This block-by-block construction has completely changed the construction game. Let us get to know more about prefabrication.

However, Prefabrication is the assembly of buildings or their components at a location aside from the vacant lot. Also, this tactic controls construction costs by economizing on time, wages, and materials. Units that can be Prefabricated may include doors, stairs, window walls, wall panels, floor panels, roof trusses, room-sized components, and even entire buildings.

Prefabrication requires the cooperation of architects, suppliers, and builders regarding the dimensions of basic modular units. Building plans are drafted using 8-foot ceilings, and floor plans are described in multiples of 4. Therefore, prefabricated wall units are built-in wall frames in dimensions of 8 feet high by 4, 8, 16, or 24 feet long. Insulation, plumbing, electrical wiring, ventilation systems, doors, and windows are all constructed to suit the 4 × 8 -foot modular unit.

Another prefabricated unit widely utilized in light construction is the roof truss, which is manufactured and stockpiled consistently with the angle of pitch and horizontal length in 4-foot increments.

Joining Concrete Panels

Joining of Steel Panels

A prefabricated building component that’s mass-produced during a production line is often made in a shorter time for a lower cost than an identical element fabricated by highly paid skilled labourers at a vacant lot. Many contemporary building components also require specialized equipment for construction. Therefore, that can’t economically move from one vacant lot to a different one. Materials that became highly specialized, with attendant fluctuations in price and availability. Often stockpiled at prefabrication shops or factories. Additionally, the standardization of building components makes it possible for construction to require a place. Where the staple is the least expensive.

Perhaps, dilution of responsibility is the major drawback to prefabrication. A unit designed in one area of the country can also be prefabricate in another and shipped to yet a 3rd area. Which can or might not have adequate criteria for inspecting materials that aren’t locally produced. These factors increase the probability of structural failure.

Let’s understand more about prefabrication by looking at some examples:

Avenue South Residences, Singapore, World’s Tallest Skyscraper Example of Prefabricated Buildings

A pair of 56-story skyscrapers in Singapore designed by Architecture studio ADDP is going to built-in 2026 using Prefabricated Prefinished Volumetric Construction, making them the tallest prefabricated buildings in the world.

The site consists of two super-high-rises set against the first backdrop of four-story heritage art deco-inspired apartments and an avenue of grand rain trees. ADDP estimates that around 80% of every housing module is going to be built off-site, with waterproofing, tiling, painting, glazing, cabinetry, plumbing, and electrics completed before being delivered to be “stacked and joined together on-site”. This will enable the project to scale back wastage both on-site and off-site with better control of the assembly processes through a central materials and logistics platform.

It will contain over 1,000 residences and be choppy by a series of 16 pocket sky terraces and larger communal terraces on the 19th and 36th stories. The magnificent 56-story tall skyscrapers have characteristics of pristine elegance and sharp lines including rhythmically located pockets of sky terraces.

Precht’s The Farmhouse Concept Combines Modular Homes With Vertical Farms Example of Prefabricated Buildings

Precht designed The Farmhouse as populations around the world are increasingly becoming city dwellers. Who have lost touch with how their food produced, while food transportation has an increasingly damaging effect on the environment.

The conceptual modular system would allow people to grow food in residential tower blocks to eat or share with their area people. Prefabricated A-frame housing modules made up of cross-laminated timber (CLT) would stacke to supply flexible living spaces. CLT is more sustainable than other low-cost building materials like concrete because it locks within the carbon absorbed by the trees that were grown to form it.

However, each of the module’s walls would make of three layers. An inner layer, facing the house interior, would hold the electricity and pipes with the surface finishes. A layer of structure and insulation would form the centre layer. And also the surface layer would hold all the gardening elements and a water system. As a result, different modules would have different types of external systems. For example, hydroponic units for growing without soil, waste management systems, or solar panels to harness sustainable electricity.

Single-family users would be ready to build their own homes using as many modules as they chose, or taller housing blocks might form by arranging the A-frames into stacked duplexes. However, each duplex would have an open plan living and kitchen space on the bottom floor, with tent-shaped bedrooms on the upper floors. In addition, the outer edges of the tower have balconies.  Growing gardens would arrange in order. That they are either private or communal, with the inverted gaps left between modules providing V-shaped buffer zones between apartments and giving the plants natural light and ventilation.

“Echoes Of Brutalist Architecture” In Oma’s Prefabricated Concrete Tower Example of Prefabricated Buildings

Inn Reinier de Graaf led the planning for a 125 m high apartment house. Which he said represents a replacement era for prefabricated housing. Also, alternating protruding windows, recessed terraces, and a facade of ribbed concrete brushed with aggregate pebbles had included in brutalist architecture.

The tower is a component of the Norra Tornen development in Hagastaden, a replacement district to the north of the Swedish capital. Norra Tornen’s wall-to-floor ratio – the number of external walls compared to the interior floor space – is one. Because the apartments have high ceilings and enormous windows. A typical tower’s wall-to-floor ratio is 0.5. However, as daylight restricted for half the year in Sweden the architect and developer decided to feature taller windows.
