“We are offering a new type of work environment, fit for today’s world.” - Dominique Perrault ArchitectThe Pont de Sevres Towers were originally completed in 1975 by architects Badani and Roux-Dorlut, and have since been renamed Citylights following a complete re-structuring by Dominique Perrault Architect. The original buildings are a series of typologically modern high-rise office towers within a barren urban context. The renovation plays a key role in Paris’s recent urban expansion toward Grand Paris, now connected to the city’s public transport system and through a series of pedestrian routes providing a link to the new Trapeze district—a post-industrial revitalization where former factories are being reborn as new office and residential spaces. To physically anchor the towers to the city, the architects planned a range of spaces that open to the community via large plazas, gardens, reception areas, walkways, and communal spaces. “We are offering a new type of work environment, fit for today’s world,” said the architects in a press release. Due to an existing hexagonal floor plate and efficient elevator core layout from the 1970’s, reusing the structure yielded a plan steeped in contemporary logic, efficiency, and reality. Daylight bounces off of nearby tower facades, minimizing the difference between daylight quality in units with northward orientations vs. those with southward orientations. To maximize this effect, the architects integrated lighting and reflective cladding to produce luminous massing volumes. Specifically, 3,400 new facade elements were installed on 366,000 square feet of facade area. Furthermore, the complex contains 81,000 sq. ft. of aluminum cladding and 180,000 square feet of glass. Two-thirds of the building envelope is covered with a flat facade framed in a polished aluminum and spandrel panels of colorless enameled aluminum. The other third of the building envelope is wrapped with a folded facade that creates formal bracelets around the towers. The bracelets are set at varying elevations as a compositional strategy in response to the existing massing of the complex. The bracelets integrate ventilation and LED lighting to reinforce a rhythm on the elevation. Along with an impressive mixed-use 16,100-square-foot base designed by Gaelle Lauriot Prevost, the project also added to the cluster of three towers with a fourth “petal” extension, recycling the same geometry for the original 1975 structures. With a similar exterior shell, the structural system of the tower was optimized to have less core space that affords a larger amount of open space. The renovation of the buildings involved increasing all window openings to be nearly two feet taller. All building equipment is organized into a ceiling plenum which geometrically responsive to the rhythm of the facade glazing. Where glazing occurs on the building envelope, a double-glazed system is integrated with 3” enameled aluminum awning strips, motorized based on weather data from a nearby weather station. Citylights has been awarded two environmental certifications: HQE (“Haute Qualite Environmental), and a “Very Good” level BREEAM (Building Research Establishment Environmental Assessment Methodolody) certification. These standards were achieved after a design process that included three dimensional digital modeling to optimize equipment sizing and locations, the detailing of a “breathable” double skin facade, an automated sun protection system, increased natural light through expanded openings, and a chilled beam induction system to optimize thermal comfort. An energy analysis of the project confirms the buildings consume 50 percent less than a similar sized building, and six times less than a conventional commercial building. The chill beams are able to reduce the heating and cooling load by 30 percent. Additionally, 64 percent of the energy demand in the building is covered by renewable energy which covers a significant portion of the heating and cooling load.
"Housing constitutes 80% of the city, so this 80% has to be exceptional." - Hamonic+MassonHamonic+Masson & Associates has designed the first residential high rise building constructed in Paris since the 1970s. The building, appropriately called “Home,” is a collective assemblage of a staggering 90 apartment typologies, resulting in 200 residential units offering a sense of identity, ownership, and differentiation within a collective building. The alternating stacked massing of the building is clad with prefabricated corrugated sheet panels finished in a two-tiered color scheme of brushed aluminum. The architects said these finishes are employed as a compositional strategy to highlight the transition in the building from repetitive low rise to unique vertical massing elements: “The finishes applied to the cladding highlight the natural beauty of aluminum while the glossy topcoat reflects the sunlight beautifully.” A silver tone continues the contextual lower base units along Avenue de France, while a gold tone is deployed as the massing of the building progresses vertically. Gaëlle Hamonic and Jean-Christophe Masson, cofounders of the eponymous firm, said that while the “postcard image” of Paris is one of uniformly low Haussmannian-designed buildings and historical monuments, there is a need to renew and reinvent the image of the city: “Paris is a city that has constantly reinvented itself and tried to modernize itself.” They say their growing body of work in vertical housing units embraces the traditional urbanism of Paris while offering its occupants a “new vision of their city,” continuing a process of perpetual reinvention. Other materials used on the tower’s balconies include glass with colored interlay, stainless-steel meshing, and coated aluminium for the balustrades, while the terraced roof decks use SOPREMA Exodalle waterproof panels made from exotic Brazilian Massaranduba wood. The aluminum screens were prefabricated off site by local companies Euramax and Alubel, then fitted onto the building by SMAC. Tucked away in the base of the structure are over 300 spring isolators to dampen vibrations from the three level below grade parking garage. A detail unseen, but crucial to the occupant comfort of the units above. Hamonic+Masson told AN that integration of private terraces into the facade setbacks was a key compositional strategy: “It is crucial to create intermediate spaces where residents feel both ‘at home’ and ‘in the open’, having access to the outdoors from the comfort of their own apartment.” The architects say this project is a pedagogical tool - a demonstration that height is an effective urban planning solution for Paris. “Paris is reinventing itself, and this project is the spearhead of the revolution!”
VIB Architecture has constructed a mixed-use program of student housing and a nursery along a narrow site in a busy neighborhood in Paris.In a Parisian neighborhood known for its pedestrian-scale passages and small alleys, VIB Architecture has constructed a mixed-use project skillfully incorporating student housing and a nursery program into a complex of several new construction and renovated properties. The project is located in Belleville, a historically working class neighborhood with strong arts community and a heterogeneous mix of architectural scales arranged along a hilly topography. This latest addition to the neighborhood adds to the mix by combining contextual strategies with a bold contemporary material palette and massing scheme. The project is generally organized around two 8-story buildings that are bisected by an exterior passageway that leads to a courtyard space. Apartments are located along the active street front, protecting a rear sunny courtyard, lined with smaller scale buildings, for use by the nursery. An existing building links the two programs. The most recognizable building is wrapped in a custom-designed perforated aluminum skin, with a massing composed of slightly staggered floor plates with rounded corners. The skin of the building becomes panelized into operable shutters at window locations, allowing for users to control desired levels of shading, privacy and ventilation. The horizontal patterning of the perforations tracks downward into the courtyard, aesthetically integrating the housing and nursery programs, says Franck Vialet, Partner of VIB Architecture. “The perforations give depth and the horizontal stripes vibrate and link the street to the inner gardens.” The building interestingly was originally designed with a wooden rainscreen system, but was dropped early in the design process due to strict fire regulations. Vialet says the resulting aluminum facade became a natural choice due to its material qualities and design flexibility with fabrication processes. “We looked for a skin that could be unique and could be textured or machined into both large scale and smaller pieces. Anodized aluminum was the ideal solution because of its great ability to reflect light and to be perforated easily.” Positioned next to an historic garden, the bronze anodized building acts as a landmark, providing a sense of depth to the urban fabric of Belleville. Immediately adjacent to this building sits a second which is designed to be compatible with existing context, clad in a white plastic coating, the massing of the building is more ubiquitous than the first, while strategically stepping down at the rear facade to gently meet the courtyard. By altering the tectonics of the two buildings, the overall impact of the scale of the project is reduced while reinforcing a central circulation “spine” through the length of the plot, linking two successive courtyards. Vialet says the most successful part of the project is the urbanism it fosters: “its ability to naturally blend into the city and to bring together people from the street, the park, and the courtyards.”
