The term ‘bungalow’ is very often misused by Malaysians, even those who speak good English. The same is true for Singaporeans.
So what is a bungalow? The definition from Wiktionary is as follows:
bungalow (plural bungalows) A small house or cottage usually having a single story.
A bungalow is a relatively small house, which is either one storey, or has a second storey built into an attic area (space above the ceiling), containing a dormer window (effectively one and a half storeys). However, a bungalow does not have two stories, and a two-storeyed house cannot be called a ‘bungalow’
Here is a picture of a bungalow:
The correct term for what Malaysians erroneously call a “bungalow” would be a “two-storeyed house” or a “detached house” (one that is not connected to the house(s) beside it).
