I'm trying to adopt this Display buildings in 3D example, but I found out that in my city (Minsk, Belarus) some buildings look flat like this:

flat building

The coordinates of this particular building are 27.552516, 53.897726 (lon, lat).

I checked out the attributes os this building in OSM and didn't find any special:

OSM attributes

There is only a number of floors as data about height, but it's the same for the rest of buildings which appear volumetric.

I haven't changed the code yet so I don't leave it here coz it's in the Mapbox example above. Could someone tells me how to fix that problem?

It looks like for some reason the extrude property for this building is equal to false. Try changing the filter for the layer with the extrude of buildings:

'filter': ['==', 'extrude', 'true']

// =>

'filter': ['>', 'height', 0]
