EROCK 812
8 × 12 ft · 96 sq ft
A compact garden greenhouse for a small backyard.
Timeless conservatory architecture. A distinctive elevated ventilation turret. Designed for the beauty of every season.
Our signature concept pairs a classic rectangular greenhouse with a centrally positioned, fourteen-sided turret that rises above the main roofline to promote natural ventilation.
Designed around a modular, bolted aluminum frame and translucent multiwall polycarbonate, the EROCK 1830 balances architectural elegance with a practical path to repeatable manufacturing.

A greenhouse that connects to the house, with a single-slope glazed roof and a carefully detailed wall connection.
All models are design concepts, not engineered or available-for-sale products. The attached model requires house-wall waterproofing, snow-shedding and drift analysis, foundations, permits, and structural connection design.
All prices are preliminary planning estimates in USD, not binding offers. Installed pricing, foundation, engineering, site preparation, permits, freight, and options are subject to final quotation and location.
The architecture is defined; structural member sizing, connection design, and load ratings remain subject to licensed engineering review.
Modular structural members and gusseted joints designed for efficient fabrication, shipping, and assembly without field welding.
High operable vents create a potential escape route for rising warm air, complemented by low-level intake ventilation.
Insulating translucent panels with glazing details and support spacing to be selected for the final engineered design.
Early architectural renderings of the EROCK greenhouse concept. Actual manufactured details may differ.
We're exploring a complete installation offering for homeowners who want an extraordinary greenhouse without coordinating multiple contractors.
Every property is different. Final pricing depends on site conditions, permitting, foundation engineering, options, and verified manufacturing costs.
