Since the beginning of history, human beings have made great advances in technology. In the field of architecture, this movement has had reflections such as new construction and application techniques and the use of different materials. In parallel with this rapid progress in building and construction technology, solutions that meet the changing needs in architectural design have started to be offered. Aim: The aim of the research is to find out which plan type is the most preferred in terms of design in high-rise office buildings in Eskişehir road region, which attracts attention with its office building stock in Ankara, and to analyze the relationship of this plan type preference with the building's height and current value parameters. Method: Tracing method was used to find the ratio of plan types in the examined office buildings and to establish the relationship of these plan types with height and m2 current value. Then the obtained data were evaluated statistically and regression values were found by using regression analysis method. Results: In the 12 office structures examined in the study, open office (47%), mixed office (27%), closed (13%) and co-working offices (13%) were preferred, respectively. 66% of the multi-storey office buildings in the sample space of the research have a height of 100 m or more. Closed offices are the lowest value in terms of market value and mixed offices are the highest valued. Conclusion: It is understood that open-plan offices are preferred in the Ankara Eskişehir road region. As a result of the study, it has been revealed that these plan types, which are mostly used in office buildings, have a directly proportional relationship with the concept of current value per m2, but not with the height of the multi-storey building. In this respect, it is possible to say that architectural design decisions directly affect the real estate market of the country and this interaction has formed an important relationship with the country's economy by shaping the capital market.
