BIT Creative Barnaba Grzelecki designed natural colors throughout the Signal Iduna office in Warsaw, Poland. Signal Iduna is one of the biggest financial-insurance institutions on German market and has been providing services to the both private and corporate clients since over one hundred years. The arrangement occupies the area of about 1500 square metres and is located on two floors in Wola Retro office building in Warsaw- the whole 12th floor and the part of the 10th floor. The Interior is very light and pleasing to the eyes. Some colder accents such as grey and concrete are diversified by a big amount of wooden and natural green elements. The space is well lightened and well communicated that was mainly possible due to the appropriate depth of the building route. The conference rooms are named by the cities where the Signal Iduna’s departments are located. The details such as names and skylines of the cities on the wall finishing are the main motive in this space giving the final tone to the interior. In my perspective the most valuable element of this office is the kitchen located in the central part of the office, in addition accessible from two sides of the area.
