Transforming Two Pavilions into Tropical Greenhouses

The Directorate of Green Spaces and Environment (DEVE) of the City of Paris entrusted us with the renovation of pavilions 12 and 14 at the Parc Floral de Vincennes, with the objective of transforming them into tropical greenhouses hosting new botanical collections.
– Pavilion 12, formerly dedicated to green walls, becomes the “Accrobranchées” space.
– Pavilion 14, previously devoted to camellias and ferns, becomes the “Jurassic” universe.

Adapting the Envelope to Climatic Requirements

The renovation focuses on modernizing the building envelope, installing a thermal and hygrometric regulation system, and implementing a floor adapted to the specific plantations of tropical collections.
The entire project is part of a High Environmental Quality (HQE) approach, aiming to recreate stable and controlled climatic conditions conducive to species conservation and public reception.

Technical Performance Serving Life

Emphasis is placed on several environmental performance levers:
– optimized heating and insulation,
– rainwater harvesting for irrigation and propagation areas,
– enhanced natural light input,
– controlled air quality through fine humidity regulation.

A Respectful Integration into the Site

The landscape integration of the two pavilions respects the park’s visual identity, with a strong desire for formal continuity between the new and old buildings.
The original roof overhangs are preserved, the shingle roofing extends to the existing walkways, and the hip roofs are now unified by a polycarbonate covering.
Finally, the vegetated surface treatment of the shingles reinforces visual continuity with neighboring pavilions, themselves largely integrated into the Parc Floral’s plant landscape.
