Inaba Williams creates mirrored stucco-clad residences in California

US studio Inaba Williams Architects has created two mirrored houses with courtyards in Santa Monica, California that are clad in white stucco and have net-zero energy use, according to the studio.

Completed in 2023, the twin five-bedroom houses measure 3,900 square feet (362 square metres) each and are divided by a privacy wall and rectangular lap pools.

Brooklyn-based practice Inaba Williams Architects followed strategies laid out in Title 24 – California’s Building Energy Efficiency Standards – to create net-zero emissions houses “better suited to our future climate conditions”.

“Having far fewer windows, the buildings reduce heat gain and energy use, while allowing residents to enjoy indoor outdoor living,” the studio told Dezeen. “With less need for air conditioning and generous access to landscaped areas, they offer a more natural, less tempered experience with the environment.”

Set on 40-foot (12-metre) wide lots, the linear homes measure only 20 feet (6 metres) at their widest, leaving plenty of space for outdoor areas on either side of the house for residents to enjoy.

Residents enter from a small courtyard on the outside street-edge corner of the lot into a rounded entryway that passes directly into the main exterior courtyard.

At the northern end of the site lies a small two-storey volume that holds a media room and a private suite.

Moving deeper into the house, the living, dining and kitchen areas are collected into an open-plan space with windows and sliding doors that look onto the outdoor areas – including a dining patio – which bring daylight in from three sides.

A bedroom suite, garage, and a secluded zen garden hold the southern edge of the site.

“The courtyards are the focal point of the side-by-side homes,” the team said. “Following the Energy Standards’ option to use glass on just 20 per cent of the exterior surface area, the limited amount of glazing is concentrated around these central outdoor areas. “

Positioned to maximize daylight, the courtyards and auxiliary areas capitalise on the coastal location’s mild climate and can be used every day.

“Similarly, taking into account the solar path, the building massings let ample sunshine into the courtyards over the day and year,” the team said.

The all-white houses have simple materials to accentuate their forms, with stucco on the exterior. White walls and terrazzo and hardwood floors feature on the interiors. The coving along the ceiling is made of glass fibre-reinforced concrete from a local vendor.

Outside, brick pavers are set in a herringbone pattern that provides a soft geometrical detail to the smooth forms and green planted beds add color and texture.

Combined with the low glass-to-surface area building envelope, root-mounted solar panels help the homes meet California’s Zero Net Energy criteria, however hitting performance metrics wasn’t the team’s driving force.

“We think the more approaches there are to creating a sustainable future the better, and the Standards could have a cumulative climate benefit,” the studio said. “Just as the New York 1916 Zoning Resolution shaped the highrise tower type, California’s Energy Code can help shape the house type by being a framework for experimenting with its form and layout.”

“Its requirements can be guidelines to think inventively about climate-oriented design – to evolve our collective thinking about the type in a positive way.”

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.
