In China’s capital city, Zaha Hadid Architects has completed the Leeza SOHO tower, a 45-story skyscraper that boasts the world’s largest atrium at 194.15 meters in height. Designed to anchor the new Fengtai business district in southwest Beijing, the futuristic tower is wrapped in a double-insulated unitized glass curtain wall system that curves around its twisting, sculptural form. In addition to double glazing, the Leeza SOHO incorporates water collection, low-flow fixtures, a green roof , photovoltaic panels and other sustainable measures to meet LEED Gold standards. Set atop an underground subway service tunnel, Leeza SOHO was strategically sited next to the business district’s rail station at the intersection of five new lines that are currently under construction. The tunnel that bisects the tower splits the building into two halves; the resulting void in between has been turned into an atrium that acts as a new public square.

Indoor comfort is further achieved with the low-E, double-insulated glazing that ensures stable temperatures. To meet LEED Gold standards, Leeza SOHO features an advanced 3D BIM energy management system to monitor real-time environmental control and energy efficiency. Energy-saving measures include heat recovery from exhaust air; high-efficiency equipment such as pumps, fans and lighting; low-flow water fixtures and gray water flushing. Low-VOC materials were selected to minimize interior pollutants. Occupants and visitors can also enjoy plenty of bicycle parking, with 2,680 spaces available, as well as lockers and shower facilities. Underground, there are also dedicated charging spaces for electric and hybrid cars. + Zaha Hadid Architects Images by Hufton+Crow / Zaha Hadid Architects

Comments Off on BIGs LEED Gold-seeking school in Arlington features a cascade of green terraces

After five years in the making, BIG has completed The Heights, a new public school building in Arlington, Virginia that not only offers a unique and energy-efficient take on school architecture, but also helps maximize density and open space. Located along the Rosslyn-Ballston corridor, The Heights combines two existing secondary schools into a new 180,000-square-foot building that opens like a fan with a cascade of green-roofed terraces to provide an indoor-outdoor learning landscape. An emphasis on natural daylighting, green space, material reuse and energy efficiency has put the building on track to achieve LEED Gold certification . Completed on a $100 million budget, the dynamic new school building houses two programs: the H-B Woodlawn Program that offers visual and performing arts-focused curricula for grades 6 through 12, and the Eunice Kennedy Shriver Program that serves students aged 11 to 22 with special needs. The school can accommodate an expected enrollment of up to 775 students. Related: Rammed earth Kopila Valley School is the “greenest school in Nepal” To make the most of a compact urban site bounded by roads on three sides, BIG organized the school as a stack of five rectangular floorplates rotated around a fixed pivot point to create a series of outdoor green-roofed terraces connected with a rotating central staircase. The spacious first terrace can be used for special events while the upper terraces are more suitable as classroom and study areas. The classroom “bars” have also informed the interior layout, which is anchored by a central vertical core containing the elevators, stairs and bathrooms as well as a triple-height lobby with stepped seating on the ground floor. For easy accessibility and to encourage public interaction throughout the school, the lobby is directly adjacent to many of the school’s common spaces, such as the 400-seat auditorium , main gymnasium, library, reception and cafeteria. Intuitive wayfinding is also extended to the classroom spaces in that each classroom “bar” is defined by its own color used to paint the walls and lockers. In contrast to its colorful interior, The Heights’ exterior is clad in white glazed brick to unify its fanned-out massing and to respect the surroundings, including the historic architecture of Old Town Alexandria. Select materials from the former Wilson School, which The Heights was built to replace, have been salvaged and reused in the new build. + BIG Photography by Laurian Ghinitoiu via BIG

A modern timber house in Indonesia celebrates mummified wood

Comments Off on A modern timber house in Indonesia celebrates mummified wood

When Bandung-based architectural studio Aaksen Responsible Aarchitecture was asked to renovate an old house in the West Java neighborhood of Kiaracondong in Indonesia, they made a surprising discovery. During the demolition process, the architects found that the wooden roof truss structure was in very good condition, despite its age, thanks to a culturally significant type of timber, a kind of Albizzia wood that’s been mummified to improve strength and durability. Described by the architects as a “local treasure,” the timber was not only preserved in the roof truss, but also becomes a defining element in the contemporary home, aptly named the Albizzia House. Completed in 2019, the Albizzia House spans an area of approximately 2,000 square feet across two floors. The existing timber house was partly demolished to allow for a reorganization of the layout and a structural expansion. Organized around a light-filled atrium housing the primarily living spaces, the home now includes three bedrooms, garden and terrace spaces, a reading room and a ground-floor prayer room. Natural light and ventilation is optimized in the renovated dwelling. One of the key changes to the house was the addition of timber cladding as a secondary skin to mitigate unwanted solar heat gain and privacy concerns. The vertical timber slats—and interior wooden furnishings—are a visual continuation of the Albizzia wood used as accents in the ceiling and reading room. The preserved wood in the existing building’s roof truss is also highlighted with the expansion of the truss into the new structure. Related: Green-roofed Hanging Villa is embedded into a lush jungle landscape Although Albizzia, a fast-growing and economical timber, is typically considered low-grade due to its weak and brittle qualities, local farmers in Ciamis, West Java, discovered long ago a method to improve upon the strength of the wood. In this “long-established technology,” the locally procured wood is buried under the paddy fields after the harvest season and the timber is then “mummified” in the compaction process, which, according to the architects, greatly increases the wood grade. + Aaksen Responsible Aarchitecture Via ArchDaily Images by KIE

Comments Off on Modern rammed earth home embraces the desert landscape

Named after the way light bounces off of its angled walls and ceilings, Dancing Light is an award-winning dwelling nestled in the desert town of Paradise Valley, Arizona. Local architecture practice Kendle Design Collaborative crafted the custom residence, giving it a sense of drama with pointy pavilion-like rooflines, yet grounded the design through indigenous materials and a desert-inspired color palette. Full-height walls of glass also embrace the landscape and the home is also set up to optimize indoor-outdoor living. Spread out across 6,200 square feet on a single story, the Dancing Light Home organizes the master suite, open-plan living spaces, and a four-car garage as seemingly separate structures around a central atrium—landscaped with rocks, succulents, and an ironwood tree—and linked with glass-walled corridors to allow daylight and cross-breezes to penetrate deep into the house. Key to the design is the dramatic floating roof canopy that lifts upwards at the outer edges of the home to draw the eye up and out towards panoramic mountain views. The angled, tectonic-like surfaces were inspired by the local geology and monsoon cloud formations; the “fissures” conceal the lighting and mechanical systems. “ Natural light brings this home to life, seeping in through carefully articulated crevices or reflecting off the strategically located pool, constantly transforming the mood of this home,” explains Kendle Design Collaborative in a project statement. “At times water-reflected light dances across the fractured planes of earth and wood while at other times it provides a Zen-like sense of calm.” Related: Rammed-Earth Quartz Mountain Residence Captures Beauty of Arizona Desert ` The cast-in-situ concrete walls and the rammed earth walls tie the building into the desert landscape and create a rustic feel. The materials also have the added benefit of absorbing heat during the day and dissipating it at night to reduce reliance on mechanical heating and cooling systems. + Kendle Design Collaborative Images by Alexander Vertikoff

Magical rainbow swamp goes viral

Comments Off on Magical rainbow swamp goes viral

Earlier this week, Brent Rossen posted a photo on Reddit that his girlfriend took of a rainbow swamp, and within 24 hours the photo received more than 120,000 upvotes. The couple was enjoying a walk at First Landing State Park in Virginia when they came upon the unusual phenomenon. “Me and my girlfriend were walking in the woods the other week and saw a rainbow pool for the first time,” Rossen wrote in his post. Related: Magical artworks place lamps, books and chairs in the middle of nature So how does this happen? Jeff Ripple, a former Florida swamp walk leader, told the BBC that the rainbow effect occurs because of the natural oils released by decaying vegetation. The decomposing leaves in the water release tannic acid and a thin film forms on top of pooled water in swamps and marshes. When the sunlight hits it at a certain angle, you can see the gorgeous colors. However, if you look at the water in a shadow, it appears to be normal swamp water. But, on a sunny day, you can see the rainbow when you look at it from an angle. The water also needs to be still for a long period of time for the rainbows to appear. Ripple says that any movement from sheet flow, wind disturbances, or current will “destroy the fragile rainbow film.” This phenomenon reportedly happens at various swamps and marshes along the Eastern seaboard. Retired engineer Michael Hussey posted a pic on Facebook of a rainbow pool in Tallahassee, Florida. Swamp walk leader Sandra Friend has also blogged about her experience with rainbow swamps, and Annie from Not Just Abroad has also posted about a rainbow swamp in Caw Caw County Park in Charleston, South Carolina. Hussey says that he sees this happen every three to four years, and it is “beautiful to see.” Thomas Thornton, facility manager at Caw Caw swamp, says that it must be the result of some kind of perfect storm, and it seems like you have to be lucky to see it in person.

Comments Off on Architects recycle shipping containers into a breezy Dhaka home

In Dhaka, Bangladesh , local architecture firm River & Rain transformed four shipping containers into a light-filled, three-story house spanning 134 square meters. Completed in 2017, the cargotecture dwelling doesn’t hide its shipping container roots yet manages to exude a welcoming and livable atmosphere through strategically cut openings, terraces that emphasize indoor-outdoor living and greenery that grows up, around and through the building. Recycled materials were also used throughout the home, which is named Escape Den after its tranquil setting on the outskirts of the city. Spread out across three floors, the Escape Den organizes the kitchen and dining spaces on an elevated ground floor and places the living room and bedroom areas on the upper levels. Accessed via a side gate off of a dirt road, the property features an entry sequence that begins with a short flight of stairs from the parking pad to a sheltered deck. The deck consists of the dining area and other seating options oriented to face views of the lawn, which takes up approximately two-thirds of the site. The covered deck also connects to a shipping container converted to house a small media room, kitchen and bathroom. The caretaker’s room is located in the back. A flight of stairs traverses the central atrium space — anchored by an almond tree and a veil of green vines that hang from the ceiling — and connects to a glass-enclosed living room. Another flight of stairs leads up to the third floor, where a third shipping container, housing the two bedrooms, is set perpendicular to the bulk of the building in a dramatic cantilever and is topped with a green roof . One of the bedrooms also connects to an outdoor terrace . The green-roofed shipping container can be reached via a spiral staircase. Related: German company converts old shipping containers into gorgeous living spaces “The hefty look of those containers has become dramatically airier with some skillful ensemble of architectural details,” the architects explained. “The floated platforms of the house, intertwining stairs and diverse direction of container placement have made the project more visually eye-catching.” + River & Rain Photography by Maruf Raihan , Hasan Saifuddin Chandan  and Snahasis Saha via River & Rain

Comments Off on Weathered steel trees wrap around a solar-powered school building

Delft-based architectural office cepezed recently completed a solar-powered branch for Graafschap College in Doetinchem that — unlike most school buildings in the Netherlands — eschews natural gas in favor of a power supply that’s 100 percent electric. Built for the students of the Sports & Exercise and Safety & Craftsmanship departments, the new school building prioritizes a healthy indoor learning environment that maximizes access to natural daylight and views of the outdoors. In homage of the many oak trees that grow around the building, the architects partially wrapped the structure in tree-shaped weathered steel cladding that serves as a double skin for solar shading. Built to house approximately 700 students, the new Graafschap College branch at Sportpark Zuid features at its heart a large, light-filled atrium named The Midfield in reference to sports and teamwork. The Midfield is organized into a series of cascading terraces with large landing areas that serve as informal meeting spaces. The glass atrium roof floods The Midfield with natural light and is combined with sensor-enabled LED lighting to reduce reliance on artificial lighting. “In order to be able to look over the car park from the ground floor, and to give the building the appearance of a pavilion in green surroundings, the school has been elevated by a half-story and placed on a basement,” the architecture firm noted. “Beside the car park, the height difference is bridged by an elongated, landscaped staircase, which also incorporates a ramp.” Related: Green-roofed Copenhagen sports center is open to the public 24/7 For the facade, the architects installed alternating strips of glass and black aluminum panels to create a sleek and modern appearance. A second skin of perforated Corten steel cut into the shapes of oak trees is laid over the east, west and south facades of the building and helps deflect unwanted solar gain without preventing daylight from entering the building. cepezedinterieur handled the interior design, which also follows a contemporary aesthetic but with brighter colors and patterns that allude to sports and movement. In addition to solar panels, the school also uses solar boilers for water heating. + cepezed Photography by Lucas van der Wee via cepezed

Comments Off on This breezy, green-roofed home in Singapore embraces nature from all angles

Whereas many modern buildings in Singapore rebel against the country’s tropical climate with air-conditioned, hermetic spaces, international architecture firm Guz Architects decided instead to embrace the natural environment in its design of the Willow House. The single-family home takes on a breezy, pavilion-like appearance with open and well-ventilated spaces that tap into passive design principles and crosswinds for cooling. Draped in climbing plants and organized around ponds and gardens, the home feels like an extension of its lush surroundings. Spanning nearly 900 square meters, the Willow House was completed in 2012 for a young couple with three small children. “The house aimed to create dynamic spaces that encourage play and interaction,” the architects said. Surrounded by tall trees, the home is located in a private oasis of calm that looks a world apart from the dense urban environment  for which Singapore is famous. Oriented to optimize access to cooling breezes, the two-story residence is laid out in a L-shaped plan that wraps around a central courtyard with a pond. A single-story open veranda with an accessible rooftop garden anchors one side of the water courtyard and houses the primary living spaces. The other communal areas — such as the kitchen and dining room — as well as the concealed service areas are located on the ground floor, while the private areas are placed above on the first floor. The master bedroom and children’s bedrooms are placed on opposite sides of the first floor. Related: Lush green roof camouflages the Chameleon Villa into the Indonesian tropics A covered outdoor walkway on the first floor overlooks views of the roof garden and central courtyard , which comprises a large fishpond and a small island with trees. “The movement of water and fish brings life into the courtyard and draws the eye away from the building,” the architects said. In the area between the veranda and kitchen, the fishpond transitions into a shallow freshwater reflecting pond and finally transforms into a 3-meter-deep swimming pool that mirrors the home’s L-shaped layout. + Guz Architects Via ArchDaily Images by Patrick Bingham-Hall

Comments Off on Historic Luxembourg building is metamorphosed into an eco-friendly powerhouse

Paris-based Vincent Callebaut Architectures has placed first in POST Luxembourg’s international design competition with its chrysalis-inspired vision for transforming the telecommunication company’s historic headquarters building into a carbon-neutral city landmark. Dubbed the Metamorphosis of the Hotel des Postes, the winning design includes nearly 120,000 square feet of mixed-use space comprising housing, co-working, retail, a brewery, restaurant and a permaculture rooftop garden. Although the design calls for a significant revamp of the structure’s energy systems, the architects will also take care to preserve the building’s historic architectural elements that date back to the turn of the 20th century. Designed by the government architect Sosthène Weis in the early 1900s, the historic building is mainly built of stone and reinforced concrete but has also been remodeled over the years with several extensions. Vincent Callebaut Architectures will begin its “metamorphosis” of the property by removing three of the extensions and then carefully inserting new changes, which include transforming the interior courtyard into a covered atrium. Central to the redesign is the addition of a chrysalis-inspired, multi-story volume in an oblong shape as well as a photovoltaic cell-studded glass “solar dome.” “[Our goal is to] reveal the intrinsic heritage qualities of the building and highlight them with contemporary architecture that assumes its era,” the architects explained. “Between history and modernity, between heritage and innovation, this metamorphosis presents a project reinforcing the patrimonial identity of the place by transforming the historic building into a showcase of contemporary, ecological architecture. Low-Tech and high-tech are therefore in tune to serve this exceptional project.” Related: Five bridges topped with urban farms could revitalize war-torn Mosul Designed to meet carbon-neutral status, the project aims to consume less than 30 kWh of energy per square meter annually and meet near net-zero energy targets. The building will not only be powered with renewable energies such as solar, wind and biomass, but it will also be renovated to follow passive design principles and updated with an airtight building envelope, double-glazed windows and highly efficient insulation. Metamorphosis of the Hotel des Postes is currently seeking approval from the local government. + Vincent Callebaut Architectures Images via Vincent Callebaut Architectures

Comments Off on Historic warehouses transformed into a swanky boutique hotel in New Orleans

New York City-based architecture and interior design firm Stonehill Taylor tapped into New Orleans’ storied past for its design of The Eliza Jane , a new boutique hotel a few blocks west from the city’s iconic French Quarter. The unique hotel was created from seven centuries-old warehouses that were combined and renovated to form a variety of elegantly dressed spaces including 196 guest rooms with 50 suites, a fitness center, garden courtyard, lounge, restaurant, and lobby. Created as part of The Unbound Collection by Hyatt, the Eliza Jane hotel was named after Eliza Jane Nicholson, the first woman publisher of a major metropolitan newspaper in the United States. In the late 1800s, Eliza Jane had worked as the publisher of ‘The Daily Picayune,’ which was one of the original warehouse occupants. Moreover, Stonehill Taylor wove references to ‘The Daily Picayune’ and the buildings’ other original occupants—like the Gulf Baking Soda company and the Peychaud Bitters Factory—throughout the adaptive reuse design. The ‘Press Room’ lounge on the ground floor, for instance, is decorated with typewriters and other antiques referencing a 19th-century newsroom. “The intent was to create a quintessentially New Orleans setting, a sophisticated blend of old and new, that pays homage to the building’s past,” says Stonehill Taylor in a statement. “The hotel is built within seven historic warehouses that stand distinct on the outside but have been internally conjoined to create the luxury accommodations with a 2,000-square-foot open-air interior courtyard .” Related: Abandoned NYC warehouse is reinvented as LEED Gold-certified apartments The arrival sequence is anchored by a 60-foot-tall light-filled atrium surrounded by lush greenery and the original exposed brick and slate-colored plaster walls. Repurposed materials can also be found throughout the interior, while new custom wall coverings reference the different historic uses in each building. The opulent material palette is combined with vibrant patterns and rich colors to create a setting that feels luxurious and uniquely New Orleans. + Stonehill Taylor Images via The Eliza Jane
