Donmar Warehouse - Dryden Street

Conversion into a Versatile Creative Hub

 

RIBA Award winning conversion of a 19th-century warehouse in the Covent Garden Conservation Area into rehearsal, education, and support spaces, including a rooftop dwelling for visiting artists. The design improved energy performance by 23% and is future-proofed for district heating.

 

The Donmar Warehouse, a leading theatre in Covent Garden, London, acquired a robust Victorian warehouse nearby Dryden Street. The building was converted into rehearsal, education, and support facilities, blending its original character with modern upgrades, including a rooftop extension for visiting artists, a new stair core, and a double-height rehearsal space.The Donmar Warehouse, a leading theatre in Covent Garden, London, acquired a robust Victorian warehouse nearby Dryden Street.

The project aimed to reduce energy use by at least 20% while creating a professional work environment within a limited budget and compact site. Dynamic thermal simulation modeling predicted a 23% improvement in energy efficiency and a 19% reduction in CO2 emissions, with provisions for future connection to a district heating network. Skelly & Couch provided full M&E design, monitoring, and support during construction. Following its success, they were appointed for the full refurbishment of M&E services at the Theatre.

Due to impracticality of insulating the existing external facade, roof insulation was enhanced for better thermal performance. Daylight modelling ensured natural light in rehearsal spaces and offices. Enhanced natural ventilation was incorporated throughout offices, green rooms, meeting rooms, the library, reception areas, and residential flats. High-occupancy areas, like the main rehearsal space, are mechanically ventilated with air supplied from a rooftop plant room.

A highly efficient heating plant, advanced lighting systems, and sophisticated BEMS reduce energy consumption. Additionally, sub-metering and targeted controls provide detailed insights into energy consumption patterns, enabling informed adjustments and savings, and a solar thermal array supplies energy to partially meet the building's domestic hot water needs, reducing dependence on non-renewable power sources.

Domar Warehouse creates an energy-efficient, creative and professional environment within a constrained urban space. It preserves the historical essence of the building while minimising its environmental impact.
