Panic relating to wings at front of mansion (5)
I believe the answer is:
alarm
'panic' is the definition.
(thesaurus)
'relating to wings at front of mansion' is the wordplay.
'relating to wings' becomes 'alar' (I've seen this before).
'at' says to put letters next to each other.
'front of' suggests taking the first letters.
The first letter of 'mansion' is 'm'.
'alar'+'m'='ALARM'
(Other definitions for alarm that I've seen before include "Unnerve" , "Announcement of danger" , "Tocsin" , "Scare or worry" , "Safety bell or alert signal" .)
