Set within a duplex penthouse in central London, this project focuses on a refined interior shaped by stone, light and proportion. Marble runs throughout the space, from herringbone floors to bathrooms and kitchen surfaces, giving the apartment a sense of material consistency and quiet luxury. Arranged across two levels, the layout balances open living areas with more private rooms, creating a calm and cohesive environment. The visual approach centred on movement through the space and close attention to surface detail, reflecting both the architectural structure and the high-end specification of the interior.
