The People Behind the Light

Maison Loucelle is built on two convictions: that beautiful lighting requires both vision and craft, and that the best work comes from people who trust each other completely.

We are a small, focused team. Two people, two continents, one shared commitment to quality that refuses to compromise.

Guillaume: Founder, Maison Loucelle

Guillaume grew up with a deep instinct for space and light. Long before Maison Loucelle existed, he was the kind of person who noticed when a ceiling fixture was five centimetres too low, or when the colour temperature of a bulb was working against the warmth of a room.

He trained as an engineer at ESAIP in France, spent time at the Fachhochschule in Konstanz, Germany, and worked at Porsche in Stuttgart, where precision is not a value, it is a habit. That formation shaped a way of working that is methodical without being rigid, creative without being careless.

Over the years, he renovated a series of apartments and houses himself, developing an intuition for the specific power of lighting within an interior. Not lighting as decoration, but lighting as atmosphere, the invisible architecture that determines how a space actually feels to live in.

He also designed and built a passive house in Loucelles, a home conceived from the ground up to last, to consume as little as possible, and to remain beautiful decades from now. The project was certified to the Passivhaus standard, one of the most demanding energy performance certifications in the world. It was built using ecological materials, timber, cork, cellulose insulation, and its solar installation means it produces more energy than the household consumes. This is what thoughtful construction looks like when an engineer and a designer are the same person.

In parallel, Guillaume has spent over a decade as an Airbnb Superhost, welcoming more than three hundred groups across multiple properties. This is the experience that keeps Maison Loucelle grounded. Every design decision is tested against a simple question: how will this feel to a guest who has just arrived, who is tired, who needs the room to do its job?

That question does not appear in technical specifications. It comes from living the hospitality experience, host and guest, over many years.

What Guillaume brings to every project

• Engineering precision applied to aesthetic decisions
• Direct experience of hospitality from the inside
• A rigorous, unhurried approach to quality
• The belief that a fixture must earn its place in a room

Lei 雷见娣: Sourcing Director, Guangzhou

Great design without great manufacturing is only half a story. Lei is the other half.

Based between Guangzhou and Jiangmen, two of the most important regions in the world for high-end lighting production, Lei brings twenty years of hands-on experience to every project Maison Loucelle undertakes. Her work has spanned prestige hotel commissions, large-scale institutional contracts, and private residential projects at the highest level of the market.

Twenty years in this industry means knowing which factories maintain quality standards under volume pressure, which materials perform over time, and which suppliers can be trusted when a project is complex and the margin for error is zero. It means having relationships that take years to build and cannot be shortcut.

Lei travels constantly across manufacturing regions, visiting workshops, reviewing samples, and maintaining the standard of production that Maison Loucelle's clients expect. She understands the details that determine whether a fixture will still look exceptional in fifteen years, and she knows how to source materials and production processes that make that possible.

What Lei brings to every project

• Twenty years of relationships in premium lighting manufacturing
• Deep knowledge of materials, finishes, and production quality
• Fluency in the full supply chain, from raw material to delivered fixture
• An exacting standard that mirrors Guillaume's on the design side

A Partnership Built on Alignment

Guillaume and Lei met through a shared professional interest in high-end lighting and discovered something less common than complementary skills: a shared set of values.

A commitment to honesty in business. A discomfort with shortcuts. A belief that the work must be excellent even when no one is checking. A long-term view of what a professional relationship should be.

The distance between Normandy and Guangzhou is real. The cultural differences are real. The challenge of communication across languages is real. What is also real is the quality of alignment between two people who approach their work the same way, carefully, rigorously, and with genuine care for the outcome.

This is the partnership at the heart of Maison Loucelle. Not a transaction between a Western designer and an Asian manufacturer. A collaboration between two professionals who have chosen to build something together.
