All prices shown include VAT and deliveryThe Alton Evolution SIX-LT lean-to greenhouse is a stunning 6ft 5in deep lean-to greenhouse available in a wide range of lengths. The cedar construction means this lean-to greenhouse can blend into any garden style, whether you have a traditional cottage garden or a modern and contemporary garden - the Alton Evolution Six Lean-To is perfect for your home.
You can position your sliding door on either end when assembling and this model is a part of the Alton Evolution range so it includes all of the standard features of benefits that have made Evolution models so popular – combining the beauty of wood with the modern practicality of powder coated aluminium. Toughened glass comes as standard as well as good ventilation (louvre side vents plus automatic roof vents), aluminium base (so no cedar touching the floor), guttering and downpipes as well as superb optional staging and shelving.
This model comes with cedar capping as standard, however you can choose to upgrade to the maintenance free aluminium capping system which is powder coated in the elegant 'Moss Green' coloured finish.
Western Red Cedar
Western Red Cedar is famed for its extraordinary durability and resistance to decay. It has a pleasing aromatic odour and is treated with a natural preservative oil which protects against the elements.
Cedar Bar Capping
As standard your greenhouse comes with cedar bar capping which holds in the glass firmer and stronger than other greenhouses.
Toughened Safety Glass
3mm toughened safety glass is supplied as standard for strength and safety.
Guttering and Downpipes Included
Attractive aluminium guttering and downpipes allow you to collect water while protecting the cedar framework.
Metal Base
The metal base keeps the wood away from the floor and enables the glass to overlap the wooden frame so no water sits on the cedar.
Louvre Side Vents
Included is a slatted ‘Louvre’ side vent which allows extra air flow into your greenhouse and really makes your plants flourish.
Automatic Opening Roof Vents
Included as standard, these roof vents open automatically as the greenhouse warms up – keeping your plants from overheating.
High Eaves (5ft 7in)
Extra high eaves gives you plenty of headroom and room for a high level shelf.
10 years Framework Guarantee
Your Alton greenhouse comes with a free 10-year frame guarantee.
Moss green Aluminium Bar Capping
Upgrade to Aluminium bar capping for a virtually maintenance free cedar greenhouse – and the stylish moss colour blends perfectly.
Staging and Shelving
Add 25” staging and 12” shelving for a practical and stylish upgrade. Available in a moss green Aluminium finish.
Hanging Basket Brackets
Use these brackets to hang baskets, without the need for an obtrusive rail.
Internal Blinds
Add blinds to your greenhouse to create shade for your plants.
Automatic Louvre Openers
Automatic openers can be fitted to the louvre vents, just set and forget!
Extra Roof Vents
An additional roof vent increases the flow of air through your Alton greenhouse, ideal for orchid houses or other specialist environments.

The Alton Evolution SIX-LT is has a standard width of 6'6 ( 1.68m )
It's an ideal size for most domestic gardens but doesn't compromise on height with the eaves being at 5'7in for more space. There's a choice of lengths from 4'5 ( 1.35m ) up to 12'9 ( 3.87m ).
Toughened safety glass and screw-in cedar bar capping are standard which ensures the glass stays where it's put ! The gutter, door support and base are long life aluminium construction which are then powder coated in an attractive moss green finish.
The framework carries a ten year timber guarantee.
This is an extended version of the Alton Evolution lean-to. Although not shown in the catalogue, the building can be extended on request.
Optional green aluminium capping, and short lengths of staging and shelving are fitted to this model.
The Alton Evolution Guttering is an attractive moss green finish aluminium extrusion and is supplied with a downpipe for each side of the greenhouse.
The external capping over the glazing is showing the optional green aluminium bar capping which is totally maintenance free ( except for a bit of a wash down every now and again ).
In particular please note how the toughened safety glass extends beyond the cedar eaves bar, discharging water directly into the gutters rather than allowing it to run across the cedar itself.
This picture shows the standard external cedar bar capping which is supplied with each Evolution unless you opt for the green aluminium bar capping. It is screwed in place and holds the glass firmly and securely.
Alton Evolution Aluminium Staging widths vary according to the model you choose :
Evolution Five : 20" wide 3 slat staging, 12" wide 2 slat shelf
Evolution Six, Eight, Ten and Twelve : 25" wide 4 slat staging, 12" wide 2 slat shelf
It's maintenance free and blends beautifully with the cedar framework.
Alton Evolution staging and shelving is finished in moss green powder coated finish and just needs a wipe down to keep it clean and tidy. The cantilever brackets leave room beneath the staging for storage rather than having staging legs in the way.
The Evolution has been developed in the UK in our fully equipped workshop with the latest technology. We have to confess though that one or two of the machines have been reliably making other Alton Greenhouses for over 40 years !
The jointing system is incredibly strong and makes the Evolution rock solid once assembled... so it will cope with almost anything the British weather cares to throw at it !
Constructed in long -life cedar sections these greenhouses do not compromise by using thinner glazing bars; they are machined from 44mm x 44mm cedar (and 44mm x 69mm sections in places )
These are the reason behind the superior strength of the Evolution.
You would expect any timber greenhouse to be built this way but in fact many others simply butt joint and nail the components together.
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.
A downpipe is provided for each side. There's a 45 degree bend suppied too, either to discharge water at ground level or to create a joint higher up the pipe to divert water to a barrel.
A single door is standard with the Evolution Five and Six. The Eight, Ten and Twelve have double doors. All sizes have the low threshold shown in the picture.
This makes it easy to wheel a barrow in and out or provide access for wheelchairs and pushchairs.
The single door access width is 560mm ( 22" )
This example of Alton's internal roof blinds shows the degree of shading achieved to good effect.
The blinds retract on a sprung top rail.
