About building construction costs

In the calculation of construction costs, expressions such as the unit price per tsubo "¥ ~ / tsubo" are often used, but this is not very reliable. No matter how small the floor area is, the toilet and bathroom will not disappear, so the construction cost cannot be determined by the area alone. It depends on the purpose of the building, the structure, the site conditions, the times, the level of the construction company, and of course the content of the design. The only way to get an actual price is to get a quote, but first let's take a look at the budget planning outline on this page. After that, we will guide you through the budget plan for building a house step by step, so please apply it to yourself and try it. At the end of the page, the prices of the buildings that Jam's worked on are listed only if the owner has given permission, so please use them as a reference.

Know how much you can spend on construction costs!

First of all, borrowing simulation on the homepage etc.

First, let's grasp the overall budget. I think most people use a mortgage, but you can simulate the amount you can borrow from your own funds, income, monthly desired repayment amount, etc. at an institution that provides loans such as a bank homepage. If you are self-employed or already borrowed, it is wise to consult at the counter first.

Overall Budget-Necessary Expenses

= Construction cost

Now that you know the overall budget, let's figure out the necessary expenses other than construction.

Below is a list of commonly required items. Unfortunately, depending on the case, some may or may not be needed, and others may be needed. Of course, there are differences in the amount of each item, so please contact us for details.

The budget obtained by subtracting these costs from the total budget is the budget for construction costs. ..
