Either want to save moneh or have bad dealings experience with Consultant/Interior Designer.

or.......maybe the reno contractor dulan due to frequent last minute change from him.

One of my frens who own a reno business (he specialize in industrial renovation), sometimes lamented private house renovation have alot challenges due to unnecessary changes in last minute (he took some private house renovation due to low season order). Industry renovation mostly straight forward due to signed black and white. Any changes by the industry owner straight away additional bill.
