The concise answer

Squash center design is the engineering of regulation squash courts and the club facilities around them. It covers exact court geometry and wall/floor systems, structural design for glass viewing walls, contained acoustics, and the draft-free HVAC and glare-free lighting the enclosed game demands.\n\nThe court is a precision instrument. Every dimension, every surface, and every environmental condition affects play — which means the engineering tolerances are tighter than in almost any other sports building. The structural engineer, the court system supplier, and the MEP engineer have to work from the same dimensional truth, because a wall that's an inch off or a diffuser that drafts is a court players complain about forever.

Where the engineering actually lives

The wall and floor systems are the sport-specific engineering: walls finished for true, consistent ball response (plaster or panel systems with no dead spots), floors of maple or synthetic with the right resilience, and the tin and out lines at exact heights. These are supplied as systems, but the building has to receive them — the structural slab must be flat and level, the walls plumb, and the dimensions verified before the court contractor arrives.\n\nLighting and climate are the MEP core. Courts need 50-plus footcandles, perfectly even, with fixtures that don't glare in players' eyes when they look up — usually indirect or well-diffused sources. The HVAC handles the intense small-box loads with quiet equipment (a roaring air handler next to a court ruins the acoustic environment) and humidity control that protects wood floors and keeps the air breathable at full exertion.

What I push for on day one

Squash centers are small buildings where every inch and every decibel matters. The engineering has to be exact because the players are.\n\nHere's my checklist.

Build the dimensional truth first: court dimensions drive structure, and every layer counts
Engineer glass walls as structures: impact loads, frame stiffness, and base detailing
Design HVAC for the sealed box: high load, low velocity, quiet equipment, real dehumidification
Contain the sound: box-within-a-box where needed, sealed doors, flanking-path control
Light the white box evenly: 50-plus footcandles, no glare, no shadows in the corners
Verify before the court contractor arrives: slab flatness, wall plumb, dimensions as built

What else do project teams ask?

What are the exact dimensions of a squash court?

A regulation singles court is 32 feet long by 21 feet wide, with a 15-foot front wall (for softball; hardball courts differ slightly) — and the tolerances are tight because the game is played off the walls. The engineering has to deliver those dimensions as built, which means the structural and court-system design accounts for every layer: wall panels, finishes, and the floor system all eat into the clear dimensions.

How are glass squash court walls engineered?

Glass back walls (and increasingly glass side walls) use tempered laminated glass panels in structural frames, engineered for ball impact loads, player impact, and the thermal and structural movement of the building. The framing has to be stiff enough that the glass doesn't flex distractingly, and the base channels need drainage and impact protection. It's a small structural system with outsized importance — the glass is the viewing experience.

Why is HVAC tricky in a squash court?

The court is a small sealed box with two athletes at maximum exertion — the heat and humidity load per cubic foot is extreme — but supply air can't create drafts that affect the ball. The design uses low-velocity supply, often from high diffusers aimed away from play, with generous exhaust and dehumidification. Get it wrong and the court is either a sauna or the ball moves strangely; there's no middle ground players accept.

How do you keep squash noise contained?

With the court built as a box-within-a-box where needed: isolated wall and floor systems, sealed doors (acoustic seals on a door players slam matter), and absorptive treatment in corridors and adjacent spaces. The ball impact is sharp and repetitive, so flanking paths — structure-borne sound traveling through the building frame — get as much attention as the walls themselves.
