Is that corner lower lying than the rest, Gareth, and you want to raise it to the same level, or have I misunderstood?
If that's the case, you'll still need to aerate like the rest of the plot, and then you could add topsoil to level up the area, followed by a bit of reseeding. If it's shady, use a specific mix for that, as already suggested. It does help quite a bit.
It does look like it's been cut recently - very short, but that may just be the pic. Unfortunately, as has been said, new builds are notorious for the poor ground where lawns are laid. Avoid scalping the grass when you mow - cut more often and leave it slightly longer. The general rule is take no more than a third of the length off. That helps the grass thrive too
