Why the Alton Durham Greenhouse is the Best Compact Cedar Greenhouse Option

Designed as a scaled-down version of the Alton Cambridge model, the Durham brings all the classic Victorian charm in a more space-efficient footprint. A steep 45º roof pitch prevents snow buildup, while the aluminum foundation lifts the cedar structure off the ground to protect against rot and decay. Reinforced by cast aluminum gussets, the frame offers strength and elegance in equal measure.

Ideal Applications

• Small backyard growing spaces

• Urban and townhome gardens

• Year-round vegetable and herb propagation

• Orchid and bonsai cultivation

• Residential greenhouses with limited square footage

• Educational or hobby greenhouses

Built with a Cedar and Aluminum Combo for Longevity and Style

The Durham stands apart with its aluminum-raised base—a detail that adds years of life to the cedar frame by preventing direct contact with ground moisture. Combined with aluminum bar capping and solid cast gussets at every corner, this greenhouse is engineered for all-season performance with minimal maintenance.

Optimize your greenhouse with optional staging shelves. You can select from 2, 3, or 4-slat options to keep your tools and plants neatly organized and within reach. Enhance the look with solid cast aluminum cresting, allowing you to personalize your Durham Greenhouse to match your gardening style.

Maintenance Tips

• Apply cedar sealant annually to retain wood tone and weather resistance

• Clean glass panels quarterly for optimal light transmission

• Check vents and louvered windows seasonally to ensure smooth operation

• Keep the aluminum base clear of leaves or buildup to promote airflow

• Lubricate hinges and locks once or twice per year
