In the plan the lobby of the house is shaped as a regular octagon. Luxurious, glazed doors with skylight windows have been created in the four walls of the room.
The other four walls above the wooden panels reveal the painted landscapes of the four Vidzeme castle ruins from tsarist times (Vastselina, Turaida, Koknese and Cesis).
In the center of the room there is an eight-branch brass chandelier made in 1775. Intricate vignettes with the coats of arms of 16 cities have been restored on the ceiling.
Both the lobby and the staircase have teracco floors, made in 1888 by Italian masters from Johor Odorico in Frankfurt am Main.
An interesting detail of the interior decoration are the ancient German aphorisms, expressions and “grains of thought” in Gothic font and saturated with ancient German terms, located in practically all of the rooms.
These inscriptions serve as a unifying component of interior decor, as an ornament with artistic value, similarily to Arabic script, which only a few can read.
