If you want to know exactly how much your house will cost from the beginning to the end of construction, it will not be superfluous to contact specialized companies to compile the corresponding estimates, which will be included, mainly the price of the foundation. For greater confidence, another 15-20 percent of the cost for securement can be added to the compiled estimate. Only after this can construction can begin, absolutely not fearing that your budget is not enough and the process will have to be suspended. The price of the foundation, of course, is a considerable share of the total construction price, since this design uses, as a rule, a large number of fairly expensive materials, and labor costs for the construction of a high -quality underground structure are usually considerable.
