Many people fully believe that their home is their castle, a place of refuge and relaxation. Yet, invariably, people believe their castle needs a little extra space. Whether it’s for a workshop, a barn, a garage, or just some extra storage, a metal building can be a great way to extend your home. Metal buildings are durable, cost-effective, and can be customized to fit your needs. However, with so many options available, it can be a bit overwhelming to know where to start. This article will guide you through the process of selecting the right metal building for your home extension needs.

Determine the Purpose

The very first step for most when it comes to choosing the right metal building is to determine its purpose. Metal buildings can serve a variety of functions, including:

Utility Buildings

These are usually general-purpose buildings that can be used for storage, as a workshop, or for any other use that requires a secure, enclosed space. They’re great for hobbyists etc.


These are smaller structures that can be used for specific purposes, such as a garden shed, a chicken coop, or a dog kennel. The vary in form, but they’re essentially buildings that are detached from the main house.


Metal barns are larger structures that are typically used for agricultural purposes, such as housing livestock or storing hay and equipment. They can range from completely secure (when storing equipment) to being open to the air.


Metal garages are designed to house vehicles. These are usually cars and trucks, to boats and RVs.

Once you have determined the purpose of your metal building, you can start to consider other factors such as size, design, and customization options.

Choose the Right Size

The size of your metal building will depend on its intended use and the amount of space available on your property in question. For example, a small garden shed may only need to be 10×10 feet, while a large barn or garage may need to be 40×60 feet or larger. It’s important to carefully measure (to the last CM) the space available and consider the future needs of your metal building. Remember to also consider the height of the building, especially if you plan to store tall items or need space for a loft or mezzanine.

Consider the Design

The design of your metal building is another important factor to consider. Most metal building suppliers offer a variety of design options, from basic, utilitarian structures to more elaborate designs with decorative features. Consider the style of your home and the surrounding area when choosing the design of your metal building. You may want a building that matches the style of your home or one that stands out as a unique feature on your property.

Customization Options

Many metal building suppliers offer customization options that allow you to tailor the building to your specific needs. This may include adding windows and doors, choosing the color of the metal, adding insulation, or including electrical and plumbing fixtures. Make a list of the features that are most important to you and discuss them with your supplier to determine the best customization options for your metal building.

Browse Through a Photo Book

Some metal building businesses provide a glossy photo book that you can flick through as a brochure to help you decide. These photo books often include images of completed projects, which can give you an idea of the design and customization options available. It can also help you visualize how your metal building will look once it is completed. If your supplier does not provide a photo book, ask to see a portfolio of completed projects or visit their website to view images of their work.

Consider the Cost

The cost of a metal building will depend on a whole host of factors, including the size, design, and customization options available to you. It’s important to have a budget (make sure you fully calculate every cost) in mind before you start the selection process. However, it’s also important to be flexible and consider the long-term value of the building. A well-designed, durable metal building can be a valuable addition to your property and may be worth the investment.

Installation Process

Once you have selected the correct and appropriate metal building (which might take some time), the next step is the installation process. Most metal building suppliers offer installation services, but it’s important to discuss this upfront. Some suppliers may include installation in the cost of the building, while others may charge an additional fee. It’s also important to consider the foundation for your metal building. Some buildings may require a concrete foundation, while others can be installed on a gravel or dirt surface. Discuss the foundation requirements with your supplier and make the necessary preparations before the installation begins. Additionally, check with your local municipality about any permits or approvals needed before installation.
