It seems that the post you provided does not mention anything related to maintenance report feedback for a public flat house in Singapore. The term "greenwood sanctuary" and "admiralty singapore" do not seem to be related to any specific location or facility that would fall under the category of public housing maintenance reports. Therefore, the answer is "False" for the relatedness question.
