Boxable Casita Prefabricated Home

The Boxabl Casita is a revolutionary prefabricated modular home designed to redefine the concept of modern housing. Built for fast deployment, high energy efficiency, and long-term durability, the Casita is a compact yet luxurious dwelling perfect for backyard accessory units, guest houses, or standalone homes.

The Chilean firm Max Núñez Arquitectos designed a prefabricated steel residence elevated on columns in the Sierra Nevada mountains of southern Chile, drawing comparisons to a “lunar lander.”

Named Casa en los Árboles (House in the Trees), the project was finalized in 2023 on the edge of Conguillío National Park in the Andes. Situated near the active volcanoes Llaima and Lonquimay, the 110-square-metre (1,185-square-foot) dwelling occupies a spot favored for backcountry skiing among forests of araucarias, coihues, raulíes, and oaks.

Modular Buildings, Sky-Building Machines, and Construction Robots

With rapid advances in technology, modern construction sites look very different from the dusty, labor-intensive places of the past. Today, many sites resemble high-tech hubs, equipped with automation and smart machinery.

Modular buildings, sky-building machines, and construction robots are transforming the industry—boosting productivity and making what once seemed impossible, like “mass-producing houses,” a practical reality.

New Modular Systems for High-Rise Buildings

High-rise buildings are starting to use modular construction — which means the building is made from factory-built “blocks” or modules, then stacked and joined together at the site, like giant Lego. This method makes construction faster, cleaner, and often cheaper.

There are two main types of modules:

• Steel modules: They’re lightweight, easy to move, and quick to connect. They’re good for flexible layouts and open spaces.

• Concrete modules: They’re heavier, but very strong, durable, and fire-resistant, which makes them better for long-lasting homes.

Researchers are now testing new hybrid modules that combine steel and concrete. These give the benefits of both: they’re strong, safe, fire-resistant, and still light enough to build quickly. Special fast-joining techniques are being developed so workers can connect these modules securely in less time.

Factories are also looking at automation (robots, machines, precision tools) to make modules faster, more accurate, and more customizable. This means future skyscrapers could be built more safely, more sustainably, and in much less time than with traditional methods.

LG Expands Its Smart Cottage Series With Budget-Friendly Modular Homes

On October 2, LG Electronics introduced new additions to its LG Smart Cottage lineup — affordable modular homes designed to meet the needs of people embracing flexible lifestyles such as “Five Urban, Two Rural Days” and “Workation” (a combination of work and vacation).

Modular homes are built from prefabricated sections, or “modules,” that are manufactured in a factory and then assembled on-site, offering faster construction and consistent quality.

The new lineup features two models: the MONO Core 27, an open-plan 27㎡ (8-pyeong) single-story unit, and the MONO Core 54, a larger 54㎡ (16-pyeong) single-story layout with separated spaces. With these additions, LG’s Smart Cottage range now includes six different types — available in both one- and two-story configurations and sizes of 8, 14, and 16 pyeong.

Robotic Modular Factories Planned Across UAE, Europe, and US by Mulk Marses Robotics

Automated wall panel and pod production set for global rollout

Mulk International — the global arm of UAE-based Mulk Holdings International — has joined forces with Marses to launch Mulk Marses Robotics, a new venture aimed at fast-tracking the adoption of automated modular construction worldwide.

Expanding modular automation

The company intends to set up fully automated modular factories in the UAE, Europe, and the United States. These facilities will employ advanced robotic systems to mass-produce wall panels, bathroom pods, and modular building elements. By embracing industrialized methods, the joint venture aims to cut costs, shorten project delivery times, and ensure consistent quality.

Understanding Shape Imperfections in Modular Construction

When buildings are made the old-fashioned way, small mistakes in size or shape (like a wall leaning slightly or a column not being perfectly straight) are expected. Engineers know how to calculate these errors when checking if the building is safe.

But in Modular Integrated Construction (MiC), buildings are made from factory-built modules. These modules are very precise, but they still aren’t perfect. Even tiny factory errors, plus bumps during transportation and installation, can make modules slightly bent, tilted, or misaligned. These little mistakes are called initial geometric imperfections.

The problem is, old building design methods don’t work well for MiC because they focus on single pieces (like just one column), not on the whole module. If engineers ignore how these small errors add up across a module, they could design a structure that doesn’t behave as expected.

So, this study created mathematical models to connect small factory errors with the overall module shape problems. They tested these models using computer simulations (Monte Carlo simulations) to predict how much a module might be “off” in real life. With this, engineers can:

• Know how precise factories need to be when making modules.

• Reduce wasted time and rework from mistakes.

• Design safer, more efficient modular buildings.

Fire impact on the structural safety of modular buildings

This research looks at how modular buildings (buildings made from factory-built “boxes” that are put together on-site) behave in a fire.

Scientists wanted to see:

• How long these buildings can survive in a fire,

• What parts of the building fail first,

• And what happens when fire spreads from one room to another.

They tested this using computer models and math simulations instead of burning a real full-size building (which would be way too expensive).

Key things they found

1. The strong columns help a lot 

The buildings use special columns called CFST columns (concrete-filled steel tubes).

• The steel tube on the outside heats up,

• But the concrete inside slows down the heat and keeps it strong.

• This makes the building more fire-resistant than normal steel columns.

2. Where the fire starts matters

• Corner fires are more dangerous because there are fewer other parts of the building to help carry the load.

• Lower floor fires are also worse because those floors are holding up all the weight above them.
