Delay putting wire sculpture in part of building (9)
I believe the answer is:
stairwell
'part of building' is the definition.
(I know that stairwell is part of building)
'delay putting wire sculpture in' is the wordplay.
'delay putting' becomes 'stall' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'sculpture' indicates an anagram.
'in' means one lot of letters goes inside another.
'wire' is an anagram of 'irwe'.
'stall' placed around 'irwe' is 'STAIRWELL'.
Can you help me to learn more?
(Other definitions for stairwell that I've seen before include "Shaft in building housing steps" , "Space flight" , "where flight goes" , "Shaft for walking between floors" , "Shaft for flight" .)
