Extending your home is an exciting opportunity to create more space and enhance your lifestyle, but it’s also a project that requires careful planning. Avoiding these common mistakes can save you time, money, and unnecessary stress:
1. Underestimating Costs
One of the most common pitfalls is failing to budget accurately. Many homeowners overlook hidden costs like council fees, design changes, or site preparation. Always include a contingency fund—10-15% of your total budget is a smart safety net.
2. Poor Design Choices
A poorly planned design can leave your extension feeling disconnected from the rest of your home. Work with an experienced designer or architect to ensure the new space flows seamlessly with the existing structure while meeting your functional needs.
3. Skipping Proper Planning
Rushing into construction without detailed plans is a recipe for disaster. Comprehensive planning, including clear timelines, detailed drawings, and a fixed-price contract, ensures everyone is aligned and reduces the risk of costly changes mid-project.
4. Ignoring Council Regulations
Every council has specific rules for extensions, and the Northern Beaches is no exception. Overlooking these can lead to delays, fines, or even having to redo work. Partner with a builder who understands local regulations to avoid these headaches.
5. Choosing the Wrong Builder
Opting for the cheapest quote often leads to poor workmanship or hidden costs. Instead, choose a builder with a proven track record, transparent pricing, and strong communication skills.
