Featured in the latest issue of Christie’s Real Estate Belgium Brussels’ Estates & Collections magazine, this interview with Tristan Montabord-Marc, an interior designer, explores an approach to high-end residential design based on restraint, durability and precision.

For several years now, Tristan Montabord-Marc has been developing a rigorous approach to high-end residential design, in which structure, proportion and materials take precedence over ornamentation. Through his eponymous studio, he designs interiors built to last, based on a careful analysis of how spaces are used and a constant quest for balance. His projects, carried out in Belgium and internationally, are characterised by a restrained and precise design language, where every decision is driven by the overall concept rather than by formalistic showmanship.

Located on the famous Avenue Louise, his studio functions as a space for reflection rather than a showcase: a place where light, textures and volumes interact in a restrained manner. Each project is conceived as a patient process, attentive to the daily routines and rituals of those who live there. Far from seeking spectacular effects, he develops an architectural language in which materiality, precise proportions and the quality of craftsmanship form the foundation of every project. This approach favours continuity over disruption, and coherence over a visible signature.

To mark the launch of the first issue of the Christie’s Real Estate Belgium Bruxelles magazine, we met Tristan Montabord-Marc at his Brussels studio to discuss his vision of understated luxury, the intangible value of a well-designed interior, and the underlying reasons why certain places seem to stand the test of time so effortlessly.

Interior architecture is often confused with interior design. What, in your view, is the fundamental difference?

People often confuse appearance with structure. Interior architecture is not about decorating a space, but about organising its invisible elements: proportions, circulation, light and acoustics.

It is a subtle design that gives the space its character and its ability to embrace life, without ever seeking to make a splash.

What is the most common mistake you see your clients making?

Wanting to start with an image. Choosing a style before understanding what the space is meant to facilitate: finding oneself, breathing, entertaining, working. When you start with the ways the space will be used, the aesthetics become a natural consequence, not a forced concept.

What distinguishes a simply high-end approach from a truly luxurious one?

High-end products boast certain qualities. Luxury, on the other hand, is characterised by restraint. It avoids ostentation and instils a sense of permanence and calm. It is evident in the details, in the overall coherence, and in the fact that it does not seek to impress.

Why do some places age better than others?

Because they aren’t designed to make a splash. They are built on a simple structure, using materials that stand the test of time, and making choices that aren’t dictated by trends. Here, patina isn’t a sign of deterioration: it becomes a testament to life.

Is your work more about taking away than adding?

Often, yes. To remove is to make the space legible. To eliminate visual clutter, simplify the forms, and clarify the circulation patterns so that the space breathes with precision and coherence. I rather like the idea that an interior should become a calm presence, not a performance.

At what point does a place cease to be merely decorated and become a place where people live?

When it flows. When you no longer need to think about the space in order to live in it. Everything is in its natural place. The interior is no longer merely an image: it becomes an anchor. It is at this precise moment that architecture ceases to be mere décor and becomes a framework for living. It accompanies without imposing itself; it supports our movements without constraining them. This masterful discretion is, in my view, the most accomplished form of contemporary luxury.

At a time when imagery reigns supreme, Tristan Montabord-Marc advocates an almost silent approach to interior architecture. It is a discipline that does not seek to entice, but rather to structure, to soothe, and to ensure a space stands the test of time.

In his projects, luxury does not make a show of itself; it is incorporated with discretion and precision, until it becomes an integral part of the space, enhancing it and consolidating its value over time. This subtlety, imperceptible at first glance, shapes spaces capable of standing the test of time without losing their coherence or intensity, and of ensuring that every interior forms part of a lasting legacy.
