Room in northern Surrey to wander (7)
I believe the answer is:
nursery
'room' is the definition.
(I know that nursery is a type of room)
'northern surrey to wander' is the wordplay.
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'to wander' is an anagram indicator.
'surrey' with letters rearranged gives 'ursery'.
'n'+'ursery'='NURSERY'
'in' acts as a link.
(Other definitions for nursery that I've seen before include "Where kids learn" , "School for young children" , "to which children go" , "Place where young plants are grown" , "Kindergarten" .)
