Core Viewpoint - The article discusses the decline of the "high-end" perception of the one-lift-two-house residential model, highlighting various issues that have led to its poor market performance and the challenges faced by homeowners in this segment [1][20]. Group 1: Elevator Issues - The primary selling point of one-lift-two-house residences is their claimed privacy and quietness, but in reality, residents face significant elevator wait times, averaging 12.7 minutes daily, which accumulates to over 77 hours annually [4][3]. - During peak hours, elevator congestion becomes a major inconvenience, exacerbated by occasional power outages and maintenance, particularly affecting families with elderly members or children [5][3]. Group 2: Shared Area Concerns - Developers often obscure the high shared area ratio in one-lift-two-house models, leading to a situation where buyers pay for a significant amount of unusable space, with actual usable area potentially being only 65 square meters out of a 100 square meter purchase [8][6]. - Compared to two-lift-four-house models, which have a more reasonable shared area ratio, one-lift-two-house residences present a poor value proposition, leading to buyer dissatisfaction [8][6]. Group 3: Market Challenges - One-lift-two-house properties are difficult to sell, with an average listing time of 187 days, nearly double that of standard homes at 93 days, due to perceived low value for money among potential buyers [12][10]. - High prices and large areas deter many potential buyers, resulting in these properties becoming "dead assets" in the market [14][10]. Group 4: Hidden Costs - Homeowners often overlook ongoing costs associated with one-lift-two-house residences, such as property management fees and maintenance costs, which can significantly increase overall expenses over time [16][14]. - For example, a property with a high shared area can lead to an additional annual property fee of around 2000 yuan, further straining homeowners' finances [16][14]. Group 5: Community Dynamics - The design of one-lift-two-house residences, intended to enhance privacy, ironically leads to a lack of community interaction, with residents reporting a significantly lower neighborhood engagement index compared to standard housing [18][5]. - Studies indicate that residents in these homes face a 27.5% higher risk of depression, particularly affecting vulnerable groups like the elderly and homemakers [18][5]. Group 6: Policy Trends - Regulatory standards are tightening, limiting the viability of one-lift-two-house models, with new guidelines requiring at least two elevators for buildings over 12 stories, signaling a potential phase-out of this housing type [19][18]. - Developers are shifting focus towards more practical and community-oriented housing designs, moving away from the previously favored "high-end" models [19][18].

Group 1 - The concept of "one ladder two households" refers to a building design where two households share one staircase, with specific requirements for the number of elevators based on the number of floors [1] - Common configurations include two elevators (one for passengers and one for fire safety) and two staircases, often referred to as "two ladders two households" [1] - Despite some advantages, such as privacy and ventilation, the design has significant drawbacks, including high shared area costs and potential difficulties in resale [3][4] Group 2 - Key issues with "one ladder two households" include poor living experience due to privacy concerns, low elevator efficiency during peak times, limited natural light, and high shared area costs [3] - Resale challenges arise from low market acceptance, weak appreciation potential, and high maintenance costs, leading to financial strain for some homeowners [3] - Neighborly disputes and design flaws from developers further exacerbate the living conditions, making it essential for buyers to carefully consider their needs before purchasing [3] Group 3 - The price of "one ladder two households" is often higher due to its classification as a small high-rise or villa, which is seen as a desirable option for home improvement [4] - The design typically does not significantly impact lighting, as these buildings are not excessively tall, and the average number of households per elevator is lower compared to high-rise buildings [4][6] - The overall market dynamics for resale are consistent across the second-hand housing market, rather than being solely dependent on the property type [4]
