Can a net adventure be built indoors?

Back to overview

Yes, a net adventure can absolutely be built indoors. As long as the building offers sufficient ceiling height, structural load capacity, and floor space, an indoor net adventure park is fully achievable. The sections below break down exactly what that requires, from structural conditions and suitable building types to safety standards and construction timelines.

What structural requirements does an indoor net adventure need?

An indoor net adventure requires a minimum ceiling height of around 8 to 12 meters, a floor structure capable of handling dynamic point loads, and anchor points that can be fixed to walls, columns, or a steel superstructure. The exact requirements depend on the scale and design of the net adventure, but these three factors determine whether a building is a viable candidate.

Ceiling height is the most immediate constraint. A compelling indoor net adventure needs vertical space to create multiple levels, incorporate slides, and give visitors the sensation of height and freedom. Buildings with less than 8 meters of clear internal height can still host smaller net structures, but they limit the experience significantly.

Load-bearing capacity matters because net adventures distribute weight dynamically across dozens of anchor points. Engineers calculate both static loads (the weight of the structure itself) and dynamic loads (the forces generated by people swinging, jumping, and moving through the nets). These calculations inform whether existing anchor points in the building are sufficient or whether a freestanding steel frame needs to be installed inside.

Floor space requirements vary by concept, but a meaningful indoor net adventure typically needs at least 400 to 600 square meters of usable floor area. This allows for a proper layout with entry and exit points, safety zones beneath the nets, and room for visitor flow.

What types of buildings can host an indoor net adventure?

Industrial halls, sports halls, former warehouses, and large leisure facilities are the most suitable building types for an indoor net adventure park. Any structure with high ceilings, open floor plans, and solid anchor infrastructure can be adapted. Even unconventional spaces like hangars or historic buildings have been used successfully.

The most common choices are:

Industrial and logistics halls – often the best fit due to their height, open spans, and structural steel frames that serve as ready-made anchor points
Sports halls and indoor arenas – frequently used for temporary or semi-permanent installations because they already meet load requirements
Leisure and entertainment centers – purpose-built facilities that integrate a net adventure as one of several attractions
Repurposed retail or commercial spaces – large former department stores or big-box retail units are increasingly converted into indoor adventure parks

The key variable in every case is whether the existing structure can accommodate the anchor loads or whether a freestanding internal frame is needed. A freestanding frame adds cost but removes dependency on the building’s own load capacity, making it a flexible solution for buildings that would otherwise be unsuitable.

How does an indoor net adventure differ from an outdoor one?

The core experience of an indoor net adventure is the same as an outdoor one – multi-level nets, slides, tunnels, and physical challenge – but the environment removes weather dependency and changes the design logic. Indoors, there are no trees to anchor to, no natural landscape to work with, and no seasonal limitations on operation.

Outdoor net adventures typically use trees or purpose-built wooden towers as structural anchors, and the natural setting is part of the experience. Indoor net adventures rely entirely on steel frames or building structures, and the visual atmosphere is created through lighting, color, and design rather than nature.

Operationally, indoor parks have a significant advantage: they run year-round without weather interruptions. This makes revenue forecasting more predictable and visitor numbers more consistent. For operators in regions with harsh winters or unpredictable climates, an indoor net adventure park can outperform an outdoor equivalent in annual visitor volume.

Maintenance considerations also shift indoors. UV degradation of ropes and nets is slower, and exposure to rain, frost, and wind is eliminated. This can extend the lifespan of materials and reduce maintenance frequency, though indoor environments introduce their own considerations, such as humidity control and ventilation.

What safety standards apply to indoor net adventure parks?

Indoor net adventure parks must comply with EN 15567 (for ropes courses and adventure parks) and EN 13814 (for amusement rides and structures), as well as any national regulations in the country of operation. These standards govern structural integrity, anchor load requirements, net specifications, inspection intervals, and operational procedures.

The EN and ISO standards that apply to outdoor adventure parks apply equally to indoor installations. There is no separate indoor standard: the same engineering rigor, load testing, and inspection requirements carry over regardless of whether the park is inside or outside.

In practice, this means:

All anchor points must be tested and certified to handle defined load values
Nets and ropes must meet specific tensile strength and mesh size requirements
The structure must be inspected regularly by a certified inspector
Staff must be trained in operational safety and emergency procedures
Risk assessments must be documented and reviewed periodically

One important note: the building itself must also comply with local fire safety, emergency exit, and occupancy regulations. An indoor adventure park sits at the intersection of amusement structure standards and building regulations, so both sets of requirements apply simultaneously.

How long does it take to build an indoor net adventure?

Building an indoor net adventure typically takes between 3 and 6 months from the start of construction, depending on the size and complexity of the installation. The full project timeline, including design, permitting, and construction, usually runs between 6 and 12 months from the initial brief to opening day.

The timeline breaks down roughly as follows:

Concept and design phase (4 to 8 weeks) – site survey, structural assessment, 3D design, and client approval
Engineering and permitting (4 to 12 weeks) – structural calculations, permit applications, and regulatory review; this phase varies significantly by country and municipality
Manufacturing (6 to 10 weeks) – custom fabrication of steel frames, nets, slides, and components; this often runs in parallel with permitting
On-site construction (3 to 8 weeks) – installation of the steel structure, net system, and all attractions
Inspection and certification (1 to 2 weeks) – third-party safety inspection and sign-off before opening

Delays most often occur during the permitting phase, particularly for buildings being converted from another use. Working with a construction partner who has experience navigating these processes in multiple countries can significantly reduce delays. You can browse completed projects to get a sense of what is achievable within different timelines and budgets.
