Main Duplex Staircase

A duplex home is a small type of multifamily building with two connected dwellings that have separate entrances on a single property. Each dwelling is considered a duplex apartment.An imperial staircase (sometimes erroneously known as a "double staircase") is the name given to a staircase with divided flights. Usually the first flight rises to a half-landing and then divides into two symmetrical flights both rising with an equal number of steps and turns to the next floor.
