Abstract: The invention relates to a method and a system for producing a building, which comprises at least one building subunit. In this case, technical boundary conditions for the production of a building are first generated in that a development area and country-specific building specifications are recorded and/or analysed. On the basis of the technical boundary conditions, a building plan is created via a client-server model, a server device generating a building specification optimized for the technical boundary conditions via an algorithm of the harmonic search. Building measures for the building to be built are finally initiated on the basis of the building plan.
