You have a blockage in your drain line just past where the kitchen sink drain ties in. You should call a plumber to run a snake through your drain. DO NOT pour acid down your drains! This will ultimately make things a whole lot worse in the future.
She lived and worked in a smaller apartment on the second floor
In Springfield, MA, it is a house consisting of 2 apartments, one on top of the other. The first floor apartment is a standard tenement layout - living room, dining room, kitchen (front to back) plus a bedroom-bathroom-bedroom on the side (typically on the right). The first floor also has a staircase up to the second floor for another two bedrooms and a bath on top of the lower level BR-BA-BR layout. The 2nd floor apartment has only the living room, dining room, and kitchen on the 2nd floor. A set of stairs up to the 3rd floor for 4 bedrooms and a bath. This way, each apartment has 4 bedrooms without a large lot size.
The architectural name for it is a "western false front" design.
Of course. How else would they get to the second floor of their homes or the fourth or fifth floor of an apartment building? They did not have domestic elevators.
Generally, it does include a kitchen area and a bathroom. However, the kitchen area is usually fairly open to the rest of the floor plan, but the bathroom is a separate room.
Yes, always. If the apartment looks like it only has one floor then there must be a hidden staircase somewhere that you haven't found. Sometimes the people who built the apartment & own them don't want the renters to know about all the extra space. It's kind of a inside joke.
A builder floor apartment is one wherein the builder buys a piece of land, constructs flats in the form of a building, and sells out one or more of them. Principally there is no difference between a builder floor apartment and residential apartment, in case one is opting to buy a flat or apartment.
That riddle is old. The man is a dwarf. He can't reach the 20th floor button by himself.
That part of the kitchen upon which you walk
An apartment on more than one floor is a multistory apartment.
Ernie and Bert live in an apartment in the basement, Gordon, Susan, and their son, Myles live on the first floor, and Maria, Luis, and Gabi live on the second/top floor.
In America, a flat is an apartment. You might call that person an apartment dweller, a tenant, a renter, or in the case of a coop, they would be called the owner.
