The decisive factor for the urban planning concept was primarily the spatial-architectural ensemble of the Carmelite monastery and the Carmelite church with St Anne’s Chapel. The existing layout prohibits extensive overbuilding and for this reason provokes the designation of the storerooms and restoration workshops on the ground and basement floors. Despite this premise, however, a particular problem was posed by the architectural emphasis on the beautiful Carmelite Church with St Anne’s Chapel, which had been largely preserved and was to be restored. The choir of this building prohibits its structural constriction.

The extensive formulation of this concept aims to create an introverted overall complex. The exhibition areas are thus opened up to the north with a view of the Carmelite Church and Carmelite Monastery and at the same time face the simply designed courtyard areas between the new museum buildings and the monastery area, which are landscaped with lawns. These openings, which are emphasised to the north, make sun protection largely unnecessary and refer to the play of light and shadow of the old buildings. Opposite the Alte Mainzer Gasse, on the other hand, the character of a closed complex is emphasised in that the wall surfaces here only have functional openings.
