Rose Center for Earth and Space, New York, US

The Rose Center for Earth and Space is a notable part of the American Museum of Natural History in New York City. The Center's complete name is The Frederick Phineas and Sandra Priest Rose Center for Earth and Space. The main entrance is located on the northern side of the museum on 81st Street near Central Park West.

The center is an extensive reworking of the old Hayden Planetarium, which dated back to 1935. An entirely new building opened to the public on February 19, 2000, featuring a seven-story-tall glass cube that encloses the 87-foot-diameter Hayden Sphere. The top half of the Sphere houses the Space Theater, one of the world’s pre-eminent planetariums, which incorporates high-resolution fulldome video to create “space shows,” based in scientific visualization of current astrophysical data.

The Big Bang Theater occupies the bottom half of the Hayden Sphere.

Solomon R. Guggenheim Museum, New York, US

The Solomon R. Guggenheim Museum opened its doors on October 21, 1959 and is one of the best-known museums in New York City and one of the 20th century's most important architectural landmarks.

the museum––which is often called simply The Guggenheim––is the permanent home to a renowned collection of Impressionist, Post-Impressionist, early Modern, and contemporary art, and also features special exhibitions throughout the year. Located on the Upper East Side in New York City it is the second museum opened by the Solomon R. Guggenheim Foundation which was founded in 1937. The Museum recently underwent an extensive, three year renovation.

The distinctive building, instantly polarized architecture critics upon completion, though today it is widely revered. From the street, the building looks approximately like a white ribbon curled into a cylindrical stack, slightly wider at the top than the bottom. Its appearance is in sharp contrast to the more typically boxy Manhattan buildings that surround it.

Internally, the viewing gallery forms a gentle helical spiral from the main level up to the top of the building. Paintings are displayed along the walls of the spiral and also in exhibition space found at annex levels along the way.

Most of the criticism of the building has focused on the idea that it overshadows the artworks displayed within, and that it is particularly difficult to properly hang paintings in the shallow windowless exhibition niches that surround the central spiral. Although the rotunda is generously lit by a large skylight, the niches are heavily shadowed by the walkway itself, leaving the art to be lit largely by artificial light. The walls of the niches are neither vertical nor flat (most are gently concave), meaning that canvasses must be mounted proud of the wall's surface. The limited space within the niches means that sculptures are generally relegated to plinths amid the main spiral walkway itself.

The museum was registered as a National Historic Landmark on October 6, 2008.

IAC Headquarters, New York, US

The building featured is located in the Chelsea neighbourhood of New York City. Completed in 2007 it houses the offices of IAC corporation. It appears at a gross level to consist of two major levels: A large base of twisted tower-sections packed together like the cells of a bee hive, with a second bundle of lesser diameter sitting on top of the first. The cell units have the appearance of sails skinned over the skeleton of the building. The overall impression is of two very tall stories, which belies its actual 10-storey structure.

Vanity Fair, writing about IAC corporation, argued that this is perhaps the world's most attractive offices.

Lipstick Building, New York, US

The Lipstick Building (also known as 53rd at Third) is a 453 foot (138 meters) tall skyscraper located at 885 Third Avenue, between East 53rd Street and 54th Street, across from the Citigroup Center in Manhattan, New York City, United States. It was completed in 1986 and has 34 floors.

At three levels, blocks of the building recede as part of a building regulation in which the building is required to recede at least three times to increase the availability of light to street level. The shape, which is unusual in comparison to surrounding buildings, uses less space at the base than a regular skyscraper of quadrilateral footprint would use. This provides more room for the high numbers of pedestrians who travel via Third Avenue.

At the base, the building stands on columns which act as an entrance for a vast post-modern hall. They are two stories high and separate the street from the nine meter high lobby. Because the elevators and emergency staircases are located to the rear of the building, this area is "hollow".

The exterior of the building is a continuous wall of red enameled Imperial granite and steel. The ribbon windows are surrounded by gray frames. In between each floor is a small line of red which is taken from the red color of lipstick. The curvature of the building allows light to reflect off the surface at different places.

Hearst Tower, New York, US

Hearst Tower in New York City, New York, US is located at 300 West 57th Street, 959 8th Avenue, near Columbus Circle. It is the world headquarters of the Hearst Corporation, bringing together for the first time their numerous publications and communications companies under one roof, including among others Cosmopolitan, Esquire and the San Francisco Chronicle.

The former six-story headquarters building was commissioned by the founder, William Randolph Hearst and awarded to the architect Joseph Urban. The building was completed in 1928 at a cost of $2 million and contained 40,000 sq ft (3,700 m2). The original cast stone facade has been preserved in the new design as a designated Landmark site. Originally built as the base for a proposed skyscraper, the construction of the tower was postponed due to the Great Depression. The new tower addition was completed nearly eighty years later, and 2000 Hearst employees moved in on 4 May 2006.

The tower, structural engineered by WSP Cantor Seinuk, and constructed by Turner construction is 46 stories tall, standing 182 m (597 ft) with 80,000 m² (856,000 ft²) of office space. The uncommon triangular framing pattern (also known as a diagrid) required 9,500 metric tons (10,480 tons) of structural steel – reportedly about 20% less than a conventional steel frame. Hearst Tower was the first skyscraper to break ground in New York City after September 11, 2001. The building received the 2006 Emporis Skyscraper Award,[2] citing it as the best skyscraper in the world completed that year.

Hearst Tower is the first "green" high rise office building completed in New York City, with a number of environmental considerations built into the plan. The floor of the atrium is paved with heat conductive limestone. Polyethylene tubing is embedded under the floor and filled with circulating water for cooling in the summer and heating in the winter. Rain collected on the roof is stored in a tank in the basement for use in the cooling system, to irrigate plants and for the water sculpture in the main lobby. The building was constructed using 80% recycled steel. Overall, the building has been designed to use 26% less energy than the minimum requirements for the city of New York, and earned a gold designation from the United States Green Building Council’s LEED certification program.

The atrium features escalators which run through a 3-story water sculpture titled Icefall, a wide waterfall built with thousands of glass panels, which cools and humidifies the lobby air.
