Premium Construction
-
Mortice & Tenon Joints – A cleverly engineered jointing system that makes assembly straightforward while reinforcing the structure for long-term stability.
-
Western Red Cedar Frame – Naturally rot-resistant, insect-deterring, warp-resistant, and aromatic for decades of low-maintenance use.
-
Aluminum Base Frame – Keeps wood elevated away from moisture, preventing common “rot spots” and allowing glass panels to sit directly on metal for improved water management.
Exceptional Design
-
Classic Cedar & Glass Styling – Half-wood, half-glass construction blends seamlessly into any outdoor setting.
-
3mm Toughened Glass – Crystal-clear, strong, and secure, with no rattling in the frame.
-
Superior Height – 5'7" eaves height—up to 18" taller than many greenhouses—provides better airflow, more headroom, a higher door, and space for overhead shelving.
-
Steep Roof Pitch – Aesthetic appeal plus practical snow-shedding design for all-season use.
Advanced Growing Environment
-
Generous Roof Ventilation – Multiple roof vents with automatic openers included as standard; temperature-responsive operation requires no electricity and ensures optimal airflow.
-
Louver Windows – Additional manual ventilation for precise climate control.
-
Integrated Guttering – Directs rainwater away from the structure and into your collection system; Victorian model features an oversized gutter for greater capacity.
