A Guide To Renovation Budgeting: How to Plan Costs & Avoid Unexpected Expenses

Danielle Tanner is a designer at Topology with over five years of experience in the interior design and renovation industry. Having also completed two home renovations of her own, she brings a grounded, real-world understanding of what it takes to plan, budget, and deliver a successful project.

In this episode, host and interior designer Athina Bluff sits down with Danielle to explore the often-overlooked reality of renovation budgeting and the importance of approaching a project with clarity before any work begins. Danielle explains why setting a realistic budget from the outset is essential, and how a well-prepared scope of work can help prevent unexpected costs and keep a project on track.

The two talk through the process of gathering and comparing builder quotes, and why itemised breakdowns are crucial for understanding where your money is going and identifying potential discrepancies. Danielle also highlights the hidden costs that frequently catch homeowners out, from painting and flooring to waste removal, site setup, and temporary accommodation during larger-scale renovations.

The discussion emphasises contingency planning. Danielle advises a 10–15% budget buffer for unforeseen issues or price changes. She stresses tracking every expense to maintain control and explores affordable design upgrades that provide refinement through thoughtful, incremental changes.

This conversation is about the often messy balance between design dreams and the practical reality of budgets. It’s a reminder that true confidence in a renovation doesn’t just come from a mood board; when you bring your creative vision and your financial planning closer together, you’re not just building a space—you’re creating a foundation for a home that feels as good as it looks.
