Why is an outdoor padel court more expensive than an indoor padel court?

An outdoor padel court costs more than an indoor court. That has everything to do with the foundation, the heavier steel structure and the demands that outdoor conditions place on the design. As a guide: an indoor padel court starts from around € 23,000 turnkey, whereas an outdoor padel court including foundation quickly starts from around € 50,000. Want to know why that difference exists and what to look out for? Read on below for exactly what you need to know.

Why is an outdoor padel court more expensive than an indoor court?

An outdoor padel court is more expensive because outdoors you have to deal with factors that simply don't apply indoors: rain, wind, frost, temperature swings and the need to build a solid foundation in the ground. All these factors call for heavier materials, more technical preparation and a more extensive construction process.

With an indoor court you have a protected environment. The floor is already there, the roof keeps the weather out and the structure has to absorb less wind load. With an outdoor court you literally start from zero: the ground has to be prepared, the foundation has to be laid and the steel structure has to withstand years of exposure to wind and weather. That makes the project as a whole more complex and more expensive.

Which parts of an outdoor padel court are more expensive?

The three biggest cost differences between an outdoor and an indoor padel court lie in the foundation, the steel structure and the permit process. Each of these requires a larger investment outdoors than indoors.

• Foundation: With an indoor court the floor is already in place or relatively easy to build. With an outdoor court a full, water-permeable foundation must be built that can withstand precipitation, frost and ground movement. Foundation costs average between € 20,000 and € 40,000, depending on soil conditions and location.
• Steel structure: An outdoor court requires a heavier cage structure that can absorb wind load and is protected against rust and weather. Hot-dip galvanised steel is standard here.
• Permits and studies: Outdoor padel courts almost always require an environmental permit, including an acoustic study, a lighting study and structural calculations. Those costs add up.
• Extra options: Ball catchers, sliding doors and additional fencing are typical for outdoor courts and are rarely used in indoor projects.

Add all these factors together and it's clear why the cost of an outdoor padel court is structurally higher than that of a comparable indoor court.

Why is the foundation of an outdoor padel court more complex?

The foundation of an outdoor padel court is more complex because it has to fulfil several functions at once: it must carry the weight of the steel structure, absorb wind forces, drain rainwater and resist frost damage. No two locations are the same, so custom work is always needed.

There are three commonly used foundation types for outdoor padel courts, each with its own characteristics:

• Drainage concrete: A water-permeable concrete floor where rainwater drains straight through the foundation into the soil. Drainage concrete has an average lifespan of 25 to 40 years and is one of the most widely used solutions for outdoor courts. It is often combined with a ring foundation to distribute the forces of the steel structure properly.
• Supersub: An innovative solution based on foam concrete. Supersub is lightweight, self-levelling and water-permeable. It can handle up to 500 mm of rainfall per hour and is shock-absorbing, which contributes to playing comfort. For new builds the thickness is around 15 cm, depending on soil conditions.
• ZOAB asphalt: A porous type of asphalt that lets water through. Less common for padel, but in certain situations a good option.

Which foundation type is most suitable depends on the soil conditions, the wind zone, the accessibility of the location and the available budget. Before construction, cone penetration tests are carried out to assess the subsoil.

Without that analysis you risk subsidence or tilting in the long term. All foundation materials used in the Netherlands must be approved by Kiwa ISA Sport. That is not a formality: it protects you as a buyer against materials that do not meet the applicable standards for competition use.

What is the difference in steel structure between outdoor and indoor courts?

The steel structure of an outdoor padel court must be heavier than that of an indoor court, because it is directly exposed to wind, rain, sun and temperature swings. That calls for different material choices, heavier profiles and a protective coating.

With an indoor court the wind load is negligible and the structure does not have to offer protection against the weather. The steel structure can therefore be dimensioned lighter, which keeps costs down.

Different requirements apply to an outdoor court:

• Hot-dip galvanised steel: This is the standard protection against rust and oxidation on outdoor courts. The galvanising process creates a durable coating that lasts for years without major maintenance.
• Heavier profiles: The posts, beams and connections are dimensioned for the wind load at the specific location. An open site or coastal location calls for a heavier design than a sheltered, inner-city spot.
• Structural calculation per location: Every outdoor court requires a specific calculation based on the wind zone, the surrounding buildings and any extra elements, such as sound-absorbing panels. Panels reduce the wind permeability of the cage, so the structure absorbs extra wind load and has to be structurally reinforced.

All this makes the steel structure of an outdoor court more expensive not only in materials, but also in engineering and production.

How much does an outdoor padel court cost on average in the Netherlands?

As a guide, an outdoor padel court in the Netherlands starts from around € 30,000 excluding foundation and from around € 50,000 per court including foundation. The exact price always depends on the location, the soil conditions, the chosen foundation type and any extra options.

That range is wide, and not without reason. The foundation is the biggest variable: foundation costs can range between € 20,000 and € 40,000, depending on soil conditions, the accessibility of the location and the civil works required. At locations with an existing tennis court, part of the substructure can sometimes be reused, which can reduce costs considerably.

Besides the court itself, there are optional cost items that regularly come up in outdoor projects:

• Ball catchers: around € 1,200 per side
• Sliding doors (lockable)
• Sound-absorbing panels (price depends on location and size)
• Additional fencing or screening

If you compare this with the cost of an indoor padel court, you will see that the price difference is not in the cage structure itself, but in everything around it. Always request a tailor-made quote based on your location, because quoting a fixed price without that context gives a distorted picture.

When is an outdoor padel court the right choice after all?

An outdoor padel court is the right choice when you have no indoor space available, when your location offers enough outdoor space and when the investment fits the intended use and the operation. For many tennis clubs and municipalities, building outdoors is the only realistic option.

There are situations in which an outdoor court is clearly preferable:

• Existing tennis facilities: Clubs that want to convert tennis courts into padel courts almost always do so outdoors. The existing infrastructure, the site and the surroundings are already suited to it.
• Locations without an available hall: Municipalities or operators with a piece of land available but no covered space logically opt for an outdoor solution.
• Seasonal use: When the location is mainly used in the summer months, the higher investment weighs less heavily against the revenue.
• Combination with outdoor hospitality or recreation: An outdoor court fits well in a recreational setting where the outdoor feeling is part of the experience.

Keep in mind that outdoor courts require an environmental permit and that an acoustic study is almost always mandatory. The processing time for a permit application averages 8 to 12 weeks. Factor that into your timeline so you don't run into surprises.

How do you save on the cost of an outdoor padel court?

You can save on the cost of an outdoor padel court by making smart use of existing infrastructure, choosing the right foundation type for your situation and building several courts at once. Economies of scale and good preparation are the two biggest cost-saving factors.

Concrete ways to keep costs under control:

• Reuse of existing substructure: Do you have an existing tennis court? Then part of the substructure can sometimes be reused as the base for the new foundation. That saves considerably on civil costs.
• Several courts at once: When building two or more courts, economies of scale arise in production, transport and installation. The cost per court drops noticeably as a result.
• Choose the right foundation type: Drainage concrete, Supersub and ZOAB asphalt each have a different price-quality ratio and a different suitability per soil type. Good foundation advice based on cone penetration tests prevents you from spending more than necessary.
• Start the permit application early: Delays in the permit process cost time and, indirectly, money. Start the process as early as possible, so that construction can begin as soon as the permit is in.
• Use noise solutions smartly: Sound-absorbing panels on one side of the court are cheaper than a full noise barrier. In many situations that is enough to meet the noise standards and achieve more playing hours.

Finally: don't compare on price alone. A cheaper supplier who works with non-certified materials can end up costing you dearly later. In the Netherlands, all foundation components must be approved by Kiwa ISA Sport. If you work with a party that cannot demonstrate this, you risk the court not being approved for competition use by the KNLTB.
