Beginning in 1998, Hong Kong entered a second, much larger building boom that lasted until the early 2010s. The second boom saw the completion of the International Commerce Centre, Two International Finance Centre, Nina Tower I, and One Island East. At the height of the construction boom in 2003, 56 skyscrapers over 150 m (492 ft) were completed throughout the city. The proliferation of multi-tower, high-rise building complexes, such as public housing estates and transit-oriented developments near MTR stations (known as rail + property development), greatly increased the number of skyscrapers.
