Block overlooking other houses (5)
I believe the answer is:
ingot
'block' is the definition.
(I know that ingot is a type of block)
'overlooking other houses' is the wordplay.
'houses' indicates a hidden word (part of the clue houses the answer).
'INGOT' is hidden in the letters of 'overlooking other'.
(Other definitions for ingot that I've seen before include "A brick shaped lump of gold" , "Block (of steel, gold, etc)" , "Metallic bar" , "A lump of metal, perhaps gold" , "Cast metal obtained from a mould" .)
