I believe the answer is:
facade
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">front of a building</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for facade that I've seen before include "Outer surfaces or face as of a building" , "ballet" , "(False) outward appearance" , "front of shop?" , "Front of building or outer appearance" .)
