Project Overview

Vegetation Integration

The design preserves and celebrates existing garden elements including plum trees, banana trees, and kiwi plants. The structure wraps organically around vegetation, treating plants as integral architectural features rather than obstacles.

Leaf-Inspired Form

The organic leaf-shaped configuration maximizes shaded area through natural height variations. Two load-bearing edges define the structure: a longer rear edge parallel to the fence and a shorter front edge opening to the garden.

Solar Performance

The south side features lower height for enhanced shading, working in conjunction with the plum tree. The north side rises taller with a more open configuration. The design is optimized for afternoon shade coverage during peak summer months.

Structural System

Hexagonal mesh timber structure with computational optimization provides 40m² of covered area. The column-free interior space remains flexible and adaptable for various uses including dining, lounging, and garden activities.

Technical Approach

Developed using Grasshopper and Karamba3D for structural analysis and optimization. Hexagonal meshing ensures efficient load distribution while maintaining the organic aesthetic required for garden integration.
