The "Nature Cocoon" project reimagined a compact 960 sq.ft apartment into a serene sanctuary for a German-Asian couple. Our design began by studying their active lifestyle and cultural background to craft a space balancing functionality with restorative tranquility. Early conversations revealed their need for intelligent storage and an extensive book collection, alongside a strong desire to bring natural elements indoors without compromising the apartment's functionality. These became the foundation for our biophilic approach, serve multiple purposes: aesthetic, practical, and ecological.
