The Struttura Reticolare Acentrata, a Design Strategy for Spatial Organization

Abstract

The Non-centred Reticular Structure is a modular pattern developed by Cesare Leonardi (Modena, Italy, 1935) from 1983, the result of research into spatial and urban planning focusing on trees. It is a model of spatial organization seeking a balance between the spaces of people and those of trees, reconciling and promote all living forms. The Structure consists of a primary pattern of 23 irregular polygons defining the areas belonging to each stakeholder in the spatial organisation: humans, plants, animals. The sides of the polygon constitute a network of nodes (vertices) and connecting rods. The pattern may evolve in space and time, combining biomimicry and geometry, and adapts to different contexts through metamorphosis and deformations. The Structure was applied to ‘Bosco Albergati’ Park (Modena, Italy) which, 30 years after planting, represents an example of spatial organisation imitating nature. This paper presents the Structure as a tool supporting the designer in the spatial organisation of the functional design elements, and investigates its relevance in the design of current green projects.
