I want to know the answer to the following question:
What was designed for the west front of the abbey but not built?
All the background I'm provided with is that "Images of the abbey prior to the construction of the towers are scarce, though the abbey's official website states that the building was without towers following Yevele's renovation, with just the lower segments beneath the roof level of the Nave completed.". Is that enough to answer the question?
Answer: no
