ALTHEA ARCHITECTURE is available for new projects

Founded in 2025 and based in Hœnheim, near Strasbourg, Althea Architecture designs projects that tell a story — your story.
From private homes and collective housing to office buildings and renovations, every space they design becomes a unique expression, true to the people who will inhabit it.

Their Approach: Listen First, Create Second

Every project begins with attentive listening — to your desires, your lifestyle, and your inspirations. Then comes creation: sensitive sketches, immersive 3D models, BIM visualization — tools designed to help you experience your project before it’s even built. From concept to the final detail, they stand by your side. Because a successful design also means a well-managed construction.

Building the Future with Responsible Architecture

At Althea Architecture, they believe that architecture can be both beautiful and environmentally conscious. They promote bioclimatic design and energy-efficient renovation of existing buildings. To renovate is to breathe new life into old walls, preserving Alsatian heritage while anchoring it firmly in the future.

Deeply Alsatian, Boldly Contemporary

Rooted in Hœnheim, their practice is inspired by the Alsace region they know so well — Strasbourg, Illkirch-Graffenstaden, Haguenau, Sélestat, Saverne, Brumath, Ostwald... This intimate knowledge feeds their creativity. They love to play with traditional regional codes, reimagining them into modern forms that dialogue with the existing architecture — without ever distorting it.

Why Choose Althea Architecture?

Because your project deserves more than a ready-made solution. They advocate for bespoke architecture in Alsace — born from the meeting between your aspirations and their creative vision. With passion, precision, and boldness, they bring your ideas to life.
