Hidden doors

An invisible door can be a solid surface finished with the same shade of paint, wallpaper pattern or other material as the wall. A door with a concealed frame will be perfectly flush, the only hint of its whereabouts will be a discreet handle and the slight outline of the door line. The concept in which doors are “sunk” into the wall is one of the most fashionable trends in interior design. Doors hidden in the wall, concealed doors painted with wall paint, invisible doors covered with wallpaper are perfectly flush with the wall, thus creating a harmonious effect in the interior. This solution makes the space more minimalist. PIU Design is a manufacturer of aluminium frames (hidden frames) and door leaves.
