Bloom: Pavilion Structure: Dimensional precision by imprecise means

Bloom is a small-span vaulted canopy elevated on three columns of differing heights, evolving Heinz Isler's overlooked flower- and steeple-form fabric structures beyond their documented single-apex limitation. Where Isler's frozen fabric experiments produced compression forms with one apex, this research develops multi-apex configurations that, once frozen, invert to create a novel thin-vaulting typology—rigorously tested through a full-scale prototyping in Val-des-Monts, Canada (2025), achieving 2–3mm thickness across a 3m span while withstanding self-weight and wind loading over three days.

Bloom advances this method to its most demanding test: reconciling complex vault geometry with unequal column heights, without calculation or specialist modelling. Drawing on Yona Friedman's "tolerance to imprecision" and Frei Otto's principle of minimal constructional energy, the work demonstrates that generous material tolerances and loose-fit construction can achieve dimensional precision precisely where required - at column interfaces. Built entirely from salvaged materials, Bloom offers both a replicable construction method and a conceptual challenge to computational orthodoxy in structural design.
