Nestekerros

Nestekerros is a term used in speculative ecology and vernacular architecture to describe a modular, multiunit nesting system in which individual modules form a cohesive, spatially integrated structure. The concept emphasizes communal living, resource sharing, and collective defense, and it is applied across a range of theoretical contexts to describe how complex nests or settlements can grow through small, repeatable building units.

In its typical morphology, a nestekerros comprises discrete modules or cells arranged around shared central spaces such as courtyards or corridors. Modules are constructed from locally available materials and are linked by connectors or walkways that allow movement between units. Variants may organize modules in rings, clusters, or stacked tiers, enabling scalable expansion without altering the core organizational principles.

Ecology and behavior within nestekerros systems stress cooperation and information exchange. Colonies coordinate assembly through simple local interactions, balance labor and resource exchange, and adapt to changing conditions by adding or removing modules. The design can offer advantages in thermal regulation, predator deterrence, and resilience to disturbance, while also presenting challenges related to privacy, governance, and collective decision-making.

History and scholarly reception of nestekerros trace to interdisciplinary studies in the late 20th and early 21st centuries, drawing on ethnography, architecture, and ecology. Some researchers view the term as a useful umbrella for a family of related nesting patterns, while others caution that it risks conflating distinct systems across species and cultures. The concept remains a topic of discussion in theoretical discussions of cooperative design and social organization.
