Studio Gang Unveils Alternate Design for Tour Montparnasse in Paris

Studio gang has unveiled its second place-winning design to transform the montparnasse tower, the sole skyscraper within the periphery of paris, into a shimmering landmark with a faceted façade. while a design by nouvelle AOM was selected as the winner of the competition, newly unveiled renderings reveal the details behind studio gang’s alternate proposal.

as one of two finalists to advance to the final round of a multi-stage international competition in june 2016, studio gang sought ‘to create a powerful, dynamic, and bold new identity for the tour montparnasse, while fully addressing all modern challenges regarding user accessibility, comfort, and energy performance.’ the sculpted tower proposal features a rounded floor plan shape that gives the building flexibility to accommodate new and varied uses in the future. ‘as europe’s densest city, one of paris’ biggest challenges is finding new sites for working and living space within the city limits’, explain the architects.

the building seeks to integrate technological efficiency with user comfort and experience. bay windows create more than 1000 ‘belvederes’, providing great views to tenants. the self-shading technology of the bay windows also furthers the sustainable strategy of the building. the design’s synthesis of sustainable systems reduces the building’s current primary energy consumption by 89%, achieving an exemplary level of environmental performance. inside, the facets of the new façade form bay windows that produce generous, flexible work spaces and gathering spaces that are filled with natural daylight.

the tower is crowned by a glass observatory supported by a steel corolla structure. open to the public, the pavilion offers 360-degree views of the city and houses a garden and event space to host a variety of cultural events. all seven of the competition semi-finalists’ designs — including a proposal from MAD architects — are on display at the pavilion de l’arsenal in paris through october 22, 2017.
