The palace-type building built by Nicholas von der Nonne is his first and last attempt to use volume-spatial solution by actively using plastic tools. This is sole historical building, which is perceived as a three-dimensional construction of flat-sized buildings in Baku. After re-planning the surrounding areas of the city, De Boure's palace remained an exemplary building. Significant size and effective location make up a composite accent between successfully constructed buildings. It is noted that the quiet, horizontal divisions of the palace creates a harmony with the surrounding club building, Building of Mayoralty of Baku and verticals of the property of Sadikhov. During projection of the Palace of De Boure, the squares along the red lines of the street were empty. Concerning this, the architect, Nicholas von der Nonne, paid special attention to the harmony of buildings in the neighborhood while working on the project. Considering the special position of the palace and the location, closeness to the Caspian Sea, large and plastic solutions are interesting. The baroque-style architecture of the palace, the well-placed classic elements and the powerful plastic tools (porticoes) used in the background of building using unhewn stone have an important role.
