Estimating the cost of building a new home helps plan for the features you want, while staying within your basic budget. American home-building calculations exclude the property price, planters, driveway, sidewalks and landscaping around the property. The estimate also excludes pre-construction work such as lot grading and connecting utilities. Building costs vary with the individual contractor mark-up, geographic location and area labor costs.
