Architecture of the United States New York City's Woolworth Building designed by architect Cass Gilbert, 1913. Raising previous technological advances to new heights, 793 ft (233 m), it was the world's tallest building until 1930. Frank Woolworth was fond of gothic cathedrals. Cass Gilbert constructed the office building as a cathedral of commerce and incorporated many Gothic revival decorative elements. The main entrance and lobby contain numerous allegories of thrift, including an acorn growing into an oak tree and a man losing his shirt. The popularity of the new Woolworth Building inspired many Gothic revival imitations among skyscrapers and remained a popular design theme until
Port of Liverpool Building with a reinforced concrete frame that is clad in Portland Stone. The building was the headquarters of the Mersey Docks and Harbour Board (MDHB) for 87 years, from 1907 to 1994, when the company relocated to new premises at Seaforth Dock. In 2001 it was sold to Downing, a Liverpool-based property developer, and between 2006 and 2009 underwent a major £10m restoration that restored many original features of the building. The Port of Liverpool Building is in the Edwardian Baroque style and is noted for the large dome that sits atop it, acting as the focal point of the building.
