Alton Cambridge Cedar Greenhouse- Aluminum Base
Discover the ideal balance of architectural elegance and robust functionality with the Alton Cambridge Cedar Greenhouse.

Why the Alton Cambridge T-Shaped Greenhouse Stands Out
Designed with the same timeless appeal as the Durham model but scaled up for added functionality, the Cambridge greenhouse combines aesthetics with intelligent engineering. Its steep 45º roof pitch prevents snow build-up, while the aluminum base and bar capping protect the cedar framing from long-term moisture exposure. Whether you're cultivating year-round or hosting garden events, this greenhouse delivers both form and function.

Ideal Applications
-
Year-round fruit, vegetable, and herb cultivation
-
Orchid and tropical plant propagation
-
Seed starting and early growth stages
-
Garden conservatory or tea room
-
Educational gardening for schools or institutions
-
Luxury backyard statement piece
Built to Withstand the Seasons with Cedar and Aluminum Construction
What sets the Cambridge apart is its dual-material construction. The aluminum base elevates the cedar frame 2 inches above ground level, helping prevent water infiltration while improving frame longevity. Cast aluminum gussets add stability to every framing joint, and bar capping secures each glass panel while shielding cedar from rain and UV exposure.
Customize Your Greenhouse with Practical Accessories
Personalize your Cambridge Greenhouse with features like 2-slat or 4-slat staging shelves. These additions help keep your plants, pots, and tools organized while enhancing functionality. You can also introduce a touch of elegance with solid cast aluminum cresting, giving your greenhouse a sophisticated, classic appearance.
Please Note: Effective 05/01/2025 All Cambridge Greenhouse will be stocked as "fully loaded"; this includes Aluminum Capping, slatted shelving and Victorian Cresting. You can still purchase a not fully loaded kit, but it will be a special order and could lead to a longer ship time.

-
Wipe down glass panels regularly to maximize light intake
-
Lubricate hinges and locks once a season
