The recent completion of The Arc, a state-of-the-art outdoor sports centre within Homes England’s expansive Brookleigh development in Burgess Hill, Mid Sussex, signals more than just an investment in community wellbeing; it marks a significant triumph for the sustainable woodworking sector and Modern Methods of Construction (MMC). At the core of this expansive 8.6-hectare project—which includes multiple artificial and natural turf pitches—sits the timber-frame changing pavilion, a net-zero in operation facility that is quickly becoming a blueprint for future low-carbon public infrastructure across the UK.
The facility’s centerpiece, a purpose-built changing pavilion, was designed and constructed by modular specialist TG Escapes. By leveraging prefabricated timber-frame systems, the project moves the narrative of community building away from traditional high-carbon methods and firmly toward a bio-based solution rooted in wood product innovation. This approach provides not only a warm, inviting space for athletes and the local community but also a powerful case study in whole-life carbon reduction. For the woodworking and manufacturing industries, the Arc pavilion represents the culmination of sustainable design principles. The choice of a timber frame over conventional materials like steel or concrete was a strategic decision driven by the UK’s urgent need to address embodied carbon—the emissions associated with the materials, construction, maintenance, and disposal of a building.
Wood, sourced from sustainably managed forests, offers two critical benefits that metals and mineral-based materials cannot match: carbon sequestration and a vastly reduced manufacturing footprint. As trees grow, they naturally absorb and lock away atmospheric carbon dioxide. By using timber in construction, the carbon remains stored within the building fabric for the structure’s lifetime. Research consistently shows that using wood products can reduce the embodied emissions of a single building by 20% to 60%.
Furthermore, the natural thermal properties of the timber frame system contribute directly to the building’s operational efficiency. Wood is a natural insulator, providing up to 400 times more thermal efficiency than steel and 10 times more efficient than concrete. This inherent ability to retain heat and minimise thermal bridging is fundamental to achieving the facility’s net-zero operational status, drastically lowering the energy demand required for heating and cooling. This ‘fabric first’ approach ensures that energy-saving is built in from the ground up, reducing long-term running costs for Mid Sussex District Council and Places Leisure, the facility operator.
The modular timber frame system
The rapid delivery and high performance of the pavilion were enabled by the principles of modular construction. TG Escapes employed an advanced, panelised timber frame system, manufactured off-site in a controlled factory environment. This approach, which significantly increases the Pre-Manufactured Value (PMV) of the asset, provides substantial advantages over site-intensive construction:
The finished pavilion integrates four Sport England-compliant changing rooms, officials’ facilities, kit stores, and a reception area. Its warm, biophilic design—characterised by natural light and eco-friendly materials—seamlessly integrates the structure with the surrounding natural turf pitches and the broader landscape of the Brookleigh development.
The Arc project, procured via the UK Leisure Framework by Mid Sussex District Council and Alliance Leisure, and overseen by Homes England, serves as a powerful example of how public sector partnerships can drive the adoption of sustainable construction methods.
Councillor Robert Eggleston, Leader of the Council, highlighted the project’s success, noting that it is “a testament to what can be achieved through strong partnerships and a commitment to community development.” For the timber industry, this partnership validates the business case for wood-based MMC in significant public projects. The part-funding secured through Section 106 developer contributions ensures that local growth directly supports this low-carbon facility, creating a shared sense of community ownership and environmental responsibility.
As the UK strives to meet its ambitious 2050 net-zero targets, the demand for verified, high-performance timber solutions is set to soar. The net-zero timber-frame pavilion at The Arc, Burgess Hill, sets a new performance benchmark, proving that high-quality, durable, and aesthetically superior community buildings can be delivered quickly and cost-effectively using advanced wood-based manufacturing systems. This successful delivery by the wider project team, including S&C Slatters, AtkinsRealis, and Hadron Consulting, alongside the specialised craft of TG Escapes, positions timber and modular construction as the essential path forward for sustainable infrastructure development in the UK.
