On Waterloo Street, there are five neighbours: the Chaes, the D'Costas, the Lams, the Mazumdars and the O'Neils. All neighbours live either adjacent to, or directly across the street from one another. Two of their houses are white, one is grey, one is green and one is blue.

From the clues below, determine which side of the street each neighbour lives (north or south) and the colour of their house.

1. The two white houses are directly across from one another on the west end of the street.

2. The Chaes do not live adjacent to either of the white houses.

3. The D'Costas live on the same side of the street that the Chaes live.

4. The blue house is immediately east of the D'Costa house, on the same side of the street.

5. The Lams house is not grey or white, and is next door to the O'Neils (which is on the south side of the street).

6. The Mazumdar house is directly across the street from the Lams.
