Adding an extra floor on a flat roof is an excellent way to create more living space. But these types of projects also entail various constructive challenges. A construction calculation is important to guarantee the stability of your home and to prevent surprises. Read on and discover what you should take into account!
What construction risks are there?
An extra floor means extra weight and load on your existing structure. If the current foundation, walls or roof structure cannot cope with this, it can lead to serious problems such as:
- Subsidence of the house.
- Cracks in walls or ceilings.
- In the worst case, even a risk of collapse.
In addition, a higher home causes a change in wind loads, which affects the stability of the building. Without a construction calculation, you do not know whether your home can handle this new load, and you run the risk of high repair costs or safety problems.
How does a construction calculation help your project?
A construction calculation is the key to a safe and successful extra floor on a flat roof. This calculation ensures that all constructive challenges are identified and that your project meets the legal requirements.
What exactly is being analyzed?
- The load-bearing capacity of the existing walls and foundation: Is reinforcement needed?
- The extra load due to the new floor: Can the roof support the weight?
- Wind load and stability: How does the structure remain sturdy in strong winds?
With these insights you can prevent structural problems and create a secure basis for your project.
What makes an extra floor a sustainable investment?
Placing an extra floor on a flat roof can not only provide more living space (on average 20 to 30 m²), but it can also be a sustainable investment in other ways:
- Higher home value: A larger home often means a better resale value.
- Energy savings: High-quality insulation and subsequent insulation of the existing roof saves energy.
- Enabling a green roof: Consider a green roof for additional insulation and climate benefits.
With the right preparation and a construction calculation, you get the most out of your investment.
Is applying for a permit mandatory?
An extra floor on a flat roof almost always requires a permit. A construction calculation is a mandatory part of the permit application. This shows that your project meets all safety standards and building regulations.
The municipality uses the calculation to assess whether your home is suitable for the extra floor. Without this step you may experience delays or even risk rejection of your application.
