City wall with banana on? (9)
I haven't cracked this one yet — but Fifteensquared have:
DAM (wall) after ROTTER (banana) Maybe – Are bananas particularly known for rotting? (at least they signal it by going black first) All fruit rots. Some quicker than bananas. Edit: I’ve been put right: Bananas rot faster than other fruit and give off ethylene (C₂H₄) that helps ripen and rot both themselves and other nearby fruit

Keep say eight thousand building blocks in the OXO Tower? (10)
I haven't cracked this one yet — but Fifteensquared have:
STOCK (keep) CUBES (Building blocks) OXO is a brand name for Stock Cubes, but I cannot explain away “eight thousand” (20 cubed?) in the clue. The OXO Tower is now an art gallery on the South Bank of the Thames between National Theatre and Blackfriars Bridge. From Comment #2: Eight (8 = 2^3) and thousand (1000 = 10^3) are both examples of cubes (thus the final “?”) I might have not read 8000 and treated them separately if the clue had been worded “a thousand and eight”
