[1] Her father, Tigran Ter-Avetikian and his brother, Yervand, created the Philharmonic Hall of Yerevan, the City Council building on Shahumyan Square, and other noted works.

In 1926, simultaneously with her studies, she started working for Nikoghayos Buniatian [hy] and Alexander Tamanian, noted architects who designed the master plan of the city of Yerevan and many of its buildings.

[2] Ter-Avetikian graduated in 1930 and shortly thereafter, married fellow architect, Konstantin Hovhannisian [ky], who had attended YSU and was also employed with Buniatian and Tamanian.

She gained a reputation for corner structures and her ability to design in harmony with the surrounding spaces, utilizing such elements as concave arcades to offset the straight lines of a street.

She was the subject of a featured article in the magazine Architecture, Construction (Архитектура, строительство) in 2012, in which she and her work were compared to the noted Brazilian centenarian and architect Oscar Niemeyer.
