NESTLED in the heart of Chelsea, Catherine Wilman Interiors led the design and project management for the complete overhaul of this opulent townhouse, incorporating a partially excavated basement for a cutting-edge kitchen renovation.


Our clients, Philip and Nicky, were searching for top interior design firms in London capable of tailoring a space to their unique lifestyle and prized collection of antiques and artwork. Luckily for us, they were drawn to our blend of classic and contemporary urban aesthetics, making Catherine Wilman Interiors their choice for this ambitious undertaking.

The basement's avant-garde design provides a striking counterpoint to the home's more traditional architectural elements. Anchored by a polished concrete floor, the space is centred around a sleek, white Boffi kitchen.


Maximising storage was a key objective, leading us to implement ingenious solutions like pull-out cupboards ingeniously tucked beneath the stairway. To balance the basement's ultra-modern feel, we integrated bespoke elements made of reclaimed wood, particularly evident around the minimalist fireplace and in the banquette seating areas.

By leveraging London's rich architectural history while incorporating state-of-the-art interior design features, Catherine Wilman Interiors delivers a seamless blend of the old and the new, meeting the highest standards of luxury and functionality. Whether you're located in the UK or aiming to introduce a dash of British flair to your overseas property, our one-stop design solutions are poised to exceed your expectations.

Another key design feature in the kitchen basement is the TV snug, including a fireplace and more storage using the reclaimed wood. There is also a new cloakroom that is in keeping with the modern minimalist feel of the kitchen but includes playful features such as the moulded concrete sink.

The master bedroom and dressing room have bespoke wardrobes designed specifically for the clients’ unique pieces and needs. Matching with the more classical aspects of the home the bespoke cabinetry has shaker-style door mouldings that continue onto a bay window seat with hidden storage. The wardrobe interiors are planned specifically to the clients’ clothing and shoe measurements and details such as drawer dividers and tie racks to ensure the best use of space. 


The bathrooms have a classical luxury interior design with a mix of stunning marble surfaces balanced with softer painted cabinetry finishes. With the use of Drummonds detailed sanitaryware, each bathroom

– while in the traditional style – has its own feel and aesthetic. The lighter tones of the Carrara marble in the master bathroom pairs beautifully with the pale French greys to create a tranquil atmosphere. The darker and more dramatic tones of the guest shower room are exaggerated with the moody blacks and panelled walls. ​

Drawing room & hidden snug

The snug was an interesting room to design as the clients’ brief was to have as much seating as possible in the enclosed space - which is hidden at the end of the hallway. Catherine Wilman Interiors designed an oversized, luxurious banquette seating as the focal point. The rich burgundy velvet draws the eye in and offsets the darker warm tones of the wall. This room packs a punch with another amazing design feature in the smaller room - the hidden bookcase door. To make the most of a smaller room rather than minimising the amount of bookcase storage Catherine Wilman Interiors decided to incorporate the door into a clever storage solution. The secret door is accessed from the hallway entrance, hidden in the panelling. 


The drawing-room was very specific to the client. The room is set apart from the rest of the house, in which it feels like walking into another world. The antique library features are designed to showcase collectables and unique antique pieces, from “Dorothy” shoes poking out between books and antique furniture every aspect of this room reflects the personality of the client which Catherine Wilman Interiors feels is so important when designing a home.
