Flats can be classified into several types. One being a Studio, efficiency, bedsit, or bachelor style flats. These all tend to be the smallest flats with the cheapest rents in a given area. These kinds of apartment or flat usually consist mainly of a large room which is the living, dining, and bedroom combined. There are usually kitchen facilities as part of this central room, but the bathroom is its own smaller separate room. Moving up from the efficiencies are one-bedroom flats where one bedroom is a separate room from the rest of the apartment. Then there are two-bedroom, three-bedroom, etc. flats. Small flats often have only one entrance/exit. Large flats often have two entrances/exits, perhaps a door in the front and another in the back. Depending on the building design, the entrance/exit doors may be directly to the outside or to a common area inside, such as a hallway. Depending on location, flats may be available for rent furnished with furniture or unfurnished into which a tenant usually moves in with their own furniture. A garden apartment or flat has some characteristics of a townhouse: each apartment or flat has its own entrance, and apartments are not placed vertically over one another. However, a garden apartment or flat is usually only one story high and never more than two stories; they are often one-bedrooms and almost never more than two-bedrooms. Some garden apartment or flat buildings place a one-car garage under each apartment, with pedestrian entrances from a common courtyard open at one end. The grounds are more landscaped than for other modestly scaled flats. Alternately, “garden apartment” can refer to a unit built half below grade, putting its windows at garden level.
