"Brompton" in trendy Paddington, part of the city's eastern suburbs, was created by joining two terraces built dating from 1877 to achieve a rare 16 metre-wide, double-fronted home.
Sitting on a 404 sqm block of land, the property was inspired by high-end European architecture, typically found in North London or New York's SoHo.
A five-year renovation project has given the property plenty of wow factor across its five-bedrooms, five-bathrooms and four-levels.
Fittings have been sourced from across the globe and include oak floors and French wallpaper.
The property also has as a cocktail room, renovated sandstone cellar, roof terrace and courtyard as well as a heated spa/pool.
The new owners will find "Brompton" only a short walk from the trendy coffee and cocktail strip of Five Ways in Paddington.
While there is front forecourt parking, the property is also handily placed for a short commute by train or bus to the Sydney central business district.
The median price for a three-bedroom home in Paddington is $3.125 million, according to Domain.
