The exterior of Doi Tung Royal Villa was built of concrete and decorated with wood slabs cut from discarded teak trees, which came from forest thinning work by the Forest Industry Organization. The interior of the Royal Villa is paneled with recycled pine wood, which came from crates used for imported tools and equipment. The gold teakwood used for flooring was presented to the Princess Mother by the Forest Industry Organization. The simple interior design exudes elegance and functionality, which reflects the nature of the owner of the residence.
The upper floor of the building accommodates four sections. These include the late Princess Mother's private area, a reception hall and kitchen, and the private quarters for the Princess Mother's daughter, Her Royal Highness the late Princess Galyani Vadhana and Thanpuying Tasanavalaya Sornsonggram, Princess Galyani Vadhana's only daughter. The highlight of the Royal Villa is on the ceiling of the main hall. It has hand-crafted wood inlay of the Princess Mother's favourite constellations. Designed by the Astronomy Society of Thailand, light bulbs representing the stars were installed in the centre of the ceiling showing the position of the constellations on October 21, 1900, the day the Princess Mother was born.
The Royal Villa is open every day, from 07.00-17.30 hrs. The entrance fee is Adult 90 baht , Senior 45 baht , Student 45 baht.
