The wall unit bookcase Gap, designed by Carlo Tamborrini, is an object with a sculptural vocation. It consists of a backdrop, thin shelves and an outer metal frame that generates a strong aesthetic sign that acts as a book-end as well as a light source, thanks to the built-in LED strip that runs through its perimeter. This vertically developed bookcase is a precious and versatile solution thanks to its compact size that spectacularly lights up and furnishes any space in the house. The intensity of the LED light can be adjusted via a smartphone app.
