L’Arbre Blanc - Montpellier

Project data

 

“L’Arbre Blanc”, Montpellier’s new architectural icon on the banks of the River Lez near the university library, towers over the city at 56 metres. All the occupants and visitors of the city can enjoy unique sweeping views of Montpellier.
 
The mixed-use residential building is home to 120 apartments, an underground car park, a panoramic rooftop bar, a restaurant and a gallery.
 

  • Joris Ide Product: JI Vulcasteel Roof – 80mm for the balconies

  • Surface area: 4000 sqm of mineral wool core panels

  • Principal: Proméo Patrimoine, Opalia, Evolis Promotion, Crédit Agricole Languedoc Immobilier

  • Architects: Nicolas Laisné Architectes (NLA), Dimitri Roussel Ensemble Architecture Métropole (Dream), Sou Fujimoto Architects (SFA), Manal Rachdi (Oxo Architectes)

  • Contractor: Société provençale de constructions métalliques (SPCM)

 

Elected by their peers! ​

 

The Archdaily architecture website recently crowned this building in Montpellier the best building of the year in the housing category.    

The architectural audacity to conceive a building with an array of cantilevering balconies and mini pergolas was rewarded with this award.
 
The 193 balconies never overlap, are not perpendicular to the façade and create an additional living space. It almost feels like “living in a tree”.
 
The architects focused on the indoor/outdoor experience in their design, albeit with one priority: every living room had to give out seamlessly on the balcony to eliminate the boundary between indoors and outdoors.
 
The sun-drenched terraces, which face the Mediterranean, have become a living space in their own right.

All the living spaces were designed in line with an eco-responsible approach, focusing on comfort and ecology, while taking the environmental impact into account.

 

Lightness and performance


The balconies, which were supplied to the site disassembled, were assembled in the workshops on the building’s ground floor. Every balcony was lifted into position using an auxiliary hoist with a motorised counterweight assist hoist, to control the platform’s balance.
 
Metal balconies, open balustrades: the finesse with which this project was executed is largely due to steel.
 
The balconies are made of welded profiles with a variable core, that are secured to the façade and that are interconnected by load-bearing beams with a steel tray underneath.
 
The architects had to come up with a solution to meet the following requirements:

  • waterproof so the water from the balconies runs back to the façade

  • the smoothest possible solution

  • with a 60-minute fire rating

  • that also made economic sense

 
After several tests, Joris Ide’s JI Vulcasteel Roof mineral wool core panels were selected.
