Kingfisher Louvres chosen for prestigious Mayfair development

Kingfisher Louvres has delivered more than 600 acoustic louvre modules and 1,600m of screening louvre blade for a new mixed-use redevelopment project incorporating a luxury hotel in London.  

Facing the Ritz and located within the Mayfair conservation area, One Berkeley Street is a 19,500m2 development that includes the first 1 Hotel outside North America along with offices and retail units. It was formed through the refurbishment of two 1970s buildings and retains much of the original structure, creating a vibrant, modern building that is sympathetic to its past. The extensive development, delivered by DE Group Contracting, Kingfisher Louvres’ client and main contractor, features three new extensions including a two-storey rooftop extension.  

Kingfisher Louvres’ Technical Sales team collaborated with architects from Allford Hall Monaghan Morris to create a solution to screen the plant equipment situated on the roof and to also provide effective sound attenuation to minimise the noise from the HVAC systems. Kingfisher KA acoustic louvre modules, which provide permanent ventilation combined with the reduction of airborne sound transmission into or out of buildings, together with the company’s KC120 screening louvres, helped provide the perfect blend of acoustic performance and screening. 

A total of 646 acoustically treated aluminium louvres – a mix of KA150/20 modules and KA270/20 modules – were supplied in RAL 7047 matt at different depths to meet the varying sound attenuation requirements for the building. Bespoke penetrations were also required through some of the acoustic louvres on the roof to allow for a man-safe support system – therefore, each penetration needed a specially designed unit.  

On the roof of the development, Kingfisher’s KC120 screening louvres were installed to form several plant screens alongside 10 single doors for access to plant equipment. The KC120’s Z-profile blade can be angled upwards or downwards for screening from any angle. 

With the project requiring so many bespoke elements, a dedicated assembly line was set up within Kingfisher’s Nottinghamshire factory. The deliveries also had to meet stringent timescales due to the restrictions of the busy Central London location. 

Darren Rees, Project Manager at DE Group Contracting, commented, “This was a complex louvre installation on a very prestigious project. Not only did the louvres have to provide sound attenuation and screening for the plant equipment, they also had to fit with the architectural aesthetics of the development, as well as incorporating a specialist man-safe system which added to the stringent level of detail that was required. We were delighted with the technical and logistical support provided by Kingfisher Louvres throughout the project and the subsequent quality of the installed louvres.” 

The project won the Best Mixed-Use Scheme at the Building London Planning Awards in October 2024.
