Description

Alton Wooden Octagonal Greenhouse, designed for those who want more than just a traditional greenhouse shape. The octagonal design adds a stunning focal point to any garden while maximizing usable space, making it ideal for both gardening and relaxation.

Crafted by Alton Cedar Greenhouses, this model combines the natural beauty of Western Red Cedar, the clarity of toughened glass, and the durability of aluminum to provide a greenhouse that is both elegant and robust.

Distinctive Design

The tall octagonal shape offers a unique aesthetic and a spacious interior, perfect for creating a dynamic and versatile gardening space.

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.
