1. Convenient ventilation: the shadowless wall can let the wind and sunshine in the yard pass unimpeded, make the yard cooler in summer and more breathable in wet season, which is more conducive to the overall environment of the yard.
2. Cost saving: The screen wall needs to spend a certain amount of money and energy to build. If it is not covered, this part of the cost can be saved and can be used for other purposes in the small courtyard.
3. Increase outdoor lighting: Without screen walls, the sunlight can directly reach the small courtyard, increase outdoor lighting, and make the whole small courtyard brighter.
4. Feng Shui: In rural areas, many families think that screen walls can block evil spirits and suffocate. If you don't build a screen wall, it may affect your family's feng shui fortune.
Therefore, whether it is necessary to build a screen wall depends on the actual situation and personal needs. If you pay attention to feng shui and beauty, you can choose to build a shadow wall; If you pay more attention to practicality and economy, or the yard area is small, you can not build a screen wall.
