Renovation Cost Estimator

Science & Engineering

Full/half-package estimate by floor area

Quick Answer

Renovation Cost Estimator: Full/half-package estimate by floor area. Renovation Cost Estimator uses standard science & engineering formulas to compute accurate results instantly.

Budget = area × unit price. Typical: basic ¥800–1200, mid ¥1500–2000, premium ¥2800+ per m². Reserve 10–20% contingency.
Basic (¥800/m²)80,000CNY
Mid-range (¥1500/m²)150,000CNY
Premium (¥2800/m²)280,000CNY

Step-by-step（mid-range example）

100 m² × ¥1500/m² = 150,000 yuan

Labor onlyYou buy all materials≈60–70%
Half-packageContractor: labor + auxiliaries; you: main materials≈75–85%
Full-packageEverything included100%
Quotes above cover hard renovation only — furniture, appliances and soft furnishing typically add another 30–50%. The most common budget killer is mid-project additions: lock the item list and unit prices in the contract, and hold 10–20% contingency rather than expanding scope.
