If plots of land or houses are offered for sale, a detailed site plan must also be drawn up. This is also known as the official site plan and is part of the building application. It consists of a graphic and a written part. The written part contains a description of the property, the neighboring properties and the building encumbrances. The builder is also listed here.
The base and floor areas as well as the building dimensions are also mentioned. The scale 1:200 or 1:500 is often used for the graphic part. Here you can see the outline of the planned building from above (so-called plan view). The shape and inclination of the roof as well as the distance areas are also recorded in the drawing. The adjoining properties are also shown here.
For example, some brokers put these site maps in the online real estate advertisements. In this way, an interested party can find out about the location of the property in advance. For example, does he prefer a location on the outskirts of the city or would he rather live right in the center? The site plan provides the desired information for the plots of land released for development or for existing buildings.
The official site plan is enormously important, as it represents a decisive basis for the first building template, for which a preliminary urban planning decision is then drawn up, but also for the building notification process and for the granting of the building permit itself.
Who is allowed to create an official site plan?
The official Site plan can be created by a publicly appointed surveyor, another expert in surveying or an authority equivalent to this group of people. The basis for this is the official cadastral map, which is also referred to as a field map, but also our own measurements, for example in the context of checking property boundaries.
What does the site plan include?
The official position and elevation reference system is used to produce the site plan. The main content of the official site plan can differ somewhat between the individual federal states. The Brandenburg building site ordinance, for example, provides for the following main contents in § 3 para. 2:
- Property location to the north,
- Designation of the building plot listed in the land register, but also of neighboring properties including information on their owners,
- Cadastral area sizes and parcel numbers and boundaries of the respective building plot and the neighboring plots,
- Altitude of the border points of each building plot, for larger plots of land the altitude of the then narrower building plot,
- Directly adjacent public traffic areas (information on the width, the street group and the altitude must be provided here),
- Determination of a development plan or a statute for the respective building plot with information about the type and extent of the structural use, information about the plot areas that can be built on and the plot areas that cannot be built on,
- Information on areas on this property that are affected by building encumbrances or so-called easements,
- Landscape components or forest on the building site, which are protected by a statutory order or statute,
- Structures already existing on the building site, their clearance areas and an assessment of structures on neighboring properties, insofar as these are important for the new building project.
In coordination with the architect, the following information can also be shown in the official site plan:
- Planned structures, for which the external dimensions, the roof shape, the boundary distances and clearance areas, the height of the ground floor to the street, the location and the width of the entrances and exits are to be shown,
- Listed buildings or building components,
- Natural monuments, protected landscape components, protected biotopes on the property to be developed or on the neighboring properties,
- High voltage power lines and
- Other facts those are important for the construction project.
The official site plan serves as the basis for further plans, which are to be submitted with the building template. The object planner uses the site plan to create the so-called object-related site plan, the property drainage plan and the outdoor area plan. If the official site plan already reflects this information, it can replace these plans.
