Battersea Arts Centre

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. 

British Academy

New spaces for the exchange of ideas and hybrid working at the Grade I-listed institution

 

Restoration of underused double-height basements created a new auditorium and three flexible event spaces with cutting-edge digital technologies for 220 people. Upgrades included remodeled WCs and improved ground-floor access. Energy efficiency was enhanced through new double glazing, low-carbon heating, and thermal zoning.

 

The British Academy is the UK’s national body for the humanities and social sciences – with a voice that champions the study of peoples, cultures and societies, past, present and future. Situated within the Grade I-listed Nash-designed Carlton House Terrace, the building lies between The Mall and Pall Mall in London’s Mayfair.

Skelly & Couch led the survey of existing services to plan diversions and demolitions of works alongside an extensive review of archive record drawings to understand the existing systems in place. New double glazing was installed, improving energy efficiency with a 40% reduction in heat loss. Natural ventilation was maximised by using direct connections to the outside for air paths.

Bespoke mechanical and electrical systems were designed to suit the building’s historical constraints. A reversible air source heat pump replaced gas boiler heating, providing low-carbon heating to the events spaces. This is facilitated by thermal zoning, a component of the new building energy management system which includes full fault diagnostics and energy sub-metering.

Heat reclaim mechanical ventilation enhances this setup by supplying filtered air while retaining most of the energy already used to heat the building. The auditorium ventilation system's design was carefully designed to align with the building’s architectural and structural needs without compromising its listed status. Additional energy-saving technologies include LED lighting with occupancy, daylight, and dimming controls, as well as low-flow water fittings to reduce hot water consumption.

The refurbishment of the lower floors of the British Academy marks a significant step in the Academy's mission to enhance both physical and intellectual access to the building, facilitating new conversations, new connections, and new ways of thinking within its historic walls.

 

Chichester Festival Theatre

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.

Command of the Oceans at the Historic Dockyard Chatham

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.

Covent Garden Opera Terrace Restaurant

The project involved the sensitive upgrade of an existing restaurant facility on Covent Garden’s famed Opera Terrace within the historic Grade II*-listed Market Building.

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 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 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.

2015 RIBA London Regional Award winner

Dorset Museum & Art Gallery

New spaces for four million objects.

 

Refurbishment and extension of the grade II-listed building in Dorchester's urban conservation area to create a ‘Collections Discovery Centre'. Basement archives rely on innovative passive climate control, while gallery spaces and workrooms use HVAC systems for controlled conditions.

 

The development created new facilities for display, education, research, and storage at the Museum, expanding opportunities for audiences to explore collections and stories while improving access, research potential, and public engagement. It also supports the local economy, tourism, and museum collecting capacity across Dorset.

The Museum holds around 4 million objects spanning Natural History, Geology, Archaeology, Social History, Costumes and Textiles, Photography, Literature, Fine Art, and Decorative Arts. Among its significant collections are the renowned UNESCO Jurassic Coast geology collection and a Thomas Hardy Archive listed on the UNESCO Memory of the World register. The Museum also features an extensive library, archive, and a dynamic temporary exhibitions programme in collaboration with national and regional partners.

The basement archives employ passive measures to maintain optimal preservation conditions. A highly insulated fabric minimises heat transfer, while high thermal mass materials stabilise temperature fluctuations. Hygroscopic materials regulate humidity, reducing reliance on mechanical systems. Where possible, natural ventilation enhances airflow, further optimising energy efficiency.
Gallery spaces and workrooms benefit from stable temperature and humidity through tailored HVAC systems, with full air conditioning in areas requiring even greater climate control.

Skelly & Couch collaborated with the Museum from the outset to develop an environmental control strategy balancing artefact preservation and operational efficiency. Their approach integrates recent research supporting stable conditions with minimal seasonal variation, mitigating extreme fluctuations to optimise conservation and climate control.
The development enhances public access to the Museum’s collections, deepens research opportunities, and supports the community, and enriches its the cultural and educational experience.
