Surface from Notts town moving one end of street to the other (7)
I believe the answer is:
worktop
'surface' is the definition.
(I have seen 'Practical surface' mean 'worktop' so perhaps 'surface' could also mean 'worktop')
I cannot understand how the remainder of the clue works.
(Other definitions for worktop that I've seen before include "Surface on which to toil" , "Kitchen unit surface" , "Surface in kitchen for preparation, etc" , "E.g. kitchen surface" , "Practical surface" .)
