The 10x33 Tre 300 is a substantial growing house with space for crops, work areas and group activities. Thirty square metres make it easy to divide the interior into useful zones without losing a comfortable walkway.

The timber frame is part of the appeal here, not something to hide. Pressure treatment helps protect the Swedish pine outdoors.

This size works well for schools, community projects, larger allotments and gardens with ambitious growing plans. Polycarbonate glazing keeps the interior bright while softening harsh direct sun. Its twin-wall construction also slows overnight heat loss.

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.
