Constructed in 1927 by the civil engineer V. Patek, the original "Telephone Exchange" building at Number 5 Bakuniskaya Street is a classic example of Russian industrial constructivism. During the complete restoration of the site, the main historic façade, has been restored to its original aesthetic. A new independent volume, with a striking, triangular cantilevered façade, now hovers above the existing historic building. The contrast between old and new is emphasized through the employment of materials: the new facade is a dramatic contemporary form, which contrasts the original grey stucco.
