Elevator manufacturer ThyssenKrupp has unveiled its latest technological advance, a cable free, multi-car, multi-directional elevator that has the potential to revolutionize the size and shape of future skyscrapers. Run using magnetic technology similar to that used by Maglev trains, with each cabin running its own individual motor, the "MULTI" elevator system opens up the potential for elevator cabins to move horizontally as well as vertically. This in turn offers the potential for multiple cabins to operate in a single system, with cabins going up one shaft and down an adjacent shaft.

BIG has unveiled the design for their addition to the development at Battersea Power Station, a public square that will link the power station itself with the Electric Boulevard development designed by Norman Foster and Frank Gehry. Called Malaysia Square after the Malaysian development consortium behind the plans, the design features cascading steps that link the main public space at the lower level with the entrance to the power station above. The split-level design also provides for two pedestrian bridges and a road bridge that cross above the "urban canyon" of the public square.

"Now is the time for us to create a new interface with the deep sea, the earth’s final frontier," says a brochure from Japanese development company Shimizu Corporation, presenting their outlandish proposal for the Ocean Spiral: a deep sea colony that can supposedly provide for up to 5,000 people in its 500m wide tethered sphere.

The proposal describes the Ocean Spiral as "safer and more comfortable" than existing land-based cities, thanks to the near constant temperature enabled by the ocean, the fact that it will be unaffected by typhoons or earthquakes, and the hope that the city's methods of oxygen generation will enable higher concentrations of oxygen then are found in the Earth's atmosphere.

The 2015 Milan Expo has been keeping architecture fans in the loop with "Belvedere in Città," its continuing series of videos filmed with the help of a drone. Since our update last month, two new videos have been released - and now that the recognizable forms of the pavilions are starting to emerge, the videos include labels for each feature of the expo site. With the help of these new videos it is easy to see the forms of highly-touted pavilions such as Libeskind's Vanke Pavilion, or Nemesi & Partners' smog-eating pavilion for Italy, gradually taking shape around the twin axes of the "cardo" and "decumanus," an ancient Roman planning tool borrowed for the site's masterplan by Jacques Herzog, Mark Rylander, Ricky Burdett, Stefano Boeri, and William McDonough. Read on after the break for the second video, and screenshots of the construction works.

The 2014 Media Architecture Biennale has drawn to a close in Aarhus, Denmark, and with it five projects have been awarded for "outstanding accomplishments in the intersection between architecture and technology." Representing five different categories (Animated Architecture, Spatial Media Art, Money Architecture, Participatory Architecture, and Trends & Prototypes), these five projects are the ones that most represent the Media Architecture Biennale's goal to advance the understanding and capabilities of media architecture.

The winners include a power plant with a shimmering chimney tower, an installation that creates "phantoms" with light, an interactive LED facade, a crowdsourced mapping system for transit in the developing world, and a kinetic "selfie facade." See videos of all five winners after the break.

For its annual Charity Christmas Auction, this year London's Anise Gallery is planning to raise money for Maggie's, the cancer care charity which has commissioned high profile buildings from architects such as Frank Gehry, Zaha Hadid, OMA, Richard Rogers and Snøhetta. The Anise Gallery's auction features works by both artists and architects, including four architects who have contributed Maggie's Centres themselves: Ted Cullinan, Chris Wilkinson of Wilkinson Eyre, and Piers Gough of CZWG, responsible for the Newcastle, Oxford, and Nottingham Centres respectively.

Others featured in the auction include architects Alison Brooks, Peter Murray, Jack Pringle, Christophe Egret, Rab Bennetts Je Ahn and Stuart Piercy, alongside artists including Ben Johnson, Norman Ackroyd and Jeanette Barnes. Until the auction on December 6th, all the works are on display at the Anise Gallery, however online bidding opens on November 26th here - alternatively, check out a selection of the available lots after the break.

In this video from Crane TV, writer, poet, artist, and architect Vito Acconci discusses why his goal is not always to have his projects realized. Beginning his career with an education in creative writing from the University of Iowa, Acconci expresses his longtime desire as an artist for art to become “part of the world,” explaining that this eventually led him to extend his creativity beyond words and artworks. Architecture was the perfect vehicle for this because, unlike art, it is inescapable: "there isn't any place you can be where you aren't in the middle of architecture," he says.

However, unlike many architects, his projects push beyond the constraints of realistic structures, and he estimates that only 10 percent of Acconci Studio’s proposals are realized. To some architects this would seem like a failure, but to Acconci it means that his creative ideas are unprecedented, perhaps paving the way for what architecture could be in the distant future.

After gaining the first in a series of required planning approvals last week, Thomas Heatherwick's highly controversial Garden Bridge proposal has once again come under fire from a variety of opponents, with campaign group Thames Central Open Space (TCOS) dubbing it a "luvvies' folly," and the Guardian's architecture critic Oliver Wainwright saying that it is "not in fact a bridge – in the sense of being a public right of way across the river – but another privately managed tourist attraction, on which £60m of public money is to be lavished."

Much of this new assault is the result of the 46 conditions which came with Lambeth Council's recommendation to grant the bridge planning approval, which as BD Online uncovered, include closing the bridge between 12 and 6am, a ban on cycling, and a restriction of group sizes to 8 people or fewer, unless booked in advance.

The City of Sydney has selected the team of Andrew Burges Architects working with Grimshaw and TCL, as the winners of a competition to design a new park and aquatic centre in Green Square, around 4 kilometres to the South of central Sydney. One of the city's six "Major Development Zones," the park and aquatic centre is part of a larger development in the centre of Green Square, with an adjacent site slated for a new public square and library.

The UK government's Department for Communities and Local Government (DCLG) has concluded that UK architecture should continue to be governed by "light-touch regulation based on protection of title," following the first phase of a review into the future of the Architects Registration Board (ARB). Now, a second phase of the review promises to investigate options to deliver this regulation, determining whether or not it is best achieved by the ARB.

A statement released by the DCLG says that it will now work "with all parts of the profession to identify opportunities to simplify the role of the regulator," with BD Online reporting that the available options including absorbing the role of the ARB into that of the Royal Institute of British Architects (RIBA), or to keep the ARB as an independent body - but with the DCLG warned that "it should not be assumed that an independent regulatory body would necessarily have the same form or role as the existing regulatory body."

If New Yorkers thought that construction during Michael Bloomberg's tenure as Mayor was frantic, then what's coming next might be quite a shock: courtesy of CityRealty, these images show the New York skyline in 2018, when many of the city's current projects will be complete. Produced from building models by TJ Quan and Ondel Hylton as a marketing ploy for Jean Nouvel's 53 West 53rd street which recently (finally) began construction, the images include all of Nouvel's illustrious future neighbors: the "Billionaire's Row" including 111 West 57th Street, 220 Central Park South, 225 West 57th Street (Nordstrom Tower) and One57; new Midtown developments such as 432 Park Avenue, 520 Park Avenue, 425 Park Avenue, One Vanderbilt, 610 Lexington, 15 Penn Plaza, and the Hudson Yards towers; and even the latest financial district towers, 1WTC, 30 Park Place, 125 Greenwich, and 225 Cherry Street.

The Czech Republic-based Arendon Development Company has selected seven British practices and three Czech practices to work together on Oaks Prague, a new €400 million, 220-home "residential and lifestyle development" 20 kilometres South-East of Prague within the commune of Popivičky.

Selected through a competition organized by Malcolm Reading Consultants, the ten practices will join the team of Edward Durell Stone Jr and Associates, who masterplanned the development to include a golf club, hotel and spa at its centre, and John Thompson & Partners, who developed a pattern book and style guide for Oaks Prague.
