Dawn insures building (7)

I believe the answer is:

sunrise

'dawn' is the definition.
(I know that dawn can be written as sunrise)

'insures building' is the wordplay.
'building' is an anagram indicator.
'insures' with letters rearranged gives 'SUNRISE'.

(Other definitions for sunrise that I've seen before include "daily event" , "Time of full daylight" , "everyday occurrence in the East" , "It gets the day off to a bright start" , "See 21" .)

I've seen this clue in The Independent.
