Twin City Tower, Bratislava

Client: Competition for HB Reavis

JRA produced the winning design in a competition for the new facade of Twin City South, Bratislava for international client HB Reavis. The project is due for completion in 2017.

The existing building comprises the A1 tower and a large horizontal base, set on the site of the KABLO power cable factory at the junction of Karadzic, Mlynske Nivy and Grosslingova Street. JRA took inspiration from the history of the site and the roof-scape of the area to design cladding panels featuring a non-uniform pattern created by different colours and arrangements of ceramic frit on sheets of glass. A natural ventilation system will be incorporated into the panels using a system of baffle plates which direct air from the edge of the panels into the cavity and into the office spaces when operated by the occupants. The resultant facade will produce depth and reflectivity in different lights and times of day. The cladding for the A1 tower was designed to enhance the verticality of the 24 storey office building, whilst the seven storey base uses a similar set of panels in a different design vocabulary to distinguish the distinct elements of the building.
