🏠 Home Renovation Planning: Budgeting, Permits and Avoiding Costly Mistakes

A practical framework for planning a home renovation, from realistic budgeting and contractor vetting to understanding when permits are legally required.

Pick a room, set the scope of work, and watch a 3D house model plus a live budget tower show where the money goes — and whether the work legally requires a permit.

🔬 What It Demonstrates

Renovation cost scales with scope (cosmetic → full gut) and room type, while a contingency reserve is set aside before spending. A permit flag rises automatically for structural additions, any wiring/plumbing/load-bearing work, or a sufficiently invasive gut renovation.

🎮 How to Use

Set your total budget, choose a room, drag the scope slider from cosmetic to full gut, and adjust the contingency reserve. Toggle the structural/wiring/plumbing switch to see how it forces a permit requirement regardless of scope.

💡 Did You Know?

Renovation cost overruns most often come from unpermitted structural surprises discovered mid-project — which is exactly why experienced renovators hold back 10–20% of budget as a contingency reserve before work even starts.
