LOCKED geometry
tied to LDD-07 vent risk
LDD-20 · Primary Social Counter
One-line intent
A performance-driven social system — not a kitchen island, an event surface for shared cooking.
Locked decisions
| Dim | Value |
|---|
| Length | ~14' |
| Depth | ~42" (deeper than typical 24–36") |
| Height | ~36" (standard counter height) |
Three-zone zoning
| Zone | Function |
|---|
| Left | Clean, visual connection to gym |
| Center | Korean BBQ — main feature |
| Right | Induction support cooking |
Ventilation + seam strategy
- Lowered intake plane at ~8'-6" AFF (LDD-07 capture field)
- Updraft air curtain at counter front
- Inline blower at east exterior wall
- Material seams only at zone boundaries — never through center
Open items / engineer review
- Top material: solid surface · stone · stainless at BBQ?
- Korean BBQ surface: flush removable plate vs built-in pop-up
- Counter overhang for seating (15–18" comfortable)
- 36" counter = standard counter-height stools
- Storage below + dishwasher integration
- Power at counter + USB-C at seating side
- Prep sink at counter or perimeter only
Cost drivers
Counter top (50 sqft × $100–250) $5–12.5K · Cabinetry $12–28K · Korean BBQ unit $4–10K + plates $0.5–1.5K · Bridge induction $3–8K · Counter electrical/plumbing $1.5–4K · Air curtain hardware $2–4K. Total: $25–55K (folded into $95K Kitchen line).
Air-gap concerns
- Counter performance depends on LDD-07 vent working. Solving the vent solves the counter.
- 42" depth = 17% higher top material cost. Worth it for social use.
- 14' run without center seam needs jumbo slab, solid surface, or seamless stainless. Pick now.
- Counter overhang structural support — 15–18" overhang on 42" creates a moment; engineered substrate.
- Outlet placement may conflict with air curtain front edge.
- Korean BBQ heat tolerance — counter material at BBQ plate sees 200°F+ cyclic. Engineered stone can crack; soapstone/stainless tolerate.
