What We Do
It Begins with Understanding
For over three decades, Janine Stone & Co. has designed some of the world's most exquisite residential interiors. It is only by truly understanding our clients — their tastes, their way of living, the moments they value — that it becomes possible to create spaces worthy of them. From the layout of rooms to the most refined finishes and custom detailing, we approach every project with precision, painstaking research and an unwavering attention to detail.
Detail is Design
Our team of highly skilled interior designers draws upon deep knowledge and experience spanning the full spectrum of styles, from classical to contemporary, in the UK and internationally. Whether we commission a master craftsman to produce bespoke cabinetry or detail a bathroom skirting in hand-finished marble, it is always the intricacies — like the uniqueness of a snowflake — that make a design truly singular.

Interior Design from the Outset
While our interior design service can be offered independently, what truly sets Janine Stone apart is the integration of interior design with our in-house architecture and construction management from the very earliest stages of a project. Our interior designers and architectural interior designers work hand in glove with architects and the construction team — not at the end of the process, but at its inception. We also work closely with lighting designers and landscape architects to ensure interiors connect seamlessly with their surroundings — from garden views and terrace planting to the atmosphere created by carefully considered light.
Discover our integrated approach
From Pied-a-Terre to Country Estate
Our portfolio spans expansive country estates, lateral apartments and penthouse residences in prime central London — Belgravia, Mayfair, Knightsbridge, Kensington, Chelsea, Holland Park — pied-à-terre, townhouses and private homes internationally. In the world of luxury interiors, projects of different size and scale are equally worthy of inspirational design and meticulous attention.
An Independent Service
While many clients commission our interior design alongside our in-house architects and construction managers, just as many engage us as their interior designers alone — taking full responsibility for every fitted and unfitted element of the home, from joinery, panelling and lighting to fabrics, furniture, art and accessories. Where a client already has an architect or main contractor in place, we are practised at dovetailing seamlessly into the existing team. The result is the same either way: a complete interior, considered to the smallest detail, delivered without compromise.
Furnishing & Installation
Three decades of work on the world’s most exceptional residences have given us a network few can match — tens of thousands of specialist suppliers, master artisans and craftspeople in the UK and internationally, and the contacts to find the rare and the unusual pieces that bring a home together. Once a design is signed off, our dedicated furnishing team takes over: every piece is ordered, tracked, inspected on arrival and held in our own central storage until the residence is ready to receive it. When the moment comes, every chair, lamp, cushion and finishing piece is installed by hand — so the client walks into a home that is complete from the very first day.
“The best interiors aren’t designed to be admired — they’re designed to be lived in, and to quietly improve the lives of the people who live in them.”

Client Presentations
Our presentations to clients are comprehensive — including 3D models you can explore from every angle, detailed elevations, joinery drawings and much more. Here we share three of the key elements delivered for each room: a floor plan, a furniture & finishes board, and a computer-generated image of the completed space.

Interior Design — Questions
Everything from first concept to the day you move in. Space planning, material and finish specification, lighting, bespoke joinery and furniture design, art advisory, soft furnishings, and final dressing. Clients can engage the studio for a single room, a full floor, or a whole-house scheme — whether as a standalone interior design appointment or as part of our integrated concept-to-completion service alongside our architects and construction team.
Yes. The studio is stylistically agnostic — we work in the language the house and the client call for. Recent projects range from Grade II listed Georgian restorations in Mayfair to fully contemporary new-builds in the Home Counties and internationally.
No. Interior design is offered as a standalone service and a large share of our work is exactly that — clients come to us with an architect and contractor already appointed, and we dovetail into the existing team to produce the best possible result. The integrated concept-to-completion service is an option when clients want it, not a requirement.
Yes. Even where a brief is predominantly interior — particularly the prime central London apartment work that often sits inside listed mansion blocks — our in-house architects can take on the statutory side: planning applications, listed-building consent, building regulations, party-wall matters, and landlord consent on leasehold apartments. The architectural and interior teams sit in the same studio, so coordination happens naturally rather than across firms. It is one less professional appointment for you to make and one less handover between disciplines.
The real starting point for us is fit. We focus on clients who want something original and considered, and who appreciate the value of genuinely high-end design and finishes. Project scale matters less than aspiration and quality — we are happy to take on smaller schemes where the ambition is there, and will decline larger ones where it is not. Fees are typically calculated as a percentage of the delivered scheme, set against a detailed scope agreed with you at the outset, and we provide a transparent fee proposal after the first meeting with no obligation to proceed. Smaller interior design schemes can start in the hundreds of thousands; whole-house projects involving bespoke joinery, fine finishes, furniture and art can rise into multi-million-pound territory.
Every project has its own timeline, shaped by its complexity, the scope of the works, and the client's priorities. We produce a detailed programme once the design direction is established and keep you regularly updated as the project progresses. Smaller commissions — a room, or a decoration-and-furnishing brief — typically run three to six months. More significant schemes involving bespoke joinery, structural work, or listed-building considerations can run to eighteen months, two years, or longer from first brief to occupation.
Yes. The studio advises on both, and works with established art consultants and dealers when a project calls for it. Clients can elect to be closely involved or to delegate entirely.
Regularly. London and the surrounding countryside — Surrey, Hertfordshire, Oxfordshire, Cambridgeshire — are our largest market, but the studio has delivered projects throughout the UK and internationally: North America (including New York), the South of France, Monaco, wider Europe, Scandinavia, the Middle East, Russia, and as far east as Hong Kong. We consider projects anywhere in the world if the fit is right.
