An office building in the centre of the capital city on Chmielna Street, built between 1993 and 1996 as the Aktyn Business Centre. Designed by Miljenko Dumenčić and Krzysztof Kamiński in a postmodernist style. Saved from demolition and renovated between 2020 and 2022 by Syrena Real Estate. The modernisation of the building, designed by interior designer Anna Łoskiewicz (Łoskiewicz Studio), gave it a new, even more postmodernist look, referring to the Memphis style and retro elements. Changes were made to the façade, which now features distinctive geometric patterns, the entrance, the interiors and the square in front of the building. The office building was renamed HOP (English: hops) and became an example of the successful modernisation of a 1990s building, not by erasing, but by emphasising and developing its postmodern style. Address: 132/134 Chmielna Street, Warsaw.

The Memphis style was created in the early 1980s in Milan on the initiative of Ettore Sottsass and was a reaction against minimalism, functionalism and the principles of so-called ‘good taste’ in design. It proposed a distinctive and provocative aesthetic with bright colours and geometric forms inspired by art deco, pop art, Disney cartoons and American kitsch of the 1950s.
