  4. Outlet accessibility

[Window]

## Standard Apartment Floor Plan Tips

### Standard Unit (84 sq m / 900 sq ft) Layout Tips

```
Living room: approx. 5.5 x 3.5m
  -> 3-seat sofa (220cm) + coffee table + TV stand + side table
  -> For L-shaped sofa, verify clearance (minimum 300cm wall space)

Kitchen: approx. 3 x 3m
  -> L-shape or I-shape + island table (if space permits)
  -> Fridge location: near entrance (minimize traffic)

Master bedroom: approx. 3.5 x 3.5m
  -> Queen bed (160cm) + nightstands on both sides
  -> Dresser or vanity near window

Second bedroom: approx. 3 x 2.5m
  -> Single bed + desk (or loft bed + desk)
```

Ambient (overall): Ceiling fixtures, recessed lights — overall room brightness
Task (work): Desk lamp, pendant — focused work area lighting
Accent (mood): Floor lamp, candles — atmosphere creation

Height standards:
  Pendant (over dining table): 75-90cm above table surface
  Floor lamp: Beside sofa, reading height 120-150cm
  Wall sconce: 150-170cm from floor
```
