I have custom made some cabinets and wardrobes and most of the doors cannot close properly. The reason given is that solid wood is always "curved". I did not have such problem with the cabinets and wardrobes in my old house. Is what the carpenter said true or is he just supplying inferior solid wood?

Hi, I just got the key to my 4-rm resale flat. Would like to seek advice from the gurus here if there is anything I should look out for in the renovation in terms of FS. Floor plan attached. Thanks.
