What are these bricks?

I am in the process of buying a house and the front brickwork is puzzling me.

There is a row of concrete bricks in between the red bricks at the front /bottom of the house, and I just don't know what they are. Can anyone shed any light?

I don't know if it has been underpinned (it is high up), or it's perhaps some sort of flooring? My friend said it might be for decoration - but I can't see that somehow? It is a 60's build.

Thanks in advance!

looks lika a stringer course,purely decorative.
