Bogen Tower, a lighthouse facing the river


Housing  /  Completed

The 16-storey Bogen Tower stands on the Rhine, just like a lighthouse facing the river. With its architectural bias made of vertical strata, with its balconies which railings are made of glass, the high standing building attracts the eye with its sculptural style. With the building’s lines and heights, the inhabited rooms benefit from views over the Rhine, the town and the territory. Les Jetées district has been designed to allow all residents to enjoy the qualities of this exceptional site. All the accommodations benefit from a private outdoor space, largely vegetated and designed as a loggia to preserve the privacy of the residents. Thus, the offset of the tower blades offer an unobstructed view to every dwelling.

The project opens the town of Huningue up to the Rhine, by extending the city center towards the riverbanks, thus creating a real river district. It combines a strong architectural ambition and an exceptional environment at the crossroads of France, Germany and Switzerland. Architects were inspired by the town, the river and Europe to draw a building which fits into the natural landscape of the place. The architectural design of the project was guided by 3 criteria: opening the town up to the river by creating a new relationship with water, integrating the town in the Basel conurbation through an iconic project, and offering an exceptional new place to live for residents. This omnipresence of nature makes the new district a refuge for biodiversity, which will thus be preserved.

The tower conception is turned to an optimal landscape integration and preserve the biodiversity of the banks of the Rhine.

The main desire was to provide the tower with large openings and XXL outdoor spaces with the presence of large planters to bring greenery, because the bias of the tower is the comfort of use above all.

The Bogen tower is part of a new district "les Jetées" whose bias is focused on Europe of the quarter of an hour. Considered by all researchers and urban planners to be the key to the city of tomorrow, and the first response to global warming according to the IPCC, the quarter-hour city, that of hyper-proximity, makes it possible to respond to our social and environmental challenges.

A word from the architect Jean-Baptiste Pietri: “This tower stands like an arrow, like a flag, to signify a threshold marking an entrance, that of a town, that of a country. » The architectural bias of the project lies in its vertical strata design, and the facade materials contribute to this ambition. The North and South facades are made of white metal cladding. The inside of the slats is made of a white coating and the slices of cladding, also white, are positioned vertically. The West and East facades are dark gray. The glass railings of the balconies play with transparency and show the different views over Les Jetées. The partitions of the apartments are marked by planters with a maximum depth of 60 cm to bring greenery to the tower, reminiscent of the natural environment of the neighborhood by the river. The structure of the intermediate floors has been designed in a way to form a veritable green grid, rising at a height of 15 meters above the ground, and extending over the entire horizon line. The exterior joinery of the project is in lacquered aluminum with thermal break for efficient insulation. The black color was chosen to create a contrast with the white metal cladding and the parapets are raised to ensure the role of the railings for the North and South facade, they are protected by white lacquered aluminum copings.

This mixed real estate project led by Constructa combines a strong architectural ambition and an exceptional environment at the crossroads of France, Germany and Switzerland. At the entrance of the Trois Pays footbridge, Les Jetées provides a modern impetus to the city, which was formerly fortified by Vauban. This project is designed by four French architectural offices: PietriArchitectes, Triptyque Architecture, Nicolas Laisné and DREAM. Each building affirms its uniqueness.

Jean-Baptiste Pietri, originally from Marseille settled in Paris 30 years ago where he founded his architecture studio in 2001. His team, which has twenty collaborators, is based in the 11th district of Paris.
The vision of PietriArchitectes was inspired by the Mediterranean region, and its projects inherited from the typical architecture of the coast, mixed with Parisian inspirations and the Haussmanian harmony of the city. Architects propose a solar architecture, with curved shapes and white limestone tones, generating a generous architecture respectful of its environment.
PietriArchitectes builds all around France, thus confirming the plurality of its architectural vocabulary which adapts to the building context, while deploying a style of its own. Its projects cover a wide diversity of programs, both public and private, ranging from single-family homes to office towers, including a luxury hotel on the waterfront and and a clear interest in interior design.
