The White Building, originally known as the Municipal Apartments, was a large and prominent apartment building in Phnom Penh, Cambodia, one of the buildings in the Bassac development, on Samdach Sothearos Boulevard near the Bassac River, a large urban extension project built on reclaimed land in the early 1960's. The UN consultants Gérald Hanning and Vladimir Bodiansky introduced the concept of the building, a architectural composition, directly inspired by previous AT.BAT designs built in Morocco. Lu Ban Hap, then Chief Architect of the Municipality of Phnom Penh, was responsible for the site supervision. The White Building was designed to house moderate-income tenants, and was adopted by many artists who found the innovative design appealing. The nearby Grey Building, designed by Vann Molyvann, initially built for athletes in the 1964 GANEFO international sports event. After years of neglect and deterioration since the fall of the Khmer Rouge, the building was demolished in 2017. The building is composed of six blocks of concrete construction, three or four stories tall, connected by open bridge structures, along a double-loaded spine. It included stores and doctors' offices as well as 468 apartments. Tenants fled during the Cambodian genocide in the 1970s. After the defeat of the Khmer Rouge in 1979 the White Building was reoccupied by former tenants and squatters. It gradually declined and became known for poverty, drug use and prostitution. Its population in 2015 was about 2500. According to municipal authorities, the building is structurally deteriorating and is unsafe. Tenants have used the high-ceilinged rooms to add lofts, and balconies have been enclosed, obscuring the once-white building's design and also adding weight to the structure. Cracking appeared in 2015 after construction on an adjoining lot. Several proposals have been made to tear it down for redevelopment. Eviction orders were issued in July 2015. However, the building's status as an iconic New Khmer building has stimulated preservation efforts. In July 2017, the almost 500 families still living in the White Building were moving out; the building is to be replaced by a 21-storey mixed-use development.
