[3] Iversen's early works are sometimes described as Art Deco, but after World War II, his buildings became increasingly modern, and he became one of Southeast Asia's most important modernists.

He exhibited an artistic streak from a young age, and graduated from the Royal Academy in Copenhagen in architecture.

His oeuvre includes numerous government buildings, hospitals, schools, cinemas, radio stations, and churches.

In 1950, Iversen won in a design competition for a post office saving bank in Malaya while he was recovering from a kidney operation;[1] the prize was $5000.

The delightful visual quality of the facade treatment was later compromised when the occupants painted the clear glass panels to reduce the sun glare and resultant heat gain.

It originally housed a bazaar at street level, and a hotel and the Celestial Cabaret occupied the upper floors.

It was a favourite watering hole for European expatriates up until World War II when it became a favorite spot for Japanese officers.

In the 1970s, Lam Look Ing Bazaar housed the Perak Emporium, an early incarnation of the air-conditioned department store.

[21] This cornerstone for the building in Ipoh was laid by YM Raja Idris Shah ibin Almarhum Sultan Iskandar Shah, the Raja Muda of Perak in July, 1955 Iversen was hired to remodel and enlarge his project, and the building's library includes a mosaic floor of the Malayan Peninsula.

Located across the Cockman Street, Ipoh (currently Jalan Dato Onn Jaafar) from the Cathay Theatre.

[26] The firm Iversen established lives on under the name Pakatan Akitek Sdn Bhd, in Kuala Lumpur, and there are literally hundreds of buildings in the Malayan peninsular from either B.M.

The international style became a force in Southeast Asia in no small part due to Iversen's efforts.
