The official 12 Girmmauld Place LEGO® set has a built in interactive feature. When the back of the building is pushed towards the front, the two front buildings slide open to reveal a third.

This motion will be connected to a motor so the interaction can be automated.
This interaction will have an interesting effect on the GPS and mapping tools. Unlike most buildings, this building only exists at certain times. OR the building could be in hiding until the mapping system receives a request for this address.
This interaction will only require a large EV3 motor and the EV3 hub:
In this example, the location is only available when recently requested:
REPEAT-EVERY 30 Seconds
IF LastGpsRequest < 30 Minutes THEN
LocationStatus = TRUE
RotateMotor to 0
ELSE
LocationStatus = FALSE
RotateMotor to 360
ENDIF
ENDREPEAT
In this example, the building is only available between 11:00 am and 1:00 pm. A GPS request will return false when the building is not available:
REPEAT-EVERY 1 Hour
IF Hour > 11:00 AM AND Hour < 1:00 PM THEN
LocationStatus = TRUE
RotateMotor to 0
ELSE
LocationStatus = FALSE
RotateMotor to 360
ENDIF
ENDREPEAT
ON RequestGpsLocation EVENT
IF LocationStatus == TRUE THEN
RETURN GpsLocation
ELSE
RETURN FALSE
ENDIF
ENDEVENT
