How it's used

Refers specifically to the floor at street level, which is distinct from the first floor in many Western contexts. In Hong Kong residential buildings, this is often referred to as the G/F or 地下. Using the term implies a focus on the structural position of the floor rather than the numbering system used by property management.

Examples

He lives on the ground floor of the building, so it's very convenient to get in and out.
Can you check for me if there is anyone on the ground floor collecting mail?

Common phrases

ground floor of the building

Common mistake

Do not confuse this with 地下, which is the standard term for the ground floor in Hong Kong addresses and building signage. While 底層 is understood as the bottom layer, it is less common in everyday navigation than simply saying 地下.
