Nest is an innovative modular system made of recyclable ceramic that is specifically designed to reclaim habitats for birds and insects in sealed or paved areas. The stackable structure combines nesting opportunities with food sources and can be flexibly adapted to the specific requirements of each location. Through this self-sufficient system, valuable connections are created between isolated biotopes, helping to preserve biodiversity in urban environments. Without the need for irrigation or intensive maintenance, “ne(s)t” embodies a true circular product that translates ecological awareness into functional design. Here, the focus is not on human use, but on a forward-looking refuge for our animal co-inhabitants.
