The three-hundred-year-old buildings in the historic center of Zalopan, adjacent to the historic center, have been renovated with special care and turned into a modern, comfortable office center. The superstructure of the attic from above was supplemented with soothing and calm facades, uniting the differences behind the elements together. The houses did not waste their historical image, but successfully engaged in additional functional and concise details. The design of armchairs with a curved arch deserves special respect.
