Disruption to the City Square during work for the $11 billion Melbourne Metro Rail has rattled the windows of a nearby luxurious penthouse and one celebrity resident has already been transported to "hell" over access to her private car park.

Pettifleur Berenger​, star of the The Real Housewives of Melbourne, lives in a multi-million-dollar penthouse with sweeping views of the city, and is angry about the City Square being turned into a construction site.

"It's going to be hell," Ms Berenger said about the noise, dirt and interruption from the eight-year construction that begins in 2018 but will affect locals from 2017.

"It's going to be a nightmare."
