To spur the construction of affordable, resilient homes, the future is concrete
Pablo Moyano Fernández, Washington University in St. Louis Wood is, by far, the most common material used in the U.S. for single-family home construction. But wood construction isn’t engineered for long-term durability, and it often underperforms, particularly in the face of increasingly common extreme weather events. In response to these challenges, I believe mass-produced concrete homes can offer affordable, resilient housing in the U.S. By leveraging the latest innovations of the precast concrete industry, this type of homebuilding can meet the needs of a changing world.
Wood’s rise to power
Over 90% of the new homes built in the U.S. rely on wood framing. Wood has deep historical roots as a building material in the U.S., dating back to the earliest European settlers who constructed shelters using the abundant native timber. One of the most recognizable typologies was the log cabin, built from large tree trunks notched at the corners for structural stability.Log cabins were popular in the U.S. during the 18th and 19th centuries.Heritage Art/Heritage Images via Getty Images In the 1830s, wood construction underwent a significant shift with the introduction of balloon framing. This system used standardized, sawed lumber and mass-produced nails, allowing much smaller wood components to replace the earlier heavy timber frames. It could be assembled by unskilled labor using simple tools, making it both accessible and economical. In the early 20th century, balloon framing evolved into platform framing, which became the dominant method. By using shorter lumber lengths, platform framing allowed each floor to be built as a separate working platform, simplifying construction and improving its efficiency. The proliferation and evolution of wood construction helped shape the architectural and cultural identity of the nation. For centuries, wood-framed houses have defined the American idea of home – so much so that, even today, when Americans imagine a house, they typically envision one built of wood.A suburban housing development from the 1950s being built with platform framing.H. Armstrong Roberts/ClassicStock via Getty Images Today, light-frame wood construction dominates the U.S. residential market. Wood is relatively affordable and readily available, offering a cost-effective solution for homebuilding. Contractors are familiar with wood construction techniques. In addition, building codes and regulations have long been tailored to wood-frame systems, further reinforcing their prevalence in the housing industry. Despite its advantages, wood light-frame construction presents several important limitations. Wood is vulnerable to fire. And in hurricane- and tornado-prone regions, wood-framed homes can be damaged or destroyed. Wood is also highly susceptible to water-related issues, such as swelling, warping and structural deterioration caused by leaks or flooding. Vulnerability to termites, mold, rot and mildew further compromise the longevity and safety of wood-framed structures, especially in humid or poorly ventilated environments.
The case for concrete
Meanwhile, concrete has revolutionized architecture and engineering over the past century. In my academic work, I’ve studied, written and taught about the material’s many advantages. The material offers unmatched strength and durability, while also allowing design flexibility and versatility. It’s low-cost and low-maintenance, and it has high thermal mass properties, which refers to the material’s ability to absorb and store heat during the day, and slowly release it during the cooler nights. This can lower heating and cooling costs. Properly designed concrete enclosures offer exceptional performance against a wide range of hazards. Concrete can withstand fire, flooding, mold, insect infestation, earthquakes, hail, hurricanes and tornadoes. It’s commonly used for home construction in many parts of the world, such as Europe, Japan, Mexico, Brazil and Argentina, as well as India and other parts of Southeast Asia. However, despite their multiple benefits, concrete single-family homes are rare in the U.S. That’s because most concrete structures are built using a process called cast-in-place. In this technique, the concrete is formed and poured directly at the construction site. The method relies on built-in-place molds. After the concrete is cast and cured over several days, the formwork is removed. This process is labor-intensive and time-consuming, and it often produces considerable waste. This is particularly an issue in the U.S., where labor is more expensive than in other parts of the world. The material and labor cost can be as high as 35% to 60% of the total construction cost. Portland cement, the binding agent in concrete, requires significant energy to produce, resulting in considerable carbon dioxide emissions. However, this environmental cost is often offset by concrete’s durability and long service life. Concrete’s design flexibility and structural integrity make it particularly effective for large-scale structures. So in the U.S., you’ll see it used for large commercial buildings, skyscrapers and most highways, bridges, dams and other critical infrastructure projects. But when it comes to single-family homes, cast-in-place concrete poses challenges to contractors. There are the higher initial construction costs, along with a lack of subcontractor expertise. For these reasons, most builders and contractors stick with what they know: the wood frame.
A new model for home construction
Precast concrete, however, offers a promising alternative. Unlike cast-in-place concrete, precast systems allow for off-site manufacturing under controlled conditions. This improves the quality of the structure, while also reducing waste and labor. The CRETE House, a prototype I worked on in 2017 alongside a team at Washington University in St. Louis, showed the advantages of a precast home construction. To build the precast concrete home, we used ultra-high-performance concrete, one of the latest advances in the concrete industry. Compared with conventional concrete, it’s about six times stronger, virtually impermeable and more resistant to freeze-thaw cycles. Ultra-high-performance concrete can last several hundred years. The strength of the CRETE House was tested by shooting a piece of wood at 120 mph (193 kph) to simulate flying debris from an F5 tornado. It was unable to breach the wall, which was only 2 inches (5.1 centimeters) thick.The wall of the CRETE House was able to withstand a piece of wood fired at 120 mph (193 kph). Building on the success of the CRETE House, I designed the Compact House as a solution for affordable, resilient housing. The house consists of a modular, precast concrete system of “rings” that can be connected to form the entire structure – floors, walls and roofs – creating airtight, energy-efficient homes. A series of different rings can be chosen from a catalog to deliver different models that can range in size from 270 to 990 square feet (25 to 84 square meters). The precast rings can be transported on flatbed trailers and assembled into a unit in a single day, drastically reducing on-site labor, time and cost. Since they’re built using durable concrete forms, the house can be easily mass-produced. When precast concrete homes are mass-produced, the cost can be competitive with traditional wood-framed homes. Furthermore, the homes are designed to last far beyond 100 years – much longer than typical wood structures – while significantly lowering utility bills, maintenance expenses and insurance premiums. The project is also envisioned as an open-source design. This means that the molds – which are expensive – are available for any precast producer to use and modify.The Compact House is made using ultra-high-performance concrete.Pablo Moyano Fernández, CC BY-SA
Leveraging a network that’s already in place
Two key limitations of precast concrete construction are the size and weight of the components and the distance to the project site. Precast elements must comply with standard transportation regulations, which impose restrictions on both size and weight in order to pass under bridges and prevent road damage. As a result, components are typically limited to dimensions that can be safely and legally transported by truck. Each of the Compact House’s pieces are small enough to be transported in standard trailers. Additionally, transportation costs become a major factor beyond a certain range. In general, the practical delivery radius from a precast plant to a construction site is 500 miles (805 kilometers). Anything beyond that becomes economically unfeasible. However, the infrastructure to build precast concrete homes is already largely in place. Since precast concrete is often used for office buildings, schools, parking complexes and large apartments buildings, there’s already an extensive national network of manufacturing plants capable of producing and delivering components within that 500-mile radius. There are other approaches to build homes with concrete: Homes can use concrete masonry units, which are similar to cinder blocks. This is a common technique around the world. Insulated concrete forms involve rigid foam blocks that are stacked like Lego bricks and are then filled with poured concrete, creating a structure with built-in insulation. And there’s even 3D-printed concrete, a rapidly evolving technology that is in its early stages of development. However, none of these use precast concrete modules – the rings in my prototypes – and therefore require substantially longer on-site time and labor. To me, precast concrete homes offer a compelling vision for the future of affordable housing. They signal a generational shift away from short-term construction and toward long-term value – redefining what it means to build for resilience, efficiency and equity in housing.An image of North St. Louis, taken from Google Earth, showing how vacant land can be repurposed using precast concrete homes.Pablo Moyano Fernández, CC BY-SAThis article is part of a series centered on envisioning ways to deal with the housing crisis.Pablo Moyano Fernández, Assistant Professor of Architecture, Washington University in St. Louis This article is republished from The Conversation under a Creative Commons license.

Doing things alone is on the rise, and businesses should pay more attention to that – even on Valentine’s Day
Peter McGraw discusses the increasing prevalence of solo living and its implications for businesses, particularly during Valentine’s Day, which typically emphasizes couples. Despite many individuals enjoying activities alone, the marketplace often neglects this growing demographic. Recognizing and catering to solo consumers can yield significant opportunities for businesses.
Doing things alone is on the rise, and businesses should pay more attention to that – even on Valentine’s Day
Every February, Valentine’s Day amplifies what single people already know – that public life is built for two. Restaurants roll out prix fixe menus for couples. Hotels promote “romantic getaway” packages designed for double occupancy. A table for one still invites the question, “Just you?”
Yet there’s irony that’s hard to miss. While Valentine’s Day doubles down on togetherness, more adults are living – and moving through the world – alone.
As a behavioral economist, I study what I call the “solo economy.” A growing share of economic life today is organized around people who live, spend and make decisions on their own.
1-person households aren’t outliers
Half of U.S. adults are unmarried, and one-person households are now the nation’s most common living arrangement. This isn’t a temporary phase confined to young adults waiting to settle down. It includes never-married professionals, divorced empty nesters, widows and widowers, and people who simply prefer to live independently.
It’s a slow-moving demographic shift away from long-term partnership as the dominant adult life path, but a consequential one – reshaping everything from housing and travel to social policy and commerce. One of its clearest expressions is the number of people doing things alone in public.
The rise of public solo life
It would be one thing if the economy were built for two and solos stayed home. But they are going to museums, traveling and, of course, dining alone in restaurants. To assess this behavior, I surveyed single and married Americans about their participation in 25 activities that occur in public – from shopping and dining to attending movies and concerts.
The pattern was striking. Overall, singles were much more likely to do things alone in public than their married counterparts – 56% versus 39%. The difference held across every activity I measured.

The biggest gaps weren’t for practical tasks like grocery shopping. They were for leisure experiences like going to the movies, dining out and attending concerts. In fact, seven of the 10 largest differences involved retail or entertainment settings – the very places most designed and marketed with couples in mind.
Why hasn’t the business world paid more attention to the singles market?
The answer lies in psychology. Some reluctance stems from the belief that other customers will perceive solo diners or moviegoers as sad or lonely. These fears are amplified by what psychologists call the spotlight effect – our tendency to overestimate how much other people notice and judge us.
Findings by consumer researchers Rebecca Hamilton and Rebecca Ratner can help explain why this bias is so persistent. Across studies conducted in the U.S., China and India, people consistently predicted they would enjoy activities less if they did them alone – even though they’d be seeing the same movie or visiting the same museum.
But when people actually went alone, they enjoyed the experience just as much as those who went with others. The fear, it turns out, is largely imagined.
Another problem is that solo consumers don’t always feel welcome.
While behavior is changing, markets have been slower to adapt. Most businesses still design experiences around pairs, families or groups. Consider restaurants that seat solo diners at the bar or near the kitchen or bathrooms, or ticketing systems that require purchasing in pairs. The result is friction for solo consumers – and missed opportunities for companies.
Valentine’s Day promotions make that mismatch especially visible. In 2024, IKEA Canada offered a Valentine’s Day dining experience in its showroom priced and designed for two – and only two – people.
After backlash, the company revised the promotion the following year to be more inclusive: “Bring a loved one, a good friend, or the whole family.” It was a small change, but a revealing one.

Why solo shoppers have outsized influence
Solo consumers represent a large, growing and profitable market segment, yet they’re navigating a marketplace that still treats them as edge cases.
Another study that Ratner conducted with business school professor Yuechen Wu adds an important twist.
Analyses of more than 14,000 Tripadvisor reviews of restaurants and museums show that reviews written by solo diners and solo museumgoers are rated as more helpful – and receive more positive feedback – than reviews written by people who went with others.
Follow-up experiments showed that when otherwise identical recommendations differed only in whether the reviewer experienced the activity alone or with others, respondents were more likely to rely on the solo reviewer when deciding what to do.
Why? Observers infer that people who go alone are more genuinely interested in the experience and more focused on its quality, rather than simply going along with someone else’s preferences.
Being alone, it turns out, functions as a credibility cue. For businesses, that means solo customers aren’t just customers − they can be very influential customers.
Designing for 1 in Asia
Asian businesses are far ahead of the West in recognizing the buying power of people doing things alone.
In South Korea, for example, “honjok,” which translates as “alone tribe,” culture has fueled products and services designed explicitly for solo living. Think single-serve meals at convenience stores, one-person karaoke booths, and restaurants that promise judgment-free service.
Similarly, in Japan, the ramen chain Ichiran built its brand around the idea of “flavor concentration,” which encourages diners to eat alone in private booths.
Officially, the design is meant to eliminate distractions and heighten the dining experience. In practice, it does something more important: It legitimizes solo dining.

Progress in the US
In the U.S., Disney theme parks and some of the company’s competitors have long used single-rider lines that reward solo visitors with shorter waits, turning independence into operational efficiency – a logic ski resorts adopted decades ago to fill empty seats on chairlifts.
And solo tourism has become a major trend. Demand is growing, and tour operators are adapting offerings to meet it, including specialized tours for singles and adjustments to historically prohibitive pricing practices.
Industry analysis also shows the global solo travel market expanding rapidly, with tailored products and experiences emerging worldwide. Some companies now offer dedicated solo travel collections with no single supplement − the extra fee traditionally charged to travelers who occupy a room alone − and tours designed specifically for independent travelers.
Doing things alone is an opportunity
Valentine’s Day offers a chance to see how outdated many widespread assumptions still are.
It treats solitude as a problem to be solved, even as people’s behavior tells a different story. Yet businesses, policymakers and U.S. culture more broadly have not designed a world that fully acknowledges that about 42% of American adults are single.
In the meantime, singles aren’t waiting at home. They’re out there – at the movies, on planes, in museums and restaurants – moving through public life on their own terms.
Valentine’s Day may always be built for two. But the economy won’t be.
Chinamaxxing: The Viral Trend Turning Geopolitics Into Aesthetic Fantasy
A viral social media trend called “Chinamaxxing” is turning geopolitics into aesthetic comparison—revealing more about generational frustration than China itself.
Clean subways gliding into spotless stations. Neon skylines glowing at night. Clips of high-speed trains, cashless stores, orderly crowds. Overlaid text reads something like, “Meanwhile in China…” or “They figured it out.”
This is “Chinamaxxing,” a loosely defined but increasingly visible social media trend where mostly young users frame China as a model of efficiency, stability, and modernity—often in contrast to life in the West.
What makes the trend notable isn’t just its subject, but its tone. Chinamaxxing is rarely explicit political advocacy. It’s not a manifesto. It’s a mood. Aesthetic admiration blended with subtle critique, delivered through short, visually compelling clips that invite comparison without context.
And that’s precisely why it has sparked debate.
What Is “Chinamaxxing,” Really?
Despite the provocative name, Chinamaxxing isn’t a coordinated movement or ideology. It’s better understood as an algorithm-driven pattern—a recurring style of content that rewards certain visuals and emotional cues.
Most Chinamaxxing content emphasizes:
Infrastructure and urban design
Technology embedded in daily life
Perceived order and efficiency
Implicit contrast with Western dysfunction
What it typically omits:
Political repression and censorship
State surveillance
Limits on speech and dissent
The lived diversity of Chinese experiences
The result is a highly curated portrayal—less about China as a nation, and more about what viewers want to believe is possible somewhere else.
Why It’s Gaining Traction Now
The rise of Chinamaxxing says as much about the West as it does about China.
For many young users, particularly Gen Z, the backdrop is familiar: rising housing costs, student debt, healthcare anxiety, political polarization, and a growing sense that institutions no longer function as promised.
In that environment, visually persuasive content showing order and functionality carries emotional weight. It offers relief from chaos—real or perceived.

Social platforms amplify this effect. Short-form video rewards clarity, contrast, and immediacy. A clean subway platform communicates more in five seconds than a policy analysis ever could. Nuance does not trend well. Aesthetics do.
The Social and Political Criticism
Critics argue Chinamaxxing crosses a line from curiosity into distortion.
By focusing exclusively on infrastructure and surface-level efficiency, the trend risks:
Normalizing authoritarian governance through lifestyle framing
Reducing political systems to consumer experiences
Ignoring the tradeoffs that make such systems possible
Supporters counter that Western media has long flattened China into a single negative narrative, and that admiration for specific aspects of another society is not the same as endorsing its government.
Both perspectives, however, miss something important.
What the Trend Actually Reveals
Chinamaxxing isn’t primarily about China. It’s about disillusionment.
It reflects a generation that:
Feels let down by existing systems
Engages politics emotionally rather than institutionally
Uses visual culture to express dissatisfaction indirectly
In this context, China becomes a projection surface—not because it is perfect, but because it appears functional.
That distinction matters.
Why This Matters
Chinamaxxing highlights how political understanding is evolving in the digital age. Governance is increasingly consumed not through debate or civic participation, but through comparison clips, memes, and aesthetics.
The risk isn’t admiration. It’s oversimplification.
When complex societies are reduced to visuals alone, public discourse loses depth. But when those visuals resonate, they also signal real unmet needs: stability, competence, and trust in institutions.

Ignoring that signal would be a mistake.
The STM Daily News Perspective
Chinamaxxing is not an endorsement, a conspiracy, or a joke. It is a cultural artifact—one that reflects generational anxiety, algorithmic storytelling, and the widening gap between expectations and reality.
The question it raises isn’t whether China is better.
It’s why so many people feel their own systems are no longer working.
Stay tuned to STM Daily News for more stories exploring internet culture, social media trends, and how digital platforms shape public perception. We’ll be publishing in-depth pieces that break down the societal impact of viral phenomena like Chinamaxxing, the psychology behind online political trends, and the evolving language of Gen Z culture.

What if universal rental assistance were implemented to deal with the housing crisis?
A significant number of American families facing unaffordable rents are living in motels. While many believe a housing shortage causes high rents, experts suggest that expanding rental assistance is more effective. Making subsidies available to all eligible low-income households could tackle this affordability crisis significantly.
Rents and home prices would fall, the argument goes, if rules such as minimum lot- and house-size requirements and prohibitions against apartment complexes were relaxed. This, in turn, would make it easier to build more housing.
As experts on housingpolicy, we’re concerned about housing affordability. But our research shows little connection between a shortfall of housing and rental affordability problems. Even a massive infusion of new housing would not shrink housing costs enough to solve the crisis, as rents would likely remain out of reach for many households.
However, there are already subsidies in place that ensure that some renters in the U.S. pay no more than 30% of their income on housing costs. The most effective solution, in our view, is to make these subsidies much more widely available.
A financial sinkhole
Just how expensive are rents in the U.S.?
According to the U.S. Department of Housing and Urban Development, a household that spends more than 30% of its income on housing is deemed to be cost-burdened. If it spends more than 50%, it’s considered severely burdened. In 2023, 54% of all renters spent more than 30% of their pretax income on housing. That’s up from 43% of renters in 1999. And 28% of all renters spent more than half their income on housing in 2023.
Renters with low incomes are especially unlikely to afford their housing: 81% of renters making less than $30,000 spent more than 30% of their income on housing, and 60% spent more than 50%.
Estimates of the nation’s housing shortage vary widely, reaching up to 20 million units, depending on analytic approach and the time period covered. Yet our research, which compares growth in the housing stock from 2000 to the present, finds no evidence of an overall shortage of housing units. Rather, we see a gap between the number of low-income households and the number of affordable housing units available to them; more affluent renters face no such shortage. This is true in the nation as a whole and in nearly all large and small metropolitan areas.
Would lower rents help? Certainly. But they wouldn’t fix everything.

We ran a simulation to test an admittedly unlikely scenario: What if rents dropped 25% across the board? We found it would reduce the number of cost-burdened renters – but not by as much as you might think.
Even with the reduction, nearly one-third of all renters would still spend more than 30% of their income on housing. Moreover, reducing rents would help affluent renters much more than those with lower incomes – the households that face the most severe affordability challenges.
The proportion of cost-burdened renters earning more than $75,000 would fall from 16% to 4%, while the share of similarly burdened renters earning less than $15,000 would drop from 89% to just 80%. Even with a rent rollback of 25%, the majority of renters earning less than $30,000 would remain cost-burdened.
Vouchers offer more breathing room
Meanwhile, there’s a proven way of making housing more affordable: rental subsidies.
In 2024, the U.S. provided what are known as “deep” housing subsidies to about 5 million households, meaning that rent payments are capped at 30% of their income.
These subsidies take three forms: Housing Choice Vouchers that enable people to rent homes in the private market; public housing; and project-based rental assistance, in which the federal government subsidizes the rents for all or some of the units in properties under private and nonprofit ownership.
The number of households participating in these three programs has increased by less than 2% since 2014, and they constitute only 25% of all eligible households. Households earning less than 50% of their area’s median family income are eligible for rental assistance. But unlike Social Security, Medicare or food stamps, rental assistance is not an entitlement available to all who qualify. The number of recipients is limited by the amount of funding appropriated each year by Congress, and this funding has never been sufficient to meet the need.
By expanding rental assistance to all eligible low-income households, the government could make huge headway in solving the rental affordability crisis. The most obvious option would be to expand the existing Housing Choice Voucher program, also known as Section 8.
The program helps pay the rent up to a specified “payment standard” determined by each local public housing authority, which can set this standard at between 80% and 120% of the HUD-designated fair market rent. To be eligible for the program, units must also satisfy HUD’s physical quality standards.
Unfortunately, about 43% of voucher recipients are unable to use it. They are either unable to find an apartment that rents for less than the payment standard, meets the physical quality standard, or has a landlord willing to accept vouchers.

Renters are more likely to find housing using vouchers in cities and states where it’s illegal for landlords to discriminate against voucher holders. Programs that provide housing counseling and landlord outreach and support have also improved outcomes for voucher recipients.
However, it might be more effective to forgo the voucher program altogether and simply give eligible households cash to cover their housing costs. The Philadelphia Housing Authority is currently testing out this approach.
The idea is that landlords would be less likely to reject applicants receiving government support if the bureaucratic hurdles were eliminated. The downside of this approach is that it would not prevent landlords from renting out deficient units that the voucher program would normally reject.
Homeowners get subsidies – why not renters?
Expanding rental assistance to all eligible low-income households would be costly.
The Urban Institute, a nonpartisan think tank, estimates it would cost about $118 billion a year.
However, Congress has spent similar sums on housing subsidies before. But they involve tax breaks for homeowners, not low-income renters. Congress forgoes billions of dollars annually in tax revenue it would otherwise collect were it not for tax deductions, credits, exclusions and exemptions. These are known as tax expenditures. A tax not collected is equivalent to a subsidy payment.Only about 25% of eligiblge households receive rental assistance from the federal government. Luis Sinco/Los Angeles Times via Getty Images
For example, from 1998 through 2017 – prior to the tax changes enacted by the first Trump administration in 2017 – the federal government annually sacrificed $187 billion on average, after inflation, in revenue due to mortgage interest deductions, deductions for state and local taxes, and for the exemption of proceeds from the sale of one’s home from capital gains taxes. In fiscal year 2025, these tax expenditures totaled $95.4 billion.
Moreover, tax expenditures on behalf of homeowners flow mostly to higher-income households. In 2024, for example, over 70% of all mortgage-interest tax deductions went to homeowners earning at least $200,000.
Broadening the availability of rental subsidies would have other benefits. It would save federal, state and local governments billions of dollars in homeless services. Moreover, automatic provision of rental subsidies would reduce the need for additional subsidies to finance new affordable housing. Universal rental assistance, by guaranteeing sufficient rental income, would allow builders to more easily obtain loans to cover development costs.
Of course, sharply raising federal expenditures for low-income rental assistance flies in the face of the Trump administration’s priorities. Its budget proposal for the next fiscal year calls for a 44% cut of more than $27 billion in rental assistance and public housing.
On the other hand, if the government supported rental assistance in amounts commensurate with the tax benefits given to homeowners, it would go a long way toward resolving the rental housing affordability crisis.
