Full Home Interior Cost Calculator

No, use the enclosed carpet area of the flat only. Balconies and utility areas are typically priced separately if they need design work at all, since the finish requirements differ from indoor rooms.

This tool gives a proportional share of your total budget for the kitchen. The dedicated kitchen calculator prices it independently by actual shape and running length, which is more accurate if the kitchen is your priority room.

Structural or civil changes such as moving a wall, plumbing relocation, and the interior designer's own professional fee where charged separately from execution. Ask explicitly whether your quote is design-and-build or design-only.

Ten to fifteen percent above the estimated total is a reasonable buffer for most projects. Interior projects routinely uncover minor unplanned civil work once execution begins — a damp wall, an electrical point in the wrong place — and a contingency avoids that becoming a budget crisis.
