The basic design is modeled on the typical highlander hut with a vestibule at the entrance (here: the dining room), the ‘black chamber’ on the left (salon), and the ‘white chamber’ (sleeping room) on the right side. Apart from those rooms, the villa houses an office, a library, a kitchen, and a usable attic. In Harenda villa, both the dining room, salon, sleeping room and Władysław Jarocki's (Kasprowicz's son in law) art gallery are available for touring.
