TVK designs limestone buildings for “first zero-carbon district” in Paris
French architecture practice TVK has completed a neighbourhood in Paris made up of limestone buildings surrounding a garden and designed as a sustainable development that aims to increase biodiversity.
Located on a triangular site in Paris’s 19th arrondissement, the project is “the capital’s first zero-carbon district”, according to TVK.
Named Îlot Fertile, which translates to “fertile island” in French, it contains apartments, a youth hostel, student residences, a hotel, offices, restaurants, shops and sports facilities.
The four buildings that make up the neighbourhood range in height from seven to nine storeys tall, each with ground-floor levels made from low-carbon concrete and designed to achieve large, unobstructed interior spaces.
The upper levels were made from load-bearing limestone sourced mainly from the local Ile-de-France region, aiming to reduce the carbon cost of transportation.
TVK claims the 35,200-square-metre development is the largest load-bearing stone building site since Georges-Eugène Haussmann’s reconstruction of Paris in the mid-19th century.
“Each material is used in the right place and the right quantity,” TVK founders Pierre Alain Trévelo and Antoine Viger Kohler told Dezeen.
“We chose to use mainly limestone from the Paris region – it’s the same one used to build the Haussmann buildings.”
Public spaces, including restaurants and shops, are located on the ground floors of the buildings and open onto the central garden.
Hotel accommodations and apartments are on the upper levels, and a raised outdoor level provides additional garden spaces with an orchard, vegetable patches, insect hotels and nest boxes.
Office spaces are located in a building that sits parallel to a railway line and, aiming to work with the site’s existing topology and move as little earth as possible, TVK designed a sunken sports centre in a large hole on the site to create an interior with high ceilings.
“The biggest challenge of the project was to bring together more than a dozen programmes and turn them into a fully-fledged part of the city,” said Trévelo and Kohler.
“The shape of each building is linked to the very specific geometry of the site shaped by the railway infrastructure,” they continued. “This brings diversity to a building complex of this scale.”
TVK designed Îlot Fertile to have a minimal carbon footprint in its construction and operation. It topped the buildings with photovoltaic panels and green roofs to produce energy while also aiming to increase biodiversity.
“Its proximity to public transport means that Îlot Fertile does not require any car parking, and we used a bioclimatic design to keep energy requirements to a minimum for heating, cooling and lighting,” said Trévelo and Kohler.
“For the small amount of energy that will be consumed, the project plans to compensate for it by producing green energy via bio-solar roofs.”
“Driven by the City of Paris’ ambition for ecological transition, zero-carbon is a long-term objective for the life of the entire operation,” added Trévelo and Kohler.
Elsewhere in Paris, Christ & Gantenbein completed a 124-metre-long steel-clad housing block, and RSHP unveiled its design for a “post-carbon” neighbourhood that will be located in the La Défense business district.

New York is a city known for housing scarcity, and a place that’s defined by reinvention. For Timber House, MESH Architectures was inspired by natural finishes and “botanical architecture.” The idea was not only to foster well-being, but create a new model for timber construction in the city. The project is the first mass-timber condominium in New York, and the structure was built with glue-laminated timber columns, beams, and floor plates. The six-story, multifamily project is comprised of fourteen homes.
MVRDV has earned a reputation for reinvention and creating new building forms. That same approach extends to housing, where the team designed Valley with a more “green and human” touch. Built for developer Edge, the project is located in Amsterdam Zuidas. Rising to three distinct towers, the façades shift across the complex. The outer edges are mirrored glass, while the inner façades are clad with stone and swaths of greenery.
Few locations are more prominent for multifamily housing in St. Louis than Forest Park. Designed by Studio Gang, One Hundred is a residential tower overlooking the park and the studio’s first project in the city. The tower includes a mix of housing, retail and amenities on four-story stacked tiers. The apartments were designed for views of Forest Park and east to the Gateway Arch.
The Cirqua project by BKK gained widespread recognition for creating beautiful, inventive multifamily architecture. The project includes 38 unique unit types out of the 42 total apartments made with spacious balconies and an integrated approach to landscaping. Combining two properties into a single block, the project was formed with careful attention paid to scale and the surrounding context. Cirqua not only showcases a smart, nuanced approach to multifamily housing, but also how to design for accessibility and passive performance.
Caterpillar approaches density through a novel construction and design in Core City, Detroit. It utilizes a Quonset Hut structure that holds eight units, all entirely prefabricated. The result is an 8,000 square foot (745 square meter) residential project that prioritizes indoor and outdoor space. Prince Concepts created the project with tall ceilings that rise to 23 feet (7 meters); the units were designed to capture morning light in the bedrooms and evening sunsets in the living room.
CPDA Architects designed this garden house project as a multifamily development in Mexico City. Located in the Escandón neighborhood, the project includes fourteen residential units. At its heart, a central courtyard is the connective element that defines the housing project, opening up access to natural light and cross ventilation. Ten townhouse units are set up the four ground-floor units below, all of which share a similar material relationship.
Few cities in the world are grappling with homelessness and a severe lack of housing affordability like Los Angeles. Brooks+Scarpa has built a practice addressing issues in the city and across the nation. For this multifamily residential, The SIX was designed as a 52-unit affordable housing project that “provides a home, support services and rehabilitation for previously homeless and/or disabled veterans.”
Over the last two decades, development in China has been defined by a dizzying pace and new architecture produce in-mass. For Jinshan 9, this force behind new buildings was directed into a multifamily living community. Located in China’s Shekou mixed-use district, the project looks out west to wild, forested mountains and east to Shenzhen Bay Bridge. With a range of both low-rise and high-rise structures, the development was made for diverse lifestyles and populations.
