ZAC des Clos Sports Complex

A team committed to a meaningful project

Global Performance Contract

This project is led by a consortium united by a common vision: to design a durable, high-performing facility deeply rooted in its territory.

Lead — Design & Build
GCC — General contractor

Architect
COSTE Architectures, assisted by

Atelier SILVA LANDSCAPING — Landscape

Cabinet ROUSSEAU — Cost consultancy

Engineering consultants

OTEIS — Multi-disciplinary engineering (civil works, MEP, environment, fire safety)

Acoustique Vivie & Associés — Acoustic studies

Operation & Maintenance

CRAM — Operator-maintainer integrated from the design stage

This consortium embodies one conviction:
a building's performance starts at the very first stroke, and continues in its daily use.

A building that makes sense

"Architecture is not everything; it needs an accord with the sky, a light, and even a virtue."

The Chartres sports centre does not merely shelter disciplines.
It proposes a way of inhabiting sport.

In the ZAC des Clos, a territory in transformation, it becomes a point of balance:
between city and landscape, between heritage and future, between matter and light.

For COSTE Architectures, every project is an opportunity to connect.
To connect uses.
To connect generations.
To connect the built environment to the living world.

A landscape stitch — a gesture of reconnection

The project sits in the continuity of the green corridor.

It does not impose itself.
It repairs.
It reconnects.

The soft pathways are extended, the urban leftovers requalified, and the forecourt becomes a beating heart connecting:

• The Maison Pour Tous des Petits Clos
  
• The future facility on the land reserve
  
• The outdoor sports areas
  
• The Henri IV school

The building acts as a delicate stitch in the urban fabric.
It brings together rather than fragments.

Earth and sky: an architecture in living tension

At COSTE Architectures, form is always born of meaning.

Here, the project is built around a fundamental duality:

The base — the anchor

Massive, protective, rooted.
It evokes stability, solidity, trust.
It speaks of the earth.

Built in biosourced wood-concrete, it embodies a concrete environmental commitment.
A robust, local and sustainable material — it bears witness to a responsible architecture, mindful of resources.

The boxes — the leap

Set on this base, the volumes rise.

Each sporting discipline finds its height, its breath, its light.

Like a suspended movement.
Like a jump, an impulse, a projection.

The massing becomes a celebration of the body in action.
Lightness answers gravity.

The architecture tells the story of the sporting gesture.

Light as living matter

Natural light is not a complement.
It is foundational.

The multi-sport hall opens to the south, protected by a controlled overhang.

The perforations filter the light like foliage.

The boxing room dialogues with the existing trees to the north.

The dance studio becomes a luminous, hushed and intimate cocoon.

The building captures the sky.
It tames the sun.
It breathes with its environment.

At dusk, it becomes a soft lantern in the neighbourhood.

A conscious materiality

The project cultivates an intentional sobriety.

Outside:

• Mineral and warm base
  
• Light metal cladding with high albedo
  
• Organic perforated mesh

Inside:

• Exposed timber roof structure
  
• Light laminated timber wainscoting
  
• Integrated acoustic treatment
  
• Coloured signage as a living punctuation

Timber, omnipresent, creates a calm and peaceful atmosphere.
It places the building within a biosourced, low-carbon and durable logic.

Performance and responsibility

Because integrative architecture does not stop at form,
the project incorporates operation and maintenance from the very beginning.

The maintainer is involved from the design stage.
The systems are designed to last.
Energy performance is monitored, measured and optimised.

This sports centre is designed to:

• Reduce its footprint
  
• Control its consumption
  
• Guarantee the durability of the equipment
  
• Offer well-controlled operating costs

Ecology is not a discourse.
It is a method.

A place that makes you want to come back

A sports facility is not just a functional volume.

It is a place of routine.
A place of learning.
A place of collective ownership.

It must be welcoming, legible, reassuring.
It must spark momentum.

The Chartres sports centre is conceived as a living building.
A building that inspires movement.
A building that connects bodies, the city and the landscape.

The values carried by COSTE Architectures

Constructive common sense

Territorial anchoring

Environmental sobriety

An architecture of connection

Justness of volumes

Attention to the living

In Chartres, these values take form.
Not in exuberance,
but in balance.
