Western red cedar

We select only the best Western Red Cedar, supplied from renewable sources as it's the ideal material for use in our greenhouses. Noted for its extraordinary durability, it doesn’t shrink, swell or warp excessively, and readily holds wood stains and micro-porous paints. It has prime insulating qualities and its pleasant aroma is naturally repellent to moths, insects and vermin.

finest-materialsAll of our unpainted greenhouses are factory-treated by total immersion in our Golden Honey cedar preservative prior to delivery which renders it virtually immune to decay, while our painted greenhouse options look stylish in any outdoor setting and are protected with micro porous paint.

If you wish to maintain the original warm, golden honey colour, we recommend you re-treat your frame annually. If not, the wood will gradually fade to its attractive natural appearance - varying from almost pure white of the narrow sapwood to the light straw shade of the heartwood. This will not affect your 10 year framework guarantee.

Other features and options


Mortice and tenon joints.The Cleverly designed jointing system on the Evolution has the duel benefit of making assembly straight forward and adding strength to the framework.

Aluminium base - This keeps the wood well away from the base where water can sit. Plus this unique design feature allows the glass to sit directly onto the metal base - which means that the side water is not running onto the wood, (which is a 'rot-spot' on other greenhouses) The Metal base is included on every Evolution model, regardless of which kind of capping you choose.

Guttering Takes the water away and allows you to collect it. Included on every model regardless of which kind of capping you choose.

Roof vents. A generous allocation of roof vents is included with every model and every roof vent has an automatic opener included as standard. These clever devices work through heat expansion alone to open your roof vents gradually as the temperature changes. Fully adjustable, they help you to create the perfect growing environment.

Louvres Your new Alton Evolution model will also include one or more louvre windows. These work in tandem with your roof vents - as the automatic roof vents open and release the warm air, the greenhouse effectively sucks air in through the louvres. These can be positioned near the bottom or the top and on most models at the side of the greenhouse or at the rear. Supplied as manual opening as standard and you can add automatic louvre openers if you wish.

The unique Alton Evolution door system includes the low-profile door threshold. This popular feature means that you have no step at the door (many other greenhouses have a step at the door). Models of 8' wide and above have 4' wide access double doors which allow easy entrance for a wheelbarrow or wheelch

Upgrade option Aluminium bar capping - With this new Aluminium bar capping system you really can have a virtually maintenance free Cedar greenhouse - and the stylish moss colour blends in perfectly with the cedar as it ages to the distinctive silvery colour.

The eaves height of 5'7" on the Alton Evolution models is excellent and is as much as 18" higher than the lowest greenhouses on the market. The extra height gives you several advantages: There is more air in the greenhouse creating a better growing environment, you have more head room and a higher door, and you have plenty of room for a high level shelf in the greenhouse.

The Alton Evolution 6'6" greenhouse

Evo Six

The most popular size of all in the greenhouse world is a 6x8 model and this 6’6” wide range gives you  a generous extra few inches which make all the difference to this highly practical greenhouse.

When you walk into this Alton Evolution model the first thing that you will notice is the wonderful smell of the Western Red Cedar. It’s this pleasant aroma that pests don’t like and one of the reasons that Cedar is so famous for greenhouse making.

Like all the Alton Evolution models, the Six is packed with practical features that improve the lifespan of the greenhouse – for example all the Roof panes overlap the timber slightly, and the metal base keeps the timber off the damp ground, thus eliminating by design two of the old trouble spots where water would eventually cause the Cedar to rot.

Plus if you choose to upgrade form the standard Cedar Capping to the Aluminium capping then your greenhouse will be almost maintenance free. The Capping system is a strong aluminium capping system which screws into the Cedar frame and clamps the glass into the framework tightly – meaning that very little Cedarwood is actually exposed to the elements. The Moss powdercoated finish blends in perfectly, particularly after the Cedarwood has weathered in to  its natural silvery colour.

Automatic roof vents are included as standard and these release warm air out of the top of the greenhouse whist cooler fresh air is sucked in through the louvre side vents – This gives you the perfect ventilation.
