No.14’s Portland stone façade has graced the north face of Cavendish Square for 250 years.
The Grade II listed building will enjoy a refined scheme, offering a unique combination of grand Georgian rooms looking south over the trees of the Square at the front, and modern open-plan offices behind.
The reimagined entrance hall will see the original stone and slate floor, plaster and timber details, and Adam fireplace each refurbished and restored to their period grandeur.
In addition to this, united by a soft palate of natural finishes, new bronze-accented arched openings will lead past the lift to the Mews access at the rear of the building.
The skylight above the grand central staircase will bathe the space in rich natural light. Elegant European light fixtures will adorn the ceiling and walls.
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.
Like many grand Georgian houses, the centrepiece of 14 Cavendish Square is its impressive top-lit stairwell.
The grand front room on the First Floor, the piano nobile of the building, enjoys ceiling heights in excess of four meters, providing the room with its perfect proportions.
Centred around three windows overlooking the square, as well as a carved fireplace, it is a room to inspire quiet awe.
The elegance of the front rooms lies not just in their perfect proportion, but also in the fine workmanship of the details.
Period plaster cornices, carved marble fireplaces, panelled and original plaster walls possess an authenticity that cannot be recreated.
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.
Leading off the grand front rooms are even larger, and equally tall, modern office spaces in the reconstructed rear of the building.
Full height glazing or tall sash windows look out onto planted courtyards and roof terraces.
A lighting scheme has been prepared by specialist designers, combining soft reflected light and direct desk lighting, all tailorable to the user.
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.
Even in its current state, the Third Floor is intensely atmospheric. The proposed scheme will seek to maintain this unique energy whilst restoring it in its entirety.
The reimagined top floor will be completely opened up, and will centre around a new glazed terrace looking out onto a full width green wall. The terrace will provide a calming breakout space.
In addition to this, new skylights have been incorporated into the scheme of works for the floor, allowing for ample natural light, making it a modern, bright and energising space.
Taking inspiration from the materiality of the original building, a harmonious contemporary material palette has been curated, in natural stone and brass tones.
In the scheme, an elegance of line provides continuity between the Georgian original, the 1950s reconstruction, and modern insertions.
Shallow domed lift lobbies are planned for all five floors, finished in Venetian plaster in flattering natural tones.
The interiors at 14 Cavendish Square will combine the elegance and craftsmanship of the original building with the best of modern design to create a workplace that people will want to work in.
The architects for the scheme have sought to exploit the best of each period: the panelling and fireplaces of the front of the building will be restored to give rooms of incomparable discretion and grandeur, while the rear rooms are designed to exploit the open plan and generous ceiling heights.
All spaces are designed to have a memorable character, from the grand entrance and piano nobile floors to the top-lit top floor.
The offices, whether the perfectly restored period rooms at the front of the building overlooking the square, or the clean lines of the expansive rear, are linked by common parts of equal consideration.
Materials include Portland stone floors, still quarried on the Isle of Portland just like the stone of the front facade, patinated bronze wall panels, and polished plaster to the new domed lift lobbies in each floor.
Everything is given equal care and consideration, to create an atmosphere of understated sophistication.
