4 common mistakes when building a padel court in an existing hall

At first glance, an existing hall seems an ideal starting point for building a padel court. The space is already there, the roof is on and the location is known. Yet in practice we regularly see projects in existing halls turn out more expensive, slower or more complicated than expected.

Not because building padel is so complex, but because a number of common mistakes only come to light once construction has already started. In this article we list the four most common mistakes, so you can avoid them.

What makes an existing hall uniquely challenging for padel

An existing hall has fixed characteristics that you cannot change: the height is what it is, the floor is already there and the acoustics are determined by the construction. With a new build, you can set up all of these factors for padel in advance. In an existing hall you adapt your plans to what is already there, and that calls for an accurate assessment up front.

The challenge is not only technical. Planning, permits and acoustics also play a role that works out differently in existing halls than in new builds. Anyone who underestimates these factors risks remedial work afterwards, delays or extra costs that could have been avoided. The four mistakes below are the most common when building a padel court in an existing hall.

1: Underestimating the clear height

The minimum recommended clear height for an indoor padel court is 6 metres. That sounds more than sufficient in a sports hall, but in practice there are more obstacles than the height on paper suggests. Think of roof trusses, light fittings, sprinkler systems, ventilation ducts and other technical installations that limit the free playing space.

The mistake made most often here: the height is measured at the highest point of the hall, not at the spot where the court will actually stand. A hall that is 8 metres high in the centre may have only 5.5 metres of clearance at the sides or under a truss. That is too low for a full-size padel court and leads to discussions about the layout of the hall or to modifications that were not budgeted in advance.

Always have the clear height measured at the exact location of each court, including the position of all installations present. It is a small step that prevents big surprises. For professional use, the rule is also: the more space above 6 metres, the better the playing quality.

2: Not having the floor assessed

The floor of an existing hall rarely seems like a problem. It is there, it is flat and it feels solid. Yet a floor inspection is one of the most frequently skipped steps when building a padel court in an existing hall, and it regularly leads to problems.

A padel court places specific demands on the subbase. The steel structure and glass walls bring point loads that differ from the distributed load of a standard sports floor. If the existing floor has not been calculated for those loads, or if there are invisible cracks, subsidence or moisture problems, this can lead to damage to both the floor and the structure after construction.

In addition, the floor must be flat enough for a consistent ball bounce. A height difference of a few millimetres over the length of the court is already noticeable in play. Always have the floor assessed by a specialist before construction starts. In some cases a levelling layer or local repair is needed, and it is much cheaper to know that before the steel structure is up than after.

3: Ignoring noise requirements until it is too late

Padel produces more noise than most people estimate in advance. The ball hitting glass and steel, amplified by the cage structure acting as a resonance box, results in an average sound power level of approximately 91 dB. That is roughly 10 dB more than tennis. In an enclosed hall, that sound bounces back from the walls and roof, which further increases the noise load for local residents.

The mistake made here: noise requirements are seen as a permit matter that will be sorted out later. In practice, however, noise requirements determine the construction of the court itself. Sound-absorbing panels are attached to the outside of the cage structure and change the wind exposure of the structure.

That means the steel structure must be reinforced to meet the extra wind load. Anyone who wants to add this afterwards to a standard court that has already been installed runs into high modification costs or discovers that it is simply not possible without replacing the court.

So map out noise requirements early in the process. Check whether the municipality sets acoustic requirements, check whether there are residential buildings nearby and have the acoustic situation assessed before the structure is designed. That way you avoid being faced with an unsolvable problem afterwards.

4: Choosing a standard court in a custom situation

An existing hall is rarely a blank sheet. There are columns, deviating dimensions, existing installations and sometimes a floor that does not line up exactly with the standard position of a court. Yet many customers opt for a standard court that is delivered as it is produced, without adaptation to the location.

That works in a new-build hall designed specifically for padel. In an existing hall it leads to compromises: courts that just do not fit, run-off zones that are shortened, lighting that does not hang optimally or structures that do not match the specific load of the location. Every location faces different conditions, such as wind load, soil conditions and spatial constraints, and a standard court takes none of that into account.

The solution is a structural calculation per location. The steel structure is then adapted to the specific requirements of the site, not the other way around. This is particularly important for deviating dimensions, noise solutions and locations with special structural requirements. A tailor-made quotation for an indoor padel court always starts with a site assessment, not with a standard price list.

How to prevent costly remedial work afterwards

The four mistakes above have one common cause: decisions are made on the basis of assumptions rather than a thorough assessment of the location. Remedial work afterwards is always more expensive than good preparation up front. A few concrete steps that make the difference:

• Have the clear height measured at the exact position of each court, including obstacles.
• Have the existing floor assessed for load-bearing capacity, flatness and moisture condition.
• Map out noise requirements early and incorporate them into the structural design.
• Choose a provider that calculates and adapts the structure per location.
• Always ask for a structural calculation as part of the quotation.

Good preparation takes time, but saves considerably on the total project cost. Anyone who skips these steps in order to start sooner risks delays and extra costs that more than cancel out the time advantage.

How I-Padel helps with building a padel court in an existing hall

We understand that an existing hall poses different challenges than a new-build project. That is why we always start with a site assessment, so that we know exactly what conditions we are dealing with. What we offer:

• Structural calculation per location, tailored to the specific requirements of your hall.
• Assessment of the existing floor and advice on any modifications.
• Integration of sound-absorbing panels in the structural design, including the necessary reinforcement of the steel structure.
• Custom solutions for dimensions, layout and technical installations within the hall.
• A fully turnkey process from advice to completion, including artificial turf, LED lighting and glass.
• 15-year warranty on the steel structure, which we manufacture entirely in-house.
