Tell the kitchen workers where you want to place the hob. they will measure how big the hole needed. for hood, just ask the installer to install. they know what height needed. simple as that. you just need to know where you want to cook. that place should be lengthy enough for the hood and hob.

What you pay is what you get... they don't have much color choice...

That's my perception too until i visit their showroom... price very much lower than SC... for a reason... cheap... lesser choice of design n color.
