The House Foundation Cost Estimation Details in 2025

It is commonly known that the foundation of a house is a crucial element that supports the entire structure. To create a stable, sturdy, and functional foundation, it is not enough to only consider the quality of the materials. You must also carefully calculate the cost of the foundation

In fact, the cost of a house foundation cannot be generalized for all projects. Many factors influence it, including the type of materials used, the soil conditions at the construction site, the accessibility of the location, and the type of foundation chosen.

If you are planning to build a house and need information about the estimated cost of a house foundation, read the explanation below thoroughly!

What Is a Foundation?

A foundation is a building structure located at the very bottom and in direct contact with the ground. Foundations are key to the stability and sturdiness of all types of buildings, including residential houses.

Foundations are built to serve several functions, including transferring the load from all parts of the building into the ground and withstanding lateral loads, such as ground movement and wind pressure. Additionally, they help manage groundwater pressure, especially in buildings located in areas with high groundwater levels.

Foundations also contribute to increasing the resilience of buildings during natural disasters, such as floods and earthquakes. A stable foundation can be the main support that ensures the integrity of the building structure.

One issue to be aware of is the various types of deterioration that can occur in different parts of a building, such as cracked walls and uneven floors. This is where the building's foundation plays a crucial role in preventing such problems.

Given its vital role, a strong foundation is necessary to ensure the long-term stability of a building. The following are some characteristics of a strong house foundation:

Made from high-quality materials so that it can function as intended for its estimated lifetime.
Adapted to local soil conditions.
Be able to withstand the loads above it, including construction loads, live loads, wind loads, earthquake loads, and various other types of loads. This is important to prevent building subsidence, cracks, and collapse.
Resistant to various types of organisms and exposure to dangerous chemicals.
If reinforcing bars are used, they are covered with a thick layer of concrete to prevent rusting.
Safety elements have been added to prevent collapse if the structure is expanded with loads beyond what was planned.

Estimated House Foundation Costs

The way to calculate the cost of a house foundation is to consider two equally important factors, namely material costs and labor costs. The following are the estimated costs of a house foundation for each of these purposes:

1. Material Costs

It is best not to be easily tempted by low prices under the pretext of reducing costs, but to choose good quality materials that can optimally support the strength of the structure.

If you only rely on low prices, you may end up spending much more on repairs in the future.

Material prices may vary from region to region. However, below is an estimate of the material costs for building a house foundation in general:

Fill sand costs Rp185,000 per cubic meter.
Masonry sand costs Rp245,000 per cubic meter.
Crushed stone costs Rp810,000 per cubic meter.
Cement costs Rp60,000 per bag.

2. Foundation Costs

To calculate the foundation requirements for a one-story house, you can use the trapezoid volume formula. For example, if the bottom width is 50 cm, the top width is 30 cm, and the height is 60 cm, the volume is ((0.5 m + 0.3 m) / 2) × 0.6 m = 0.24 cubic meters.

Thus, each meter of foundation length requires 0.24 cubic meters of material. If the cost per cubic meter for building a 5×10 meter house is Rp1.2 million, then the foundation cost per meter is around Rp288,000 (Rp1.2 million × 0.24 m³).

Since the planned house has an area of 50 square meters, the estimated total cost for the foundation is:

Rp288,000 × 50 meters = Rp14,400,000.

3. Worker Wages

Generally, you will need four workers to build the foundation of a house. These workers consist of a foreman, a head worker, pieceworkers, and construction workers. The following is an estimate of the costs you need to prepare for the salaries of these workers:

Foreman: Rp90,000 wage per day.
The head worker: Rp100,000 wage per day.
The pieceworkers: Rp90,000 wage per day.
The construction workers: Rp85,000 wage per day.

House Foundation Construction Costs Based on Its Type

After knowing the estimated cost of materials and labor to build a house foundation, it is time for you to know the estimated cost of the foundation based on the type of house. Below is the estimation:

1. Minimalist House With 36 Square Meters Area

A minimalist house with an area of 36 square meters, commonly known as a type 36 house, is often the preferred choice of young couples or small families with one child. This house typically has 2 bedrooms, 1 bathroom, and other essential rooms.

If you plan to build a minimalist house measuring 36 square meters, prepare a budget of Rp2,600,000 per square meter. Therefore, the total cost of a simple house foundation, excluding the cost of purchasing the land, is Rp90,000,000.

2. Minimalist House With 150 Square Meters Area

Constructing this type of house generally costs around Rp2,500,000 per square meter. You also need to prepare a budget for workers' salaries of around Rp130,000 per person. In total, the cost of building this type of house is around Rp375,000,000.

3. Modern House With 300 Square Meters Area

This type of house is usually built with 2 floors and 4-6 bedrooms. The estimated cost of the foundation for a 2-story house with an area of 300 square meters is around Rp4,000,000 per square meter, so the total construction cost is around Rp1,200,000,000.

4. House With 40 Square Meters on 84 Square Meters of Land

Furthermore, if you plan to build this type of house, you should know that the price of the land is around Rp1,200,000 per square meter. The construction cost is around Rp2,900,000 per square meter.

From the information above, the total cost you need to prepare is approximately Rp100,800,000 for the land and Rp116,000,000 for constructing a house of 40 square meters.

That concludes the explanation of the costs of the house foundation and some essential tips you need to understand about a strong foundation. Carefully calculating the costs and considering other important factors are the first steps toward ensuring the best possible foundation quality.
