Mansion Flat Refurbishment, St John’s Wood NW8
High-specification refurbishment of a 2,400 sq ft mansion flat in a 1930s Art Deco block near Lord’s Cricket Ground. Complete interior transformation with bespoke joinery, underfloor heating and smart home integration over a 9-month programme.
Art Deco Elegance Meets Modern Living
This generous 2,400 sq ft mansion flat occupies the entire second floor of a handsome 1930s Art Deco block on a tree-lined avenue in St John’s Wood. The owner wanted a pared-back, elegant interior that honoured the building’s Art Deco heritage while incorporating the comfort and technology of a modern luxury home.
The existing layout included a warren of small service rooms behind the kitchen. Our design removed these partitions to create a single, expansive kitchen-dining space with views across the communal gardens, while retaining the formal proportions of the double-aspect drawing room and library.
With no structural alterations to the building envelope, the project focused on interior fit-out: bespoke walnut and lacquer joinery throughout, Calacatta marble bathrooms, wide-plank engineered oak flooring over underfloor heating, and a fully integrated Crestron smart home system.
The freeholder’s consent process required detailed drawings and material specifications to be approved before works could commence. Our team managed this alongside the building’s managing agent, ensuring zero disruption to other residents.
