Petite serre hydroponique — 1/2 acre

Sizing

How the footprint is set

01 · Length

11 bay sections of 4.00 m13 ft 1 in set the length: 44.00 m144 ft 4 in. The bay section — the column spacing along the gutter — is the repeat unit of the structure: one more section adds 4.00 m13 ft 1 in of length.

02 · Width

6 truss spans of 8.00 m26 ft 3 in set the width: 48.00 m157 ft 6 in. That completes the growing footprint: 2,112 m²22,733 sq ft under glass.

03 · Service building

A 24.0 × 16.0 m78 ft 9 in × 52 ft 6 in service building sits alongside the greenhouse — 384 m²4,133 sq ft for packing, technical installations and storage.

04 · The footprint

Overall footprint: 64.00 × 44.00 m210 ft × 144 ft 4 in — 2,496 m²26,867 sq ft covered. Every model in the series is composed the same way: scaling up adds sections and spans, not a redesign.

Discuss this model

A greenhouse is not bought by the square metre. It is bought by the kilo it returns, in the climate it stands in.
