Of the total area, 1,073 km2 (414 sq mi) is land and 35 km2 (14 sq mi) is water.[5] The territory's highest point is Tai Mo Shan, 957 metres (3,140 ft) above sea level.[6] Urban development is concentrated on the Kowloon Peninsula, Hong Kong Island, and in new towns throughout the New Territories.[7] Much of this is built on reclaimed land, due to the lack of developable flat land; 70 km2 (27 sq mi) (six per cent of the total land or about 25 per cent of developed space in the territory) is reclaimed from the sea.[8]
