Why building more units isn't enough: the quality trap
The single most common mistake in failed public housing is prioritizing the number of units built over the quality of those units. A 2024 study in Nigeria measured indoor conditions in public housing and found that in many buildings, indoor air temperature and relative humidity regularly exceeded acceptable limits—28°C and 70% relative humidity—directly harming indoor air quality and livability [1]. The same study surveyed 351 households and built environment experts and concluded that focusing only on housing quantity, while ignoring factors like appropriate design for air quality, high-quality building materials, adequate project financing, and project management expertise, guarantees failure [1]. This finding is echoed across multiple studies: a systematic review of public housing in Kebbi State, Nigeria, identified affordability, sustainability, and effective land use as key determinants of success, not just the number of units [5].
The lesson is clear: a housing project that delivers thousands of units that are too hot, too humid, or poorly constructed is not a success—it is a costly failure. Successful projects start with a definition of success that includes livability and durability.
The long game: maintenance and coordinated governance
Even well-built housing fails if it is not maintained. A 2026 study on building maintenance for Malaysian public housing used a rigorous two-stage process—a systematic review of 35 articles followed by a three-round Delphi expert panel—to identify 49 critical success factors for maintenance, organized into eight categories [4]. The most critical factors were human and financial capital, but experts also highlighted the previously underappreciated importance of physical asset degradation and strict legislative compliance [4]. This means that successful public housing requires not just a good initial build, but a permanent system for upkeep, with dedicated funding and clear legal requirements.
Coordination among stakeholders is equally vital. A 2022 study of affordable high-rise public housing in Malaysia surveyed 170 construction stakeholders and found that the top success factors included good site management and supervision, good communication and coordination, and clear objectives and goals [7]. Failed projects, by contrast, often suffer from fragmented governance, where government agencies, private developers, and communities do not collaborate effectively [5]. The evidence consistently shows that successful public housing is not a one-time construction project—it is an ongoing partnership that requires skilled management, stable funding, and a commitment to maintenance from day one.
