Last night was the opening of the new Armani megastore on New York’s Fifth Avenue.

Designed by Italian architects Massimiliano and Doriana Fuksas, the 4,000-square-metre with the sinuous and futuristic spiral staircase in cream-coloured cement, had already been called by the Mayor Bloomberg as “Guggenheim Two”.

”This is not just a great architectural masterpiece but is also a vote of confidence in the future of New York as a fashion capital,” Bloomberg added at the opening.

This new Armani store held an exclusive party to celebrate the opening of Armani’s latest piece of Manhattan real estate.

A host of celebrities were present at the event included Leonardo DiCaprio, Alicia Keys, John Mayer, Josh Hartnett, Milla Jovovich, Molly Sims, Ricky Martin, celebrity stylist Rachel Zoe, Victoria Beckham, and a pregnant Mira Sorvino.

Armani created a “capsule collection” that will be available only in the Fifth Avenue, and some lucky celebs already wore it last night.

HHF Architects designed the Tsai Residence for two young art collectors.

The design reflects their request for a simple and abstract looking piece, almost without scale sitting on top of the site, which is located two hours upstate from New York City.

The whole outside of the house is wrapped with corrugated metal panels.

XTEN Architecture designed this amazing house located in the Hollywood Hills, California.

The Openhouse is embedded into a narrow and sharply sloping property, a challenging site that led to the creation of a house that is both integrated into the landscape and open to the city below.

Sou Fujimoto Architects designed this unusual house located in Oita, Japan.

The house itself is comprised of three shells of progressive size nested inside one another. The outermost shell covers the entire premises, creating an covered, semi-indoor garden. Second shell encloses a limited space inside the covered outdoor space. Third shell creates a smaller interior space.

Construction projects are grinding to a halt as financing runs dry elsewhere in the world, but in China’s biggest city, they’re still going strong.

Today, Shanghai is scheduled to officially begin work on what will become its tallest skyscraper — a 2,073-foot building in the city’s Lujiazui financial center that will tower over the current highest building, the recently completed 1,614-foot Shanghai World Financial Center.

Though China’s economy is slowing and exporters are feeling the pinch, the sinuous glass building, to be called the Shanghai Tower, is one of a slew of government-funded projects that authorities are using to stimulate growth and create jobs.

The versatile Chilean group Supersudaka designed this unusual house located in Talca, Chile.

The process was so unsteady, that all possible architectural design resources available where exercised to cope with the challenge of this house in the Chilean Central Valley.

Everything was in constant change: the program, the surface, building permits, the contractors, even the view !

Made with a metallic structure covered entirely with wood and glass, the house has been in constant change resulting a mix, a bastardized design with a patio and roof terrace.
