The cream ones are the same ones our house is built from. The lower red ones on right of picture are basic engineering bricks and then the darker red ones are the same as ones used to build house behind us.
Basically the brickies cocked up and thought they were to use the same brick as the house for each section of retaining wall they had. My neighbour on left has a red rough faced brick for the house so they used the same for their bit of retaining wall.
Think it cost the developer a fortune because they were supposed to use the cheapest brick going.
