..was thinking further and came up with this design that won't clash with fengshui..

:
..again, light blue ish hood+hob, this length quite long so both sides can have space for food preparation...
..orange part is the sink, which means that the water and drainage pipes will have to be laid all the way there, which should be ok, just that chiu have to pour in hot-water once in a while to flush it... it is placed more on the right-side so that after washing/cutting, food can be transferred over to the hob area easier ...
..red square is the fridge, forming the triangle for the standard cooking work flow...
..sliding/bifold door there to close it + half-height wall with half-height glass panel to see-through from kitchen to living area, or can go without both if chiu r going for the open-concept kitchen ... but with the sink there chiu might want to enclose it better...

..wait everywhere also wet wet...
..the hob and sink position can also switch, but if like that, then the cooking area will become smaller, also not good...(I estimated to be around 1800 length nia...)
..that gap there between the hob and sink ish really annoying ...

...why HDB sabo us and plan until so stupiak???
