Description

Alton Cheltenham Wooden Greenhouse – a classic design that exudes both charm and functionality. With its simple yet elegant structure, the Cheltenham invites you to create your own garden retreat, where the warmth of Western Red Cedar and the clarity of toughened glass come together to form the perfect growing environment.

Imagine yourself surrounded by lush greenery, the sun streaming through the crystal-clear glass panes, and the comforting scent of cedar filling the air. Whether you’re nurturing delicate seedlings or simply enjoying the peace of your garden, the Alton Cheltenham offers a serene space to cultivate both plants and relaxation.

Classic Greenhouse Design

The Alton Cheltenham Wooden Greenhouse embraces a timeless design, with its half-paneled wood and glass construction that blends seamlessly into any garden setting. Its clean, simple lines evoke a sense of tradition, while the steep roof pitch not only adds to its classic aesthetic but also serves a practical purpose – allowing snow to easily slide off, making it perfect for snowy climates. The tall, airy structure maximizes space and light, making it ideal for both novice and experienced gardeners alike.

Durable Construction

Constructed with 100% Western Red Cedar and an aluminum base frame, this greenhouse is built to endure. Western Red Cedar is an ideal material for greenhouses because it absorbs moisture without warping and dries quickly, maintaining its structural integrity. The wood is naturally resistant to rot due to its high content of preservative oils, which also emit a pleasant aroma that deters insects and pests.

Additionally, the use of thick glazing timber bars (44x44mm and 44x69mm) provides exceptional strength and stability, unlike many modern greenhouses that have reduced thickness to cut costs.

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.

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.

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
