The massive log building is a fine example of old-time villa life. The furnishings combine romantic nationalism and more streamlined modern style. The building displays the new form ideals of its time. Functionality and comfort were more important than sumptuousness. Sonck’s design contains a traditional dining anteroom and a large dining room with auxiliary serving space, but the kitchen comes also with a separate, handy utility room.
Irma Jalanne, a daughter of the Hornborgs, designed the metal chandeliers and wall-mounted lamps, which were manufactured in her smithy/workshop in Helsinki. Some of the furniture originate from the home of Alarik Hornborg. The furniture of the master bedroom, with its owl theme, was designed by the doctor himself and commissioned from a Mr Sysimetsä, a carpentry teacher from Pori.
