Interior design of an apartment at Twenty Grosvenor Square


We have created a refined aesthetic for the three-bedroom apartment. The vast interiors of the triplex home spans 5,863 sq.ft., and features a private double garage in the basement, as well as an in-residence elevator, for utmost privacy and ease in transition between each floor.

Formal reception room

Designed to embrace the heritage of Twenty Grosvenor Square, we sought to bring a sense of sophisticated opulence to the interiors of this apartment. A rich palette of blues is used throughout, while contrasting textures and finishes create exquisitely tailored spaces that are warm and inviting. Leading to the classical drawing room is a statement staircase adorned with floor-to-ceiling mirrors and a large pendant with brushed brass detailing designed by Lee Broom. Soaring ceilings and double-heighted windows create a light and airy atmosphere. The choice of materials sees an unrivalled elegance in traditional craftsmanship, including the polished statuario marble fireplace, woven leather consoles, and a rug from Stark.

The lower level holds three-bedrooms, including the master-bedroom with two dressing rooms and a master ensuite bathroom. The soft base palette of the master bedroom is layered with pink elements, complementing an upholstered headboard featuring an intricate mix of blue and grey tweed with leather piping.

Signature bar and games room

Contrasting to the upper levels, the interiors of the basement floor are inspired by more playful and unexpected aesthetics. A second entrance leads from the double garage to a hallway clad in a bold geometric patterned and taupe wallpaper, where dramatic uplighting provides the all-important sense of arrival for guests. The signature entertainment space is the Games Room which features a high gloss walnut chess board from Sir William Bentley, a full-sized pool table and a home entertainment system. One of the stand-out design moments providing an element of theatre includes a window adorned with sumptuous Dedar red velvet curtains overlooking the double garage which has grey wool wallpaper in a men’s suit style pin stripe. The double garage has been designed to be part of the apartment.

An antique mirror displayed above a Nero Argento marble-topped bar offers the ideal place to store and display the shaken or stirred martini. Black and white photography depicting classic cars are dotted throughout, and a smart but relaxed, modular seating area with leather piping creates an intimate and changeable setting.
