TYPES OF BUILDING

There are 2 main types of building:
1. Residential
2. Multi-Storey

RESIDENTIAL
Residential buildings are called houses/homes. Single family and multi-family dwellings are typically built as shelter and living space. These building types may range from one-room wood-framed, masonry, or adobe dwellings to multi-million dollar high-rise buildings able to house thousands of people. The definition of a low-rise vs. a high-rise residential building is being debated, but generally three stories or less is considered low-rise. -reference : www.wikipedia.org

MULTI-STOREY
A multi-story building(American English, Multi-storey Building British English) is a building that has multiple floors (stories (storeys in British)) above ground in the building.
Multi-story buildings aim to increase the area of the building without increasing the area of the land the building is built on, hence saving land and, in most cases, money (depending on material used and land prices in the area, of course). - reference : www.wikipedia.org
