The architecture of the palace has a mix of traditional Lao motifs and French Beaux-Arts styles.

Above the entrance is a three-headed elephant sheltered by the sacred white parasol, the symbol of the Lao monarchy.

On the right of the entrance is the king's reception room, where busts of the Luang Phrabang and later, Lao monarchs are displayed along with two large gilded and lacquered Ramayana screens, crafted by local artisan Thit Tanh.

The walls are covered with murals that depict scenes from traditional Lao lifestyles, painted in 1930 by French artist Alix de Fauntereau.

The room includes another Buddha, engraved with large elephant tusks, and three beautiful saew mâi khán (embroidered silk screens with religious imagery) that were crafted by the queen.

On the left of the entrance hall, the secretary's reception room is filled with paintings, silver, and china that have been presented to Laos as diplomatic gifts from Myanmar, Cambodia, Thailand, Poland, Hungary, Russia, Japan, Vietnam, China, Nepal, the United States, Canada, and Australia.
