The Definitive Guide to Modular Homes
Myths vs. Reality
Discover the truth about industrialized modular architecture and how it is revolutionizing the concept of home construction.
What is an Industrialized Modular Home?
Real Definition
An industrialized modular home is a permanent buildingDesigned by architects, built in a controlled factory environment with industrialized processes, divided into self-supporting three-dimensional modules, which are transported fully finished and assembled on the site in a matter of hours or days.
It's not a caravan, it's not a container home, it's not temporary, and it's not a low-quality solution. It's a newly built home that complies with all current urban planning, technical, and habitability regulations in Spain.
What MOODUL offers
MOODUL is a company specializing in the construction of industrialized single-family homes with a comprehensive approach: from architectural design to turnkey delivery.
Their system is based on three-dimensional modules of metal and concrete structure manufactured entirely in-house, which guarantees greater control in terms of deadlines, costs and quality compared to traditional construction.
How is it different from a prefabricated house?
| Aspect | Basic Prefabricated House | Modular House MOODUL |
|---|---|---|
| Structure | Lightweight, panels or basic systems | Rigid three-dimensional steel/concrete structure (M-STAK) |
| Personalization | Limited or non-existent | High degree of architectural customization |
| Manufacturing | By pieces or panels | Complete 3D modules with included installations |
| Regulations | It does not always comply with CTE | It meets or exceeds all regulations (CTE, etc.) |
| Location | Sometimes limited to campsites or specific areas | Urban plots with regular building permit |
| Durability | Variable, sometimes limited | Equivalent to or better than traditional housing |
| Financing | Difficult or impossible to mortgage | Fully mortgageable as a conventional home |
Myths vs. Reality about Modular Homes
MYTH: Modular homes are of low quality
+REALITY:
Factory production allows for a level of control that is impossible to replicate on-site. At MOODUL:
- The finishing work is carried out under optimal conditions, without humidity, dust, or haste.
- Insulation, adhesives, paints, and sealants are applied in a homogeneous and controlled manner.
- All installations are checked and tested before transport
- The finishes are mid-to-high range and high-end depending on the type.
- Quality control is systematic and documented module by module
The result is homes that are more airtight, efficient, quiet, durable, and healthy than many traditional homes.
MYTH: All modular homes are the same
+REALITY:
MOODUL works with registered architects who design each project individually. Industrialization does not mean uniformity:
- Each home is designed according to the client's needs and the characteristics of the land.
- The modules allow for endless architectural combinations
- Everything can be customized: layout, finishes, materials, carpentry, installations
- Customization does not affect the efficiency of the manufacturing process
- No two MOODUL houses are exactly alike.
MYTH: Modular homes cannot be mortgaged
+REALITY:
MOODUL modular homes are fully mortgageable because:
- They require a municipal building permit, just like any traditional house.
- They are built on permanent foundations on the client's plot
- They have a basic and execution project signed by architects
- Upon completion, a final work certificate and occupancy permit are issued.
- They comply with all current technical and urban planning regulations.
- Banks value them the same as conventional homes (or better because of their energy efficiency)
In fact, many entities value industrialization positively because it reduces the risk of delays and cost overruns.
MYTH: Modular construction is a "low-cost" solution
+REALITY:
MOODUL is not "low-cost", it's "high-value". The difference is fundamental:
- The price per m² is competitive with traditional construction of equivalent quality.
- The efficiency of the industrial process is invested in higher quality and performance
- It includes mid-to-high-end finishes, efficient installations, and integrated home automation.
- The added value lies in the predictability of deadlines, costs and quality
- In the long term, energy and maintenance savings offset the initial investment.
MYTH: Modular homes don't last as long as traditional ones
+REALITY:
The durability of a MOODUL modular home is equivalent to or greater than that of a traditional construction:
- The M-STAK structure is made of galvanized steel and high-strength concrete
- All materials are certified and from top brands
- Factory execution control guarantees higher quality in joints and seals
- The property complies with all the guarantees of the LOE (10 years structural, 3 years installations, 1 year finishes)
- In countries with a longer tradition, there are modular homes that are over 50 years old and in perfect condition.
MYTH: They do not adapt to complex terrains
+REALITY:
MOODUL modules adapt to virtually any terrain:
- The foundation is designed specifically for each plot according to a geotechnical study.
- Slab foundations, isolated footings, or piles can be used as needed.
- On sloping terrain, they are adapted using terraces or pillars of different heights.
- The relative lightness of the modules reduces foundation requirements compared to traditional construction.
- MOODUL houses have been built on land with slopes of more than 4 meters
MYTH: Energy efficiency is lower
+REALITY:
MOODUL homes achieve an energy rating of A or higher as standard:
- Continuous factory insulation eliminates thermal bridges
- High-performance windows with triple glazing minimize losses
- The mechanical ventilation system with heat recovery recovers the 90% energy
- Aerothermal energy combined with radiant floor heating/cooling optimizes consumption
- Factory-controlled watertightness far surpasses that of traditional construction.
- Customers report energy bills 60-70% lower than conventional homes
M-STAK Construction System
The M-STAK system is the technological heart of MOODUL. It is a self-supporting, three-dimensional structure that combines the advantages of galvanized steel with the thermal mass of concrete.
Technical specifications
- Structure made of high-strength galvanized steel profiles
- Composite slab with reinforced concrete slab
- Multi-layer enclosures with continuous high-density insulation
- Complete integration of facilities within the module itself
- Factory-applied interior and exterior finishes
- Maximum dimensions per module: 4.5m x 12m x 3m (height)
Advantages of the system
- Maximum structural strength and durability
- Superior seismic performance compared to traditional construction
- High-efficiency thermal and acoustic insulation
- Total architectural flexibility
- Fast on-site assembly (hours, not months)
- Minimal environmental impact during installation
Why M-STAK?
Unlike lightweight timber or panel systems, M-STAK offers the robustness of a heavy-duty structure with the advantages of industrialization. This results in homes with improved acoustic performance, greater durability, better fire resistance, and a sense of solidity comparable to traditional construction.
