The Norhage Vegg 300 10x13 is a wall-mounted wooden lean-to greenhouse with room to work.

Twelve square metres run along the wall, enough for staging on one side and a path. The 6mm twin-wall polycarbonate and impregnated pine frame suit year-round growing. Upgrade to 10mm or 16mm polycarbonate if your plot is cold or exposed. The curved plywood arches shed rain and snow away from the wall. Standing height reaches 2650mm at the wall, so you work upright.

The Vegg 300 has no back wall. It mounts against an existing wall, so check yours is sound and can take the weight.

  • 4000mm (13ft 1") Long - Twelve square metres of covered growing.
  • Impregnated Swedish Pine Frame - Pressure treated before it leaves the factory.
  • Solid Plywood Gothic Arches - The curved roof sheds rain and snow off the wall.
  • 6mm Twin-Wall Polycarbonate - Traps a layer of air to hold the heat in.

  • Ridge Height 2650mm (8ft 8") - Full standing room against the wall.
  • Wall-Mounted, No Back Wall - Uses your existing wall as the fourth side.
  • Door 1010mm x 2020mm (3ft 4" x 6ft 8") - Wide enough for a wheelbarrow.
  • Window on the Rear Gable - Opens for airflow and a through-draught with the door.
  • 280 kg/m² Snow Load - Engineered for Nordic winters.
