Air-supported dome
Can create a large enclosure quickly but depends on pressure systems, membrane, anchoring, access and ongoing operation.
International Problem Solvers / Global
There are several covered-sport pathways between an open court and a full conventional building.

Direct answer
Consider air-supported domes, membrane or lightweight clear-span structures, or other project-specific covers based on permanence, climate, clear height, ventilation, operating cost, local approvals and the amount of enclosure required.
Project decision
Use these points to structure the first project conversation. Final suitability stays tied to the actual site, selected system and local project team.
Can create a large enclosure quickly but depends on pressure systems, membrane, anchoring, access and ongoing operation.
Can provide a framed roof and selected wall enclosure without following the same construction logic as a conventional heavy building.
In some climates the real need is rain or sun protection rather than a conditioned hall, which can reduce enclosure complexity.
Project brief
Frequently asked
It can be seasonal or long-term depending on the system and approvals; the operating model is different from a conventional framed building.
Potentially, but foundations, clearances, drainage, court condition and local approvals need review.
There is no universal answer. Structure, foundations, energy, lifecycle, local work and programme all change whole-project cost.
