Heighten current garden wall -

Hi, Looking to heighten our current garden wall. The wall is spilt in two, one is 10m long and the second is 7.5m long. Heighten to a total of 65cm high. There will be two areas where the current wall will need to be returned back to the house to enclose an area. Two returns back to the house are 2.5m in length. The wall will then be tiled (another job) so won’t need a perfect finish. Current wall is painted breeze blocks. Looking to understand an estimated cost, I’ve attached a few photos of the current wall. Any questions let me know
