Factors Affecting Extension Costs Beyond the Calculator
While our extension cost calculator offers an accurate estimate, it’s just the starting point. There are a few other factors to keep in mind when budgeting for a home extension, as each project can present unique considerations that impact the final cost.
- Planning and Permit Fees
Depending on the scope of your project, you may need to apply for planning permission or building control approval. These fees vary by location and complexity, and while some smaller projects might fall under Permitted Development, others will require formal permission. It’s worth budgeting for these additional costs to avoid surprises. - Professional Fees
Architectural and structural engineering services, structural assessments, and inspections are integral to the success of any project but can add to the overall budget. These services help ensure your extension is well-designed, safe, and compliant with building regulations. Our team at DeVis Architecture can guide you through these requirements, making sure every detail is covered. - Site-Specific Challenges
The condition of your existing property and site can also impact the overall cost. For example, homes in conservation areas or on uneven ground might require additional preparation, such as reinforced foundations or specialist materials. Understanding these potential site-specific costs early on can help you make informed decisions during planning. - Unanticipated Costs
Renovation projects occasionally reveal unexpected issues, such as outdated wiring, plumbing that needs upgrading, or structural reinforcements. While our calculator provides a clear base estimate, it’s wise to have a contingency fund of 10-15% to cover these unforeseen expenses, giving you peace of mind as the project progresses. - Material and Finish Choices
Material costs can vary widely based on quality, brand, and availability. If you’re opting for luxury finishes, unique features, or energy-efficient options, these selections will naturally increase costs beyond a standard estimate. Our calculator helps you visualise how finishes impact the budget, but your actual choice of materials will refine the final figure.
