That kitchen is stunning! That's exactly how we want our wall units to be, I love the clean lines. We wanted a scabdi look but I think it's out of budget - where did you get the bottom unit fronts from?
This is our plan - by default, using 2120 tall units and standard 720mm wall units our gap would only be 490mm which is probably not enough (though I've found a hood that allows 500mm).
I think our options are as follows
1) Go up a size to 2300mm tall units and keep the 720 wall units - this would give a gap of 670
2) Stick with 2120mm tall units and use 575mm wall units - this would give a gap of 635mm (downside is we couldn't have bifold wall units)
3) Stick with the original plan but get a hob that includes in-built indiction (the width of unit kind of ruins the symmetry)
Unless anyone else has any clever ideas?
