The Spade is a strong, practical greenhouse with excellent headroom, automatic ventilation and a distinctive design that stands out in the garden.

The Spade has straight lower sides that curve smoothly into a raised central ridge, giving it a distinctive shape with excellent headroom and plenty of usable growing space.

The galvanised steel frame is reinforced with internal support bars, helping improve rigidity and overall structural strength.

Automatic roof vents come as standard, helping regulate temperature and improve airflow without constant manual adjustment.

The supplied 30cm ground anchors allow the Spade to be installed directly onto suitable soil or grass in most cases.

A greenhouse should be the place where you worry about whether you planted too many tomatoes — not whether the next storm is going to rearrange your garden.
Its straight lower sides give you useful space close to the edges, while the curved shoulders and raised ridge create excellent headroom through the middle.
That means more room for tall crops, shelving and everyday movement without making the greenhouse unnecessarily wide.
