The first floor is the beginning of the B39 tour and there are convenience facilities for visitors here. It is a space that has been transformed to contain technology, people, culture and art by reconstructing the landscape of facilities where garbage was burned and disposed of in the past and the people who handled it. It consists of the Multimedia Hall, Bunker, Air Gallery, Ash Bunker, and Air Emission Control Room.

The bunker, which served as a garbage storage tank in the past, is the most symbolic space of Bucheon Art Bunker B39 and the space that became the motif of the name ‘B39’. It is surrounded by a 39-meter-high concrete wall from the underground space and is currently being used as a place for various creative exhibitions, performances, and shooting sessions that actively utilize the volume of the space.

This is a space where the incinerator burned garbage in the past and is now an outdoor space with harmonized marble tiles and concrete structures. It was designed a multi-purpose outdoor space based on the motif of a ‘courtyard’, a concept commonly used in house design, and it can be viewed from various angles and heights while bringing in the light and clear sky from the outside as all walls have been removed.

In the past, the second floor was a space for employees to operate the garbage incinerator, such as the employee's night-duty room and the central control room. Currently, there are offices for the executives and employees who are in charge of the operation and management of Bucheon Art Bunker B39, as well as a studio for education and rental. The central control room and the ash bunker/crane cockpit maintain their original incinirator appearance and are utilized as a kind of experience museum.

The Ash Bunker is located next to the Air Gallery, where the ash from waste burned in the incinerator was collected in one place. The crane installed at the top of the Ash Bunker was used to pick up ashes, and visitors can see the Ash Bunker through the glass window inside the 2nd floor.
The crane cockpit located on the 2nd floor was a space used to control the crane at the top of the Ash Bunker, and it was used to pick up ashes and take them out to the landfill. Although it is currently out of operation, the control mechanism has been preserved and made available for viewing, and the long road leading to the Crane Control Room is used as an exhibition space to present works of various genres.

It is a space where there was electrical equipment such as electricity facilities of the incinerator, substation and distribution facilities that managed the transformation and distribution of electricity in incinerators, etc. All devices have been removed and it has been turned into a dark room, and the context of the electrical appliances and electricity that filled the space now allows for various artistic transformer activities such as digital art performances, projection mapping, and media art exhibition.
