I believe the answer is:
theatre
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">playhouse</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that playhouse can be written as theatre)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for theatre that I've seen before include "eg The Globe" , "Place where plays are produced" , "Major area of military activity" , "Venue for plays, films and surgery" , "where you may get knifed" .)
