Our Planthouse range is of a similar design to the Classic greenhouse range, however it is built to be housed on a low wall, offering an elevated eaves height of around 7 foot.


Panels can be extended from a minimum of 6 to a maximum of 10.The greater cubic capacity created within the Planthouse, together with the insulation created by the brick base ensures that the air temperature within this greenhouse is at its most even avoiding the wider (and wilder) fluctuations of smaller and metal structures.​​​​​​​
