There's one house on West Park Road which is 325 a month.
The second house is in Tithe Road.
Houses are in streets, seeing the street somewhat three-dimensional. The houses are not really on the street but next to it.
Why it is "on West Park Road" - well, the only explanation I can come up with is - that's just the way it is said. Maybe because roads are usually in the country and the dimensions are bigger.
Thousands of people were out on the streets for the protest.
The people are actually on the street, where normally the cars would be driving.
A band was playing a little way down the street.
The event is in a house in the same street or on the street itself, but at a distance.
