Dubio from Nelissen is a single brick with shadow joints that creates the illusion of two or three thinly stacked bricks. It has the ability to form creations that were previously impossible with a conventional brick.
The innovative concept offers limitless possibilities: vertical, horizontal, or even wavy shadow joints, everything is possible. You can place this brick vertically, horizontally, or even in irregular bond. Dubio offers the possibility for the architect to use their creativity in a completely new way.
