Carports for an Overflowing Garage

March 11, 2020

Last Updated: October 2026

If your garage is too full to accommodate all your vehicles, a carport can provide extra covered parking without the need to build a completely enclosed garage.

It can be designed to shelter a second car, a caravan, a boat or other equipment while complementing your home’s existing roofline and outdoor space.

The best carport for your property will depend on how much room you have, what you need to store, where the structure can be positioned and how it will fit with your home. Roof style, materials, drainage, access and your budget will also influence the design and overall cost.

For Brisbane homeowners, it’s worth considering these details early, along with the relevant building and planning requirements. Let’s explore carport design options, where to position a new structure, which materials to consider and what can affect the cost of adding extra covered parking.

Adding a Carport to Your Property: Design, Materials and Costs

Whether you have an over-flowing garage or have turned your garage into a home office, we can design and build a quality carport to suit your needs.

When Does a Carport Make More Sense than a Garage?

A carport may suit homeowners who:

  • Need covered parking for a second car or a visiting vehicle.
  • Own a caravan, boat, trailer or four-wheel drive that does not fit in the existing garage.
  • Have converted their garage into a home office, gym or workshop.
  • Want weather protection without building a fully enclosed garage.
  • Want to make better use of an existing driveway or side area.

How Do You Choose the Location of Your Carport?

The location of the carport is important when considering what is possible to be built. There are important considerations such as:

  • Available space: Can the carport fit without obstructing access to the house, garage or backyard?
  • Vehicle dimensions: Account for mirrors, roof racks, accessories, opening doors and room to manoeuvre.
  • Driveway access: Consider turning space and whether the vehicle can enter and leave safely.
  • Ground conditions and drainage: The design should account for the site, foundations and where roof water will go.
  • Property boundaries: Check the applicable setbacks and planning requirements before settling on a design.

What Approvals are Needed for a Brisbane Carport?

Brisbane City Council’s requirements depend on the property, applicable codes and overlays. Building approval is required for a carport on an existing house. If you’re outside Brisbane, make sure to check with your local council. Carports on standard house blocks often require a relaxation from council due to proximity to a boundary. For carports close to a side boundary, you may also have to get an agreement from your neighbour.

How Do You Ensure the Carport is Suitable for Your Vehicle?

Some vehicles have specific requirements when considering the suitability of a carport. If the access to a carport isn’t a straight 180 degrees, it may be necessary to consider the clearance to any vehicle as it is turning as well as any obstacles in the area. For vehicles other than standard passenger cars, there may be some height requirements, including if there are roof mounted accessories.

How Can You Design a Functional but Stylish Carport?

The design of the carport takes into account the style of build as well as the materials which are used in its construction.

What are the Carport Roof Options?

Ideally the carport design should complement the existing street view of the house. There are 3 common roof designs for carports:

  • Flat: A simple, understated look that often suits modern homes.
  • Skillion: A single sloping roof plane that can complement contemporary homes and suit a range of attached carport layouts.
  • Gable: A pitched, two-sided roof that can complement traditional homes and create a more prominent architectural feature.

Consideration should also be given to the engineering of the carport as to whether it needs to be attached to the existing house or can be a freestanding structure.

What Materials are Available for Carports?

Some designs lend themselves to particular materials more than others. With timber and steel being the most common choices of framework, it’s helpful to consider the suitability of selected materials in relation to visual appeal, maintenance required, warranties and cost.

  • Steel framing: High durability and versatility with low maintenance.
  • Timber framing: Great visual appeal when the right timber has been selected and maintenance is done properly.
  • Single-skin metal roofing: A practical option where upfront cost is a priority.
  • Insulated roof panels: Worth considering if reducing heat beneath the carport is important, particularly in Brisbane’s hot summers.
  • Clear roofing sections: May help bring natural light into a darker side area, depending on the layout and sun exposure.

How to Budget for a Carport

The cost of a building a carport can vary depending on all the considerations we have presented above. The most important outcome is always “value for money”. Ensure that if you are going to invest in the addition of a carport structure to your home, you get the function and look you want and the best quality carport you can get for your money.

What are the Most Common Budget Considerations?

  • Flat/skillion roof structures are usually more economical than gable roof structures.
  • Pre-engineered standard steel structures are usually more economical than custom designed timber frame structures.
  • Single skin metal carport roofs are more economical than insulated panel carport roofs.
  • Structures attached to a house are usually more economical than freestanding structures.

Frequently Asked Questions

Is a carport cheaper than building a second garage?

A carport will often cost less than a fully enclosed garage because it generally requires fewer building materials and less construction work. However, the final cost depends on the size, design, foundations, materials, site conditions and approval requirements. Compare quotes based on the same specifications before deciding.

What size carport do I need for a caravan or boat?

The carport needs to accommodate the vehicle’s full length, width and height, including roof-mounted accessories. Allow additional space for manoeuvring and access where possible. Measure the vehicle carefully before choosing a design, and discuss any unusual clearance requirements with your carport builder.

Which carport roof is best for hot Brisbane weather?

The right roof depends on your priorities, budget, orientation and the way you use the space. Insulated roof panels can help reduce heat transfer compared with a basic single-skin metal roof. A suitable design should also account for drainage, ventilation and the site’s exposure to sun and weather.

What information should I prepare before requesting a carport quote?

Measure the vehicles you want to shelter, identify the preferred location and take photos of the surrounding house and driveway. It also helps to consider your preferred roof style, materials, budget and any extra features, such as lighting or privacy screening. This information gives the builder a clearer starting point for assessing the project.
