Urban Architecture (UA Studio 7) and Aedas' winning proposal for the Hongqiao Central Business District has broke ground at Shanghai’s domestic Hongqiao Airport, mainland China's fourth busiest airport. The 18.4 hectare office and retail center, masterplanned by UA, has been divided into two parts: UA Studio 7 will design the office district, “a flower with eight leaves,” while Aedas designs the shopping, hotel, and conference center along a "bow curve" of pedestrian flow.

According to UA, the winning scheme's success was "due to a highly energy-efficient architecture proposal combined with an urban plan that allows for pedestrian-friendly spaces."

Arctic Harvester was the first prize winning entry in the “Innovation and Architecture for the Sea” category of the Jacques Rougerie Foundation International Architecture Competition, 2013. It proposes an itinerant soil-less agricultural infrastructure designed to drift the circulating ocean currents between Greenland and Canada, exploiting the nutrient-rich fresh water released by melting icebergs as the basis for a large-scale hydroponic-farming system. The floating facility is equipped to house a community of 800 people, inspired in its compact urban form by vertically oriented, bayside Greenlandic villages and their social, cultural and economic relationship to the sea.

Amsterdam-based NL Architects has been shortlisted, alongside three other prestigious teams, to design a new “ArtA” museum and film house for the city of Arnhem. Uniting four main programs - a cinema, art square, museum and park - the “wedge-shaped” structure is designed as an “urban moraine” that cascades towards the city and invites residents to experience the Rhine from an elevated parkway. This formation grants pedestrians two options for museum access: up the Baroque-inspired rooftop park or through the ground level “Art Square” which serves as a “public intermediary” between the building and city, as well as the museum and film theatre.

Kengo Kuma, one of four renowned architects competing to design the highly anticipated ArtA cultural center in Arnhem, has shared details about their shortlisted proposal. Enveloped in an “elegant filigree screen” of contextually prevalent red clay roof tiles, the “multileveled Arts Square” is designed to serve as “the living room of the city.” Its main programs, the Focus Film Theatre and Museum Arnhem, are united by a series of green terraces whose main purpose is to reconnect the inner city to its “unexploited resource,” the Rhine River.

New York-based SO-IL, together with Architectuurstudio HH (AHH) and ABT, has unveiled details of their shortlisted design for Arnhem’s highly-anticipated ArtA cultural center. One of four shortlisted proposals, SO-IL’s “energy-neutral” building aims to serve as a transformative link that connects the inner city to the Rhine River. “Generous and flexible programmatic volumes,” which were shaped by the surrounding context, are designed “support the production and experience of culture, as well as create a place for reflection and wonder – a transportive experience.”

As we announced yesterday, four impressive teams have unveiled their shortlisted proposals to design a new house for an existing art museum and film theater on a waterfront site in Arnhem. Competing to design the “ArtA” cultural center includes BIG, who teamed up with Amsterdam-based Allard Architecture to propose a scheme that would merge the two facilities by constructing “a simple building volume of two poles: The Film Theater facing the city and the Art Museum facing the river.”

Washington D.C. Mayor Vincent Gray has named Mecanoo architecten and Martinez + Johnson Architecture winners of a competition to reinvent Mies van der Rohe’s Martin Luther King Jr. Memorial Library - the only library and D.C. building ever designed by the legendary architect. The Netherlands- and D.C.-based team aims to resurrect the neglected building by improving "Mies in a contemporary Miesian way." This includes opening up the boxy interiors to enhance flow and increase natural light and, most dramatically, sculpting two rooftop terraces by topping the historic landmark structure with a four-story, mixed-use addition.

Smiljan Radic has been announced as the winner of the competition to design a landmark on San Cristobal Hill, in the heart of Santiago, Chile, that consolidates the hill's numerous antennas into a single infrastructure.

According to the Contest Director, Luis Eduardo L. Bresciani, the purpose of this competition was to generate an innovative structure of iconic character, an architectural work of outstanding quality that would differ from other towers in other cities and give an identity not just to the hill, but to the city of Santiago. The jury also took into account the landscape of the site, particularly the care with which the park would be treated, as well as the tower's relationship with the statue of the Virgin and the hilltop in general. Finally, the functionality of the infrastructure, which should act as both a telecommunications tower as well as a public space with panoramic views, was considered. See the six shortlisted proposals, after the break.

A design team led by Carlos Marín and José Muñoz-Villers has claimed first prize in Mexico City’s "La Merced" competition for their masterplan proposal to re-conceive the popular marketplace, Plaza Central La Merced. The team’s design, which beat out about 100 other entries, proposed the realization of a new public square to centralize pedestrian activity and to anchor strategies for urban revitalization, such as the reclamation of local heritage sites, the careful manipulation of natural elements, and the installation of urban furniture as a means for placemaking.

UNK Project Architects' entry for the Ministry of Culture of the Russian Federation's National Centre for Contemporary Arts (NCCA) competition centres around the interplay between art and architecture: "It’s what touches our soul and motivates us to pursue radical new ideas." Reaching the second stage of the international competition, which has been won by Heneghan Peng Architects, UNK Project Architect's proposal offers an intriguing, "almost airtight" space veiled by a monolithic façade facing landscaped urban space in the centre of Russia's capital.

J. Mayer H. has been crowned as winner of an invited competition to design a 19-story medical services and residential high-rise in the center of the Rhine-Ruhr metropolitan region. The “sculptural” tower, which is defined by the horizontal “cloud-shaped” aluminum strips that cloak its facade, is designed to “provide a natural atmosphere” enhanced by planted terraces and balconies overlooking the adjacent landscape of the Rheinaue and views of Duesseldorf.

Farrells has been announced as winner of an international competition to masterplan two prominent commercial zones in Shenzhen’s Qianhai financial district. Adjacent to the district’s Qianhaiwan metro station, the two districts are expected to boost cross-border trade between Shenzhen and Hong Kong.

The Emerging New York Architects (ENYA) committee of the AIA New York Chapter has announced the winners of its 2014 biennial design ideas competition, QueensWay Connection: Elevating the Public Realm. In an effort to imagine the ways in which The Trust for Public Land and Friends of the Queensway could transform an abandoned railway in Central Queens into a vibrant urban greenway, entrants were challenged to design a vertical gateway for the elevated viaduct portion of a 3.5 mile stretch along the rail.

Of the 120 submitted proposals from 28 countries, the jury selected the following winners to represent the diverse array of ideas generated:

Young Projects will be spending the week playing “Match-Maker” in New York City, as the Brooklyn-based studio has debuted their interactive Valentine’s Day installation in the heart of Times Square. Made in collaboration with fabricator Kammetal, as part of Times Square Alliance’s sixth annual heart design competition, the interactive heart-shaped sculpture is designed to cosmically connect people based on their zodiac signs by arranging curious passerby's at twelve points surrounding the installation.

As Young Projects describes, “Peering through colorful, interwoven periscopes provides glimpses of each viewer's four most ideal astrological mates, offering potentially novel connections between lonely souls or settled lovers.”

Toronto-based RAW Design has been crowned winner of the annual Warming Huts competition, which is intended to “push the envelop of design, craft and art” by encouraging architects to design innovative warming shelters along the frozen Red River Mutual Trail in Winnipeg, Canada.

Moving away from the traditional notion of an enclosed shelter, the firm’s winning proposal “Nuzzles” engages skaters with a playful arrangement of “insulated appendages” (a.k.a. pool noodles) supported by a geodesic lattice structure that is illuminated and heated from within. Users are encouraged to “nestle into the structure” and manipulate its fur-like exterior into informal resting areas.
