The existing building, which is almost entirely underground, was partly demolished and partly reconstructed. The part of the building near Bulínova street has been newly extended by four above-ground floors and will complete the street line in the future. The superstructure consists of a monoblock softened by the division of windows and one large gate on the north and south sides with a facade made of cor-ten sheet. The eastern facade is in dark gray color due to the possibility of a future extentsion.

The main entrances are oriented from Bulínova street. They are located on the east and west sides of the building. The western one serves for the Moravian Gallery and the eastern one for the Moravian Library. Another possible acces is an underground corridor, which is connected to the Moravian Library building. In the building there are the depository of the Moravian Library, the depository of the Moravian Gallery with a research room for the public and all the necessary facilities.

The design of the building was based on the principles of the circular economy. Most of the existing building was retained and renovated. Only the statically unsuitable section was removed. The new building has been designed to allow for future disassembly and sorting into individual materials.

The structural system of the existing and new part of the building consists of a reinforced concrete monolithic structure. The perimeter walls are covered with a ventilated façade made of cor-ten sheet with mineral wool insulation. On the part of the facade in the place of the planned extension there is an ETICS insulation system with anthracite-coloured plaster. The roof at ground level is used for parking. On the new part of the building there is a retention roof with extensive greenery.

The technical equipment of the building is designed to allow safe storage of the library collection. The windows are fitted with front window blinds and UV film.
