The British Museum, Bloomsbury
MJ Long was co-designer with Colin St John Wilson for a new extension to the grade-I listed British Museum. The project includes a 430m2 temporary exhibition gallery, a workshop, a Trustees boardroom, public and staff restaurants seating 150 and 200 respectively, and 1,000m2 of flexible naturally ventilated office space.

The external appearance of the building is conditioned by the requirement for a substantial security wall and the need to reconcile the new construction with the main portico corridor and Smirke\'s residential pavilion.
