The £5 million refurbishment and extension of the Science Block at Radley College, Oxfordshire, which serves the Physics and Chemistry departments, has been completed. Originally designed by architect W.G. Newton in 1937, the building was constructed with an exposed concrete frame and infill panels, with large areas of Crittall windows set between structural bays. Over the years, however, the building’s original form and character had been altered, diminishing its aesthetic appeal. The window pattern was dramatically changed, several extensions were added, and the original flat roofs were replaced with maintenance-free low-pitched industrial metal roofs, further distorting the building’s historic character.

The scope of the project focused on re-establishing a cohesive aesthetic for the building, one that responded to both the original structure and its later additions. Existing spaces were refreshed and reconfigured to better serve the educational needs of the college.

 

In addition, several new extensions were added to accommodate an increased number of laboratories for both Physics and Chemistry. The key addition was a purpose-built 190-seat Science Lecture Theatre (SLT), which significantly enhances the facility’s capacity for large classes and special lectures.

​

One of the main challenges of the original building was its complicated internal circulation, which created confusion and lack of identity for the Science Department. The internal horizontal and vertical circulation routes were convoluted, making it difficult to navigate between departments. The project sought to address these issues by rationalising the circulation, creating a more direct and legible route that revolves around a new top-lit central atrium space. This atrium acts as a unifying element, connecting the ground-floor Chemistry department with the upper-floor Physics department, and helping to give the building a clear and functional identity.

​

A striking feature of the refurbishment is the new Science Lecture Theatre, which has a dramatic circular form. Situated at the open end of the splayed wings of the existing building, the SLT is partially glazed and partially rendered. The circular shape of the theatre is accentuated by a series of aluminium vertical fins, which sit in front of fritted glazing, adding a contemporary touch to the building's design. This feature not only adds visual interest but also serves as a functional element, allowing for natural light to penetrate the space while controlling glare.

In contrast to the existing building, the construction and materiality of the new rooftop extensions are lightweight and modern, finished with zinc rainscreen cladding. These extensions provide additional space while offering a stark contrast to the solidity of the original structure. The existing building’s pitch roofs, which had been altered over the years, have been removed, and the building has been returned to its original flat roof form, further restoring its architectural integrity.

​

The refurbishment successfully blends modern design with historical preservation, providing Radley College with a functional and aesthetically pleasing Science Block that respects the past while meeting the needs of the future. The combination of new and old materials, as well as the improved circulation and additional spaces, has revitalised the building, creating a modernised environment for the teaching of Physics and Chemistry.
