Perceptural Architecture – a concept introduced to the field of architecture for the first time by Bogusław Barnaś – defines the stylistic character of the designed extension of Krakowska Kamienica.
Perceptual Architecture describes a variable architectural style dependent on perspective, that is, on the viewer’s position in relation to the building. From a distant viewpoint, the human eye perceives the extension as distinctly Gothic, with slender, soaring lines; from a closer perspective, it appears as Renaissance arcades; and in immediate proximity, it takes on Baroque forms. Depending on the point of view, the extension may be perceived as an additional storey, a Baroque cornice, or even a dome-like form. In this particular case, the extension seen from Dębnicki Bridge takes on a Gothic character, from the Vistula Boulevards it resembles Renaissance arcades, while from Powiśle Street it transitions into soft, flowing shapes – reminiscences of Baroque ornamentation.
