Ancient geomantic omen is different from modern geomantic omen. Most of the ancient buildings are simple, and the ability to change outside the area is very weak, so it is best to have no hidden dangers around the house, especially behind the invisible house. The performance of modern architecture is stronger, but the overall environment is more crowded and people's psychological pressure is getting bigger and bigger, so the house mainly pays attention to these points: 1. Ventilation and lighting conditions of the house; 2. Is it quiet enough? 3. There are no pollution sources around (such as sewage rivers, garbage dumps and factories near the community). Others, such as shopping, transportation and education, are secondary.
According to your situation, as long as the distance between the two buildings is wide enough and you are on the fourth floor, its natural conditions will not affect you at all. The only worry is whether there are many beautiful and handsome men going swimming in the community, and spending a lot of time enjoying it may affect your normal life order. I suggest you exercise the ability of color blank, so that you can be foolproof.
You don't have to pay any attention to the key superstitious elements of Feng Shui. Happy wherever you live, this is good feng shui!
