Guest Rooms are rooms that are inserted externally into buildings halfway up and are accessible only from the outside. A Guest Room can be reached e.g. via a rope ladder or retractable stairs. Guest Rooms are offered by the most diverse buildings, such as churches, banks, shopping centers, private homes. A Guest Room is not linked to the rest of the building. Guest Rooms are autarkic. Guest Rooms merely utilize the volume of existing buildings (in programmatic as well as in tectonic terms) as construction sites, as anchorage, to hold them in place.
In some types of construction, the volume of the Guest Rooms will also be visible from within the building, e.g. in churches, even in coffee bars; in others, however, the Guest Rooms will be completely hidden from view by the building's fabric and functional volume, for instance in residential and office buildings.
Guest Rooms constitute a kind of offering to the public on the part of developed urban space. It is a gesture akin to putting out a bowl of rice for imaginary deities.
A Guest Room may also be a Green Room, in other words a Guest Room for plants, for instance.
The size of a Guest Room equals at least that of a hotel room. A Guest Room provides drinking water for the visitor.
From the first half of the 21st century onwards, Guest Rooms will gradually be introduced into cities at ten minutes walking distance from one another. They represent a kind of tax. Guest Rooms are the most luxurious rooms available in a city.
