The basic principle of the design is not merely reconstruction, but a radical change to the spatial and structural logic of the original building. The compact masonry volume with an almost regular floor plan turns into a more open reinforced concrete frame, whose structure gradually loosens towards the courtyard.

A striking feature are the glass screens of the courtyard façade, which emphasise movement and the inner tension of the space and connect with an organically designed garden on the ground floor. The structure and details deliberately do not pretend continuity, but clearly show the difference between the original building and the new interventions.

The architectural expression of the building gradually lightens the traditional image of a bank as a heavy, closed object. The historic façade gains a new colour scheme, while further inside and towards the courtyard the architecture becomes more open, lighter and more playful.

Colourful and decorative elements appear in the central foyer, contrasting with the technical character of the structure and bringing informality to the space. This approach was summed up by the project's motto at the time: “If it's about money, let it be cheerful!”

The dynamism of the building does not come from formal effects, but directly from working with structure, mass and available construction means. The individual volumes, load-bearing elements and glazed surfaces interpenetrate and together create a space of striking depth and variety.

Technical and structural elements are not concealed, but become part of the architectural expression. The simplicity of the detailing and the clear separation of old and new layers give the building a character that deliberately set it apart from the conventional approach to bank buildings of the time.
