The building is known for its architectural beauty which has a strong influence of the French and Indian architecture style. While emerging with the idea of building the palace, Kanwar Bikrama Singh decided to take the help of the French architect. Though the kingdom of Kapurthala was under the threat from British during that time, the king remained firm with his decision to contrast the fort. The exterior of the fort is tinted in pink which clearly shows the French influence in the palace.
The building is registered in the history books as one of the most well designed monument in Punjab and all over India. The architectural style of the building has the fusion of Hindu and French architecture. During its construction, the maharaja of Sikh i.e. Raja Jagjit Singh has took the assistance of the French architect named M. Marcel along with the famous builder of that time Mr. Allah Ditta. This ensured a unique design and texture to the monument. After 80 years of its completion, the beauty of the structure has remained intact.
