Westminster Cedar Greenhouse
Overview
The Alton Westminster cedar greenhouse from Britain combines natural beauty with expert craftsmanship. Drawing on over a century of greenhouse expertise, Alton designed the Westminster to combine elegance with long-lasting performance. Built from Grade A knot-free Western Red Cedar, each piece is treated to resist aging, moisture, and rotting. Strong mortise-and-tenon joints and a raised aluminum frame protect it from ground moisture and ensure exceptional stability. Aluminum bar capping secures each glass pane, extending the structure’s life even in harsh conditions.
The Westminster is engineered for ease and reliability. Its steep 45° roof pitch helps to prevent snow buildup, while pre-assembled doors and windows save time during installation. The inward-swinging single door locks securely, and the built-in louvred side vents, combined with automatic roof vents, create consistent airflow and ideal growing conditions. Every detail is carefully crafted in the United Kingdom, combining practicality with timeless style. Decorative Victorian finials are an optional add-on for all sizes.
