The station acted as the Espoo station building from 1903 to 1981, and the post office was also moved to the station as soon as it was finished, when the offices of the stationmaster and post officer were combined.
Rakennuksessa toimi Espoon asema vuosina 1903–1981 ja myös posti siirtyi asemalle heti sen valmistuttua, kun asemapäällikön ja postiaseman hoitajan virat yhdistettiin.
