LDD-04 · West Gym Hero Wall (Clerestory)
One-line intent
A protected center with a disciplined daylight crown — basketball dominates, light supports.Adjacent functional walls (per builder drawings, added 2026-05-15)
The gym is bounded on its short ends by two purpose-built interior walls that coordinate with this hero wall:
- Ballet wall (north end, between gym and ILS) — likely mirrored / barre-equipped surface for stretching, ballet, warm-up.
- Rebound wall (south end, between gym and south bay) — designed for ball-rebound practice (basketball, soccer drills).
These confirm the gym is intended as a multi-sport athletic training environment, not just a basketball half-court. The west hero wall should not visually compete with these working surfaces.
Locked decisions
- Composition: center field = basketball (no glazing) · upper field = daylight crown
- Clerestory: two rows × 24" each (~48" total height)
- Modules: 16' runs subdivided into 4' sub-modules
- Center no-glazing field: ~12' wide (72" backboard + 3' buffer each side)
- Perfect symmetry left/right of center
- Clerestory bottom above active play zone
Prohibited
- Glass behind hoop
- Irregular modules
- Oversized spans
- Anything that puts daylight system in competition with play surface
Open items / engineer review
- Final glass spec (laminated, Low-E, U-value)
- Solar gain + glare strategy — west-facing 48" of clerestory in summer afternoon will cook the gym
- East wall equivalent? LDD set is silent on east elevation
- Rain-screen detail at clerestory head/sill on metal IMP wall
- Backboard retraction kinematics must clear clerestory
Cost drivers
Clerestory glass + frame ~190 sqft × $100–160/sqft = $20–30K. Backboard + hoop $8–14K (LDD-22). Shading strategy if needed $5–12K. Total west wall: $55–90K.Air-gap concerns
- West-facing solar gain is the killer. 190 sqft of west glass = serious afternoon heat load. Mini-splits + radiant slab won't easily handle it. Manual J + shading strategy mandatory.
- Glare on the court in late afternoon. Frit pattern, exterior screen, or motorized interior shades — all add cost.
- Backboard retraction must clear clerestory mullions + glazing.
- Mini-splits + destrat fans visible from gym side coordinate with the disciplined hero wall.
