London's is mostly midrise, no skyscrapers. They merge in styles from florid earlier examples that have hints of the arts and crafts period (such as the entrance addition to Selfridges), to the craze around Egyptology and ziggurat towers after the great archaeological finds of the 1920s (such as the Carreras Cigarette Factory), to the pared down Scandic style (read: proto fascist leanings, such as Senate House) and finally the streamlined machine age of automobiles and ocean liners, coming to moderne, ultimately one step away from modernism itself (such as the Isokon flats).
Senate House would be the tallest
but Battersea Power Station the largest - long the largest brick building (formerly it would have been the old Wembley Stadium, demolished in the '00s).
