Extending your home is one of the best ways to create more space and add value without the cost of moving. But for many Brisbane homeowners, the planning stage can feel overwhelming. Between design choices, council approvals, and budget management, it’s easy to see why.
The good news? With the right guidance and process, planning a home extension doesn’t have to be stressful.
Step 1: Clarify Your Goals
Before diving into drawings, take time to define what you actually need from your extension. Are you after an extra bedroom, a larger living space, or better indoor-outdoor flow? The clearer your goals, the more efficient the design process becomes.
Step 2: Get Advice Early
Engaging a builder early in the design phase helps ensure your ideas match your budget. At Watcon Constructions, we regularly work alongside architects and designers to provide buildability and cost feedback — saving clients from expensive redesigns later.
Step 3: Understand Brisbane’s Building Rules
Extensions in Brisbane often fall under “small lot” or character area overlays, which can affect setbacks, heights, and design requirements. Knowing these early avoids approval delays. We can guide you through this process or work with your designer to prepare compliant plans.
Step 4: Plan Your Budget and Timeline
Every extension is different, but planning realistic budgets upfront is key. Factors like site access, structural complexity, and material choices can all affect cost. A detailed quote (not just an estimate) gives you financial confidence before construction begins.
Step 5: Choose the Right Builder
The builder you choose determines your renovation experience. Look for someone who:
- Communicates clearly and regularly
- Provides detailed quotes and contracts
- Has a proven record of similar projects
- Takes ownership from start to finish
At Watcon Constructions, we pride ourselves on a straightforward, transparent process that keeps you informed and stress-free throughout the build.
Step 6: Enjoy the Result
A well-planned extension feels seamless — like it’s always been part of your home. With thoughtful design and precise workmanship, you’ll gain not just more space, but a home that truly suits your lifestyle.
