Marylebone remains one of central London’s most attractive postcodes, a chic yet quintessentially British neighbourhood, defined by its independent boutiques and upscale dining spots that are dotted along Marylebone High Street.
Step beyond it and the neighbourhood unfolds in a patchwork of Georgian townhouses, converted mews and garden squares. Unlike its neighbour Mayfair, Marylebone retains a more lived-in charm: locals browse the Sunday farmers’ market, explore local independent shops and stroll along the open green of Regent’s Park.
It’s precisely this appeal that shapes expectations of the homes here. In a market where prospective buyers and residents expect properties to function as beautifully as they look, choosing the right design or renovation partner carries real importance.
In this guide, we highlight some of the best Marylebone interior design firms and studios.
Accouter
Since opening its London interior design studio in 2012, the internationally award-winning Accouter has transformed properties for high-profile clients around the world and offers a full-service and highly bespoke approach to interior design and architecture. Its process begins with a thorough in-person consultation to understand individual lifestyle and tastes, before proposing a concept. From there, the team provides interior architecture, full interior design services, bespoke furnishings and art acquisition.
Accouter describes itself not as a purveyor of a fixed house style but as a creator of unique, individually curated spaces, often sourcing furniture and art globally to reflect each client’s personality. Project management is integral to the service and once designs are agreed, the team coordinates delivery, procurement and installation, handling every detail from materials to finishes.
Lewis & Co
Established in 2010, Lewis & Co is a full-service interior design, architecture and project management studio, recognised by the client-led Best of Houzz award program for its highly rated residential and commercial work. The firm creates elegant and modern interiors for its clients, working from offices in Marylebone and Sitges near Barcelona. Visitors can explore furnishings and design consultations supported by a network of UK and European makers who produce custom pieces to client specifications.
The studio designs high-end private residences, from country homes to city pied-à-terres, developing schematic design, interior architecture and bespoke furniture plans that reflect each client’s aesthetic. A recent project at Chiltern Court in Marylebone illustrates this approach with an inviting entrance hall featuring restored wooden floors and a console from the Lewis & Co Metal Collection.
Callender Howorth
With more than two decades of expertise, Callender Howorth specialises in creating luxurious and bespoke interior design for residential and commercial spaces in London, with a particular focus on neighbourhoods such as Marylebone. Founded in 1997, its services span custom furniture design, full-scale renovations and complete property transformations delivered by an experienced design team.
A notable project near Regent’s Park involved transforming a cobbled mews property into a contemporary home featuring a ground-floor swimming pool visible from multiple levels and accessible directly from the primary bedroom. Spanning three mews houses and fitted with advanced technology, the residence includes bespoke gull-wing windows that open dramatically to the sky.
The Stylesmiths
The Stylesmiths work across a broad spectrum of interior projects, from single-room revamps to whole-home refurbishments, as well as commercial offices, retail spaces and hospitality venues. Their published scope includes kitchen and bathroom renovations, furniture and lighting selection, colour and texture planning, storage solutions and full project management.
Clients begin with an initial consultation to define the brief and overarching vision. From there, the studio develops design concepts for approval, then oversees the project through to completion. A key point of difference is the three-tiered service model, which allows clients to choose the level of expertise that best suits the scale and complexity of their project. This flexibility appeals to clients seeking polished results and reliable project management without the ultra-bespoke approach of high-end studios.
Fresh Home Interior
Fresh Home Interior was founded by Ukrainian architect Anna Istomina, who opened her first design studio in 2008 and has since overseen more than 300 projects. After relocating to England, she established Fresh Home Interior in London, where the studio entered a new stage of growth, working with a global client network.
As a luxury interior design practice, the firm focuses on creating personalised spaces that balance comfort, functionality and style. It takes a collaborative approach, developing cohesive design plans that reflect each client’s taste while drawing on local influences and contemporary design trends. Services range from initial consultations to full project management, with careful material and furnishing selection that reflects the studio’s reputation for quality.
Marylebone Interiors
Marylebone Interiors is well suited to the area’s many older properties that require restoration, structural work or sensitive updates. The company was founded by Jon Ward, who began his career as a heating and plumbing engineer in 1986 before launching his building firm in 2001. Over the past 14 years, Ward and his team have earned a strong reputation for reliability, handling everything from full refurbishments, extensions and attic or basement conversions to heritage restoration and general maintenance.
Their expertise covers not only cosmetic improvements but also structural and technical work, including plumbing, historic building requirements and heritage preservation. The firm has a proven track record of resolving complex renovation challenges, such as integrating modern systems into older infrastructures.
Collectively, these studios reflect the calibre of design expertise available in Marylebone and what living in the neighbourhood demands. That is, interiors that respect the area’s architectural character while supporting the realities of modern life. With so many capable firms on the doorstep, homeowners have a strong foundation for creating spaces that feel authentic to the buildings they inhabit yet entirely their own.
