Very happy with our carport purchased from Modern Steel Buildings. Brett was very helpful in the design stage and provided lots of great advice and support. The carport was delivered and looks great. We had some minor issues with damaged panels on supply, but Brett spoke with the local supplier and the items were replaced at no cost within a few days. Would use Modern Steel Buildings again if we ever need a shed or carport.

Excellent carport. Really shows off the driveway and unit as well as being good protection for the car from the sun. With mine I ordered it a bit longer so I can get my trailer in front of the car so everything looks tidy from the street. Brett was always there if you needed any information at all. Wasn't too long after ordering it that the carport was delivered to my address and may I say well packed and secured with no damage. Would recommend this company. Ian Batchelor.

Made for DIY – “Simply Bolts Together”

Are you ready to put your handyman skills to the test? Our DIY carport kits are perfect for you! You can also save money by arranging your own installation. Whoever is building your carport will find the process easy and quick as all the components are pre-cut to length. This means that there is no major cutting required on site during the construction process. All bearers and rafters are pre-punched and pre-drilled for ease of connection, with a specifically designed bracket for each connection. Your frame will go together like a big Meccano set. However, you will need to drill the holes in the top and bottom of your posts as we are unable to do that for you. Although there can be a bit of cutting and folding involved to correctly fit your gutters and flashings, if you are up for the challenge, then you won’t find a better supplier of DIY carport kits.

Our company, MSB, exclusively uses Australian-made BlueScope and genuine Colorbond® steel for all of our steel buildings. This is because the high-tensile materials used in the manufacturing of Australian steel purlins and girts – either G450, G500, or G550 – guarantee a strong and durable end product. Additionally, the steel is coated with a top-grade galvanised coating with a minimum of Z350 for added protection. Before being sent for production, the steel undergoes rigorous testing to ensure quality and sustainability. We firmly believe that utilising Australian steel in our steel building construction provides unparalleled strength and reliability.

What is the process to obtain council approval?

If you’re planning on constructing a carport on your property, it’s crucial to obtain approval from the council by submitting an application for a planning or building permit. The council will request various documents, which include council application forms that you can obtain from them, engineering and architectural plans that we can provide to you, a site plan that shows the size and position of the structure in relation to property boundaries and other buildings that you can order online or acquire from a local surveyor for around $250 – $500, Form 15 that we can provide to you, and a storm water runoff plan. Once you have all the necessary paperwork, you can submit your application through the building and planning department. It usually takes two to six weeks to receive approval.

What is included in my or carport kit?

At MSB, we provide a comprehensive order that contains all the required components to complete your project. The kit comprises of structural parts, fasteners, guttering, flashings, brackets, and various other small pieces to guarantee a thorough and complete kit.


Our Carports are available in various sizes, including single, double, triple, and 4-bay carports. Some kits are even larger and ideal for commercial use. Most people aim to cover a specific area, usually accommodating 1, 2, or 3 vehicles or more. It’s possible to design the carport roof to a specific size to cover the desired area. However, it’s important to note that a typical car space is three meters wide and six meters long. Therefore, a full car carport should be around 6 meters deep and 12 meters long. Keep this in mind when customizing your carport size.

Can I build my own carport?

If you’re a DIY owner builder in Hervey Bay, you can choose to build a carport or shed on your property. It’s important to know that you’ll need a builder’s license to do so. As an owner builder, you can obtain a license through the Queensland government’s proper channels. This involves a short course that usually takes about half a day and may cost a few hundred dollars. See this link for information on how to become an owner builder in QLD.


Typically, a builder would charge between $15,000 to $30,000 for a custom ground-up carport build, depending on the materials used, size, and roof style. However, purchasing a pre-engineered DIY carport kit can save you a lot of money as it eliminates the design, drafting and engineering step in the process that a builder would charge for, which can be very expensive. If you plan to build the carport yourself, there are no installation costs, which will save you even more money. Alternatively, you can hire a licensed tradesperson to install the carport for you, giving you the flexibility to manage the project and obtain multiple quotes to ensure an economical build. Therefore, purchasing a pre designed and pre-engineered kit and either erecting it yourself or hiring a licensed tradesperson to install it for you can be a lot cheaper than having a builder construct it from the ground up.
