Price Match Shipping Returns

This greenhouse measures 10'9" wide with a peak height of 11'1", 5'7" high sidewalls, and a steep 45° roof pitch. It’s built from premium Grade 1 Western Red Cedar from Canada — knot-free, dipped, and sealed for long-lasting beauty and durability.

The structure is crafted using strong mortise-and-tenon and tongue-and-groove joints, along with stainless steel hardware. It comes complete with aluminum capping for extra protection against water, built-in shelves, and decorative ridge trim.

The glazing is 3mm thick tempered safety glass. A single hinged door (with a keyed lock) swings inward and is located on one end gable.

Also included:

  • Aluminum base frame to lift the wood off the ground

  • Gutters and downspouts for proper drainage

  • Knee brace spandrels at each rafter joint (ridge and shoulder areas)

  • Extra wooden trusses for added support in extended-length models

Please Note: Individual wood pieces will vary greatly in color (light to dark). 

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.

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.

Guttering Takes the water away and allows you to collect it. Included on every model regardless of which kind of capping you choose. This victorian model has a larger gutter over the standard evolution range
