The 'Planthouse Twelve' is the largest standard width of greenhouse in the Planthouse range and measures approximately 11ft 10in in width. Panels can be extended from a minimum of 6 panels (3654mm) to a maximum of 10+ panels.


The cubic air capacity within a Planthouse is greatly increased with the additional height of a low wall, making it a suitable growing environment for hefty plants.

Many gardeners choose to build raised beds for growing cucumbers, melons or tomatoes within this type of greenhouse.


The options are many and varied when you have a garden large enough to accept such a greenhouse. Selecting brickwork for your greenhouse to match that of surrounding buildings will ensure that the greenhouse sits comfortable with the immediate architecture.


The Classic Planthouse collection come with double doors which are located in the curtain wall.


As with all of our greenhouses, the 'Planthouse Twelve' comes with a 12 year structural guarantee, giving you added security in your purchase.
