This T-shaped greenhouse and garden room combines a full-glass growing space with a clean, minimal structural design. Its frame is constructed from heat-treated Thermowood®, while tempered safety glass covers the structure to provide clear views and abundant natural light.
The structure offers 174 sq. ft. of internal area with a wide, threshold-free double-door entrance and 2 roof windows fitted with automatic openers. Its T-shaped layout is designed for growing plants while also allowing the enclosed space to serve as a garden room, studio, dining area, or other multipurpose outdoor space.
Built as a made-to-order kit, the structure arrives with pre-cut framing, glazing panels, hardware, and step-by-step assembly instructions. A level, prepared foundation is required before installation.
Key Features
Thermowood® Frame: Constructed from Scandinavian pine treated with heat and steam without chemical additives to improve stability and resistance to decay.
Full Tempered Safety Glass: Uses 5/32 in. (4 mm) tempered safety glass throughout the structure.
High Natural Light Transmission: Tempered glazing allows up to 93% of daylight to pass through.
Safety Glazing: Tempered glass is designed to break into blunt granules rather than sharp shards if subjected to sufficient impact.
Wide Threshold-Free Entrance: Features a wide double door with a lock and threshold-free entry.
Automatic Ventilation: Includes 2 roof windows equipped with automatic openers.
Weather Load Ratings: Rated for a snow load of 51 lbs./sq. ft. and a sidewind load of 70 mph.

Made-to-Order Construction: Supplied as a pre-cut kit manufactured to order.
Prepared Foundation Required: Installation requires a level, load-bearing base. A concrete slab or strip foundation is recommended.
