The direction of the house is not only based on preferences but also depends on the area, terrain, wind direction and location of surrounding roads. In which, South-facing houses are often highly appreciated because they have many advantages in lighting and ventilation.
Houses facing South receive a lot of natural sunlight. In winter, sunlight can shine deep inside, making the space brighter and warmer. In summer, although the sun shines directly, the sunlight is not too harsh on the interior. In addition, this direction also helps the house ventilate well, keeping the air always dry and fresh.
In general, houses facing South, Southeast or Southwest often receive a lot of sunlight. Just each room having about 2-3 hours of sunshine a day is enough. Even 1-2 hours of sunshine also helps reduce moisture, limit bacteria, regulate temperature and increase air circulation in the house.
However, when designing a house, many other factors need to be considered. For example, the direction of the surrounding roads may not coincide with the standard East-West direction, thereby affecting the overall layout of the house.
In addition, the climate characteristics of each region are also factors to consider. In areas with prolonged heat, limiting the surface of walls and windows facing the West will help reduce heat absorption in the afternoon. Conversely, in places with cold winters, maximizing natural sunlight will contribute to keeping the space warm and saving energy.
In actual design, homeowners cannot always choose the ideal house direction. Therefore, the solution lies in the arrangement of functions inside. Main living spaces such as the living room and bedroom should be prioritized in locations with the best lighting and ventilation. Sub-areas such as stairs, warehouses, and toilets can be arranged in less favorable directions to reduce the impact of hot sun or cold wind.
