1. What is the Building Cost Calculation?

The Building Cost Calculator estimates total construction costs by summing up the major components: foundation, framing, roofing, and finishing costs. This provides a comprehensive view of the total investment required for a construction project in New Zealand.

2. How Does the Calculator Work?

The calculator uses a simple additive formula:

Where:

• \( Foundation \) — Cost of foundation work (NZD)
• \( Framing \) — Cost of structural framing (NZD)
• \( Roofing \) — Cost of roof construction (NZD)
• \( Finishing \) — Cost of interior/exterior finishing (NZD)

Explanation: The equation sums up all major construction components to provide a total building cost estimate.

3. Importance of Accurate Cost Estimation

Details: Accurate cost estimation is crucial for budgeting, securing financing, and avoiding cost overruns in construction projects.

4. Using the Calculator

Tips: Enter costs for each component in NZD. All values must be positive numbers. For accurate results, use current market rates for each component.

Q2: What affects framing costs?
A: Framing costs vary based on materials (timber vs steel), building size, and design complexity.

Q3: Are roofing costs per square meter?

Q4: What's included in finishing costs?
