We were tasked with creating the most comprehensive condition assessment possible for this listed historic building, serving as a foundation for future renovations and developments. This involved not only a complete survey but also a full-scale technical due diligence, incorporating every relevant professional discipline. The result is a detailed BIM survey model and a 300-page summary of the building's technical condition and values, including short-, medium-, and long-term CAPEX calculations and a complete data room inventory. It is regrettably rare for a development plan to be provided with such a comprehensive foundation.
By this time, we already had significant experience in surveying sensitive, occupied historic buildings. As always, we carried out the on-site work under constant supervision, adhering to banking operational and security protocols while adjusting to the daily schedules of the staff. We processed the entire building, including the facades and representative interior spaces, using laser scanning and software such as Archicad and Rhino. Archicad provided the BIM structure and documentation capabilities, while Rhino allowed for the detailed modeling of intricate, historical architectural elements. The resulting digital dataset provides a reliable, precise source of information for all future renovation, restoration, and operational processes.

The history of the building is impressive in its own right. When the bank headquarters was inaugurated in 1912, it was among the most modern and imposing buildings in Budapest. Designed by Albert Kőrössy and Géza Kiss, the building was constructed in an eclectic style that incorporates both Renaissance and Art Deco elements. Its exterior is enriched by agricultural motifs symbolizing reliability and prosperity—such as sculptures of a woman with a beehive and harvesting men—which refer to the activities of the building's original owner, the Hungarian Agricultural and Annuity Bank. The interiors reflect a harmonious combination of understated grandeur and technical innovation. At the time, the building featured the most modern technical solutions, such as elevators, central heating, pneumatic tube systems, and a paternoster lift, which is now considered a rarity but remains in operation today. The legal predecessor of OTP Bank, the National Savings Bank, has occupied the building since 1951. Nádor utca 16 is not only an important site in Hungarian banking history but also of outstanding significance due to its heritage value, embodying the economic and cultural legacy of downtown Budapest.
