RAINDROP is presented as a system that reuses rainwater in everyday urban life. Designed for small households, it collects rainwater through a hanging umbrella and redirects it to support plant care. The concept highlights rainwater as a clean, natural resource that is often overlooked. By integrating this process into daily routines, a simple ritual of collecting and watering is created. The project also includes seed packages inspired by brick structures, encouraging indoor planting. RAINDROP promotes a practical way to reconnect with natural cycles while reducing waste.
