In 1937-1938, construction of the Social Security Building in Vilnius was underway on the basis of the winning competition design by two Warsaw architects, Stanisław Murczyński (1906-1974) and Jerzy Sołtan (1913-2005). One of the largest buildings in the city between the wars, it stood on the representative Mickiewicza Street (now Gediminas Avenue), at the junction with Dąbrowskiego Street (now Jakštasa Street), a short distance from the banking facilities built at the time.

The Insurance Company building, laid out on an L-shaped plan, consists of a main part planned on Mickiewicza Street and a side wing on Dąbrowskiego Street. The dominant, five-storey body of the main part was solved in the monumental convention with the use of elements typical of the functionalist trend, among others, the principles defined by Le Corbusier. The ground floor area was clearly demarcated with rustic granite cladding. On the other hand, the part facing Dąbrowskiego Street, which housed the entrance area, was heavily undercut and supported on pillars. The façade on this side serves as the façade and was therefore designed in the most expressive manner: the narrower left side is clad with smooth stone slabs, while the right side is of a skeleton construction with window openings. The two parts of the façade are juxtaposed in a contrasting manner. In this way, the idea of creating visual effects with different materials and textures, which was important for modernist architecture, was realised.
