Key to creating the atmosphere the owners wanted was also recalling details they had loved about their previous apartment in the building. Conversations often returned to the bathrooms, which they remembered for their interwar elegance, with nickel plated Art Deco fittings, and Cararra marble floors with inlaid borders. In place of a bland contemporary bathroom, the project became an opportunity to reinterpret these details in a more contemporary fashion. Terrazzo with Carrara aggregate was selected as a more sustainable alternative to newly quarried stone, with the border introduced in a complementary green terrazzo. Nickel fittings were selected from Lefroy Brooks' 1930s inspired Mackintosh range, while a reeded glass screen, evocative of the period, allowed the shower to extend over the window, and generously stretch the full width of the room.

The apartment's kitchen tells a different story. Mansfield Street was originally designed without kitchens at all, as residents were served by a basement restaurant. When the restaurant later closed and was converted into flats, apartments throughout the building had to awkwardly accommodate kitchens in space never intended for them — in this case, a former maid's bathroom. This arrangement functioned poorly, with a galley kitchen entered from one side. Instead, the room was subtly enlarged and the doorway centralised, creating a more balanced arrangement, and establishing a long axial view from the terrace doors, through the sitting and dining rooms, and onwards to the kitchen window beyond. The kitchen itself was designed by Artichoke, while handmade tiles sourced by the owners during a trip to Paris create a personal and colourful feature in the space.
