Home > Education > Dulwich College Extension Project

In April 2023, GA Interiors Ltd embarked on a £14 million extension and refurbishment project for Dulwich College, marking a significant phase of the school’s masterplan developed by John McAslan + Partners. The project involved replacing a 1950s structure next to the iconic, listed Charles Barry Junior-designed private school, which has stood in south London for nearly 400 years.

Our team was tasked with delivering high-quality drylining, steel framing systems (SFS), and fire stopping for the S-shaped building. The design features a striking three-storey atrium, state-of-the-art science laboratories, and a 240-seat auditorium. Five ‘Informatics’ suites and dedicated floors for biology, physics, and chemistry provide flexible learning environments, with the ability to adjust individual lab spaces into versatile ‘science studio’ setups.

Over 14 months, GA Interiors Ltd ensured every aspect of construction met the highest standards, creating a safe, modern, and adaptable educational space. Completed in June 2024, the project not only enhances the physical infrastructure of Dulwich College but also enriches the learning experience for students, blending tradition with forward-thinking design.

We are proud to have played a role in shaping the future of this historic institution.
