Hi,
one thing we learned recently when planning our new kitchen:
If the gas hob has the gas connection at the rear, then it will fit directly over a set of drawers and you can have all the drawers functional.
If the connection is to the left or right (or even front, though I find this hard to grasp) then the top drawer has to be a dummy.
To my total lack of surprise none of the hobs I have looked at has the details of where the gas connection is included in the 'blurb'.
Ho hum
