Erector (7)
I believe the answer is:
builder
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">erector</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I have seen 'Erector of houses ' mean 'builder' so perhaps 'erector' could also mean 'builder')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for builder that I've seen before include "Constructor" , "Bob, eg" , "Erector of houses" , "Bob the - - (TV)" , "One involved in construction" .)
