Prefabricated Houses: Prices, Advantages, and Key Insights for Investors and Owners in 2025

The prefabricated house market is booming in 2025, driven by growing demand for fast, efficient, and sustainable solutions as well as advances in materials and technology applied to the sector. For real estate professionals, investors, architects, and homeowners, understanding the price landscape, key advantages, and challenges of this sector is as relevant as identifying competitive opportunities in a context of strong innovation.

What Are Prefabricated Houses and Why Are They Booming in 2025?

Prefabricated houses are dwellings whose main construction is carried out off-site, in a factory, and later assembled at the destination. The 2025 boom is linked to three factors: housing access crisis, the search for greater energy efficiency, and creative freedom to customize spaces and styles.

Compared to traditional construction, the industrialized process of prefabricated houses minimizes errors and reduces time and costs. In addition, modular architecture facilitates future modifications or expansions.

Prices of Prefabricated Houses in Spain: What Do They Depend On?

The price of a prefabricated house in 2025 mainly depends on materials, surface area, design, and equipment. According to RealAdvisor, there are small and functional options starting at €50,000 (for basic wood or compact modular models), although the mid-range segment, around 80-120 m², ranges between €80,000 and €140,000, depending on typology and finishes. Premium concrete houses, with modern finishes and high efficiency, can easily exceed €180,000.

The Spanish market especially stands out in concrete houses, which combine durability, reduced maintenance, and thermal advantages. According to data from The Concrete Home, the cost of a prefabricated concrete house is 10-20% lower than that of a traditional construction of the same size and quality, excluding the price of the land (source).

Factors Influencing the Final Cost of a Prefabricated House

• Materials: wood, concrete, steel, mixed modular. Concrete stands out for its durability and thermal efficiency.
• Surface and layout: from microhomes to large family houses, size linearly multiplies the cost.
• Level of customization: standard models are more economical, while customization implies a price increase.
• Location of the plot and accessibility: transportation and assembly can represent up to an additional 8-10%.
• Interior equipment and finishes: installations, exterior carpentry, and kitchens notably influence.

Professional support, permits, and project drafting should also be added to the overall budget, similar to a conventional home. Access to financing follows requirements similar to traditional construction (source).

Differential Advantages of Prefabricated Houses Compared to Traditional Construction

• Speed of execution: 4-6 months on average compared to 12-18 months for traditional construction.
• Fixed budget and lower risk of cost overruns due to unforeseen events.
• Energy efficiency and less material waste.
• Customization capacity tailored to trends and family or investment needs.
• Property appreciation linked to energy efficiency and flexibility.

What Should You Analyze Before Investing or Marketing Prefabricated Houses?

• Legal and urban planning requirements of the plot.
• Taxes and transfer: similar to new build housing (VAT, municipal fees, etc.).
• Projects approved by certified technicians or architects.
• After-sales services and guarantees: essential for appreciation in the secondary market.
• Capacity for staging and digital visual tools to more efficiently attract buyers.

In an increasingly competitive market, the use of digital solutions for visualization and customization is a differentiator. Virtual staging and advanced editing tools like Fill Room, Redesign or Lemma from Deptho allow showing different layouts, styles, and finishes to potential buyers without the need for physical construction.

Thinking of Investing? Opportunities and Challenges for 2025

Interest in prefabricated houses translates into higher demand for second homes, vacation rental investors, and first-time buyers. The payback time in rental-oriented projects is shorter (due to faster delivery and total cost savings). After the pandemic, the desire for outdoor spaces and improved quality perception have driven the sector's expansion.

However, the challenge is the lack of culture around this type of housing and the scarcity of urban plots available at reasonable prices. Training real estate agents and designers on the specifics of the product is essential to position each project distinctively.
