A bungalow is a type of building, originally developed in the Bengal region in South Asia. The meaning of the word bungalow varies internationally. Common features of many bungalows include verandas and being low-rise. In Australia, the California bungalow associated with the United States was popular after the First World War. In North America and the United Kingdom, a bungalow today is a house, normally detached, that may contain a small loft. It is either single-storey or has a second storey built into a sloping roof, usually with dormer windows (one-and-a-half storeys).Bungalows are very convenient for the homeowner in that all living areas are on a single-storey and there are no stairs between living areas. A bungalow is well suited to persons with impaired mobility, such as the elderly or those in wheelchairs. Bungalows in the Inman Park neighbourhood of Atlanta, Georgia, United States Neighborhoods of only bungalows offer more privacy than similar neighborhoods with two-storey houses. As bungalows are one or one and a half storeys, strategically planted trees and shrubs are usually sufficient to block the view of neighbors. With two-storey houses, the extra height requires much taller trees to accomplish the same, and it may not be practical to place such tall trees close to the building to obscure the view from the second floor of the next door neighbor. Bungalows provide cost-effective residences. On the other hand, even closely spaced bungalows make for quite low-density neighborhoods, contributing to urban sprawl. In Australia, bungalows have broad verandas to shade the interior from intense sun. But as a result they are often excessively dark inside, requiring artificial light even in daytime.
