Design checks

Geometry ✓

Nothing to report.

Layout and comfort 1

  • WC (ground floor) has no window and needs mechanical exhaust. Why

    Without a window this wet room needs a mechanical exhaust fan to the outside.

Feng shui ✓

Nothing to report.

Preferences from common Vietnamese feng shui practice — explained, optional, never a requirement.

Geometry, circulation, daylight and hygiene checks for concept design — not a building-code, structural or planning check.
