使い方
計算式
Total Construction Cost = Built-up Area (sq ft) × Number of Floors × Cost per Sq Ft 計算例
Building a 2,000 sq ft standard 2-story home at 160 per sq ft yields an estimated total cost of 320,000, with roughly 96,000 (30%) allocated to the structural frame and foundation.

よくある質問
What are the major cost components of building a house?
Residential building costs typically divide into: Foundation and Civil Structure (28-32%), Interior/Exterior Finishing (20-25%), Roofing and Framing (12-15%), Plumbing and Sanitation (8-10%), Electrical Wiring and Lighting (8-10%), Doors and Windows (6-8%), and HVAC/Insulation (6-8%).
Does this estimate include land acquisition and municipal permit costs?
No. Construction cost estimates cover civil works, materials, and labor from groundbreaking to completion. Land costs, architectural blueprints, municipal permits, connection utility fees, and property taxes must be budgeted separately.
What causes construction costs to exceed initial estimates?
The most common drivers of cost overruns are soil/foundation surprises during excavation, change orders after framing has commenced, delays in specialty material deliveries, and upgrading interior finishes (fixtures, marble, appliances) midway through the build.
How much contingency buffer should I maintain in my budget?
Professional general contractors and banks recommend budgeting a minimum 10% to 15% contingency reserve above the estimated construction total for unforeseen site issues and price variations.
