Eaves
As eaves , short eaves (from Middle High German troufen "let drip, drip"), the drip edge at the roof of a building designated. During rain, the water collected on the roof runs off here, so there is usually a gutter at the eaves in areas with high levels of rainfall . The length of the eaves corresponds to the width of the roof area. The area of the roof between the outer wall of the building and the eaves is the " roof overhang ".
The eaves limit a sloping roof surface downwards - the upper limit is the " roof ridge ". The lateral boundaries are called " verge ", " ridge " and " throat ".
Eaves point and height
The “eaves point” is the point of intersection between the vertical outer surface (surface of the outer wall) and the roof cladding . The height between the eaves point and the terrain is called the "eaves height" .
As a limiting measure in building planning law, the eaves height does not necessarily correspond to the height of the gutter above the ground at every point, but is averaged or determined graphically. The maximum eaves height can be stipulated in a development plan ; in Berlin , for example, a traditional eaves height of 22 m often applies. In the development plan, a maximum eaves height can also be determined depending on the roof pitch. B. for single-storey houses 3.5 m with 45 ° roof pitch and 4.0 m with 35 ° roof pitch. In addition, the ridge height is also generally determined, which leads to further restrictions on the eaves height.
The reference points of the eaves height definition generally relate to the upper edge of the public road and the point of intersection between the rising masonry, the outer wall, and the rafters. Here, too, the development plan can specify whether the lower edge of the rafter or the roof skin are decisive. Roof structures do not trigger eaves heights in planning law. The eaves height is always connected to the ceiling of the last possible full floor and the rising outer wall.
Eaves right
If the owner of a property has the right to let the rainwater drain onto the property of the neighbors, one speaks of an eaves right. This right has nothing to do with the eaves right.
Eaves
The term "eaves" refers to the orientation of a building in relation to an accessible street or square. In the case of an eaves construction, the eaves (and the ridge) of a building are parallel to the street. The opposite term in architecture and urban planning is "gable-independent".
