Architect Jenny? (4)

I believe the answer is:

wren

I believe this is a double definition.

'architect' is the first definition.
(Christopher Wren, 17th-century architect)

'jenny?' is the second definition.
(jenny wren is another name for a wren)

(Other definitions for wren that I've seen before include "A songster" , "Troglodytes troglodytes" , "Architect of St Paul's Cathedral" , "Farthing's emblem" , "A small garden bird" .)

I've seen this clue in The Sun.
