There is something wonderfully expressive about the work of Colette van den Thillart. Her interiors have a sense of confidence that never feels forced, balancing timeless elegance with a distinctly contemporary spirit. As the creative force behind NH Design and a designer recognised internationally for her sophisticated approach to residential and hospitality interiors, van den Thillart has developed a visual language that is rich in character, yet remarkably composed. Her spaces invite attention without ever demanding it.

At the heart of her work is a fascination with contrast. Refined architectural details meet unexpected colours, sculptural furniture sits alongside traditional forms, and luxurious materials are often given a playful twist. Rather than creating rooms where everything matches perfectly, van den Thillart embraces the tension between different elements. This creates interiors that feel layered and collected, with every piece contributing something to the personality of the space.

Colour is perhaps one of her most recognisable tools. Deep greens, warm terracottas, soft blues, dramatic jewel tones and unexpected neutrals appear throughout her projects, often working together in combinations that feel both adventurous and beautifully restrained. Yet colour is never used simply for visual impact. It helps establish mood, define spaces and create emotional connections, transforming an interior from a collection of objects into an experience.

Her approach to furniture is equally distinctive. Van den Thillart has an instinct for combining bespoke pieces with vintage discoveries and contemporary designs, allowing each interior to develop its own rhythm. Curved silhouettes, tactile fabrics, intricate detailing and statement lighting frequently become focal points, while smaller decorative elements provide moments of surprise. The result is a sense of luxury that feels deeply personal rather than overly polished.

What makes Colette van den Thillart’s interiors particularly memorable is their ability to feel glamorous and comfortable at the same time. There is sophistication in every proportion and material choice, but there is also warmth, humour and a genuine sense of livability. Her rooms are designed to be experienced rather than simply admired, encouraging people to gather, relax and interact with their surroundings. It is this human quality that gives her work its enduring appeal.

Ultimately, Colette van den Thillart demonstrates that contemporary interior design can be both sophisticated and wonderfully expressive. Her work refuses to be confined to a single aesthetic, instead finding beauty in contrast, personality and carefully considered detail. The spaces she creates feel like individual worlds, where colour, craftsmanship and imagination come together naturally. In an industry constantly searching for the next big trend, her work offers a more lasting proposition: interiors with a strong sense of identity, designed to be lived in and remembered.
