@HoppaHouse, I would get them to level the floor. From your previous posts I think it would annoy you if you didn't ask them to. It would niggle at me.
I've not set design at the moment but I know I'm not having wall units along the cooker side. Pan drawers and shelves, which apparently really confuse kitchen people as they seem to want to know what I'll put on it. New Dad Builder just keeps saying I'm going to put a cactus on it LOL! On the other side I'm having an L shape with a peninsula breakfast bar. The sink on the peninsular. Currently debating about a level bbar or a raised one. Hmmm. The storage on that side is (currently!) a 600 tall unit, a 1000 tall corner with Le Mans pull outs, a 500 drawer pack, a 950 L corner base with snazzy double doors for access and 2 wall units.
I am not convinced I will have enough storage but I don't want to fill the wall on the cooker side with wall cabinets. The stupid thing is I know it's not a small kitchen. I am just a hoarder!!
As an aside, from previous experience of putting in a new kitchen, check the depths of the cupboards you are planning to use for your dinner plates. In our previous kitchen we didn't and they didn't fit!! Our new all units are 330 deep but I think the standard is 300. For some reason plates are bigger than they used to be!
@Avocuddl, have you thought about putting your sink at the end of the island where there are 3 dots (?) in the photo? That way you could have a kind of semi-circle for seating.
@WorrisomeHeart, you can use a top box for above the sink. I think a normal one would bet in the way.
@MyNameIsJane, I wish I could have 3 60 tall units! That would be soo good! Just like in the mags. Are they pull outs?
