Repairing, enhancing, and future proofing a Modernist building

Introduction

The Grade II-listed Hilda Besse Building is a distinguished example of post-war Modernist architecture. Designed by John Partridge of Howell, Killick, Partridge and Amis, the building marries the signature style of Modernist buildings with the centuries-old Oxford tradition of long common rooms and dining halls. It received both the RIBA Architecture Award and the Concrete Society Award in 1971.

Our restoration approach was shaped by a detailed review of original construction drawings and historical photography, revealing deviations from the initial design intent. This research informed a carefully considered strategy that sought to honour the building’s original architectural vision while adapting it for contemporary use. 

With over five decades of continuous use, Hilda Besse had begun to show signs of wear. Using our expertise in 20th-century buildings, we developed a conservation strategy that preserved the structure’s defining features while addressing damage and deterioration. 

Key enhancements included the repair of exposed concrete and restoration of original architectural details; rationalisation of internal layouts to improve spatial efficiency; and upgrading of services and systems in line with modern standards, without compromising heritage value.

Improving the building’s environmental performance was integral to the project. Originally constructed in the 1970s, Hilda Besse suffered from poor thermal efficiency. Our work introduced discreet insulation upgrades and modern glazing, improving internal comfort and reducing energy demands. 

These changes contribute to the building’s long-term sustainability and support the well-being of its users, aligning with the college’s broader environmental goals. 

One of the significant challenges was maintaining college operations during construction. To mitigate disruption, we provided temporary facilities for the dining hall, kitchens, and common room, allowing academic and social life to continue uninterrupted. 

 The project’s success was underpinned by five years of collaborative planning, consultation, and coordination with college stakeholders, including faculty, students, and alumni. This inclusive process ensured the final design reflected both the functional needs and cultural identity of the college.  

 

Accessibility

A major focus of the project was to ensure full accessibility across the building and surrounding site. Previously stepped main entrance lobbies were reconfigured with integrated ramps and powered doors, eliminating barriers to entry. A new, enlarged lift and a secondary circulation route were introduced to provide step-free access to all levels. 

We also redesigned parts of the ground floor to accommodate improved toilet facilities, including fully accessible provision, ensuring compliance with current regulations and universal design principles. 

Externally, accessibility was improved by extending the building’s plinth into the central quad. This intervention created a continuous level surface linking Woodstock Road (West) and Winchester Road (East), significantly enhancing movement across the site.
