Love your home but feel like you’ve outgrown the space? A home extension could be the perfect solution. Whether you’re dreaming of a bigger kitchen, an extra bedroom, or a dedicated space for entertaining, extending your home allows you to add the room you need without the hassle of moving. But as exciting as it is to plan for that extra space, it’s important that you are aware and prepared for the challenges along the way. In this blog post, we’ll discuss six of the most common challenges homeowners face during the home extension process so you can be fully aware of the hurdles you might face if you decide to extend your home.
1. Navigating the Council Approval Process

Before you can start knocking down walls, you need to get approval from the local council and in Brisbane, this can be more complex than you would have thought. Each suburb can have its own set of rules and regulations, depending on the type of extension you’re planning. There are zoning laws to consider, heritage overlays that may limit changes to older homes, and specific building codes that must be followed. If these requirements aren’t met, you could face delays, costly revisions, or outright rejection of your plans. That’s why this step can often feel like a maze of paperwork, technicalities, and red tape. It’s no wonder homeowners find this part of the process frustrating. To make life easier we recommend working with a private town planner who can lodge applications on your behalf, or if you work with us we have our partnered town planners who we use and have an excellent track record of quickly navigating all of the council’s red tape.
2. Unexpected Delays
Delays are one of the most stressful parts of a home extension project. Even with the best planning, unexpected issues can sometimes come up. For instance, Brisbane’s weather can be a big factor. Sudden storms or weeks of rain can push back your initial timeline. Other than the weather, there’s always the possibility of material shortages or delivery delays, and some contractors might have scheduling conflicts. These delays can slow down your project significantly which is very frustrating if you’re eager to enjoy your new space or if you’ve planned the extension around a specific event like hosting the family during the holidays.
3. Budget Overruns

One of the biggest concerns of any homeowners is going over their intended budget. Unfortunately, budget overruns are common in house extension projects. You might run into structural issues like discovering that you need to reinforce your existing foundation or the electrical wiring needs to be upgraded. Prices of materials can fluctuate, too, especially for items like timber, steel, or custom fittings. Understanding the typical costs associated with house extensions can better help you when you’re budging for a house extension and avoid financial surprises. Additionally, working with a builder that provides a fixed-price building quote will take the risk of unexpected costs in the hands of the builder instead of having to fork it out yourself. This also encourages the builder to be stringent and pay close attention to all the details.
4. Design Changes Mid-Project
It’s completely normal to change design elements once construction has started. What was on paper might not translate very well in real life. However, making changes once the project is underway can cause significant disruptions. Even small adjustments can have a ripple effect, requiring alterations to other parts of the build. These changes can lead to delays, increased costs, and logistical challenges. For example, switching out materials might mean waiting on new deliveries or changing the entire layout could result in extra work for the contractors.
5. Disruptions to Daily Life
Living through a renovation is difficult especially when it’s a large project like a home extension. The constant noise, dust, and general commotion can disrupt your daily routine. If you’re living in your home during construction, you might find it challenging to maintain a sense of normalcy. Cooking, working, or relaxing can feel difficult when your home is in a construction zone. Aside from that, having contractors coming in and out of your house can feel invasive and dealing with the mess that comes with the construction can feel overwhelming.
6. Ensuring Structural Compatibility

Blending the new extension with your existing structure can be trickier than it seems. For older homes, matching foundations and materials requires careful planning. You want the extension to look and feel like a natural part of your home, not a tacky stand-out addition. However, achieving that seamless look can be challenging. If the new structure doesn’t align with the old, you could face problems like uneven floors or an obvious transition from old to new. Older homes might also have structural quirks that need to be addressed before the extension can be added which can lead to more work and extra costs.
