The architect Karel Pecánek chose a reserved modern style for this building. The gable roof is an adaptation to the surroundings of the historic market square. The large windows on the ground floor illuminate the large and well-equipped counter space. Some of the windows on the first and second floors have different sizes and formats. Disrupting the house's symmetry is also achieved by lowering the roof line on the left side. Further the hip roof above the main area of the bank in front of the gable roof. All those features create a moving, even a bit turbulente architecture.
A plaque commemorating the construction of the bank in the foyer is set in a mosaic. This shows two figures. The left figure symbolizes diligence (pracovitost), the right thrift (spořivost). Between those two symbols is shown the double-tailed lion, the heraldic animal of Bohemia. Red-white-blue ribbons symbolize the Czechoslovak state. Fruits, specifically pears and apples, mark the success for bank customers and their trust in this bank.
