Core Viewpoint - The article discusses the differences between "middle units" and "corner units" in residential properties, providing insights based on personal experiences with both types of housing. It aims to offer valuable references for potential homebuyers navigating the real estate market [1][2]. Group 1: Advantages of Middle Units - Middle units often feature well-designed space layouts, typically with three bedrooms and two facing south, providing ideal lighting and ventilation for families [7]. - The total price of middle units is generally more affordable, making them accessible for first-time homebuyers [10]. - These units are in high demand among buyers with rigid housing needs, as they effectively alleviate the cramped feeling often associated with traditional two-bedroom apartments [12]. Group 2: Disadvantages of Middle Units - Middle units often come with shared public corridors and additional space that is difficult to utilize effectively, leading to wasted area [18]. - They typically lack south-north ventilation, which can affect air circulation and comfort, especially in hot weather [21]. - Noise disturbances from neighbors can be a significant issue, as walls are often shared with adjacent units, impacting privacy and tranquility [25]. - The proximity to public corridors can compromise privacy, particularly for bathrooms and bedrooms [26]. Group 3: Advantages of Corner Units - Corner units benefit from south-north ventilation, allowing for natural airflow and reducing reliance on air conditioning [27]. - They usually have a higher usable area ratio, meaning less shared space and more efficient use of the property [28]. - Safety is enhanced in corner units, as they are often located on lower floors, providing better stability during emergencies [28]. - The larger area of corner units allows for more flexible space configurations, accommodating larger families or multiple generations [28]. Group 4: Considerations for Choosing Middle Units - For buyers with limited budgets opting for middle units, it is crucial to prioritize ventilation by selecting units that face north to improve air circulation [28]. - Attention should also be given to lighting conditions to ensure adequate natural light in the living spaces [28].
