Abstract
This study investigates a number of construction methods employed by architects to eliminate the visibility of a private space from the public space, which may be required due to the implementation of a housing regulation that prohibits the installation of fences around private properties. This research focuses on cases of block-type detached housing sites which have been planned in suburban areas as part of a new type of housing complex. The housing regulation was implemented to revitalize the use of streets by prohibiting the installation of fences, but it goes against the trend in contemporary society, which seeks to guard privacy by forming closed, external spaces to shut down visibility from the public space. The architectural methods used to shut off visibility include: (1) a structure which has the function of a fence built between the public space and a private space; (2) a buffer space formed between a parking lot and a neighboring property to shut down visibility from the streets leading to the external garden of a private property; (3) minimization of the opening area of the external elevation; and (4) separation of the first and second floors by designing a vertical flow of human traffic.
