Ridge height - a small definition

With the ridge height, the height is defined from the grown ground up to the outer tip of the ridge. This is important in building a house if, as is usually the case, the building height in the zoning plan has been determined.

ridge of the roof

In the case of a saddle or hipped roof, for example, the horizontally extending ridge determines the ridge height. For a tonneau roof or other domed roof shape, the vertex of the roof arch is used to determine the ridge height.


Most municipalities stipulate very precise details within their borders for the newly advertised construction areas, which must then be complied with by the building owners during the construction of the building. Thus, the ridge height or the building height is often prescribed, as there are regulations for eaves height or even the number of windows.

Nevertheless, to achieve the desired floors in the construction, it is possible to reduce the floor height. However, this is not possible in lounges or living rooms, because the minimum height is also prescribed again.

Mixed or grown structures

If you want to build today, you're in luck when you plan your own home in a construction district that has been built for centuries. Here, the ridge height is usually not mandatory, because the colorful buildings that stand there, were also not built according to a rigid plan.

Colorful street scene

The narrow development plans should produce as uniform a picture as possible of the entire road construction. There, no building should protrude from the picture, so things like ridge height, eaves height or sometimes even roofing and roof shape are prescribed.

Tips & Tricks

If you find out after construction that your building has exceeded the permitted ridge height from the development plan, you can apply for exemption from the building height. However, most building authorities will agree with this only if the exceedance is very low.
