Question: Which project is older the Woolworth Building or 80 Flatbush?
Context: 90 West Street (alternatively West Street Building) is a building in Lower Manhattan, New York City.  It was designed by architect Cass Gilbert and structural engineer Gunvald Aus for the West Street Improvement Corporation.  When completed in 1907, the building's Gothic styling and ornamentation served to emphasize its 23-story height, and foreshadowed Gilbert's later work on the Woolworth Building.  Originally built as an office building, the main tenant was the Delaware, Lackawanna and Western Railroad and the top floor was occupied by Garret's Restaurant, which advertised itself as the "world's highest restaurant". 80 Flatbush is a mixed-use development encompassing two towers, proposed for the Brooklyn borough of New York City by Alloy Development.  The site is in Downtown Brooklyn near Boerum Hill and Fort Greene.  The completion of the project is contingent on the rezoning of the site owned by Alloy. Rubin Schron, who goes by Ruby, is a New York City real estate investor, landlord and the founder of Cammeby's International Group.  He has a personal net worth of well over $10 billion, according to data company Real Capital Analytics.  The portfolio of Cammeby's, which Schron founded in 1967, includes office buildings, market-rate and government-subsidized apartment complexes, nursing homes, the 16-building complex in Sunset Park now known as Industry City, a stake in the bottom half of Woolworth Building and industrial properties scattered across Long Island.  In 2013, Schron made an unsolicited and unsuccessful offer to buy the Empire State Building for $2 billion, but he has not had problems closing many other deals throughout his long career.  In 2003, an investment group led by Schron paid $600 million for a portfolio of about 6,000 outer-borough apartments from Donald Trump.  Other buildings he owns include the Monterey, a 521-unit rental multifamily building on Manhattan's Upper East Side; over the decades, Schron has also amassed a portfolio of Mitchell-Lama apartment buildings whose values have been skyrocketing to record values, after reverting to market rates when government subsidies expired.  In 2007, he sold nearly 4,000 units of former Mitchell-Lama properties in five complexes in Harlem and on Roosevelt Island for $940 million.  Schron, who practices Orthodox Judaism, has eight children and 50 grandchildren.  He and his family have lived in the same single-family home in Brooklyn for many decades. The Petroleum Building (formerly known as the Hogan Building) is a highrise in downtown Midland, TX.  The building was built in 1928 and consists of 12 floors and has a neo-gothic style architecture to it.  The building stands at 137 ft but with its spires reaches a height of 151 ft. The Hogan building is a registered, Texas historical landmark.  The tower is named for lawyer and oil entrepreneur Thomas Stephen Hogan.  For information on Hogan, see article on Jacob Bunn.  The design of the Petroleum Building, like the Woolworth Building in New York City and the Baum Building in Oklahoma City, utilizes many classic architectural devices.  Gothic spires and Moorish arches, lavish carved surfaces and opulent marble, all intended to clothe the business house with the respectability of a cathedral.  Thomas Stephen Hogan intended his building to be a landmark and (Fort Worth architect-engineer) Wyatt Hedrick designed a building that people would talk about.  However, behind the ornate cast-stone façade was (sic) functional reinforced concrete, the finest equipment available, and the determination of one man to establish Midland as the headquarters of the West Texas oil fields.
