The collective housing buildings are usually inflexible in the exploitation phase because of inflexible building structure. Inflexible structural model is composed of components and subsystems, more or less joined together into complex relations and fixed connections. Such physical relations stand as a limitation for elements to be replaced at the end of its service life and for the structure to be upgraded. Changes at the building level of 'static' systems are related with time and money consuming by long transformation processes, significant energy and material lose and enormous amount of waste production. The term transformation is introduced for dynamic changes in building structure on spatial, technical and material level. After each use phase, systems' configuration should be assembled to indicate building suitability for transformations according to new changing requirements. Open configuration model, based on independent and exchangeable components and subsystems, applied for more permanent building parts like load-bearing structure, enclosing, services' systems, may become the solution for the new dynamics in building structure. We will consider more specifically how controlled hierarchies, based on independency and systematization of elements in different technical levels, provide a context for flexibility in buildings. Technical composition of systems' configuration will be presented as a graph model. Graph model is a description for systems' configuration model to support systematization of structural elements into open hierarchy assemblies, based on edges between nodes and clusters. The cluster is an assembly of nodes (components) that perform the same function. The 'edge' is a demountable connection between nodes and clusters. Finally this research is about systems' configuration model for building structure with special focus on: 1) more flexibility of long-lasting building parts 2) integrated model based on coordinated relations-edges, between assemblies-clusters 3) more transformation capacity of integrated systems and components; 4) configuration ability to transform according to demountable joints.
