Blomstedt designed the massive arcades that form the building's foundation on its ground floor. Vertical stucco and glass wall surfaces travelling upwards from the building's foundation helped the architect to create the impression of skyscraper-like structure. The building was also adorned with impressive external lighting which gave an increasing emphasis to its silhouette after dark.
Following its completion, the building of Liittopankki represented a new type of commercial building modelled after American cityscapes. In Finland, this new international style of building was welcomed as a modern and stylish sight. Writer Olavi Paavolainen even went as far as to praise it as the most modern building in all of Europe. The modern building's picture was used in advertisements and it also ended up in the cover art of writer Erkki Vala's novel Onnelliset pessimistit.
Today, the bank vault is home to a unique and elegant lunch restaurant, ideal for holding both corporate and family parties. One of the conference rooms has been named Marski hall, after Marshal Mannerheim. The hall's wall is adorned by an impressive portrait of Carl Gustav Mannerheim, who also served as the chairman of the Liittopankki supervisory board. The original portrait was painted in the style of national romanticism by the master Akseli Gallen-Kallela and is now located in the banqueting premises of Nordea bank. What makes the painting so special is that it is one of only two known paintings of Mannerheim in civilian clothing. Usually, the marshal's portraits depicted him in uniform. In this painting, Mannerheim is wearing a tailcoat.
