Classic 'Twelve'


The largest of our Classic range widths, 'Twelve' cedar greenhouse measures at approximately twelve foot by twelve foot length as standard. To make the very most of your growing space, the generous width of this greenhouse allows for a side of staging at either side of the structure, as well as infill staging along the plain end if you wish.

Approximately 11ft 10in in width. Panels can be extended from a minimum of 4 panels (2458mm) to a maximum of 10+ panels.

The modular design, coupled with a wide range of base options, make it easy to order a greenhouse to your individual requirements;

  • Single Course of brickwork - Our recommended option for a glass-to-ground greenhouse, a single course of brickwork along the perimeter of your structure slightly elevates the footings, allowing for better water drainage in wet conditions.
  • Cedar Boarding - Our greenhouses are designed to easily swap out a glass pane for a cedar board or louvre vent. Give your greenhouse a more luxurious feel with a cedar base.

Our Classic and RHS collection also comes with our unique full ridge automatic ventilation as well as stainless steel and solid brass fixture and fittings as standard.
