THE CONTRUCTION OF THE PALACE
The Department of Public Works was responsible for the designs and construction of the palace under the supervision of Phra Sathit Nimankarn. The construction project under the Department of Public Works during that time had Senior Architect Mr. Carl Sandreckzki (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.
During the course of designing Bangkhunphrom Palace, Europe was going through a period of change. With the Industrial Revolution, new materials were discovered which influenced new movements of designs and construction methods. The manifestation of the Bangkhunphrom Palace was therefore the result of such movements and it's construction incorparated bricks and concrete wall bearing systems. The Mansard roof with dormers placed evenly was covered with interlocking tiles and supported by a solid wood structure.
The Main Bangkhunphrom Palace 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 19th century. The decorative motifs found in different rooms correspond with each other accentuating stucco designs around window frames and light portholes. The 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 floors.
