What are the types of houses in Korea?
There are four main types of housing in Korea: "apateu" (아파트, apartment), villa, officetel, and house. An "apateu" is a multi-room unit in a high-rise condominium used strictly for residential purposes. An officetel is a smaller residential unit in a high-rise mixed-use (residential and commercial) building. Villas are low-rise townhouses, while single detached houses are usually found outside the cities. Of these, villas are the cheapest option, but lack standard security services/facilities.
If you choose a villa or officetel, you may encounter terms like "one room", "1.5 room", or "double room." "One room" refers to a studio unit with no separate bedroom, "1.5 room" is a living space with one separate bedroom, and "double room" is a living space with two separate bedrooms.
