Creative, dynamic, solutions-focused
I really enjoyed working with Alexandra on the transformation of my two main living areas.
From our first discussion, I felt that she “got” me: understanding what I wanted, despite my own lack of firm ideas. She came up with imaginative and innovative solutions and I am delighted with the results.
Alexandra is highly energetic as well as creative, and I appreciated her dynamic approach in keeping the project on track and on time. I was glad I had opted for her highest level of service so that she managed the whole project closely, even putting together some furniture and hanging a few pictures herself. She has a great eye for styling: I was amazed – and pleased – at how good some of my things could look when placed well.
Overall, it was a great experience, and I recommend her wholeheartedly.

We’re so grateful to Alexandra for her amazing help in decorating our new flat. She brought so much creativity and expertise to the process, especially when it came to making the most of our space and figuring out the best layout for our furniture. What really stood out was how well she worked with what we already had like our colourful rug and helped us build a cohesive colour palette around it. She guided us on paint choices and small, impactful additions like cushions, which completely transformed the look and feel of our living room without breaking the bank. Alexandra was incredibly mindful of our tight budget and gave us thoughtful, affordable suggestions that made a big difference. She has a great eye for design and practicality, and her warm, friendly approach made the whole experience easy and enjoyable. Thanks to her, our flat now feels like a real home - stylish, comfortable, and very us. We couldn’t recommend her more highly! More...

"We recently moved into a new house that was pretty but old and aging. We wanted to make it feel like a Mediterranean home. We asked Belle & Cosy Interior Design to create it for us. Our initial idea was to stay with neutral colours but Alexandra suggested to instead add colours here and there. She was right! We couldn’t be happier with the end results. The use of teal, black and white colour now reflect our personality and with the advised adjustments we added also functionality to our living. It was so professional and committed from beginning to end and has been a pleasure to work on this project. Thank you Alexandra!" More...

As an East Sheen based Architectural designer I referred Alex to a local client whose project required a transformation without structural changes. Alex produced a wonderful scheme of finishes and colours that transformed the space, building on the furniture that the client already had and it looks super! So much so that the client used her on another property. Alex works well with the builders and communicates with all parties and subcontractors, effectively project managing. More...

Alexandra inspired and uplifted our style with fantastic results. It all began with a simple room – and suddenly the whole family was fighting to be in it. We love what she’s done and wouldn’t hesitate to ask for her advice again! More...

We had an incredible journey with Alexandra. As expatriates in France, following many years of living abroad in Africa, we were searching for a “French home away from home” that also reflected the unique experiences we’ve had so far. Alexandra managed to deliver the best possible experience, and we couldn’t be happier with the results. Highly recommended. Thank you, Alexandra! More...

What’s your interior design process?
I will visit in person or virtually your home, office or store and have a free consultation to understand your needs, look at the room(s) you would like changed and discuss your initial ideas.
This first visit will help scope the work, discuss your preferred style, your overall budget, and what you want to achieve. If you are the manager of a commercial space, we will audit your existing branding, positioning and potential marketing activity.
This first consultation is free. You only commit once you have agreed to the scope of work we will send you to approve, following our consultation.
Which interior design styles can you cater for?
I cater for all styles, as it is about creating interiors that reflect who you are and tell your story!
My style however is usually warm, layered, and eclectic. I blend rich colours —whether soft and muted or deep and vibrant—and textures with a cosmopolitan elegance, harmonising diverse influences to create interiors that feel soulful.
And as a mother of four, I also know beauty must meet function—real homes need to work, not just wow. I support on how to optimise the layout of your rooms and help design custom or off-the-shelf storage solutions that blend seamlessly into your space. My designs are thus practical and my interiors lived-in.
What do you love most about your job?
I absolutely love the way interior design can truly transform people’s lives!
What inspired you to start your own business?
I have always been passionate about interior design and have renovated or redesigned many properties I lived in or for friends. After 20 years working in the corporate world in marketing, I decided to make it my career.
Why should our clients choose you?
I’m a French interior designer based in Twickenham, who draws on a life lived between Paris, London, and Provence, with chapters in Brazil, the USA, and Finland. Each place has shaped my eye, but it’s your story I’m here to tell.
My aim is to help homeowners and busy professionals transform spaces that no longer feel like them—or that never did. Whether you've just moved, are navigating a life shift, or simply want to fall back in love with your home, I create interiors that reflect who you are and support how you live.
For commercial clients, I bring 30 years of senior marketing expertise to the table. That means I don’t just design beautiful spaces—I craft environments that embody your brand, speak to your customers, and support your business goals. When needed, I can even build your full brand and marketing strategy from the ground up.
Can you provide your services online or remotely? If so, please add details.
yes but nothing beats coming on site and meeting my clients face to face. Interior design is about YOU more than anything. So knowing my clients and their lifestyle will ensure I recommend the best design for them.
