hi, I think is better for you to construct kitchen base. have feedback that it will help to last longer for cabinet. as for false ceiling, u can do without them to cut costs. experience and feedback from many of my friends and from some IDs, renovation package is just their marketing strategic. The add on from the package usually is much more expensive to cover back their earning. if you need more quote, can pm me for my ID contact. I engage him after meeting a fews other id. price wise is reasonable and service and workmanship is good.
