The neighbourhood roughly encompasses the Trafalgar[1] and Compassvale subzones of the Hougang and Sengkang Planning Areas respectively, as designated by the URA.

[2] The namesake road Lorong Buangkok was named Buangkok, meaning "ten thousand countries", after the rubber plantation company Singapore United Rubber Plantations Limited's Chinese name "Multi Nations" (万国) in Teochew.

Today, Lorong Buangkok is truncated into two sections — one located at the west end of Buangkok with its entrance near Yio Chu Kang Road, and the other much shorter section located within Sengkang near Punggol Road.

The final extension from Buangkok Link to Yio Chu Kang Road has also started construction, and will be completed at an unknown date in the near future.

[5] A new bus interchange,[6] which is part of a mixed, integrated development called Sengkang Grand Residences & Mall,[7] is being built at the empty field in front of Compassvale Ancilla Park, is due to be completed by 2024, with LTA announcing that it would start operations on 1 December 2024.
