Istana Negara (State Palace) is an Indonesian Presidential Palace located in the Central Government Core Area (KIPP) of Nusantara. It was officially inaugurated by President Joko Widodo on 11 October 2024.
The palace is situated in the lower or southeastern section of the Istana Garuda complex, a layout mirroring the relationship between the Istana Negara and the Istana Merdeka in Jakarta. The complex is built on a 100-hectare (1,000,000 m<sup>2</sup>) site; 50 hectares are dedicated to the palace grounds (including Istana Garuda), while the remaining 50 hectares consist of a botanical garden.
Designed under the "smart forest city" concept, the landscaping features 40% endemic plants and 60% non-endemic species from Kalimantan. The grounds include 2,509 trees from 35 different species, 82,948 shrubs across 24 species, and Zoysia matrella grass for the flag ceremony field. Architectural details include flamed granite and andesite stone, granite planter boxes, textured paint, and various water features.
The Istana Negara was designed with a prominent monumental and symmetrical appearance. Its facade features 34 tall pillars finished with White Thassos marble. The windows are equipped with sun energy glass, clear glass, and bulletproof glass. The structure's walls consist of 20 cm thick concrete layered with high-craftsmanship wood carvings by artists from Java and Bali. Other wall sections are finished with woven banana fiber, porcelain tiles, marble, granite, and labradorite.
The building contains 11 primary rooms, each featuring interior concepts centered around Indonesian cultural themes:
