Is it Cheaper to Build or Buy a Greenhouse? A Cost Comparison Analysis

 

A greenhouse is an excellent way to extend your growing season, protect your plants from harsh weather conditions, and grow a wider variety of plants.

When considering adding a greenhouse to your gardening setup, a key decision you'll face is whether to build one from scratch or purchase a pre-made greenhouse.

The decision to build or buy a pre-made greenhouse is not straightforward, as there are many factors to consider. However, when speaking strictly about costs, buying a pre-made or ready-to-assemble greenhouse kit is less expensive.

In this guide, we will explore the cost analysis of building and buying a pre-made greenhouse and the factors influencing the costs.

Cost Analysis of Building a Greenhouse

Building a greenhouse can be a rewarding DIY project, but it requires time, effort, and money.

Generally, the cost of building a greenhouse can vary widely depending on the size, materials, and design of the greenhouse.

Here is a breakdown of the costs involved in building a greenhouse.

1)      Materials

The biggest expense of building a greenhouse is the choice of materials. The costs of different materials vary significantly and determine the overall expense of your greenhouse building project.

Common frame materials for building greenhouses are wood, PVC, and aluminum.

•         Wood: Affordable but requires regular maintenance to prevent rotting and warping.
•         PVC: lightweight and easy to install, but not durable.
•         Aluminum: Most expensive, but it is strong, durable, and requires minimal maintenance.

In addition to the frame, you will need to purchase glazing materials such as glass or polycarbonate panels.

Glass is the most expensive option, but it is also the most durable and provides the best insulation. Polycarbonate panels are more affordable and lightweight, but they do not provide as much insulation as glass.

2)     Labor Costs

Building a greenhouse isn’t a simple DIY project, as it requires some level of expertise. If you have the skills and time to construct a greenhouse yourself, you can save on labor costs.

However, if you’re not experienced in DIYing greenhouses, you'll need to hire a professional for construction, and the expenses will increase. 

3)     Time Investment

Building a greenhouse is time-intensive. You need to invest a significant amount of time into designing, planning, and constructing your greenhouse.

The amount of time required to build a greenhouse depends on the size of the project and your level of expertise. Smaller projects can take 40 to 50 hours, while the larger and more complex can take several weeks to complete.

4)  Engineering Codes

Building a greenhouse is, in many ways, comparable to building a house. You simply don't put up a structure without following some form of building regulations.

Most states will require you to follow the local building codes. Plus, you may also be required to show stamped engineering codes to get a permit.

In conclusion, building a greenhouse isn't necessarily as cheap or cost-effective as many people think. DIYing a greenhouse comes with plenty of expenses, so you need to consider your options and budget carefully.

Cost Analysis of Buying a Greenhouse

 

In this section, we'll consider the cost analysis of buying a premade or pre-built greenhouse. Cost aside, the biggest upside of buying a pre-made greenhouse is the convenience and time-saving.

1)  Pre-built Greenhouse Prices

The biggest expense of a pre-built greenhouse is the initial one-time upfront payment. The upfront payment for greenhouses depends on factors like size, materials, and additional features.

While this cost might seem higher initially, you must compare it to the total expenses of building a greenhouse from scratch.

2)  Installation Fees

In addition to the cost of the greenhouse itself, you must consider the installation fee. The installation fee generally depends on the size of the greenhouse. However, some companies may offer free installation.

If you're handy with tools and have some DIY skills, you can save on the installation fee. Most pre-made greenhouses are designed for easy assembly. They come with detailed instructions and user-friendly features for quick assembly.

3)      Warranty and Support

Most commercially purchased greenhouses usually come with warranties and support. This is advantageous in case of defects or issues with the structures, thus providing peace of mind and potential cost savings in the long run.

Pros and Cons of Building Vs. Purchasing a Pre-made Greenhouse

Cost aside, there are several other factors you need to consider when deciding whether to build or buy a greenhouse. We will explore the pros and cons of each option to help you make an informed decision.

Customization and Control

The greatest benefit of building your greenhouse from scratch is that it offers an unmatched level of customization and control over the design and material.

For example, you can choose the size, shape, and materials to suit your specific plant-growing needs.

On the other hand, buying a greenhouse kit or a pre-built greenhouse may limit your options for customization and control. Of course, there're different greenhouse kits in the market, but they may not offer the same level of flexibility as building from scratch.

It's important, therefore, that you consider the pre-made greenhouse with the extra features you're looking for. For example, some pre-made greenhouses come with extra features such as ventilation, temperature control systems, and shelving. But understand that while these features enhance functionality, they may contribute to a higher overall cost.

Convenience and Speed

A major highlight of buying a pre-made greenhouse is that it’s a more convenient option. Everything from sourcing to assembly is much easier on a pre-made greenhouse than building from scratch.

Pre-made greenhouse kits will typically come with the necessary materials and instructions for assembly, allowing you to start gardening much quicker than building a greenhouse from scratch.

The pre-made greenhouses are generally much easier for beginner gardeners or gardening enthusiasts with limited time and experience.

Cost Comparison and Considerations: Which Option Should I Pick?

 

Here is what you need to consider when choosing between a pre-made and building a greenhouse from scratch.

Budget Constraints

Assessing your budget is crucial when deciding between building or buying. While building a greenhouse may seem cost-effective at first, unexpected expenses can arise during construction.

You must compare the total estimated cost of each option to determine the most financially viable choice.

Time and Effort

Consider the time and effort required for building and assembling a greenhouse. For example, if you have limited time or lack construction skills, buying a pre-made greenhouse may be a more practical choice.

Customization

Building your greenhouse allows for greater customization to suit your specific needs and preferences. If customization is a priority and you have the skills to implement it, building might be the better option.

Local Climate

Consider the climate of your region. Certain climates may require specific features or materials in a greenhouse, and pre-made options might be designed with these considerations in mind.
