That’s a must-ask question 👍 — because in almost every project, some changes happen during execution (new finishes, extra storage, shifting layouts). If this isn’t handled transparently, it leads to hidden charges, disputes, and delays.

Here’s how a professional designer in Delhi NCR should handle it:

✅ Standard Process for Handling Design Changes & Cost

Table of Contents

1. Change Request Documented

Any change (e.g., “convert 2-door wardrobe to sliding, change laminate to veneer”) must be put in writing (email/WhatsApp approval).
Designer prepares a Change Order → listing scope, material, brand, and impact.

2. Cost Impact Shared Before Execution

Designer gives you a revised BOQ/line item with cost difference.
Example:
- Laminate wardrobe (₹1,200/sq.ft.) → Veneer wardrobe (₹1,800/sq.ft.)
- Difference: +₹600/sq.ft. × 30 sq.ft. = ₹18,000 extra.
You approve or reject before work starts.

3. Timeline Impact Assessed

Along with cost, the designer must tell you if the change affects project duration.
Example: Veneer requires polishing → adds 7–10 days.

4. Variation Register Maintained

All approved changes are added to a Variation Register (Excel or shared document).
Tracks cost increase/decrease, timeline changes.
Prevents last-minute surprises at billing stage.

5. Final Cost Reconciliation

At handover, you receive a Budget vs Final Cost Report with all changes noted.
Any extra cost should match previously approved changes only.

💡 What You Should Ask Your Designer

How do you document design change requests?
Do you give revised cost estimates in writing before implementing?
How do you track cumulative cost changes?
Do you also share timeline impact for each change?
Can you provide a variation register format you use with clients?

⚠️ Red Flags

Designer says “Don’t worry, we’ll adjust later” 🚩 → no transparency.
Changes are executed without written client approval.
Final bill includes “extra charges” you were never told about.

✅ Pro Tip

Insist on a Change Order system → no change without written approval.
Keep a 10–15% contingency buffer in budget for upgrades/changes.
Ask for a variation tracker in Excel shared weekly.

👉 Do you want me to create a Change Order / Variation Register Template (Excel) with columns for Requested By, Change Description, Cost Impact, Timeline Impact, Approved By so you can use it to keep your designer accountable?
