A balcony is an open platform projecting from the wall of a building, usually above the ground floor. They are commonly found on multi-level houses or apartments.
Do not confuse with balcony=yes/no/covered, which is used to indicate the availability of a balcony at a hotel or other tourist accommodation.
How to map
- Main article: Simple 3D buildings
Within an outline of a building (tagged with building=*), Draw an area and tag it with building:part=balcony. The additional tags are:
| Key | Value | Comment |
|---|---|---|
building:min_level
|
number | The number of levels that do not have a balcony (usually 1 or higher).
|
building:levels
|
number | The number of levels that have a balcony (always greater than building:min_level=* if it is used).
|
building:material
|
material | The main material of the parapet, which 3D maps can use to determine whether to render the balcony with a fence or a wall. |
Limitations
There is currently no tag to describe balconies that occur with gaps or at an interval: for example, this building has balconies at different positions depending on whether it is an odd or even floor. level=* is a close match, although it was designed for indoor mapping.

Columns of balconies on a tower block: for example, levels 1–20 (2nd to 21st storeys) at Markland House in West London (13623742591362374259, 13623742601362374260, 13623742611362374261 and 13623742621362374262). |
Rendering
Many 3D maps, such as F4 Map, currently render ways with building:part=balcony as an extruded solid that spans all levels it applies to (example).
Ideally, a way with building:part=balcony should appear as a half-height wall with a floor, repeated for each level it applies to.
