Types of Greenhouse Structures: Choosing the Right Design for Your Needs

Greenhouses have long been essential tools for horticulturists, farmers, and gardening enthusiasts, providing controlled environments to nurture plants and extend growing seasons. Among the myriad designs available, three prominent types of greenhouse structures stand out: the Gothic arch greenhouse, the hoop house, and the traditional greenhouse frame structure. Each offers unique benefits and characteristics, catering to different needs and preferences.

Greenhouses are essential for controlled-environment agriculture, offering protection from harsh weather and extending growing seasons. The structure of a greenhouse significantly impacts its durability, energy efficiency, and suitability for different crops. This article explores the most common types of greenhouse structures, including Gothic arch greenhouses, hoop houses, Venlo glass greenhouses, and more, to help farmers and commercial growers make informed decisions.

1. Gothic Arch Greenhouse  

Best for: Snow-prone regions, high wind resistance  

 

Key Features:  

Peaked roof design – Sheds snow and rain efficiently  

Strong structural integrity – Uses hot-dip galvanized steel (zinc coating ≥275g/㎡)  

Wider growing space – Vertical sidewalls allow better air circulation  

Long lifespan – 20+ years with proper maintenance  

 

Common Applications:  

- Commercial vegetable farming (tomatoes, cucumbers)  

- Flower cultivation  

- Cold-climate growing  

 

Construction Specs:  

- Frame: 120×120×3.0mm main columns, 50×50×2.0mm crossbeams  

- Covering: Polycarbonate panels or double-layer polyethylene film

2. Hoop House (Quonset Greenhouse)  

Best for: Low-cost seasonal farming, small-scale growers  

 

Key Features:  

Semi-circular shape – Easy to assemble, minimal materials  

Affordable – Lower construction cost than rigid-frame greenhouses  

Portable options – Some designs allow relocation  

Good light transmission – Single or double-layer polyethylene film  

 

Limitations:  

- Less snow/wind resistance than Gothic arch  

- Shorter lifespan (5-10 years)  

 

Common Applications:  

- Seasonal crop extension (lettuce, herbs)  

- Nursery seedling production  

 

Construction Specs:  

- Frame: Galvanized steel pipes or PVC  

- Covering: 6-12 mil polyethylene film

3. Venlo glass greenhouses (Dutch Style)  

Best for: High-tech commercial farming, hydroponics  

 

Key Features:  

Modular glass panels – Excellent light transmission (>90%)  

Optimized ventilation – Roof vents for heat and humidity control  

Durable structure – Aluminum alloy + tempered glass  

Scalable design – Easy expansion for large farms  

 

Common Applications:  

- Hydroponic lettuce & herbs  

- Floriculture (roses, orchids)  

- Research & breeding facilities  

 

Construction Specs:  

- Frame: Aluminum profiles with glass clips  

- Roof vents: Automated rack-and-pinion system

5. Sawtooth Greenhouse  

Best for: Tropical/subtropical climates  

 

Key Features:  

Asymmetrical roof – One side higher for natural ventilation  

Reduced heat buildup – Louvers or vents on the steeper side  

Common in industrial farms – Used for orchids, foliage plants

Choosing the Right Structure  

 

| Type            | Best Climate       | Cost       | Lifespan    | Best For            |  

|----------------------|-----------------------|---------------|----------------|------------------------|  

| Gothic Arch      | Cold/snowy regions    | $19800           | 20+ years      | Tomatoes, cucumbers    |  

| Hoop House       | Mild climates         | $ 29800            | 5-10 years     | Seasonal vegetables    |  

| Venlo Glasshouse | All climates          | $39800          | 30+ years      | Hydroponics, flowers   |  

| A-Frame          | Temperate zones       | $29800            | 10-15 years    | Home gardening         |  

| Sawtooth         | Hot/humid regions     | $25000           | 15-20 years    | Orchids, tropical crops|  

 

Choosing the Right Greenhouse Structure

When selecting a greenhouse structure, several factors need to be considered. These include the intended purpose of the greenhouse, the available space, the local climate, and the budget. For those looking for an aesthetically pleasing and durable option that can withstand harsh weather, the Gothic arch greenhouse is an excellent choice. On the other hand, if simplicity and cost-effectiveness are priorities, the hoop house may be the way to go. For those who require a versatile and customizable solution with optimal light transmission, the traditional greenhouse frame structure is a reliable option.

 

 

Conclusion  

The right greenhouse structure depends on climate, budget, crop type, and scale of operation. Gothic arch greenhouses excel in durability for commercial growers, while hoop houses offer affordability for seasonal use. For high-tech farming, Venlo glass greenhouses provide superior climate control.
