Ties up place (4)
I believe the answer is:
site
'place' is the definition.
(site is a kind of place)
'ties up' is the wordplay.
'up' indicates anagramming the letters (letters get chucked up).
'ties' with letters rearranged gives 'SITE'.
(Other definitions for site that I've seen before include "internet location" , "Situation (of a building)" , "Area set aside for building" , "Locate - place" , "station" .)
