It is never easy to estimate a budget to build a house. And for good reason, there are many elements to take into consideration to arrive at an accurate estimate! However, that was without counting this article, which brings together all the useful information for planning a budget to build a house.
How much does it cost to build a 100 m² house?
Budget for building a house by style
As a general rule, a house of style contemporary will cost more to build. The reason ? Quite simply because of the growing interest in modern and contemporary constructions, thus explaining why so-called “traditional” houses are more affordable, due to the fact that they are less popular.
For a traditional house, it is necessary to count, on average, between 1500 and 2100 € per m². Either between 150,000 and €210,000 for an area of 100 m². For a home contemporary, it is then necessary to plan between 2000 and 3000 € per m². Either between 200,000 and €300,000 for an area of 100 m².
Note that it is essential to think carefully and compare multiple quotes, before starting construction work. The services provided by the professionals who will take charge of the project must also be detailed in the estimate. In no case should there be any doubt!
Budget to build a house by type of materials
the materials choice greatly influence the cost of building a house. For example, a container studio or a tiny house whose foundations rest on a pre-built or factory-made structure will generate less construction costs than a house made of bricks or concrete blocks.
For a container studio, it is necessary to count between 900 and 2,200 € per m². Either between 90 000 at €220,000 for an area of 100 m². For a wooden constructionit is necessary to plan between
€1,300 and €2,700 per m². Either between 130,000 at €270,000 for an area of 100 m².
For a brick or block house, the budget must then be revised upwards. It is necessary, in fact, to count between 1,300 to 2,800 € per m² for a construction in bricks and between 1,100 to 2,500 € per m² for a construction in breeze blocks. Or, until 280 000 € for an area of 100 m².
Finally, it is necessary to count, in principle, between 1,400 and 2,500 € per m², for a stone house of size. Either between 140,000 and 250 000 € for an area of 100 m².

Budget to build a house by type of builder
The budget to build a house does not only vary according to the style and the type of materials. It also varies depending on the constructor type !
Thus, if you decide to use your building skills to build your house, the cost price will be lower. Conversely, if you opt for a renowned architectthe cost will be much more expensive.
For a construction called “personal”, it is necessary to plan, in general, 1300 € per m². Is around €130,000 for an area of 100 m². If you entrust your project to a architect, it is necessary to count at least 1,700 € per m². Either, approximately €170,000 for an area of 100 m².
Another possibility is to go through a constructor or one entrepreneur to obtain a turnkey house at an affordable price. It is therefore aimed at intermediate budgets! It is necessary to plan, on average, between 1,400 € and 1,450 € per m². Either between 140,000 and €145,000 for an area of 100 m².
Good to know : it is quite possible to find a cheap architect. It is also good to emphasize that it is mandatory to call on a qualified architect, in the event of a project of more than 150 m².
What are the elements that impact the budget to build a house?
Land price
The price varies not only according to geographic location of the terrain, but also, depending on theground conditions. Thus, flat land that has already been cleared will cost more to buy than bumpy land that has not been cleaned for several years.
Note that the budget to build a house can be strongly impacted by the area of residence. For example, in Provence-Alpes-Côte d’Azur (PACA), a sunny region which is attracting more and more people, it is necessary to count between 5,000 and 6,150 € per m². Either between 500,000 and €615,000 for an area of 100 m².
One-storey or two-storey house?
In principle, a ground floor house is less complicated to build. And for good reason, it is not necessary to add a floor above. Without raising the walls, the construction cost is therefore lower!
Good to know : it is necessary to count, on average, 1,100 € per m² for a house on one level and 1,300 € per m² for a house with one floor.
roof
The framework and the roof also have a cost! For a new roof, the price generally fluctuates between 180 and 250 € per m².

Wall insulation
A construction project inevitably involves thewall insulation. For optimum efficiency, it is preferable to insulate the walls from the outside!
Note that it is necessary to plan between 100 and 190 € per m² for the insulation of the walls from the outside.
Addition of a garage and/or a swimming pool
Adding a garage and/or a swimming pool is not to be taken lightly. And for good reason, this addition will greatly impact the budget to build a house!
Just for a garage, you have to count between 4000 and €30,000. As for an in-ground pool, you must plan for no less than €15,000.
