Before that you need to consider the following .
(i) you must check the water pipe inlet level is it sufficient . This area should be a turfing area before tiling. The owner never make the same level maybe the water pipe is too high.
(ii) The rubbish Bin can be demolished. So far , I didn't see any electric meter at that area. Please make sure the hacking work do not disturbing your neighbor wall.
There is no picture show the top part of the gate post & rubbish bin area . Cannot comments .
