A unique project for mobile offices - StepBoxes - developed for a young Cracow brand. StepBoxes constitute a workplace for the brand promoters but they function primarly as a meeting place with the Stepcloser card holders. The yellow colour on the outside symbolizes happy emotions accompanying the membership of the discount programme and the mirrors used inside reflect and multiply the benefits of the card holders. StepBoxes are steel structure cuboids of 316 x 622 cm and 300 cm high. The construction is lined with yellow HPL plates. As glazing grey aluminium joinery was used. The weight of each mobile office is about 6 tonne. The interior lighting is provided by lamp panels with a barrisol layer which diffuses LED light imitating natural light. Outside module system terraces were installed. Above the entry to each StepBox openwork constructions were placed which serve simultaneously as a roof and a sun shield. The entire construction is mobile and functions as a temporary object.
