Welcome to Atelier Illumen.
I am Isabelle Decallonne, a designer of unique stained glass creations.
In my studio, established in 2018, I combine traditional craftsmanship with a contemporary, timeless aesthetic.
Each stained glass window is a carefully composed work of art, designed to bring beauty and serenity to the most demanding interiors.
My passion for design and light arose from my Product Design training and was refined during specialized training at Atelier Mestdagh (Ghent) and the Anderlecht Academy of Fine Arts/Stained Glass Crafts Department.
Authentic craftsmanship, contemporary appeal.
Every new stained-glass window I design is a unique interplay of light, color, shape, and texture. With an eye for detail, respect for craftsmanship, and a contemporary design language, I create works that not only enrich a space but also leave a lasting impression.
Unique creations, sustainably crafted.
I enjoy custom work: designs always emerge in dialogue with the client, the space, and the desired feeling.
Abstract shapes, subtle color palettes, and an optimistic undertone characterize my style. Sustainability is essential: reclaimed flat glass is given a new life in my creations, without ever sacrificing elegance.
An investment in timeless beauty.
A stained-glass window is a prominent mood-setter that subtly becomes part of the backdrop in which life unfolds. At Atelier Illumen, we believe that authentic craftsmanship should be a source of daily wonder—today, tomorrow, and for generations to come.
Recent projects and their story
Would you like to have a personal consultation to discuss my approach? I’d love to. I look forward to creating something special, together with you and for you.
A stained-glass window is more than a work of art. It is light, emotion, and heritage—every single day.
