What originally drew you to interior design?
I was always deeply affected by the feeling of a space and how the right lighting, texture, or layout could shift your mood. As a child, I constantly rearranged furniture and styled little corners, instinctively seeking balance. Over time, that instinct turned into a deeper appreciation for architecture and design. Interior design became a way to create meaning through atmosphere and comfort. It has always been about helping people feel good in their homes, and that still drives me today.
How would you describe your signature design approach?
I would describe it as quiet, considered, and personal. I never begin with a fixed aesthetic. Each project starts as a clean slate, and together with the client, we develop a design that reflects their lifestyle, preferences, and values. I place a strong emphasis on atmosphere, not just visual impact. I strive for interiors that are warm, timeless, and refined without being overly decorated.
You’ve completed over 400 projects. What keeps the work fresh for you?
The clients keep it fresh. Every person brings a different rhythm to their home, and no two lives are the same. I enjoy discovering what makes each household unique and translating that into a space that feels right for them. The trust that develops during the process is also very meaningful. That relationship, along with the creative challenge of starting from scratch each time, is what keeps the work interesting year after year.
You often speak about restraint as a luxury. Can you elaborate on that?
Restraint brings clarity. It invites peace and gives every piece of a room more presence. In a time where so much design feels driven by noise or excess, creating something calm and refined has greater emotional value. I believe when a space is thoughtfully edited, people feel more relaxed and grounded in it. That sense of ease and balance can be far more powerful than decorative flourishes.
How do you balance modern needs with the charm of older homes?
The key is to start by respecting the existing character of the home. Original ceilings, trims, floorboards, and proportions hold so much history. I always aim to preserve these where possible, then layer in contemporary comfort in a way that feels natural. Whether it’s integrating modern lighting or improving the flow, I ensure the changes support both the architecture and the way people live today. It should feel cohesive and quietly evolved.
What’s one mistake people often make when designing their homes?
Rushing the process or trying to fill a room with too much at once. A home needs to function well, not just look good. Often people focus only on how something appears without thinking through how it will be used or how it will feel to live with it daily. I advise clients to take their time, reflect on how they use the space, and allow the design to unfold with care.
How has your philosophy evolved over your 30-year career?
When I started, I was drawn to balance and proportion. Over time, I’ve come to focus even more on the emotional experience of a space. I pay close attention to how a home supports the people living in it, how it responds to light, and how it contributes to wellbeing. I’ve also learned the importance of restraint and allowing space to breathe. Good design grows with you. It’s something you feel, not just something you see.
What’s your favorite type of project to work on?
I’m especially drawn to homes with architectural heritage. They often have incredible bones and character that can be brought to life in a very subtle way. Restoring and updating them without losing their integrity is deeply rewarding. But I also enjoy any project where the client is engaged and interested in creating a home that reflects who they are. That collaboration is what makes the process fulfilling, regardless of the style of the home.
How do you stay creatively inspired?
Travel has always played a role in keeping me inspired. I love European architecture, especially Parisian design and Italian villas for their sense of scale and history. But more than that, I find inspiration in everyday life—conversations, nature, materials, art, and time spent with thoughtful people. I stay connected to what feels timeless and meaningful, rather than chasing newness. The best ideas often come when I’m simply paying attention to how people live.
What do you hope people feel when they walk into a home you’ve designed?
I hope they feel calm and welcomed. A well-designed home should create a sense of ease, where people can truly relax and be themselves. It should reflect the personality of the people who live there while also offering comfort and beauty. If a space encourages people to slow down, connect, and enjoy their surroundings, then I know the design has done its job.
