Renton Hall Extension

The Renton Hall project was commissioned by a private domestic client and undertaken by WT Architecture, a renowned architectural firm. This project successfully blended the preservation of historical architecture with the introduction of modern design elements.

We divided the structural engineering efforts into two distinct phases.

Phase 1: Renovation of the Georgian Manor

The first phase focused on restoring the neglected manor house, which had been vacant for several years. This involved stripping the building back to its structural shell and addressing various structural deficiencies, including to optimising the attic space. We carefully considered the existing structural elements during the renovation, ensuring we maintained the integrity of the original building while meeting modern standards.

Phase 2: Modern Extension

The second phase involved adding a modern extension to the side of the original building. This extension was designed to complement the existing structure sympathetically, maintaining the historical aesthetic while incorporating contemporary architectural features. The structural design of the extension required innovative solutions to integrate new materials and construction techniques with the old building.

A variety of materials were used throughout the project, with a significant focus on exposed timber, which played a critical role in both the aesthetic and structural aspects of the design. We enhanced the standard blockwork with a high-quality masonry render, ensuring the extension blended seamlessly with the original structure. We also employed steel tie rods, particularly in the extension, to achieve an open and airy space. These tie rods provided essential structural support while allowing for a modern, uncluttered interior design. Other structural elements included steel ties and slappings, which were utilised to fit out the existing house effectively.

One of the primary challenges faced during the project was the ground conditions, which posed difficulties with drainage. However, the superstructure of both the original building and the new extension remained stable throughout the process. The Narro team successfully navigated these issues, ensuring the integrity and longevity of the project.

Throughout the Renton Hall extension project, there was close collaboration between the structural engineers and the architect. WT Architecture had a clear vision for the design, and the engineering team provided various structural options, particularly concerning the extension’s truss forms. The decision to use steel tie rods was a result of this collaborative process, enabling the final design to meet both aesthetic and structural goals.
