The collections are divided in a main room that faces the park and three levels of more intimate and quiet spaces on the east side. These spaces are extremely flexible, to permit multiple possible internal layouts. The learning and doing area is accessed from bridges that cross the atrium at all levels. The children’s world on the third floor can be accessed directly by the elevators, or can be entered through the stepping bookshelves children’s sector that faces the park. The top floor is dedicated to the staff offices and to the public sauna, from where the green rooftop can be accessed. There is one basement level that houses the main event spaces on the West side. They share a foyer that is intended to connect to the future underground multipurpose space under Makasiinipuisto park. On the west side of the basement, the loading area and the technical and logistics area are located. A ramp descends from the North-East end of the site. The ramp is open on the street side, allowing views through it from the street to the exhibition hall.
