Alton Evolution Twelve
The Evolution Twelve by Alton is available from 12ft 9in x 6ft 6in to 12ft 9in x 21ft.
Ideal for really large gardens, estates and nurseries, the Twelve is actually a generous 12ft 9 inches wide and can be built to any length. In addition, you can add one or more internal partitions with double doors which can be used to create different environments within the greenhouse (and they add considerable strength to the greenhouse too.)
The Alton Evolution Twelve includes double doors, a low-level threshold, toughened safety glass, cedar bar capping, aluminium guttering, aluminium base plinth and automatic roof vents as well as louvre side vents.
You can also upgrade to the aluminium bar capping if you want to reduce to almost maintenance free.
