7 Interior Mistakes That Can Cost You Lakhs
From finalising designs before electrical planning to choosing the wrong plywood grade, these are the costliest avoidable errors.
Why small decisions become expensive
Most interior overruns come from rework, not from expensive materials. Once walls are painted and furniture is installed, changing an electrical point or a wardrobe size costs far more than planning it right the first time.
The seven mistakes
1. Skipping a detailed furniture layout before electrical work. 2. Using MR-grade plywood in wet areas such as kitchens and bathrooms. 3. Designing for looks before storage. 4. Ignoring lighting layers. 5. No written scope or specification sheet. 6. Choosing finishes from small samples only. 7. Not keeping a 10–15% contingency.
How to avoid them
Freeze the layout first, then electrical, then materials, then finishes. Ask for a written bill of quantities with brand and grade for every major item.
