The interior fit-out of a small apartment in Kraków is a project that uses all available spaces. In the central part of the interior there is a large column that houses the building's installations. Our design proposes using this column as an element connecting the living room and the kitchen. The column is finished in the same materials as the furniture in the kitchen and living room. Above the kitchen worktop the column is clad in mirror, which reflects the compact interior. Thanks to this, a potential design problem has become an integrated element of the interior finish. The project also includes a white kitchen, which visually enlarges the room. All interior finish elements were chosen in accordance with the principles of functional and aesthetic design.
