Private Office is a separate use type from [[bim-professional-office-key-plans|Professional Office]]. Each Private Office suite opens directly onto the shared building corridor — there is no internal bilateral corridor within the Private Office floor area. The tenant is typically an individual professional rather than a firm. Suite geometry is computed using the [[bim-building-width-method|Building Width Calculator]] and the per-use-type values catalogued in [[bim-zone-depths-per-use-type|zone depths per use type]]; the Key Plans feed the [[bim-tile-system|Tile system]] and the [[bim-floor-plate-methodology|floor plate methodology]].

## The three sizes

| Size | Code | Area (m²) | Area (SF) | Façade frontage |
|---|---|---:|---:|---|
| Small | PO-1 | 30 | 325 | 13'-5" (4.09 m) |
| Medium | PO-2 | 43 | 465 | 19'-3" (5.87 m) |
| Large | PO-3 | 64 | 685 | 28'-6" (8.69 m) |

Total when stacked side-by-side: 137 m² / 1,475 SF.

## Zone vocabulary

| Zone | Depth | Note |
|---|---|---|
| Zone 1 — Habitat | 5.9944 m (19'-8") | Flagged for review at final [[bim-key-plans-index|Key Plan]] sign-off — marginally under the 6.0 m European Lighting Standard |
| Zone 2 — Magazine | 1.3716 m (4'-6") | Shallow storage; minimal shared storage compared with multi-person suites |
| Zone 3 — Corridor | 0 m | None — each office opens to the shared building corridor |

## PO-1 (Small) — the canonical sample

PO-1 is the methodology demonstration that anchors the entire Key Plans system. The derivation begins with furniture arranged around a central point, then adjusted to satisfy the German Circulation Law and the European Lighting Standard.

**Furniture:** one desk and chair (Steelcase), one 3-person round table, one filing cabinet, one credenza, one bookshelf, one coat rack.

**Dimensions:** façade frontage 13'-5"; Habitat depth 19'-8"; Magazine depth 4'-6"; total depth excluding corridor 24'-2". Two mullions span the façade; door swings inward from the corridor side.

**Occupancy:** 1 workstation per 30 m² (325 SF); assembly occupancy load 6 persons per 5 m² (54 SF per person) — used for IBC egress calculations, not actual daily occupancy.

## PO-2 (Medium)

PO-2 adds a second desk and chair and a second credenza to PO-1. The single 3-person round table, filing cabinet, bookshelf, and coat rack remain at quantity one.

**Dimensions:** façade frontage 19'-3" (split 10'-0" + 9'-3"); Habitat and Magazine depths unchanged at 19'-8" and 4'-6".

**Occupancy:** 2 workstations per 43 m²; 22 m² (233 SF) per workstation.

PO-2 is approximately 100 SF larger than PO-1, not double. The shared furniture does not duplicate — this non-modularity is foundational to the Key Plans system. Per-person rentable area is not the design driver; quality of the space is.

## PO-3 (Large)

PO-3 adds two filing cabinets, two bookshelves, and two coat racks relative to PO-2, reflecting a third occupant.

**Dimensions:** façade frontage 28'-6" (split 10'-0" + 9'-3" + 9'-3"); Habitat and Magazine depths unchanged.

**Occupancy:** 3 workstations per 64 m²; 21 m² (228 SF) per workstation.

PO-3 represents three professionals sharing a suite that retains the single 3-person round table — typically a partnership or a small practice with two professionals plus an administrator.

## Furniture distribution across a Private Office Tile

| Size | Share of tile |
|---|---:|
| Small (PO-1) | 80% |
| Medium (PO-2) | 10% |
| Large (PO-3) | 10% |

Most Private Office Tiles are predominantly PO-1 cells. Tenants who require PO-2 or PO-3 space lease it explicitly; the building optimises for PO-1 throughput.

## Licensing vs leasing

Private Office tenants are likely to operate under a licensing agreement rather than a traditional lease. The rent is fixed pricing across the three sizes. Building IDs are issued per workstation: one for PO-1, two for PO-2, three for PO-3. Common Area Costs are not broken out separately for Private Office tenants.
