I am driven by a deep desire to create spaces that touch people the moment they step inside — spaces that spark a sense of joy, lightness, and belonging. Places where even the simplest everyday moments feel special, where a quiet sense of comfort and calm can unfold naturally.

After decades of working as a designer I felt a growing need to move beyond products and shape entire atmospheres. Starting in the late 90´s with children rooms, I founded add it interior architecture as a way to bring this vision to life — to design spaces that are not only seen, but truly felt.
