The Law of the Indonesia Republic Number 5 Year 2017 about the Advancement of Culture, opens the appreciation of art as a work of civilization. So far, the forum for giving appreciation to the arts and culture has been accommodated by the National Gallery of Indonesia, in Indonesia we call Galeri Nasional Indonesia or GNI. GNI is a reputable art gallery owned by the State as a venue for exhibitions and art events on a national and international scale. Unfortunately, the existence of GNI has limited area and limited space which is unable to accommodate such great interest for the public in appreciating art. This study is about an idea to provide a solution for the availability of showrooms to respond to the interest of artists exhibiting beside held on GNI. Referring to the Adaptive-Reuse theory in the case of the National Gallery and also the conditions related to the Covid-19 pandemic, a study is located in The Ex Kemayoran Airport Building. That building is decided to be a new showroom as the GNI satellite. The Ex Kemayoran Airport Building whose condition is currently not maintained, through the Directorate of Arts, Directorate General of Culture, Ministry of Education and Culture is planned to be used as a national cultural heritage building. The output of this research is in the form of recommendations regarding the layout of the showroom. It is hoped that these recommendations can be used as references that can be offered to make The Ex Kemayoran Airport Building a "satellite" from the National Gallery of Indonesia. The recommendations also proposed to accommodate post-Covid-19 health protocols.
