With a spacious depth, the Gabriel Ash 6ft x 12ft classic greenhouse offers a growing area any gardener would be proud of, suited for a large variety of flowers, fruit, vegs and herbs.

Expertly crafted from western red cedar and aluminium, this greenhouse is handmade to order in Cheltenham, mixing modern and traditional materials in order to make the most of both aspects; traditional design with the use of wood, strength and practicality from the use of metal.

The main frame of the greenhouse uses cedar, benefitting from the naturally occurring oils within the grain which helps to protect it from rot and weathering. Whilst discreetly integrated internally, you'll find a powder-coated aluminium A-frame support, as well as a metal roof ridge and roof glazing bar capping, which reinforce the structure to create a highly stable, exceptionally standing growing space. The addition of metal supports, notable to Gabriel Ash ensures that your new greenhouse is able to stand up to the harshest of UK weather, and overall, has been to designed to last.

There's no need for roof windows with this range, as by standard it comes with a unique roof ridge ventilation system, able to automatically open and close itself as the weather outside changes, offering autonomous airflow for your growing plants inside. Additionally, you'll find four manually opening side windows, metal guttering and downpipes and toughened glazing with capping throughout.

Buy this Gabriel Ash classic 6ft x 12ft greenhouse and it'll be expertly handmade in Cheltenham, England, with free delivery throughout mainland UK once crafted.
