THE CONTRUCTION OF THE PALACE
          The Department of Public Works was responsible for designs and construction of the palace under the supervision of Phra Sathit Nimankarn.  The construction projects for the Department of Public Works during that time had Senior Architect Mr. Carl Zundrekski assisted by Mr. Paolo Remedi and Mr. Mario Tamagno in charge of architectural designs while Chief Engineer Mr. Carlo Allegre and Assistant Engineer Mr. Elmigno Gioanni Ugegno Gollo were responsible for structural engineering.

              THE ARCHITECTURE
          In the course of designing the Bang Khunphrom Mansion, Europe was going through the period of change. With the Industrial Revolution, new materials were discovered influencing new movements of designs and construction methods. The manifestation of the Bang Khunphrom Palace was therefore the result of such movements and discoveries with bricks and concrete wall bearing system. The Mansard roof with dormers placed evenly was covered with interlocking tiles and supported by solid wood structure.
           The Main Bang Khunphrom Mansion stands proudly in its unique elegance ornamented by delicate stucco designs considered to be one of the most beautiful in Thailand. The stucco designs borrow from various western periods and styles and yet blend harmoniously with the architectural character predominated by Baroque style so evident in external walls.
          The South Wing of the Mansion is rounded out with a circular tower while each section of the wall facing the Northeast wears an arch trimming on top. The overall floor plan is typical of the Baroque Period that remained popular into the late 19^th century. The decorative motifs found in different rooms correspond with each other accentuating stucco designs around window frames and light portholes. Most outstanding features of the interiors are the panelled door with intricate etching in the center, the porthole above the door blinded with laced wood, carved wood decorations with designs painted in gold on the ceilings and glossy interlocking teakwood floor.
