The estate was built in 1895 by a Sumy merchant of the 2nd guild, Nikolai Alekseevich Sukhanov (nephew of the Sukhanovs, local merchants and industrialists). At that time, the complex consisted of three buildings - the main residential two-story building with architectural decorations (now the Institute of Applied Physics), an office building (now the building of the Banking Academy) and a long one-story service building (now the Organized Crime Control Department is located there). By the beginning of the 20th century, the estate was equipped with the latest technology of that time, even electric lighting was installed.→
