This is the design..

The problem I have is that the gap from the worktop to the bottom of the unit next to the boiler unit will be approx 720mm. This seems quite high even though I'm 6ft2.
I can't position the boiler unit any lower as I have sockets underneath the boiler unit.
Any ideas of what I could do.
I could probably take the boiler unit higher up to the ceiling but then the tops of the surrounding units will be lower and will not look aesthetically pleasing.
