The Jal Mahal palace is an architectural showcase of the Rajput style of architecture (common in Rajasthan) on a grand scale. The building has a picturesque view of Man Sagar Lake, but owing to its seclusion from land is equally the focus of a viewpoint from the Man Sagar Dam on the eastern side of the lake in front of the backdrop of the surrounding Nahargarh (“tiger-abode”) hills. The palace, built in red sandstone, is a five-storied building, of which four floors remain underwater when the lake is full and the top floor is exposed. One rectangular Chhatri on the roof is of the Bengal type. The chhatris on the four corners are octagonal. The palace had suffered subsidence in the past and also partial seepage (plaster work and wall damage equivalent to rising damp) because of water logging, which have been repaired under a restoration project of the Government of Rajasthan.

The structure was built in 1799 by the Maharaja Sawai Pratap Singh, grandson of Maharaja Sawai Jai Singh, the founder of the city of Jaipur, India. He was so inspired by the unique structure of Khetri Mahal that he built this grand and historical palace.

It was designed by Lal Chand Ustad. Its five-floor exterior is akin to a honeycomb with its 953 small windows called Jharokhas decorated with intricate latticework.^[2] The original intent of the lattice design was to allow royal ladies to observe everyday life and festivals celebrated in the street below without being seen, since they had to obey the strict rules of “purdah”, which forbade them to appear in public without face coverings. This architectural feature also allowed cool air from the Venturi effect to pass through, thus making the whole area more pleasant during the high temperatures in summer. Many people see the Hawa Mahal from the street view and think it is the front of the palace, but it is the back.
