First of all, based on the house type analysis, both of them are standard house types, which is fine. If both are in the north-south direction, it would be good to have north-south transparency. Comparing the two apartment types, D-type is better because the dining table of F-type is facing the bathroom and is on the left side of the entrance door. As soon as you enter the house, you can When you look at the restaurant, it's not hygienic, so I strongly recommend the D apartment, which is the absolute standard apartment.
Mountains and water do not have much influence on Feng Shui, and there is not much room for choice in Buildings 2 and 3. The buildings are already on the southernmost side of the community. Moreover, having mountains and water can be interpreted as being surrounded by mountains and rivers. How nice that you can go hiking and swimming on weekdays. When choosing a high-rise floor, you usually choose the middle one, but since yours only has 2.4.8 floors, I suggest you choose 8 floors. If the apartment on Building 3# is D-type, I strongly recommend you to buy it.
If there is a square behind building #2, the view will be better, but the noise will be considered. The square is not for appreciation inside the house, but to improve the quality of life. As long as the square is in the community and not far from home, it doesn't matter which building it is.
* In my opinion, type D is an 82-square-meter unit? Exactly Building 3? Then buy it.
