Success Case
The OWO and Raffles London
DAS & Small Cells
Located in the heart of Whitehall, the Old War Office is a Grade II* listed building that’s been meticulously restored and extended. Renamed The OWO, this landmark destination houses an iconic 120-bedroom Raffles Hotel, 85 luxury private residences, boutique shops, and more. Alongside powering commercial operations across the site, providing fast, consistent and reliable 4G voice and data coverage is essential for delivering the seamless connected experiences guests, visitors and residents expect.
The highly dynamic nature of the project required close collaboration with multiple specialist contractors throughout the 8-year renovation programme. Coordination was key and the Cellnex UK team had to work in a highly proactive and iterative way. This flexibility was particularly important in reducing project disruption during the COVID-19 pandemic.
Challenge
Constructed of Portland stone, the 760,000 sq ft mixed use site features a four-storey basement extension, rooftop terraces, a cinema, spa and swimming pool. Delivering connectivity at scale and across all these indoor areas was a complex proposition – particularly in underground spaces such as the Whitehall Ballroom, London’s largest subterranean ballroom, as well as into the two car lifts used to transport vehicles and large production sets direct from street level into the hotel’s underground event spaces.
Solution
Ultra-fast voice and data connectivity for guests, visitors and staff.
A multi-network operator solution.
Future-proofed infrastructure, featuring an upgrade path to 5G.
Seamless cross-site coverage in all indoor areas, including the hotel’s subterranean 600 capacity ballroom, nine restaurants, three bars, and 85 private residences.
A fully supported and managed solution.
