Step into the timeless beauty of the 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.

The aluminum base frame prevents direct contact with the ground, minimizing the risk of early rot and extending the greenhouse’s lifespan. Over time, the cedar will age beautifully to a silvery grey, enhancing its natural appeal.

Superior Jointing System: The clever mortice and tenon jointing system simplifies assembly while adding strength to the framework, ensuring a sturdy, long-lasting structure.

Quality Glazing: Equipped with 3mm toughened safety glass, the Alton Cheltenham Wooden Greenhouse offers panes that are 5-7 times stronger than standard horticultural glass. These large panes not only enhance the structure’s rigidity but also shatter into small, rounded pieces if broken, reducing injury risk. The glass fits tightly within the cedar frame, ensuring a secure environment for your plants while providing durability and safety.

Enhanced Insulation & Durability with Bar Capping: The aluminum bar capping system tightly grips the glass, integrating it into the greenhouse’s strength to prevent rattling and create a more stable structure. Rubber seals between the glazing and aluminum improve insulation, while the Moss Grey color complements the cedar as it ages.

The natural insulating properties of cedar help reduce temperature fluctuations, creating a more stable growing environment. Historical studies have shown that wooden greenhouses, like Alton’s, produced heavier crops with less watering and required less heating than aluminum models, showcasing their superior thermal efficiency.

Superior Ventilation

Two roof vents with automatic openers and two large louver vents provide excellent airflow, preventing heat buildup and promoting a healthy environment. The automatic openers use heat expansion to gradually open the vents as temperatures rise, fully adjustable to help you maintain the perfect growing conditions without manual effort, enhancing your gardening experience.

Elegant Accessibility

The lockable double-hinged doors with a low-level threshold and tall eaves provide easy access and ample headroom, combining practicality with refined style.

Sustainable Water Management

The Alton Cheltenham Wooden Greenhouse features an integrated aluminum gutter system with UPVC downpipe for efficient rainwater collection and reuse, promoting sustainable gardening practices.
