Alton Westminster Cedar Greenhouse

Drawing on a hundred years of manufacturing excellence, Alton Cedar Greenhouses has positioned itself at the forefront of quality and inventive garden solutions. Our expertise is evident in the Westminster greenhouse, which brings both practicality and aesthetic charm to your backyard or garden. The Westminster model boasts the same elegant design as our Lancing model but includes a half board cedar bottom for added appeal.

Strong Cedar Framework is Protected from Ground Water

The Westminster Greenhouse is crafted from premium Grade 1 knot-free Western Cedar, ensuring top-notch quality. Each piece is treated with a specialized solution that enhances aging, prevents water absorption, and preserves its natural color. The wood framing, built with mortise-tenon and tongue-groove joints, offers exceptional strength and stability. Solid aluminum gussets reinforce each framing intersection. A unique aluminum foundation profile elevates the wood framing by an inch to protect against water damage. Cedar bar capping secures the glass panels, with an optional aluminum bar capping to slow the aging of the exterior wood while adding to its aesthetic appeal. The delightful cedar scent enriches the gardening experience as the greenhouse ages.

High Strength Glass, Easy to Install Ventilation

The greenhouse, built with 3 mm tempered glass, boasts a steep 45º roof pitch to ensure snow slides off easily, preventing any build-up and potential damage. For added convenience, the doors and windows come pre-assembled. The low-threshold single-panel door swings inward and features a robust handle and key for security. The greenhouse also includes large-pane louvre windows with manual openers and roof vents with automatic temperature-controlled openers for optimal ventilation (see specs below for quantity of roof vents and louvre windows). Every component is meticulously crafted in the UK, reflecting exceptional craftsmanship and attention to detail.

Available Accessories

In addition to a variety of size options, you can personalize your Westminster Greenhouse with 2-slat or 4-slat staging shelves to suit your gardening requirements. For a timeless look, you have the option to add solid cast aluminum cresting.

The Westminster Greenhouse by Alton is a durable and beautiful addition to any backyard, making it an excellent choice for gardeners of all levels. Whether you're just starting out or have years of experience, this greenhouse will meet your needs for an enjoyable gardening experience.
