The aim of the pre-study is to analyze parts of the interior of the Pragovka building to accommodate the newly developed concept of a co-working office space. We distinguish 4 main spatial behaviors in today’s office spaces: FOCUS, SOCIALIZE, LEARN and COLLABORATE – collaborating with others. We define the main functions in an office / cowork interior. The functions are in a mutual synergy. The main functions (considered as leasable areas) such as coworking places, dedicated desks, private offices and leasable meeting rooms are complemented by non-leasable functions. These are important in the overall setup, because they provide a space with all the possibilities mentioned above. The proper mix of all these functions and their proper spatial distribution form a successful coworking space. For every function we define a specific volume / box / furniture type. These elements carry various roles in the interior concept. They act as natural paravans – space dividers. They enable people to orientate in the space and they are carriers of information and navigation graphics. They scale down the space into more comfortable units of approximately 25 to 50 sqm. These elements are either freestanding or attached to existing partitioning, nor site- specific. They can be distributed in any available interior.
