My Vision of Architecture

To me, architecture isn't only about constructing buildings. It's above all about creating places to live that reconcile human beings with nature and its ecosystem. I believe a building should be alive, breathing with its environment, and should give the people who occupy it a sense of well-being, serenity, and belonging.

I've had the chance to put that conviction to the test on several architecture competitions won in recent years the OHADA headquarters in Yaoundé, the Sodecoton headquarters in Garoua, and the ASAC headquarters in Douala. Three different projects, three different briefs, but the same underlying demand each time.

The Office, a Place to Feel at Home

Today, we spend a large part of our lives in built spaces, especially in our workplaces. That's why I believe offices shouldn't be mere production spaces, but places where everyone feels at home. Architecture should foster comfort, creativity, exchange, and a balance between work and life.

That's exactly what we set out to achieve with the ASAC headquarters in Douala: an office building that doesn't just house workstations, but gives the people who spend their days there room to breathe.

Nature at the Heart of the Project

This vision calls for spaces that are broadly open to the outdoors, where natural light, air, greenery, and hanging gardens take center stage. Nature shouldn't be a mere decorative element; it should be an integral part of everyday experience. Everyone should be able to feel that closeness to living things, even at the heart of a city.

At the OHADA headquarters in Yaoundé, this takes the form of a planted atrium, open to the light, where you can run into a colleague between two meetings without ever losing sight of the greenery.

Building With One’s Territory

I also stand for an architecture deeply rooted in its territory. Every region has its own resources, materials, climate, and know-how. Rather than systematically importing materials from elsewhere, I want to favor what's available locally. Building with the materials of a place means reducing environmental impact, supporting local artisans, preserving traditions, and creating buildings that fit naturally into their surroundings.

That's the principle guiding Ecoranch3, a private project we're leading in an equatorial forest zone in southern Cameroon: thatched roofs, local timber, hand-built brick lattice screens — an architecture that doesn't try to dominate the forest, but to blend into it.

A Responsible Architecture

Tomorrow's architecture must also be responsible. It should respect the cycles of nature through rainwater harvesting, natural ventilation, the use of renewable energy, and designs that limit resource consumption. Every project should help protect the ecosystem rather than degrade it.

A Human, Sustainable, and Sensitive Architecture

« An architecture that no longer separates people from nature, but brings them together. »

My vision is one of a human, sustainable, and sensitive architecture. An architecture that no longer separates people from nature, but brings them together. An architecture that turns homes, offices, and public spaces into places where we live better, work better, and rediscover, every day, the essential bond that unites us with our environment.

I dream of taking part in building this new model of architecture: one that respects the Earth, values local cultures, and places human well-being at the heart of every project.
