The theme of prefabricated architecture and in concrete, prefabricated houses , are in constant updating, design and incorporation of new capabilities in the face of technological innovations.
The development of new materials, modern techniques and the audacity of more than one construction designer has fostered the development of construction modular housing in an industrialized format, mainly represented in homes modern prefabs or modular that some technicians identify as advanced construction technology for perfect homes.
But… Why buy a house prefabricated? The most opportune answer is in the next image
So, the modern prefab house can be the right choice in many cases.

Manufactured homes are homes built by standardized parts that have been built in one place other than its final location in parcel. In short « houses industrialized «.
Goals! Modern housing requires skills and fast and effective solutions to satisfy certain customer needs with high performance and Satisfactory results in less time, at a lower price affordable and on a cabin model already tested in a rigorous and ideal process.
The modular constructions provide possibilities if we talk so much about manufacturing rigorous as in the execution on site if in practice it is they perform consistently.
The real estate market at the time of selling has a growing affinity towards ecological houses prefabricated and energy efficient in their modular designs that provide in reality some type of houses modular cheap compared to traditional construction.
We must remember that the market not only offers the typical modular wooden house , we already found a long catalog of materials (Aluminum – steel, all kinds of panels, concrete, polycarbonate, pvc, steel... etc) thank you technologies offer us more and more possibilities in resistance and qualities both in the walls, as well as in the roof and their interiors.
As we have said, a house prefabricated modern is that “built under roof in the factory», with modern machinery of construction that in many cases work to the millimeter.
Do not confuse housing prefabricated with the modular one. A house modular is one whose initial design is made up of individual elements; bedroom, bathroom, kitchen, etc, and that, together, form a home habitable .
Departing from the typical standard of gabled housing, As examples of modular design we can identify composition:
Undoubtedly the «game» can generate a great variety of Modular prefab house plans although the reality is that simplicity is the cheaper when buying a property prefab.
The chain production of a home a Once finished, it is what we can call "the container", the housing module is transported in vehicles to the chosen site where the parts – containers will be assembled (Normally, on a screed – base or foundation already made of concrete armed) and thus the construction is completed in a short period of time.
We must remember that the modular house is not a mobile home, it is simply a house built off-site and that's what makes it different mainly from the traditional home built by the man.
Usually manufactured housing modern has multiple assemblies that make up the different rooms to inhabit. This system provides us different advantages that we must analyze…
1.- The conditions of control
More control over the weather, quality control, the improved work supervision, easier access to tools, and a smaller number of deliveries of materials in time derives in a lower cost and architectural quality of the construction. They are palpable advantages that in the works "in situ" it's hard to handle.
2.- Environmental impacts
Reductions in cost and less waste of materials, less water pollution, dust and noise, and less waste of energy in general, although the prefabrication has an additional cost and must be quantified in terms of transportation to the place of location.
3.- More times tablets
Changes can be made to the build sequence, savings in time and improvement of the workflow with which translates into cost reduction.
4.- Less conflicts
When carrying out an assembly of the house in the factory . There is a reduction in labor conflicts before the construction operators and more scheduled work.
5.- Improvement of the materials
From their quality, both in the staging and control, up to reduction of storage space and a fewer losses or misplacements.
6.- Security
Increasing the safety of workers through the reduced exposure to inclement weather, temperature extremes, and ongoing operations or dangerous; better working conditions.
In this sense, both advantages and disadvantages in We already talked about modular housing in the article Houses containers where they also inquired about the cost of the container and the different characteristics of the themselves as well as the construction methodology with an example on video.
We have carried out a small market study to see the prices of manufactured homes that are available the sale (We have not added the wooden houses that can be place in a garden) We have only considered the prefabricated houses made of concrete, metal or wood containing consistent conditions and minimum to live: (Prices indicated without VAT)
| Home models prefab | Area | Rooms – Bathrooms | Main material | Total house price prefab | Average m2 built |
| House 1 | 90 m2 Built | 3 Bedrooms – 2 Bathrooms | Concrete | 124000 Euros | 1377 Euros/m2c |
| House 2 | 220 m2 Built | 5 Bedrooms – 3 Bathrooms | Concrete | 248000 Euros | 1127 Euros/m2c |
| House 3 | 87 m2 Built | 2 Bedrooms – 2 Bathrooms | Wood | 37500 Euros | 431 Euros/m2c |
| House 4 | 269 m2 Built | 3 Bedrooms – 3 Bathrooms | Wood | 94300 Euros | 350 Euros/m2c |
| House 5 | 36 m2 Built | 1 Bedrooms – 1 Bathrooms | Metallic | 27500 Euros | 764 Euros/m2c |
| House 6 | 100 m2 Built | 3 Bedrooms – 1 Bathrooms | Metallic | 87500 Euros | 875 Euros/m2c |
| Housing 7 | 300 m2 Built | 5 Bedrooms – 3 Bathrooms | Metal – Concrete | 320500 Euros | 1070 Euros/m2c |

| House 8 | 82 m2 Built | 2 Bedrooms – 2 Bathrooms | Concrete | 140000 Euros | 1700 Euros/m2c |
| Housing 9 | 203 m2 Built | 4 Bedrooms – 3 Bathrooms | Concrete | 332000 Euros | 1600 Euros/m2c |
Things you should know about the price:
In our case, we asked a colleague who is dedicated to building manufactured homes we were told approximate price per square meter of a house finished with everything included; with normal standards They are around 1400 and 1500 € per square meter built .
From here, then to ask in several companies and Always ask for a detailed budget for the construction of the prefabricated housing so you can compare. By the way! Also ask for references of real houses already built.
It should be noted that the types of houses prefabricated that we can find in the market have had an exhaustive study on its behavior energy and bioclimatic . An advantage that It allows significant savings in energy expenditure. In base to the "container" standard we can identify its behavior in the following image:
A lot of efficiency and more, but... are they really comfortable? Well As an example I add the following video that I think is They explain very well the essence of housing in a house pre-made, as well as being a real case:
In this sense, bioclimatism in the design is recommended see:
In this case we have to go to Australia to the company Archiblox committed to sculpting ecological houses modular that generate more energy than they consume, awarded with different prizes.
In Spain, there is hardly any a housing industry prefabricated ecological, what's more, the people usually have a very vague general idea of this « modern architecture« , associating it rather with temporary and low-quality constructions. With this panorama, It is very meritorious that a Spanish NOEM company focused on a business of sustainable prefabricated houses with zero carbon footprint, obtain the European Award for Entrepreneurial Spirit.
Shapes, new technology and different layout compositions in modular homes are made up of a modular aesthetic of great value and in some cases, even risky in its design . The prefabricated modern house is here and this is an example of forceful innovation. The House invisible…
This wonderful home is built by DMAA. Must to remember that architectural modulation also penetrates in all types of construction; from buildings, ships industrial or coworking offices to give some examples more.
In this section, what we want is to port manuals or PDF guides on how to build a prefab house step by step step and have a perspective and intuit the works, plans, measurements and needs, tools, materials, concrete, wood… etc.
The documentation represents the steps that we are going to need in the construction of housing modules as well as generic reports of the needs and objectives of the modular architecture.
Keep in mind that the more parts of the passenger compartment are executed in the factory, in a house of modules , we will have a higher quality in the design both outside - inside and in the facilities of air conditioning, doors, walls, finishes and qualities of materials, in the joints that form the envelope…etc.
The following video represents a completed building almost factory. An example of building housing in 4 days:
Now it's time for a completed on the ground, taking into account that the level of prefab can vary, from chunks of walls to complete parameters and in the same way on the ground or deck. An example of building a house in 7 days:
The manuals and guides that we recommend are:
A problem that exists in terms of information existing and the resources in the network is that the construction prefabricated undoubtedly derives from wood.
In this sense, from the article Architecture with wood, more than 50 practical manuals and reports that extend the information to the full in this sense, although, as a complement, we provide some documents that seem of interest to us.
