What Are Prefabricated Buildings and Why Are They Gaining Popularity?

prefabricated building

Have you been in construction lately? So, are you wondering what are prefabricated buildings? Are they better than your traditional form of construction? Should you go for a modular house now that everything is becoming so contemporary? 

It has been estimated that about 10% of Australian homes will be prefabricated constructionsby 2023. These are literally a game-changer in the construction industry, not just because they look sleek and pleasing, but because they are fast, efficient, durable, and eco-friendly. Whether you are thinking of building a home, a government building, a hospital or even a school, prefab has become the ultimate sustainable building materialsolution.

People still assume that prefab homes mean boring matchbox houses; those days are gone. Prefabricated homesare a modern housing solution now, which are architectural marvels, combining style with substance and speed with quality. So, are you curious about the world of prefab? Well, we have got you covered.

In this blog, we will walk you through everything you need to know about prefabโ€” fromwhat are prefabricated buildingsto why they are even in the market. Ready for an adventure with UNIBUILD? Letโ€™s get into it!

What are Prefabricated Buildings? Your Construction Crash Course

Breaking down the basics of construction for you-

What are prefabricated buildings?

Prefabricated buildings, commonly referred to as โ€œprefabโ€, are buildings that are manufactured externally off the construction site in a controlled factory environment, and then they are taken to the site for assembling it together. The whole process of assembling pre-manufactured components, along with transportation and creation, is known as prefabrication.

Unlike the traditional method, where the process happens on-site step by step, prefabricated constructionbreaks that process into pieces and allows multiple points of the process to happen at the same time. The level of prefabrication can vary from complete volumetric modules to panelised systems or structural components like walls, floors, and roofs.

These prefabricated buildingsare typically seen as residential homes (single and multi-units), commercial spaces like offices and malls, institutional buildings, and industrial buildings like warehouses, and are often used for disaster relief shelters.

Why are Prefabricated Constructions getting so popular?

Letโ€™s unpack some benefits of prefab homes.

Cost-effective Construction

  • Prefabricated construction is cheap for the most part. The entire process happens simultaneously, which significantly reduces the labour costs, plus you build prefabfrom mass-produced components, which also reduces the price of buying supplies as they are done in bulk.
  • The resale value of prefabricated modular buildingsis great, so in the long run, it can be very beneficial. Besides, these are very sturdy and durable, reducing their maintenance costs.

Sustainable Building Material

  • Prefab is extremely eco-friendly. The biggest benefit of prefabricated buildingsis that they support sustainable practices.
  • The components are mass-produced and used in precise measurements; there is controlled waste management. Factories can also reuse off-cuts and implement efficient energy practices.
  • These prefabs also support features like energy-saving insulation methods, solar panels, etc. In comparison to conventional construction, people lean towards prefab if they are environmentally conscious.

Extreme Design Flexibility

  • Modern prefabricated architectureallows for extreme design versatility. The myth that these are just boring box-shaped houses is very old.
  • Modern technologies allow for customisable floor plans, finishes, and facades that reflect any style, from contemporary to minimalist.

Time Efficient

  • The most attractive benefit of prefabricated buildingsis that they significantly reduce the construction time taken. The components are factory-produced which leads to the completion of project atleast 50% faster.

Across the globe, there is a housing crisis; with such benefits, prefab has become a popular choice across multiple industries.

How are prefabricated homes so much cheaper than conventional construction?

Prefabricated buildings are cheaper than conventional ones because they use mass-produced materials and assemble them later. This majorly cuts down on labour costs as well as buying supply costs, as factories get them in bulk. Also, these are built faster.

If I opt to build prefab homes, will there be design limitations?

No, the prefab industry has been completely modernised in the last few decades, making room for limitless design possibilities. You can choose from sleek, contemporary designs to traditional looks, whatever suits you the best.

The UNIBUILD PREFAB TECHNOLOGY was recently nominated for the 2024 SMART BUILDING INDUSTRY AWARDS

90% of the above precast panel load is weightless thermal insulation. 10% of the load is Unibuild steel fibre concrete applied in thin layers surrounding the insulation rendering the panels structural, fireproof and floodproof.

Loading can be maximised for the loaders full capacity. (Four loaders would be required to transport the equivalent house volume of a “factory transportable” building,  requiring escort vehicles and police resource time. and limited travel times.

Prefab UNIBUILD components are less than 2400 mm wide so can travel 24/7 on any road in the country. Short offload time and early structural completion on site in a couple of days is a major plus.

The UNIBUILD Bush-Fire Proof Building Technology.

Back in 1952, when I was a school boy in Canberra, Australia, a raging bush-fire swept in from the south west burning all in its path. The fire burned over Red Hill and was eventually stopped at the fence lines of the residential and foreign embassy homes  lining Mugga Way.

Our gang won the Radio Station 2CA bush fire donations appeal competition, thanks to a 5 pound check from the Dutch Embassy, which unfortunately lost its rear fence.

In 2003, again, a raging bush-fire swept in from the south west. However thousands of houses and other buildings had been built in suburbs south west of Red Hill in the path of the fire front. 500 buildings burned to the ground and 4 deaths recorded.

The bush needs fire for regeneration and fire paths repeat over previous paths. (Has been going on for thousands of years).

Early ACT building regulations insisted on a layer of  tar paper be installed under the floor boards, in the wall cavities and under the roof tiles to limit condensation. (Tar paper consists of a thin layer of bitumen between two layers of brown paper). I physically fixed this tar paper during my days as a carpenter.

According to CSIRO fire research, when the temperature reaches 47.7 degrees C, the oil in eucalyptus leaves turns to flammable gas, and bitumen turns to flammable gas. So when fire surrounded the above houses the tar paper immediately burned causing the structures to explode. If you study TV footage of the Canberra 2003 fire you will see blue flames licking out from the gaps between the roof tiles. These are the flames of hydrocarbons, not burning leaves and small tree branches which burn red and yellow.

The only building material which remained in tact were the concrete paths, steps and posts.

Lately I have been researching the thousands of fire photographs of the recent, and current, bush fire damage to houses and buildings. I visited some of the sites when the King’s Highway reopened for access to the NSW south coast.

Most of the burned structures I investigated were older buildings and would have been lined with tar paper, a building regulation at the time of construction.

I think you can apply the same reasoning to all the other bush fire damaged regions.

Tar paper was later banned from construction regulations yet there are still thousands of older houses and other buildings containing this material still standing.   

LESSON LEARNED. DON’T BUILD HOUSES USING FLAMMABLE  OR NON FIRE-PROOF BUILDING MATERIALS.

In the mid nineties I was licensing The Unibuild Technology into the USA and based in San Diego, California. (Many gum trees grow in California).

One morning I visited a local shopping centre and noticed a small grass fire burning in an open field opposite. That evening the fire spread up a hill and burned down over 500 houses.

The developer of this sub division had a covenant on the house designs. All roofs were to be of Californian redwood shingles. A shingle in northern California has a moisture content above 95%. In southern California the moisture content reduces to about 3%. Thus all the roofs were reduced to firewood kindling.

The only building materials which remained in tact were the concrete paths, steps, posts and the ornamental masonry and concrete fireplace constructions. Concrete does not burn.

LESSON LEARNED. DON’T BUILD HOUSES USING FLAMMABLE OR NON FIRE-PROOF BUILDING MATERIALS.

Back in the 1970’s Unibuild began research into steel fibre reinforced concrete and gradually began using this material in its housing and other building projects, eliminating most traditional flammable building products and associated fixing trades.

Today, all Unibuild structural components for floors, walls, roof and other items are made from steel fibre reinforced concrete, either in solid form or encasing insulation slabs inserted to comply with building R value regulations. Thus the whole building structure is fire proof with a minimum fire rating of two hours, and six hours for the in-built columns and beams.

Bush-fires sweep through in a matter of minutes, and as concrete does not burn the fires cannot find any material in Unibuild structures to ignite and flame. (As a spin off, there is no need to pay exorbitant fire insurance premiums which rise and rise after every national disaster).

Unibuild Off Site Modular Construction Vs. Conventional Construction

The first Unibuild off-site modular home was built in Canberra in 1968. In 1969 we relocated to Perth, Western Australia, and designed and constructed many Unibuild modular masonry buildings requiring the labour of bricklayers. In the early 70’s Western Australia was booming and bricklayers were in short supply. They would quote a job, lay a couple of hundred blocks then demand a review of rates upwards.

Unibuild decided to eliminate the masonry trade in favour of its modular, insulated precast concrete walling components. In a public demonstration we commenced construction of two projects of identical design on the same day. One was the usual Unibuild modular masonry construction, the second was Unibuild’s first precast off-site modular construction. The following photographs show the advantages of Unibuild off-site prefabrication.

UNIBUILD HAS NOT DESIGNED AND BUILT A CONVENTIONAL HOUSE SINCE.

Modular Construction:

  • Takes only a few weeks to complete the entire project on site, depending on size.
  • In the planning stage, off-site components are fully detailed to fit the specific needs of the customer’ project. (Each trade his its own detailed plan).
  • Off-site factory space is used to manufactures all the structural components
  • The only site work carried out are footing pads, sewerage and drainage works completed before the structural components arrive at the site.
  • A crane erects the prefabricated components in 1-2 days. Add doors and windows and lock up after 4-5 days. The job is now weather proof.
  • The interior trades, electrician, plumber and painter can all work together to complete the project.
  • Nil or only minimum scaffolding is required
  • Landscaping, driveways and paving can follow but are not critical trades.

Conventional Construction:

  • Construction takes about 6-12 months or longer.
  • At the planning stage, architects and engineers draw up one overall plan to be sorted out by all the trades. Usually no detailed co-ordination planning.
  • All trades must follow in trade sequence. Drainage lines, ground slab, masonry construction, roof structure, roof tiling, etc. Cost of detailed supervision is high due to chasing up the various trade workers for scheduling.
  • Wet weather can delay the project by months.
  • The building need to be scaffold out around the perimiter, a very costly exercise.
  • More internal trades required, eg. framers and plasterers needing to work in sequence.
  • Landscaping, driveways and paving common to both methods of construction.

Flood Proof Building Technology

If all the houses and low rises buildings damaged and destroyed during the recent Australian floods had been built using The Unibuild flood proof technology they would have remained undamaged and habitable.

Fire Proof Building Technology

The loss of human life and property caused by the recent fires in Australia is regretable. Had the properties been built using The Unibuild Technology most likely all structures would have remained habitable.

To those wishing to rebuild, or build for the first time to prevent fire loss in a future similar event, we offer our fireproof building technology for consideration.

Unibuild fireproof structures comprise the floors, walls and roofs, all components having a minimum 2 hour fire rating to withstand the hottest bush fire as it sweeps through.
