Flexible societies require flexible environments. Due to economical, ecological and social reasons it can be more efficient taking advantage of existing architecture rather than creating new buildings. A Web based information system is proposed which can support the distribution of information for ‘temporal available space’ for providers and users. Potential providers are able to store their space information via Internet. While users can request information about required locations. Examinations made in an eastern Berlin district have shown that information based management for space and time is improving the efficiency of using existing environment. Furthermore schools, garages, shops and unused facilities can become attractive locations for social events.
