Sizing

How the footprint is set

01 · Length

37 bay sections of 4.50 m14 ft 9 in set the length: 166.50 m546 ft 3 in. The bay section — the column spacing along the gutter — is the repeat unit of the structure: one more section adds 4.50 m14 ft 9 in of length.

02 · Width

12 truss spans of 8.00 m26 ft 3 in set the width: 96.00 m315 ft. That completes the growing footprint: 15,984 m²172,050 sq ft under glass.

03 · Service building

A 81.0 × 24.0 m265 ft 9 in × 78 ft 9 in service building sits alongside the greenhouse — 1,944 m²20,925 sq ft for packing, technical installations and storage.

04 · The footprint

Overall footprint: 120.00 × 166.50 m393 ft 8 in × 546 ft 3 in — 17,928 m²192,975 sq ft covered. Every model in the series is composed the same way: scaling up adds sections and spans, not a redesign.
