HeroX Air Domes

Paris, France — Le Rancy Tennis Club merged its dome directly into the existing clubhouse.

No detached structure. No external transition. The membrane integrates with the building, so members walk straight from the lobby onto a covered court.

1,225 m². 35 × 35 × 13m. Built 2025.

Everyone talks $/sq ft. Owners care about $/booked court-hour.

Tennis math (per court):
— 16 hours of bookable time per day
— 350 operating days per year
— $40 average court-hour rate
= ~$224,000 per court, per year — at 100% utilization.

Most operators hit 70–85%. So plan for $155K–$190K per court, per year.

Now multiply by your court count. That's your revenue ceiling. The dome is the unlock.

Air dome or fabric structure? Quick decision guide.

Air dome: $15–25/sq ft upfront, higher operating cost, fully relocatable, fastest to install.
Fabric structure (steel/aluminum frame): $25–55/sq ft upfront, lower operating cost, permanent feel, better for industrial.

Sports facility with seasonal flex? Air dome.
Hangar, warehouse, mining cover? Fabric.

Our first transparent air dome lives in Loughborough, UK — and the light pours in.

Natural daylight cuts lighting costs. Fewer electricity hours. Better visibility for players. A facility that doesn't feel like a tunnel.

Royal Astrid Club, Belgium — a tennis dome with a magic trick.

In summer, the courts are open-air. In winter, the dome rises — and the anchoring rings disappear, hidden flush in the concrete when not in use.

Custom retractable anchoring. No compromise between summer aesthetics and winter revenue.

"Quality and efficiency. Availability of the team. Respect of the delays. The dome is high quality with an incredible result when we are inside."
— Yacine, Royal Astrid Club

"What does an air dome actually cost?" The honest answer.

The dome itself: $15–$30 per sq ft.
Smaller domes sit closer to $25–30/sq ft. Larger domes drop to $15–20/sq ft (economies of scale).

Total project cost: roughly 2–3× the dome price. Add foundation ($400–500/linear ft of grade beam), permits, engineering, utilities, and install.

Example: a 10,000 sq ft tennis dome runs about $200K for the dome and $400–600K all-in.

Madison, Connecticut: a 6-lane swimming pool now generates $70,000/month of year-round revenue.

Before the HeroX dome: outdoor pool, roughly 5 months of usable season.
After: 12 months of swim school, lap memberships, lessons, and lane rentals.
Projected ROI: 2.5–3 years.

"The air dome has been a game-changer. It allows us to keep our doors open year-round and maintain multiple revenue streams. HeroX was easy to work with, delivered on time, and provided a top-quality structure at a competitive price."
— Rick Fay, Madison Racquet & Swim Club
