Increase (architecture)
In the construction industry, the addition of one or more additional floors or full floors to an already existing building is called an extension (also saddling up ) . In contrast to the attic extension , it is not about the interior construction of an existing attic space within the cubature of a building, but about an increase. Additional space is created and the gross floor area of the building is increased without the need for additional areas to be built over ( surface sealing ).
Increases are characteristic of situations of growing pressure to build, for example as a result of the increase in population in walled cities or in favorable urban areas. The change in the cityscape from gable-free to eaves-free development in the major cities of the 17th and 18th centuries (e.g. in Paris and Vienna ) was essentially the product of additions.
Increases can raise questions of statics and fire protection, but also the maintenance of the site and monument protection . It is often discussed whether the design should correspond to that of the existing building or whether a contemporary architectural language should be chosen.
