http://www.ka-tours.org/ From the website July 5, 2011:
Khmer Architecture Tours started as an independent, not-for-profit organisation in 2003 in Phnom Penh and is now a part of Space for Architecture (www.spaceforarchitecture.org). The aim of KA Tours is to promote the understanding of modern architecture in Cambodia.
In addition to arranging tours and guiding, we research buildings and provide training in preparing data about important buildings. Founded by Geoff PYLE, KA Tours’ guides/researchers are all Cambodian architects and students of architecture. The Director is Stefanie IRMER. Our guides are SIM Sitho, YAM Sokly, SEREY Pagna and YAN Vivoath.
Funds raised by donations or tour fees are directly channeled into covering costs of the tours, which includes guide’s fees, as well as sponsoring other educational activities such as lectures.
They have available several detailed walking tours of Phnom Penh.
