Hi there, I just joined this site & find it really resourceful. I understand from your courses that a canal in front of the maindoor of an office is good. But what if there's a HDB flat in between? The flat is about 20 metres away from the office. & how far is the distance, must the canal be from my office building before it's consider meaningful? The office is about about 300 metres away. Separated by flats & roads. Is it also alright to a road & a carpark behind the office? Thanks, gt
