Our project story
No.1 Grosvenor Square.
Magnificent modern living.
London’s finest address.
Exclusive style and service.
No.1 Grosvenor Square is one of Mayfair’s most prominent buildings. It sits on the corner of Grosvenor Square and is known as London’s ‘most desirable address’. As a member of the expert design team tasked with transforming this building from the headquarters of the Canadian High Commission, we have played a proud part in what’s heralded as one of the city’s most sought-after luxury developments.

This was a high-profile project from the outset, and we knew that exceptional standards were a must.

We were challenged to create the flawless environment required for exceptional standards of living. Located in the conservation area of Grosvenor Square, it was vital to preserve the historic façade, while also delivering the infrastructure and layout required for exclusive future-proofed luxury. Our engineering solutions needed to allow for the most luxurious environment possible: from quiet, calm, expansive spaces and open-plan living, to bespoke interior accessories and extensive spa areas.
Best of both worlds
The Neo-Georgian façade was expertly retained, rebuilt brick-by-brick. Meanwhile, the remainder of the building was given grand new proportions, with raised ceiling heights and enlarged windows. We crafted a myriad of solutions to maximise the net saleable area for our client. By using CFD modelling we rationalised the huge open-plan apartments, ensuring safety alongside space. Riser dimensions were engineered to the absolute minimum resulting in a core depth that provided substantial gains in net saleable area for our Client.
Our services design was all about discrete integration: from aspirating smoke detection to ensure no visible detectors on the ceilings and fan coil units sized for near-silent operation, to bespoke heating controls and final accessories. At every stage, we looked for efficient solutions: a London Underground tube line below the site meant the entire building was constructed on acoustic isolation springs to avoid vibration and noise from passing trains. This left an undercroft beneath, which we identified as a location for primary services distribution, freeing up more vital space and delivering grand ceiling heights within the building itself.
Behind the scenes
No.1 Grosvenor Square flawlessly answers both the desire for a piece of London’s heritage and people’s expectation of the latest technology – a duo that can often struggle to go hand in hand. In each of the residencies our hidden solutions ensure residents enjoy world-class acoustics, air quality, water pressure and heating, all within a historic space. For people with the highest expectations, this is the next level in luxury living.
An oasis of calm in the heart of the capital.
