EggNest, developed by designers Jayoung Kim, Jungmin Park, and Chaewon Lee, is formed from a composite of crushed eggshells and soil, selected for their biodegradability and surface texture. The rough material aids in butterfly landing and clinging, while also promoting the growth of small plants. The structure naturally decomposes over time, returning nutrients to the environment. Its curved form supports thermal regulation, increases insulation, and provides partial protection from predators.
The shelter’s geometry and material strategy are intended to support long-term pollinator activity in the urban fabric. EggNest functions as both habitat and environmental infrastructure, encouraging ecological interaction while blending into the urban landscape. Its design supports stable temperatures, moisture control, and protective conditions for butterflies, contributing to urban biodiversity and cyclical ecological processes.
