What does turnkey construction include?

DEA Immo builds your turnkey house in Belgium and accompanies you during all the key stages of the construction of your home.


Site preparation

Depending on the condition of your land, we will have to make various preparations and adjustments before starting the work.

This may concern your land: the removal of existing vegetation, the levelling of the land or the preparation of the work (installation of the site fence, access for trucks and workers,...).



A solid foundation is essential to ensure the stability and durability of the construction. The first step will be to analyze your soil and its characteristics. This will allow us to dig the hole of the size and depth necessary to support the structure.

Then our experts will grade and compact the bottom to form a solid and stable base on which the foundations can be laid. Depending on your soil type, your foundations will be made of steel or concrete.

Now that your foundations are laid, we will insulate the structure to avoid heat loss and moisture problems. We will also provide a drainage system around the foundation.


Masonry, carpentry & roofing

The next steps will be the construction of the load-bearing walls, the laying of the framework and the laying of the roof, which are part of the structural work.

The load-bearing walls support the structure of the building and allow the loads to be distributed throughout the construction. There are different types of load-bearing walls, including concrete block walls, brick walls, stone walls, timber walls, etc.

Once we have completed the construction of the load-bearing walls, we will be able to install the framework and the roof of your building. Again, several materials can be used depending on the constraints and needs of your project. Trust our team of experts to deliver the most suitable solutions for your structure.


Secondary works & finishing

Finishing work includes all the finishing work needed to make the building habitable, such as insulation, laying floor and wall coverings, installing doors and windows, fitting sanitary fittings, and installing heating, ventilation and electrical systems. This includes insulation, laying floor and wall coverings, installing doors and windows, fitting sanitary equipment, installing heating, ventilation and electrical systems, etc.

This work is numerous and will take up most of your site. For each speciality, we have a dedicated team of experts. Among our 60 employees, we have expert electricians, carpenters, plumbers, heating engineers, plasterers, etc. to ensure the highest quality of our installations.


Handing over the keys

The work is finished and your house is ready to welcome you. Our team of experts, your site manager and your architect meet again to ensure that all the work has been carried out according to the specifications and plans.

This is followed by the provisional acceptance period, once you have moved into your home. At least one year later, the final acceptance takes place and marks your complete satisfaction with the project.
