Work on the new North Block building will start by August with completion scheduled for 2018.

The works will extend the school’s teaching, rehearsal and performance spaces, and will include the addition of studios with a focus on training for film/ media and a new public, courtyard theatre.

Graham will construct a contiguous piled wall around the site perimeter and reinforced concrete lined walls will be built below ground level to form a double-storey basement, followed by the construction of an in-situ reinforced concrete frame for the six floors above ground.

The new facility will be traditionally-clad and painted stucco to integrate with the surrounding architecture of the Belsize Conservation Area.

Sustainable design solutions including photovoltaic panels and natural ventilation methods will be installed to reduce the environmental impact of the running of the building.

Graham Construction’s London Office Director, Rob Joyce said: “The Royal Central School of Speech and Drama’s vision to provide high quality, bespoke teaching and performance spaces that meet its students’ needs and uphold its world-leading reputation, will be further realised with this development.

“Distinctive, fit-for-purpose theatrical and performing arts facilities will integrate with local architecture and contribute to the surrounding cultural quarter, creating a long-term sustainable solution.”
