This project is a study on timber-based plate-shell domes with a set base diameter and a variety of topologies using different combinations of perforation ratios. Using a combination of geometry generation and performance optimization, parameters of folds, depth of folds, height of dome and the effect of perforations on structural efficiency, interior lighting and acoustics are explored. The combination of a visual database with both structural and architectural oriented performance parameters, gives the designer added insight in overall form determination. The overall geometry and its tessellation are also discussed in terms of environmental performance.
