Scientific research shows that houses with * * * walls are easily affected by the noise of neighbors' lives, which may lead to the decline of sleep quality and quality of life. In addition, the * * * wall structure also increases the risk of fire spread. According to the principle of architectural engineering, independent wall structure is more conducive to sound insulation and fire prevention. Houses adjacent to bedrooms usually have privacy problems, which may affect the occupants' private space. Therefore, from a scientific point of view, choosing a house that is not connected with the neighbor's bedroom is more conducive to the quality of life and safety of the occupants.
