Vaulx Milieu After School Center by STUDIO90 – A Playful, Low-Carbon Architectural Landmark in Vaulx-Milieu

Located on the edge of the village stadium and the town center of Vaulx-Milieu, the Vaulx Milieu After School Center by STUDIO90 redefines what community childcare architecture can be. Completed in 2023 and spanning 225 m², the project transforms a simple functional facility into a vibrant learning environment centered on flexibility, sustainability, and child-friendly spatial identity.

Designed by Thibault Ottavy and Loris Vidal, the building extends an existing complex built from modular cells. Instead of merely attaching a new structure, the architects crafted an architectural object — a sculptural form that blends infrastructure, landscape, and playful design.

A Distinctive Architectural Gesture for Children

From the first glance, the after-school center presents a rhythmic sequence of arches, curves, and counter-curves. These forms are not just visual features; they define the building’s personality. The gentle, looping geometry creates a fun, familiar, and emotionally engaging universe for children, helping them navigate the space intuitively while also signaling that this is a place designed especially for them.

Large openings, soft silhouettes, and flowing transitions make the architecture approachable, while also reinforcing a sense of safety and welcome. As a result, the building becomes more than a facility—it becomes an inviting environment that encourages creativity and exploration.

Flexible Interiors for Evolving Activities

Inside, the project embraces modularity, allowing the learning spaces to adapt seamlessly to different activities throughout the day. The flexible interior layout enables the team to transform rooms from quiet study zones to active play areas, group sessions, or social workshops.

This multi-use adaptability not only supports varied daily programming but also extends the lifespan and relevance of the center as community needs evolve.

Sustainable Materials and Low-Carbon Construction

One of the defining strengths of the project is its low-carbon construction strategy. STUDIO90 integrates:

• Low-carbon concrete for reduced embodied emissions
• Wood wool insulation, ensuring natural thermal performance and acoustic comfort
• A dual-flow CTA system, enhancing indoor air quality and energy efficiency

These choices align with the municipality’s commitment to ecological responsibility, ensuring that the building performs efficiently while offering a healthy environment for young users.

Technical partners—including CTG (structure), COTIB (thermic and electrical engineering)—helped deliver a cohesive, high-performance design.

A Community-Centered Architectural Object

By positioning the structure at the boundary between the village stadium and the town center, the architects created a meaningful connector within Vaulx-Milieu. The building acts as a social hinge, serving children during school hours and fostering community engagement after hours.

Its bold silhouette and intentional siting turn it into a recognizable local landmark, grounded in functionality but elevated by thoughtful design.
