Ibstock Place School

This cathedral-like dining hall for Ibstock Place School in south-west London has sustainable environmental design features that are just as impressive as its sheer size.

Challenge

Replacing the existing dining hall with new high-quality dining facilities and a new multi-purpose space for sixth-form students, the new refectory features a striking glulam lattice-frame ceiling with inset panels of oak. The dining hall, seating over 500, provides a multi-use space throughout the day and serves as an inspiring high-quality venue to host evening events such as parents’ evenings and productions. The mezzanine-level multipurpose space offers social and study space, and provides access to the sixth form area.

Our sustainable environmental design maximises the use of natural light and ventilation with extensive consultation and modelling completed to ensure the building is designed to reflect how it will be used. Advanced works were completed to divert services and demolish the existing building prior to constructing the new refectory. We also upgraded the electrical supply to the wider campus to support the new refectory and rationalise a number of existing supplies. 

To keep with the building’s simple elegance and clear lines, the advanced services had to be implemented as discreetly as possible, which required some creative engineering solutions. Even though the building accommodates a full commercial kitchen with specialist pastry room and hospitality annexe, the large kitchen ventilation ductwork is not visible. This is because it is hidden in a specially designed chimney that blends unobtrusively into the overall picture.

Light-filled and naturally ventilated

The scheme is split into three glazed lanterns, their roof volumes supporting a natural ventilation strategy. Taking a mixed-mode approach, the building is predominantly naturally ventilated but can use mechanical ventilation with high-efficiency heat recovery in winter months. 

The light fittings in the main spaces were specifically adapted for the project. In collaboration with Jonathan Coles and Maccreanor Lavington, we undertook a light modelling study to develop the specification requirements for the lights in the refectory. This led to the decision to have direct and diffuse dual light sources - each capable of independent control for scene setting.

Outstanding acoustic environment

The client had high aspirations for the acoustics of each of the spaces. The refectory received a lot of acoustic treatment, which required detailed coordination of services with the distinctive timber structure. In particular, the main hall needed to be able to seat hundreds of pupils without excessive noise levels while also supporting assemblies and musical performances. Concealing both the acoustic treatment and the drivers for the lights, oak panelling was set between the glulam and used on the walls to help absorb and diffuse sound in the dining areas to provide a more comfortable and natural-sounding environment.

“The magnificent three-volume brick and timber refectory for Ibstock Place School in south-west London takes the school meal experience to a whole new level.”
