The project was first conceived in 2007, co-ordinating with the design and eventual construction of the Elizabeth Line station beneath the site. As such, the building was designed to be flexible to adapt to changing market conditions across the long project programme. Sustainability is central to the design, with rooftop photovoltaic panels, a biodiverse trellis wall planted with wildflowers and a fully electric energy system.

Balconies and terraces with plantings offer outdoor meeting spaces and amenities are provided to support active and sustainable commuting, including secure bicycle storage, a repair station and premium changing rooms with showers.The material palette of terracotta, stone, and bronze responds to neighbouring historic buildings. The local streetscape is enhanced by a public art installation,Anatomy of Time, by Clare Twomey, which rises six storeys up the west faade, embedded in its terracotta louvres. It depicts ancient plants that once thrived in this area of Mayfair, and traces the path of the lost River Tyburn.Advertisement Source:Jack HobhouseArchitects viewWith 65 Davies Street, we set out to blend connectivity, sustainability, and architectural heritage into a seamless expression of contemporary workplace architecture. Having started the design over 15 years ago, to integrate with the Elizabeth Line station below, our challenge was to create a building of enduring adaptability and quality while setting new standards for sustainability and wellbeing.Our design reflects the areas legacy of terracotta faades, intricate craftsmanship and natural heritage. Clare Twomeys artwork, inspired by local flora, brings life to the faade, while native wildflowers climb a biodiverse trellis, linking the building to its natural context and adjacent green spaces. Inside, the lobby design celebrates the buildings connection to its context and history, integrating shapes from former building footprints in the finishes, carpets and furniture to create a tactile link to the past in a space that all users engage with daily. The materials help to maintain a dialogue with the buildings surroundings, using complementary materials and colours, including stone and bronze.We always set out to create exceptional places to work in. Office floors feature generous terraces, high ceilings, and openable windows that flood the rooms with natural light. These spaces are supported by top-end cycle facilities and changing rooms to promote healthy lifestyles. Through all these different initiatives, we were able to achieve WELL accreditation, BREEAM Excellent, and Wiredscore Platinum certifications.In 65 Davies Street, I think we have created a building that feels truly at home in Mayfair and that will contribute to the long-term success of this vibrant urban area.Ron Bakker, founding partner, PLP Architecture Source:Jack HobhouseClients viewOne of the best-connected offices in London, 65 Davies Street is a fantastic addition to Mayfair, blending heritage and modernity to create outstanding office space that blends seamlessly into its historic environment. Its testament to its design, amenities and the quality of the space that it was fully pre-let so far ahead of its completion.Alongside South Molton, the West Ends largest mixed-used development, and our transformation of Grosvenor Square into an extraordinary urban garden, 65 Davies Street forms part of a wider series of investments to ensure Mayfair remains a pre-eminent place for visitors, residents and businesses.Tom White, senior project manager, Grosvenor Source:PLP ArchitectureProject dataStart on site October 2021CompletionNovember 2023Gross internal floor area 9,058m2Form of contract JCT Design and buildArchitect PLP ArchitectureClient GrosvenorStructural engineer ArupM&E consultant ArupQS Gardiner & TheobaldProject manager Gardiner & TheobaldEmployers agent Gardiner & TheobaldMain contractor MultiplexFaade Thornton Tomasetti
