If you are renting a place before the house, i suggest that you do some homework first. My uncle's house at Jalan Melor suppose to start construction like end 2017 but dragged till Oct 2019 then start work. Initially was an A&A then follow by Reconstruction but his builder found out that there is no column in the house hence delay... end up became a New Erection. Heard him saying that initially don't need piling for A&A but ended up with piling for Reconstruction cause adding 1 more attic. Lucky his builder is quite fast with structure works, they complete the works in Dec and now starting architecture work.
