I looked out at the front of my apartment house.

Then I heard the front door of the apartment house close.

We went around to the front of the apartment house and I got out.

Go to an apartment house and get someone to let you in.

I'll walk up behind you and time things so we go in the apartment house together.

The apartment house was probably built between 1923 and 1925.

However, No. 1 was taken by the 29-story apartment house to the north.

It happened four or five times between my apartment house and here.

It made its way through the apartment house, though, because my wife called the office.

But never outside the apartment house in which we lived.
