On the north side of Budapest, next to the ever so famous Váci street shines a streamlined facade of the prestigious OTP Bank’s brand new office, called M12. The 84,000-square-metre building’s meticulously structured floor plan evokes the rationality of the financial world. Modern office buildings are no longer just about creating workplaces for work, but about creating a working environment that fosters a culture of health and well-being. To sustain well-being, a building must meet several conditions. This project fulfills many of these requirements, including the integration of nature into the building fabric, the provision of sufficient natural light and adequate air quality, applying acoustic solutions, as well as the use of rainwater to irrigate the greenery. The intensive presence of the plants creates an exceptional atmosphere all through the building. Among others, these solutions contributed to achieving LEED Gold certification, one of the top priorities of the client.
