When scouting for a dream home, it is a good idea to observe its surrounding area, its neighbourhood. Though this doesn't literally mean the people who live next door to you, but rather, what is next door or in close proximity to your property. Similar to suffering the pain of having noisy real-life neighbours, having a negative 'neighbour' can negatively impact your property.
Here is what you need to look out for:
Burial areas are Yin areas and it is not good to have an overly Yin place near or next to your home. Though most graveyards are clean and beautiful these days, they do not necessarily embody negative Qi. Therefore, living near or next to a graveyard likely has a psychological rather than a Feng Shui effect. However, if there's a busy road between the property and the graveyard, any Yin Qi from the graveyard will be dispersed.
Schools are considered Yang Qi because it is usually always busy and noisy. Living next to one is usually not detrimental or negative in Feng Shui but common sense will tell you that it may cause sleep disruption, which may not be good for the health of the occupants.
Temples are spiritual grounds and are considered Fire Qi. Employ the appropriate use of the Water element and/or Qi mouth (Main Door or Main Gate) to easily resolve the Fire Qi issue. But if the Fire Qi is good for the property, then having the temple there may even be beneficial.
Petrol/gas stations are considered to be of Fire element. Much like temples, you need to check if the Fire element is beneficial to your property according to Xuan Kong or other Feng Shui calculations. In general, basic Feng Shui dictates that living too close to an overly strong Fire element denotes loneliness and lack of progress. The solution? Employ appropriate positioning of Water within the property's compound.
Similarly to petrol/gas stations, the same also applies to power substations. If all is good, then there's nothing wrong with living next to one. In Feng Shui, the concern is more on electric pylons than substations. Of course, electromagnetic fields from the substations may well be a cause for health concerns but substations themselves have no substantial Feng Shui impact.
Likewise with highways, LRT/monorail lines are also of piercing merciless Qi. The main thing to consider is which sector it pierces and whether or not the station casts a shadow on your property, thereby blocking the Qi from entering. But to be on the safe side, better to avoid a property close to the LRT line or station.
When a pedestrian bridge is very close to your property, it is a negative feature because the piercing Qi will hit the property. So it is best to avoid it. But no worries if it is far away.
