The Key Plan Directory inventories every distinct floor-plate sub-area that the Building Information Model (BIM) recognises. Each entry pairs a Development Class with a Typology and (where relevant) an Eco Region, yielding a file-name slug that is referenced from every downstream BIM artefact — Design Token Community Group (DTCG) tokens, Industry Foundation Classes (IFC) entity classifications, Rust solvers, slide decks, and regulation overlays. The Directory underpins the [[bim-tile-system|Tile system]] and the [[bim-floor-plate-methodology|floor plate methodology]]; per-use-type interior geometry is set by the [[bim-building-width-method|Building Width Calculator]] and the [[bim-zone-depths-per-use-type|zone depths per use type]].

The current Directory (V2, dated both 2025-01-07 and re-dated 2026-01-06 — identical content) contains **72 key plans across nine Development Classes**.

## V3 Master Summary reconciliation

The V3 Master Summary table (January 2026) supersedes earlier iterations for the General-class leasable typologies. Authoritative numbers:

| Use type | Z1 Habitat | Z2 Magazine | Z3 Corridor | KP-S (m² / SF) | KP-M | KP-L |
|---|---:|---:|---:|---|---|---|
| Private Office | 6.0 m / 19'8" | 1.4 m / 4'6" | — | 30 / 325 | 43 / 465 | 64 / 685 |
| Laboratory | 6.8 m / 22'3" | 4.8 m / 15'9" | 3.0 m / 10' | 195 / 2,099 | 316 / 3,401 | 401 / 4,313 |
| Academic | 4.7 m / 15'5" | 3.0 m / 3'7" | — | **105 / 1,131** | 240 / 2,583 | 378 / 4,070 |
| Business | 6.0 m / 19'8" | 7.3 m / 23'11" | 2.7 m | 311 / 3,350 | 400 / 4,302 | 669 / 7,524 |
| Medical | 7.2 m / 23'10" | 4.9 m / 16" | 2.9 m / 9'5" | 223 / 2,402 | 331 / 3,568 | 486 / 5,231 |
| Civic | 6.0 m / 19'8" | 7.2 m / 23'8" | 3.6 m / 12' | 270 / 2,912 | 577 / 6,215 | 822 / 8,850 |
| Professional Office (Initial Design baseline) | 6.0 m / 19'8" | 3.8 m / 12'5" | 2.0 m / 6'6" | 130 / 1,400 | — | — |

### Academic Small — reconciliation

The Academic Small key plan area appears at three different values:

- **87.7 m² / 944 SF** — Samples V2 "smaller" option
- **110.5 m² / 1,189 SF** — V2 Summary (February 2025)
- **105 m² / 1,131 SF** — V3 Master Summary (January 2026) — **authoritative**

The DTCG token in `building-width-calculator.dtcg.json` correctly carries 105 m² / 1,131 SF. The token in `professional-office-subtypes.dtcg.json` must be updated to match V3.

## Naming convention

Key plans use the convention:

```
key plan-{development-class}-{typology}-{id}[-{eco-region}]
```

Examples:
- `key plan-general-private office-small`
- `key plan-general-business-medium`
- `key plan-landscaping-bioswales-LL-1-boreal plains` (Eco Region suffix)

The Directory mixes two naming registers — short IDs (B-2, M-3, PP-1) and size labels (small / medium / large). Downstream code should accept both; the canonical slug uses size labels.

## FFE tile codes vs key plan footprints

Each Professional Office sub-type also carries FFE (Furniture, Fixtures and Equipment) tile codes representing 1/4-floor sub-allocations:

- `-1` = 1,100 SF
- `-2` = 1,400 SF
- `-3` = 800 SF

These are **not** the key plan footprints. A Medical M2 FFE tile code (1,400 SF) is distinct from the Medical Medium key plan (3,568 SF), which is the completed-sample full-suite area.

## Open questions

1. **Corporate Office key plan areas (Index 4–8)** are still TBD in every source document examined. When will Corporate Office samples land?
2. **Chiropractor and General Practitioner Medical specialisations** (Index 9, 11) appear in the Directory but have no completed samples. Are these intended as layout variants of the M1/M2/M3 footprints, or separate sample exercises?
3. **Eco Region variants for Bioswales and Parking** (Index 59–68) need climate-zone-aware key plan content — currently the Directory rows exist but no per-region sample sketches have surfaced.
