The building permit, the structural work to put the house out of air and water, the finishing work as well as the finishes: how long does it take to build a new house? From applying for a loan to delivering your new home, it takes an average of 9 to 12 months . But this period may be extended depending on your land, construction plans, climatic hazards, etc. We offer you a complete guide to the different stages of construction of a new house in order to help you estimate as precisely as possible the time required for the construction of your future home.

The preliminary stages of construction work

Before starting the shell, you will have to go through several stages essential to your construction project which must be taken into account in the calculation of the overall duration of the construction work of your home.

The financing of the project thanks to the mortgage

This is indeed the starting point of your project: complete your mortgage application file to set up financing. Your home builder can help you prepare for your credit application and also direct you to help that can lower the price of your project. The time taken to obtain a mortgage can vary between 15 days and 1.5 months. You will then have a minimum of 10 days to respond to this loan offer.

From the choice of land to the building permit

Finding the ideal land can take several weeks, depending on your criteria or the local market. During your research, you must take into account the orientation of the land, but also the PLU, or Local Urban Plan, to ensure the feasibility of the construction. When you own the land, your home builder, or architect, performs for you the plan of the house. Provide for this a period of between 1 month and 3 months of work. Then comes the time to delimit the land, an action carried out in one day, often involving residential fence companies to mark property boundaries clearly and professionally.

Finally, and before starting the structural work, you will enter the building permit phase: it can last 2 months until it has been approved by the town hall. It is also during this stage that you will be able to sign a Contract for the Construction of an Individual House, or CCMI , a contract that protects you with regard to the construction, its price and its delivery time. Regarding the overall budget, builders can provide you with information on the amount of the various taxes inherent in a new construction, including the development tax.

The duration of the various stages of structural work

The shell really corresponds to the launch of the site of your construction. Different trades will take turns to carry out this initial work, in accordance with the established construction plan:

The excavation of the soil . Count from 1 day to 1 week with however a significant risk of delay depending on the weather. Indeed, earthworks can only be done on dry ground. Depending on the weather conditions, this first part of the work may therefore be extended.

Soil drainage. Depending on the type of soil, draining the land can take from 1 day to 1 week .

The foundations are carried out by a professional provided that the excavations are dry. The weather can therefore intervene and change the normal deadline set between 1 day and 1 week.

The walls. This is the base for which you will have to allow a period of 2 to 6 weeks.

The paving makes it possible to isolate the slab, to cover it with a screed to deposit, later in the course of the work, the floor coverings.

The setting out of water and the setting out of air constitute the last two phases of the shell of the construction of a house. The insulation of the roof, the installation of the framework, windows and doors are works which extend over a period of 4 to 8 months .

The finishing work for the construction of a house

Once the shell is finished, the house is said to be out of air and out of water . This is the signal to start the second stage: the finishing work. This work, which involves professionals from several trades, is spread over several weeks . Indeed, the duration of this finishing work varies according to the surface of the house and the construction plans. Here are the main steps:

How long does it take to finish a house?
