The iconic, Grade II* Listed Chichester Festival Theatre was designed by Powell and Moya and opened in 1962. Based on Tyronne Guthrie’s Festival Theatre in Stratford, Ontario, it boasted the first modern ‘thrust’ stage auditorium in the country. Over the past fifty years it has been a hugely successful and influential centre for the performing arts and has been extended on a number of occasions to address changing demands, leading to a dilution of the original design.

New Build and Refurbishment in a Heritage Context

4.5-hectare heritage public realm and new Discovery Centre for the Grade I-listed Chatham Dockyard. The project achieved major environmental improvements by eliminating heating in large areas and upgrading thermal insulation and building services systems. 2017 RIBA Stirling Prize finalist.

This multi-award-winning project at The Historic Dockyard Chatham preserved key Scheduled Ancient Monuments and the 18th-century HMS Namur timbers. It introduced world-class galleries, interpretation spaces, visitor facilities, a 4.5-hectare heritage public realm, and a Discovery Centre to highlight the dockyard's significance during the age of sail.

This multi-award-winning project at The Historic Dockyard Chatham preserved key Scheduled Ancient Monuments and the 18th-century HMS Namur timbers. It introduced world-class galleries, interpretation spaces, visitor facilities, a 4.5-hectare heritage public realm, and a Discovery Centre to highlight the dockyard's significance during the age of sail.Skelly & Couch provided full mechanical, electrical, public health, and environmental design for the project. Significant energy savings—both carbon and financial—were achieved, crucial to the long-term sustainability of Chatham Historic Dockyard Trust’s strategy. These were realised through enhanced thermal insulation and upgraded building services.

From the outset, the design prioritised environmental conditions to preserve the ship's timbers. The specialist advised maintaining them in their existing condition (as floor joists beneath the floor) without heating or ventilation. To address the thermal and latent loads from visitors, Skelly & Couch developed a natural ventilation strategy.

Undercutting the old timber north and south doors by 50mm allowed cross-ventilation and ensured adequate fresh air. Provisions were made for a future fan installation in the store beneath the link bridge adjacent to the undercroft, to accommodate potential temperature and moisture fluctuations. While the bays above and adjacent to the Namur undercroft are heated, many bays in the mast house and mould loft remain unheated.

Another challenge was concealing containment routes while ensuring future service access would not damage the timbers. For instance, positioning smoke detectors required planning to place supports without disrupting the exhibit.To minimise waste, a proportion of existing cast iron radiators and coolie light fittings were refurbished and reused wherever possible.

The project successfully combined heritage preservation with sustainability, achieving both carbon and financial benefits while safeguarding its historical significance.

Full design and acoustics for an exceptional new learning and events centre

A 1,550sqm building split over seven levels, designed as a flexible learning space. Natural daylight and ventilation, along with thermal mass ensure comfort while a closed-loop ground source system, partially powered by a PV array, provides efficient thermal management. Achieved BREEAM Excellent.

ORTUS is a new learning and events centre based in Camberwell, South London, adjacent to the world-renowned Institute of Psychiatry, Maudsley Hospital and King's College London. Striking architectural features and sustainable technologies underpin this learning environment, which houses teaching and conference facilities, a community café and exhibition spaces.

Conceived as a free-standing pavilion, the building features multi-functional spaces arranged at half-level intervals and connected through a central atrium. Strategic window placement and floor level offsets, allow natural daylight to flood the interior while managing solar gain to prevent overheating. To enhance comfort and efficiency, the building employs both manual and automated natural ventilation systems. Additionally, the use of profiled soffit and exposed fair-faced concrete brickwork maximises the benefits of thermal mass, further stabilising indoor temperatures and reducing reliance on mechanical cooling. 

A sophisticated closed-loop ground source installation with seven 120-meter vertical loops efficiently provides thermal management for both heating and cooling needs. This system is partially powered by a roof-mounted photovoltaic (PV) array, which contributes to the building's renewable energy supply. An integrated KNX system is employed to manage the heating, ventilation, and air conditioning (HVAC) systems along with lighting, ensuring precise control and optimisation of energy use throughout the building. 

Ortus achieved BREEAM ‘Excellent' and is EPC ‘A'-rated, ranking highest for sustainability among all National RIBA Award winners in the Architects Journal 2014. Beyond these credentials, the centre provides a flexible learning environment, promoting connectivity and community through thoughtful space planning and cutting-edge technologies, making it a truly holistic and forward-thinking space.

The first ‘eco-mosque’ in Europe, representing a new landmark standard for spiritual centres across the world.

The Mill Road site includes a 1,000 capacity prayer hall, community kitchen and café, teaching rooms and two residential units, all surrounded by a cypress tree garden, that provides a rich, naturally-cooled microclimate within the harsh urban environment.

We have been working over a number years on a rolling programme to upgrade the services, enhance the technical infrastructure and improve the thermal performance of the Grade II*-listed 6000m² Battersea Arts Centre, formerly Battersea Town Hall.
