The Greenhouse and the Cavalier's House are located at the eastern end of the palace garden. This part of the garden is designed in the style of an English landscape garden.
The Cavalier's house was built in 1840 as a rectangular two-storey construction in load-bearing masonry with a stucco façade. The roof is designed as a flat pitched gable roof. The design features classicist stylistic elements, such as the triangular gable. A circumferential belt cornice was applied at the level of the storey ceiling.
The round-arched windows with mullions and fixed fanights are set on the cornice of the base and those of the upper storey are set on the plinth course. The round-arched windows are continued as blind windows to preserve the symmetry of the façade. The corners of the ground floor of the Cavalier's house are rusticated, the building corner on the upper floor is reduced in its design and emphasised by pilasters. Today, the Cavalier's house is a private home.
