When building a house, most of the budget goes toward the main construction work, engineering systems and finishing. Design usually represents a much smaller part of the total budget, while the actual construction can account for more than 90% of the investment.
A significant part of the budget goes into the foundation and structure: concrete, reinforcement, masonry, floors and the roof. These elements form the main structure of the house and are difficult to change later.
Another major expense is the engineering systems. Electrical work, water supply, sewage, heating and ventilation can significantly increase the final cost.
Finishing also takes up a considerable part of the budget. Flooring, tiles, walls, ceilings, interior doors and sanitary fixtures can vary greatly in price depending on the materials selected.
That is why it is not enough to calculate only the cost of the foundation and walls. A realistic budget should include all stages of construction, from the structure and engineering systems to the final finishes and exterior works.
The best way to control costs is to have a well-developed project and a detailed cost estimate before construction begins.
