Octagonal This 6' x 8'6" octagonal greenhouse, constructed from top grade Western Red Cedar, has a 2'2" wide, key locking , hinged door, one automatic roof vent and two manual side vents as standard. The half boarded cedar fame is mounted on concrete kerbs for extra strength and the greenhouse is glazed throughout with toughened glass. Unusually for an Octagonal greenhouse, these Alton octagonal models include a full set of guttering, draining to a downpipe at the rear. The package includes slatted Cedar staging at the rear and on both sides, with high level hardwood shelving on each side, all supported by strong brown powder coated metal brackets. An optional infill shelf is available for the top rear. With classic good looks, the octagonal shape makes this greenhouse stand out as a garden feature, but this is combined with practicality. The 6'2" eaves height gives an airy feel, while the 'all round' staging provides an ideal work bench and space for displaying plants, with additional discrete storage space underneath screened by the cedar cladding.
