The Roundhouse Trust



Built in 1846 as a steam engine repair shed, the transformation of the Grade II* listed structure required a fusion of architectural skill, historical respect, and the determination of funders.

Tolent led a multi-disciplinary team which saw the repair of the existing main fabric, reprogramming of sections of the building, to modernise the auditorium, increased its audience capacity to 3,600, and extended its functional range with a 3 storey extension to create an arts centre.

Care was taken to create a harmonious relationship between the old and new and, as part of the restoration, the circular glazed roof-lights were reinstated, allowing the public to see interior daylight for the first time in over 100 years.

The undercroft beneath the main space was redeveloped to house a state-of-the-art creative centre for 11-25 year olds to develop skills in performing arts, music and media. Live music studios, digital media suites, dance rehearsal rooms, a film production studio and a radio station have been created in the chambers and tunnels that are left behind.

The new build wing, constructed alongside the main building, houses the box office, bar & kitchen and offices. The existing conical roof was removed, the slates retained, and then reused, whilst a new acoustic roof was constructed with a structural steel support and services gantries above the main performance space.

Tolent led a multi-disciplinary team which repaired, modernised and extended the historic Roundhouse Theatre in London.


The project required extensive collaboration with English Heritage to ensure that the structural alterations did not compromise the historical integrity of the Grade II Listed building.
