The reasons why the terrace is 30cm higher than indoors are as follows:
1. To ensure that the room below is not hot: the terrace has a thick insulation layer on the cast-in-place floor. This will ensure that the room under the terrace does not get too hot.
2. Suitable for growing flowers, planting grass and drying clothes: The terrace protrudes from the outer wall and has ample sunlight, making it more suitable for growing flowers, planting grass and drying clothes than indoors.
3. Social networking and gatherings: The terrace is also a suitable place for social gatherings and gatherings, and the smoke from barbecue will not pollute the interior.
In short, the design of the terrace that is 30 cm higher than the interior takes into account the balance between practicality and aesthetics, adding comfort and warmth to the living environment.
