Build playground in vacated establishment (5)
I believe the answer is:
erect
'build' is the definition.
(erecting is a kind of building)
'playground in vacated establishment' is the wordplay.
'playground' becomes 'rec' (short for recreation ground).
'in' means one lot of letters goes inside another.
'vacated' says to hollow out the word (remove centre letters).
'establishment' with its centre removed is 'et'.
'rec' going within 'et' is 'ERECT'.
(Other definitions for erect that I've seen before include "Upright; construct" , "Rigidly upright" , "Build, upright" , "Upright or vertical" , "Crete (anag)" .)
