Deconstructing the Costs: What Are You Paying For?
Understanding where the money goes is the first step in planning a successful build. The total cost of a greenhouse can be broken down into three main categories.
The Base Kit & Size
This is the foundational cost, covering the frame and basic hardware. Size is the single biggest factor; doubling the square footage can nearly double the price of the frame. Kits range from simple hoop houses to complex structures, and the price reflects that complexity.
Glazing Material
The “glass” is the next biggest variable. A simple plastic film is the cheapest but least durable. Polycarbonate offers the best balance of durability, safety, and insulation for the price. Glass is the most expensive, offering premium aesthetics but requiring a much stronger and costlier frame.
Essential Extras
A bare greenhouse is just a room. To make it a functional growing space, you need systems. This includes the best greenhouse heaters for year-round use, ventilation for plant health, and the best greenhouse shelving to maximize your space.
Saving Money: DIY vs. A Kit
Can you save money by building from scratch? Potentially, yes—if you have the skills, tools, and time. Our guide on how to build a greenhouse at home is a great resource for ambitious DIYers.
