This compact Tre 300 gives keen gardeners a generous growing area without taking over the whole plot. There is room for beds along both sides, plus a clear central path for easy access.

Pressure-treated Swedish pine gives this greenhouse warmth and character. The solid curved arches create its graceful roof and dependable strength.

So, if it is going onto an allotment, into a school or onto an exposed plot, this model makes sense. The unbreakable twin-wall polycarbonate panels diffuse strong sunlight and remove the worry of broken glass. They also help retain useful warmth.

The opening rear window works with the door to move fresh air through the greenhouse. Optional roof vents and automatic openers make summer temperature control even easier.
