<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">housing area</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for estate that I've seen before include "Property with considerable land" , "Rank - housing development - what's left in a will" , "All money and property owned at time of death" , "Scheme of new houses" , "Group of suburban houses or industrial units" .)
