team’s commitment to environmental stewardship alongside the restoration effort.
The restoration of Rosslyn Castle showcases the careful balance between preserving historic architecture and implementing modern engineering solutions. The difficulties posed by the castle’s remote location, ecological concerns, and conservation restrictions were met with ingenuity and expertise. Today, Rosslyn Castle is a fine example of both Scotland’s rich heritage and the possibilities of modern restoration techniques. It offers a unique and comfortable experience for visitors while safeguarding its ancient history for future generations.
