AP (Thailand) Public Company Limited was established in 1991 to develop residential projects in Bangkok Metropolitan Area (BMA) by Mr. Anuphong Assavabhokhin and Mr. Pichet Vipavasuphakorn as major shareholders. In 2000, the company did a backdoor listing thru PCM Public Company Limited (PCM), a listed company in the Stock Exchange of Thailand since 18 January 1994, and changed its name to "Asian Property Development Public Company Limited (AP)". Prior to the merger, PCM, a precast concrete floor manufacturer, was mainly owned by Land and Houses Plc. (LH).

Since the merger between Asian Property and PCM on 23 November 2000, Asian Property Development set a new company, called PCM Construction Material Company Limited (PCMC), 100% owned, manufacturing precast concrete floors.

In early 2004, AP sold all shares in PCMC to Pre-built Plc., a contractor company and increased its shares in Pre-built Plc. from 19.8% to 64.73%. In 2005, AP adjusted its structure to focus particularly on property development by reducing its shares in Pre-Built from 64.73% to 43.82%, 24.02% and, as of 30 June 2010, 19.96%. On 23 February 2010, AP sold its entire shares in Quality Construction Products Plc. to SCG Building Materials Co., Ltd. Consequently, AP no longer holds a share in Quality Construction Product Plc.
