Do you need a permit for an extension? - Permit

In principle, you can build an extension without a permit up to 4 meters. However, if your house is located in a protected urban landscape, if it is a municipal or national monument, or if your municipality has regulations on this matter, you will need to apply for a permit.

The floor consists of a prefab-insulated system floor with an insulation value of Rc 4.5 m².K/W. The walls of the extension are made of a steel skeleton frame, with an insulation value of Rc 4.9 m².K/W. The roof consists of a steel beam layer with an insulation value of Rc 6.0 m².K/W.

Of course, we are not impartial. But when you look at the objective advantages and the results, the quality is at least the same, if not better. This is due to various factors, including the fact that the construction is done indoors under perfect conditions, as there are no weather-related disruptions. Additionally, work is done on a clean and flat floor. The attachment process is the same as traditional building methods. That is why we confidently offer the guarantee that the ready-made extension is of at least the same quality.

A prefab extension is not produced on the construction site, but is fully manufactured in the workshop. Construction takes place in a calm environment under perfect conditions, which offers many possibilities. Nearly all types and kinds of buildings can be made prefab. Other important differences are experienced during the construction period itself. For example, you and your neighbors will experience much less (noise) disturbance. Most of the work takes place not at your home, but in the workshop. Additionally, the quality of prefab construction is always guaranteed because the construction conditions are ideal. A further advantage is that more attention is given to the details beforehand, as everything must be made before the construction starts. This helps eliminate potential construction errors early on, which would otherwise only become apparent later. In short, there are quite a few advantages.

If there is an existing extension, it is possible for us to build next to the existing extension. The only thing that cannot be done is building on the existing floor. In that case, we first need to demolish the existing floor.

With regular maintenance, your extension is on par with a regular house.

After measuring/drawing the extension, it will become clear if it’s possible to have the walls/ceiling run smoothly. In a terraced house, the walls always come inward.

The tiles must be removed from the width and depth of the extension so that the extension can be completed in 5 days. The tiles and excavated soil can be placed in « big bags, » at least 4 meters from the back wall. On the lifting day, these will be taken from the garden and placed in containers.
