New for 2018, the old Alton Heritage Octagonal has been transformed into a brand new, stunning and contemporary octagonal greenhouse in the same style as the popular Alton Evolution range. With attractive half boarded cedar panels and a lockable hinged door included as standard - the Alton Evolution Octagonal greenhouse has everything the modern gardener requires.
Alton have made a number of improvements to their Octagonal models. Gone is the old timber staging and shelving, and replaced by sleek powder-coated aluminium in a stylish and contemporary 'Moss Green' coloured finish - an optional upgrade. Also, powder coated aluminium guttering, in the same 'Moss Green' colour, has replaced the old PVC gutters. In keeping with the rest of the Evolution range, the Octagonals now come with an integral, powder coated, metal base plinth, and have the option to upgrade from cedar bar capping to powder coated aluminium, making your greenhouse virtually maintenance-free. Some things haven't changed however, as the Octagonal models still maintain the same strong cedar frame, lockable hinged door with low-level threshold, and toughened safety glass throughout.
The Alton Evolution range is crafted within the UK and machined in Alton’s fully equipped workshop using CNC technology. CNC milling gives highly accurate results, all to bring you a flat-packed building that's easy to install. Improved designs include the use of a metal base plinth that helps to keep the wood away from the floor, a new glazing system, low threshold access and a unique gutter design - meaning the Alton Evolution Octagonal is revolutionary in the world of octagonal greenhouses.

Four Reasons Why The Evolution Models Are Even Stronger:
More Wood
Over the years greenhouses made from both aluminium and cedar have become thinner to save costs, after studying the process from raw material through to delivery, the team at Alton discovered that a large part of the costs came from double handling, storage and distribution costs. After streamlining this process Alton have been able to add much thicker glazing bars based on 44 x 44 timbers or 44 x 69 in places giving you a truly robust greenhouse.
A New Bar Capping System
Normally a wooden greenhouse will have its glass held in place with a beading or groove cut into the wood. The result of this can lead to the glass rattling in the frame. The Alton Evolution Victorian bar capping system uses the toughened glass as part of the greenhouse's overall strength by gripping the glass tightly, preventing the glass from rattling and giving a far stronger frame. A cedar bar capping is included as standard on these models, but an aluminium upgrade is also available. The stylish moss colour blends perfectly with the cedar's distinctive silvery colour.
Mortice and Tenon Joints
These cleverly designed joints not only create strength throughout the Evolution's framework, but also make the greenhouse really simple to install.
Toughened Safety Glass
Being 5 -7 times stronger than horticultural glass, the 3mm toughened safety glass (which is fitted as standard) means that every pane is helping to keep the greenhouse structure rigid.

This image shows the high quality construction on the 9ft 2in x 6ft 6in model. Aluminium is used for additional strength and the 'Moss Green' coloured finish matches the rest of the greenhouse perfectly.
Aluminium Base Plinth
Aluminium is rot proof, maintenance free, rigid and easily assembled...that's just 4 reasons why it makes an ideal greenhouse base.
Normally you won't find it used as a base on cedar greenhouses because it doesn't match up with the rest of the building.
The Evolution is a special case; because the components in the areas where the weather or watering takes its toll (the eaves, base, staging, shelving, door support track) are all constructed in aluminium, then powder coated for life with an attractive moss green colour, the base doesn't look out of place. Add to that the convenience of setting the greenhouse up in the first place (rather than trying to lay out concrete blocks for instance) and you'll see why this is so popular.
Lockable Hinged Door
The Alton Evolution Octagonal includes a high quality inward opening hinged door with a mortice lock and key to keep your possessions safe and secure.
