Make sure the budget includes all the materials and designs that will be made later.

3. Calculate the cost of Materials and services

After determining the general budget, you need to calculate the cost of materials and services needed to build a 2-story house. Material costs include various building materials such as concrete, bricks, glass, pipes and more.

Meanwhile, service fees include labor costs for masons, carpenters and electricians.
