Concealed door hinges in an innovative architecture


The ideal solution for doors

The koblenz concealed hinges represent a highly functional design solution that allows you to create installations of doors that can literally disappear into the wall without breaking its continuity thanks to a perfect flush with the wall and the possibility of customization in the same style as the walls.

Originale complesso residenziale presso Akzen Portu

The building

An impressive cement structure outside the box, composed of numerous levels and volumes, which make up the exterior design of the Azken Portu residence building, designed by the Lekuona Arkitektura studio for the Design House in Basque region. The unique dynamism creates extraordinary transluscent houses full of light. There are no identical apartments in the whole residence complex. A strong sense of space can be perceived inside, underlined by EGO doors without frames by Krona Koblenz, which are integrated and perfectly matched with the white walls of the interior environment.

Indoor space

Every flat inspires purity and linearity. The dominant white hue inside the house gives a sense of colour continuity, brightness, and clearness, enhanced by the doors leading to the various rooms and corridors. Krona Koblenz EGO sliding door systems and concealed hinges Kubica make the doors invisible and appealing inside the wall.
