Mosaic Architecture + Design, one of Scotland’s most experienced practices, is set to transform four banqueting rooms at the grand Royal Automobile Club Pall Mall clubhouse in London this summer.

The comprehensive refurbishment of the Segrave Room, the Mall, Small Mall and Committee Room, will follow Mosaic’s recent refresh and upgrade to the clubhouse’s Stewart, Mountbatten, and Terrace Rooms.

Nicola Bell, Chair of the Pall Mall Committee, said: “We have worked hard to retain the personality and character of the rooms, which are beautiful.

“We’re delighted that Mosaic’s designs consider the differing needs of daytime and evening users, especially with regards to lighting, and that artwork changes will be made to ensure consistency and complement the room themes.

“Mosaic’s enthusiasm for the project is palpable, and their efforts will ensure these spectacular rooms can be enjoyed for decades to come.”

Stephen Mallon, director of Mosaic Architecture and Design, said: “It is important to us to enhance rather than detract, so that interventions are rooted in meaning and appropriate for the spaces. Architecturally, we celebrate the rooms’ heritage in the designs, as well as giving each room a more distinct identity.”

Stuart Black, studio director of Mosaic Architecture and Design, added: “The main feature of the Segrave Room, in addition to its distinctive trophy cabinet, is the new carpet. The design motif was inspired by the front of Sir Henry Segrave’s famous Golden Arrow car. It is bespoke to this room, so it’s very special. We’ve ensured the green and gold scheme continues through the room, fine-tuned to suit the carpet design colourway.”

In addition, the chandeliers will be enhanced by plaster roses on the ceiling, new lighting will make the room feel warmer and there will be blinds installed behind the curtains, which will appear more contemporary without the pelmet boxes.

The Committee Room will benefit from newly integrated audio which will improve the experience for those using or hiring the room. Specialists are being brought in to restore the high-level gilt work and the chandelier.

“As in the Segrave Room, the main feature is the carpet,” said Black. “The laurel shape references the Committee Room’s intricate ceiling motifs. We are replacing the deep blue of the gallery space with off-white to better complement the rest of the room and extending the antique mirror panelling.”

Presenting a particular design challenge were the Mall Room and the Small Mall Room, which have a connecting door but need to keep their own identity.

“These two south-facing rooms will have the same look, but it will be nuanced,” said Mallon.

“A navy and neutral colour palette will make both feel bright and luxurious. They will share the same curtains, with different edges and different pelmet designs; both will have smart upholstered panelling.

“The carpet’s leaf-like motif references both the views towards St James’s Park enjoyed by guests in these rooms and their ceiling décor, while an elegant new bookcase for the Mall Room is being made from the same materials – rosewood and burr – as the reception desk, to ensure a harmonious Club experience.”
