Find out how large the stairwell should be in the calculation

Installing a stairwell may seem like a simple job. However, it is important to take the stability and safety of your home into account. Constructiefgoed is a specialist in construction calculations. We ensure that your stairwell meets all building regulations and is installed safely. In this article we explain why a construction calculation is important and how we can help you determine how large a stairwell should be.

Why a construction calculation is important for your stairwell

A stairwell has more influence on the construction of a home than you might initially think. Cutting an opening in the floor changes the supporting structure. A construction calculation is necessary to determine whether the building remains safe after installing a stairwell.

When making a construction calculation, the constructor examines the supporting structure of the house. This calculates how the weight of the floor and other loads, such as furniture, is carried by the floor slabs. This analysis prevents the stairwell from endangering the stability of your home. This makes a construction calculation indispensable.

How big should your stairwell be?

The question “how big should a stairwell be?” depends on several factors. A stairwell must be large enough to allow comfortable use of the stairs. At the same time, it should not weaken the supporting structure of the home too much.

A construction calculation takes into account:

• The height from the floor to the ceiling. This determines the number of steps on the stairs.
• The width of the stairs, which determines the minimum dimensions of the stairwell.
• Any safety standards that apply, such as the Building Decree.

With this information, a designer can determine exactly how large your stairwell should be and where it can be placed.

Safety comes first

A stairwell in a concrete floor or load-bearing structure needs extra attention. Without proper support, the floor can sag or even collapse. A construction calculation identifies this risk.

If additional support is needed, such as a U-beam, this is included in the calculation. This beam distributes the forces of the stairwell over the adjacent floor slabs. This prevents subsidence and ensures that the home remains safe.

When is a construction calculation mandatory?

A construction calculation is not only important for safety. In many cases it is also mandatory. This applies, for example, to:

1. Stairwells in concrete floors.
2. Monumental buildings, where every adjustment must comply with strict rules.
3. Situations where a building permit is required.

The municipality checks the safety of your renovation based on the construction calculation. Without this calculation you run the risk of the permit being rejected.
