Oy Julius Tallberg Ab leases business premises at Aleksanterinkatu 21 Historical aspects of construction Aleksanterinkadun länsipää sai hahmonsa 1830-luvulla, kun Kluuvia ryhdyttiin kuivaamaan ja Ehrenströmin luomaa asemakaavaa laajennettiin. Intendentti Carl Ludvig Engel laati suunnitelmat uudeksi katu- ja korttelijaoksi vuosina 1837-38. Kortteli 96 muotoutui varsin suureksi verrattuna kaupungin perinteiseen suorakulmaiseen korttelirakenteeseen. Tämä johtui siitä, että diagonaalisesti keskustan katuverkostoon Lue Lisää Elia Heikel ja uusi rakennustekniikka Elia Heikelin tärkeän panoksen avulla toteutettiin rakenteellisesti haastava näyteikkunakerros sekä kerrosten väliseinättömät myymälätilat. Heikel käytti täällä johdonmukaisesti rautarakenteita. Näyteikkunoiden kohdalla hän vahvisti rakenteita kaksinkertaisilla rautapilareilla. Ylempien kerrosten julkisivuja on vahvistettu piirustusten selosteen mukaan rautarakenteilla ja teräsbetonilla.
