The Round Reading Room

TGA designed new close control air conditioning systems to enable the famous Round Reading Room to be used as a flexible, special exhibitions gallery, initially for China’s Terracotta Army



TGA developed an innovative heating and cooling system which is embedded into wall finishes at high level and significantly improves visitor comfort in these popular galleries.


The refurbishment of Galleries 90..94 included replacement of the air conditioning plant and new case lighting systems in order to maintain environmental conditions for sensitive artefacts.

Clocks & Watches Gallery

Exhibiting Clocks in an historic building environment presents significant challenges in maintaining suitable environmental conditions. TGA developed an innovative solution which was shared with the adjacent Medieval Gallery.

The Manuscripts Saloon

The Manuscripts Saloon sits on an important crossroads within the British Museum’s circulation routes and incorporates carefully concealed and co-ordinated electrical containment systems.


The PDF Gallery

The PDF was formed as a new gallery space within a former back of house area. It is connected into wider M&E infrastructure designed by TGA for this purpose as part of adjacent projects.

The Nebamun Gallery

This unusual gallery mimics alludes to the interior of an Egyptian cave and presents ancient wall paintings in an environment with tightly controlled lighting levels.

The Medieval Gallery

TGA undertook extensive thermal modelling to enable the very busy gallery to benefit from free night cooling to minimise the need to provide mechanical cooling.
