The British Museum

General Work

TGA Consulting Engineers LLP have worked at the British Museum for over 25 years, largely through a series of framework commissions.


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.

Gallery 30

TGA were appointed for the refurbishment of the M&E engineering services for the refurbishment of Room 33, which displays artefacts from the China and Asia.

Islamic Galleries

TGA were commissioned as M&E Consultants for the £12m redevelopment of Galleries 42..45 to form the new Albukhary Galleries, designed to “display objects from their diverse and world-class collection of Islamic objects”.
