Clarges Mayfair

Clarges Mayfair is a new landmark development by British Land in the heart of Mayfair, close to Bond Street and overlooking Green Park. The prime residential-led scheme comprises 34 premium residences prominently located on London’s Piccadilly.

The bold mixed use scheme will offer 191,000ft2 of luxury residential, retail space, a private members’ club and library, plus parking and leisure facilities at ground floor and three basement levels. To the rear of the residential development, a separate commercial office building totalling 88,000ft2 will be constructed providing Grade A BCO compliant space.

British Land acquired the Clarges Mayfair site in 2012 with revised planning consent achieved the following year to increase the high-end residential element of the scheme. Since work began on site in 2014, the three existing buildings have been demolished and the construction of four new buildings is currently under way. The quality and uniqueness of the design has set a new international benchmark for residential development in London. The complexity of this scheme includes a key stipulation of retaining the existing private members club on the site until the completion of their new building. This has required the construction of the residential block to be split into two phases, calling for extremely close collaboration between engineers and construction teams involved in the project.

Advice and expertise across the board
Waterman was appointed to provide a multidisciplinary engineering service from inception, assisting with the planning process, detailed design and throughout construction.

British Land has a very clear ambition for all its developments in terms of quality, efficiency, sustainability and innovation. From the outset, all of these drivers helped to inform the design and construction process.

The introduction of Laing O’Rourke to the project team after securing planning consent enhanced this further through the adoption of their DfMA (design for manufacture and assembly) precast concrete systems within the structural design. Our structural engineers have worked closely with Laing O’Rourke to select the best DfMA products to deliver this complex project to the highest standards.


During the early stages of design, our building services engineers agreed with Laing O’Rourke the elements of the design where DfMA would be appropriate. This informed the team to enable them to develop pre-fabricated repeatable solutions, for example services cupboards. It also influenced the configuration of the primary services to enable modular construction. Examples include plant areas, risers and distribution routes.

Our building services engineers have carefully considered the high performance façades and buildings to include low energy technologies. CHP will provide the primary heating source with PVs generating zero carbon electricity whilst ground source heat pumps will provide cooling for the scheme. Furthermore, the high quality design will achieve 40% improvement over 2010 Part L regulations. The commercial elements are set to achieve BREEAM ‘Excellent’ rating, with the residential parts accomplishing CFSH Level 4 status.

The diverse range of expertise provided by our teams has also involved solutions for environmental, vertical transportation, fire risk and acoustics.

We are extremely proud to be playing a key role in this ambitious project which will result in a new landmark address in the heart of London.

The office element of Clarges Mayfair will complete in mid-2016, with the residential element completing in 2017.
