Welcome to 14 Cavendish Square. A contemporary office space from 1770. An opportunity to pre-let a remarkable central London head-quarters ready to be tailored to your needs.
Built at the height of London’s Georgian era, on one of its grandest sites, no.14’s Portland stone façade has graced the north face of Cavendish Square for 250 years.
The Grade II listed building will provide over 7,000 sq ft of net internal Grade A office space, as well as the option of a separately-accessed studio in the Mews of 1,205 sq ft at the rear.
A refined scheme has been prepared, offering the unique combination of grand Georgian rooms looking south over the trees of the Square at the front, and modern open-plan offices behind, with three outdoor spaces.

“To spend time in this building, to sit beneath its soaring ceilings, to watch the passing of sunlight through the day, the leaves through the year, knowing that all London has to offer is just outside the door, is an incredible experience.”

SEEN FROM CAVENDISH SQUARE
Each of the building’s five floors have been carefully stripped to their core in anticipation of the proposed scheme of works. This has revealed a rich patina of history as well as the graceful proportions of the existing interiors. The rawness of broken plaster walls and ceilings, exposed stone floors and open space, provide a canvas of unique potential for the impending development.


A commitment to quality and sophisticated design runs throughout the proposed scheme, in a palette of natural materials, tactile and expressive of quality.
For 14 Cavendish Square, architect Walker Bushe’s commitment to elegant and sustainable modern architecture has been coupled with William Smalley’s refined sensibility. Together, they have produced a scheme of works which will revitalise the listed building.
In the scheme, an elegance of line provides continuity between the Georgian original, the 1950s reconstruction, and modern insertions.

LITHOGRAPHS
The building was developed as one of four mansions by Sir George Foster Tufnell in 1770, and was built in two pairs, each boasting a grand order of Corinthian pilasters beneath matching pediments. Together they form one of London’s great architectural façades.
Having sustained bomb damage during the Second World War, the rear of the buildings were carefully rebuilt in the early 1950s, during which they were connected by a graceful arch over Dean’s Mews which runs between them. One of the city’s finest public sculptures, Jacob Epstein’s Madonna and Child (1950-52), was commissioned to adorn the archway.
Plans have recently been approved for the modern car park under the Square to undergo a £200 million redevelopment into a luxury shopping and wellness centre, continuing its history into the twenty-first century.

Jacob Epstein’s Madonna and Child, 1950-52 was commissioned to hang over Dean’s Mews facing Cavendish Square. It was cast from no.14’s roofing lead, recovered as a result of bomb damage to the rear of the building sustained during the Second World War.

Currently home to an underground car park servicing Cavendish Square, the Square itself is set to be transformed with a £200 million subterranean redevelopment by the Reef Group.
Housing wellness and healthcare facilities, alongside shopping and leisure spaces, the four-storey underground development will make the space “one of London’s premier public destinations for businesspeople, visitors and local residents to enjoy”.
This, alongside the further redevelopment of neighbouring buildings, is set to transform the immediate area into an ultra-contemporary hub for business, finance, design, medicine, and high-end retail.
Floorplans
The Lower Ground Floor provides 1,421 sq ft of modernised office space and uncompromised ceiling heights. It will enjoy new sightlines throughout its common areas which will be laid in Portland stone. The floor’s rear office will benefit from floor-to-ceiling windows at its far end, overlooking a curated green space.

The Ground Floor’s 1,216 sq ft of space boasts various original elements in its marble flooring, cornices, fireplaces, and grand central staircase. In addition, new sightlines will be created throughout the common areas, which in turn will be adorned with bespoke European light fixtures. The rear offices will boast floor to ceiling glass windows due to look out onto a courtyard bedecked with greenery, whilst the front office enjoys direct views onto the Square.

This extraordinary 1,410 sq ft floor offers magnificent views of the Square to the front, whilst a stunning open-air terrace is planned to the rear. The ceiling heights are in excess of 4 meters, and the front office possesses an original Georgian fireplace and detailing.

The Second Floor provides 1,410 sq ft of contemporary office space with superior views of the Square to the front.

This floorplate, due to be completely opened up, is 1,334 sq ft in size, and will be bathed in natural light from all sides. Floor-to-ceiling glass windows will wrap around the landscaped courtyard outside, and additional skylights are planned for the vaulted front ceiling.

The magnificent central stair rises past two landings to an elegant skylight, some 40’ above.
The staircase itself is in fact a fine recreation from the 1950s, built in concrete after the stone original, with a mahogany handrail and faithful replica of the fine wrought iron serpentine balustrade.

14 Cavendish Square will offer three outdoor spaces:
A central planted courtyard, between the main building and the rear Mews, providing calming views and natural light via tall sash windows to both the Lower Ground and Ground Floors.
The First Floor rear terrace, shown here, is ideal for outdoor meetings and summer drinks. The garden will be beautifully planted.
A lightwell around the main stair skylight on the top floor is to be fully glazed, and planted with a full width green wall.
