Internet-assisted information platform for building land activation
(Berlin)

Author: Senatsverwaltung für Stadtentwicklung
The Berlin Senate Administration of Urban Development is responsible for urban planning, engineering and building activities, housing, the environment and traffic issues. This is where the information system “City and Environment” (Stadt und Umwelt) was created in 1998. Within this interdisciplinary task area, the development of a so-called “FIS-Broker”, a networked “interdisciplinary information system”, was started in 1999. In order to facilitate structural investments in unexploited but developed plots and hence promote interior development, an “online management for gaps between buildings” was devised on this technical foundation.

The electronic information system „gap management“ represents a special service supplied by the Berlin Senate Administration and district authorities in order to increase the transparency of the real estate market. Extensive information on vacant or underused areas is made available on a data base-assisted internet site. The information is augmented by maps, spec sheets, legal planning data and photographs. The owners are given an opportunity to advertise their properties on the Senate Administration's website, including their (email) address or links to their homepage. Website users, e. g. investors, architects or prospective builder-owners, can research potential areas featuring specific location factors using a detailed search grid.
The data are compiled and processed by district town planning authorities. It was also possible to make use of already existing data such as the „automated property map”, the digital preparatory land-use plan and aerial photographs. These databases were interlinked via the "interdisciplinary information system" (called FIS-Broker, for “Fachübergreifendes Informations-System”) and therewith made available in their entirety.
The Senate Administration of Urban Development conceived the „online management for gaps between buildings“ concept, extending it in stages. Starting in February 2001, all plots owned by public bodies (federal state, state, property funds, housing societies etc.) and suitable for building within the pilot district of Friedrichshain-Kreuzberg were entered. Since July 2002, all public and private development gaps within the inner tram circle are being registered and made available for research – adding up to over 800 individual sites with an overall area of 220 ha. The amenity was publicized via advertisements in the daily press and Berlin’s official gazette. The site owners were given the opportunity to contradict the publication but have not done so in a single case. The information supplied is updated regularly by district authority building consultants.
The website registered approximately 90.000 hits in the first year. The number of areas „activated“ so far is limited, not least owing to the stagnation on the Berlin real estate market. But according to estimates regarding the pilot district Friedrichshain-Kreuzberg, at least 1/3 of the areas have “stirred” since being made available online, i. e. have been the subject of preparatory building enquiries or building applications, respectively, or even of purchase negotiations or sales. Several properties have consequently been removed from the database. Besides the online presentation, the project “development gap management” provides caseworkers in district town planning authorities with the modules “database” and “map” for the efficient management of building land.

This instrument uses the latest information technologies to combine sovereign planning information with market knowledge in the pursuit of local land policy. Databases from various sources, some of them difficult to access, were bundled, processed and made available to the public. The project represents an innovative, user-friendly promotion strategy for interior development.
