Engineered in ISO 9001/14001 certified manufacturing plants, our modular building solutions are optimized for rapid deployment, CTE (Código Técnico de la Edificación) structural standards, and severe coastal or inland microclimates across Spain.
The Spanish residential construction market is undergoing a paradigm shift toward offsite industrialized housing. To successfully procure single-story modular homes in Spain, OEM/ODM manufacturers must comply strictly with Spain’s rigorous building framework: the Código Técnico de la Edificación (CTE).
Spain spans diverse climate zones—from Atlantic Northern regions (Zone C1) to the high-plateau winters of Madrid (Zone D3/E1) and intense Mediterranean summer heat (Zone A4/B4). Our single-story modular homes incorporate customized continuous thermal envelopes featuring PIR core sandwich panels, continuous exterior insulation (SATE systems), and argon-filled double/triple glazing to guarantee an Energy Class A rating.
Designed engineered according to Spanish seismic standards (NCSE-02) and wind loads (DB-SE-AE). Our cold-formed light gauge steel (LGS) and structural module frames utilize high-yield galvanized steel (S350GD + Z275 / G90). Structures withstand coastal winds up to 160 km/h along the Costa Brava and Andalusian coastlines without structural deflection.
With thousands of kilometers of coastline across Valencia, Murcia, Andalusia, and the Balearic/Canary Islands, coastal salt fog is a major failure point for standard prefabricated steel. We apply automotive-grade electro-coated primers, hot-dip galvanization, and fluorocarbon topcoats ensuring 30+ year corrosion resistance under harsh maritime conditions.
As a direct-to-developer factory supplier, we offer end-to-end customization to adapt structural blueprints to local urban planning requirements (PGOU - Plan General de Ordenación Urbana).

From single-family residential projects to fast-turnaround hospitality real estate, offsite single-story modular buildings fit key market demands across autonomous communities.
In high-demand resort areas such as Marbella, Estepona, and Sotogrande, land values require short construction schedules to maximize Return on Investment (ROI). Single-story modular luxury villas can be prefabricated offsite in 30 days and installed in less than a week, avoiding noisy long-term construction nuisance in luxury urbanizations while satisfying high solar gain resistance standards.
The Levantine coast faces stringent eco-protection laws near coastal waters. Expandable container houses and low-impact single-story modular homes provide minimal ground disturbance, avoiding deep wet foundations. They offer turn-key hotel accommodations featuring designer composite wood facades that blend into Mediterranean pine forests.
Suburban municipalities surrounding Madrid (such as Las Rozas, Majadahonda, and Toledo border regions) suffer from soaring traditional construction labor costs. Our factory-built single-story homes offer fixed-cost predictability, insulated against Madrid's harsh winter freezing temperatures and extreme summer heat waves.
Transporting wet cement and skilled tradespeople to Mallorca, Ibiza, or Tenerife carries massive premiums. Our flat-pack and modular container home packages load seamlessly into standard 40ft High Cube sea shipping containers delivered direct to ports in Palma or Las Palmas, dramatically slashing island construction logistics overhead.
Navigating legal requirements in Spain is essential for a seamless installation. Modular homes anchored to foundations are legally classified as real estate (Bienes Inmuebles) and require standard municipal approvals.
To apply for a major building permit (Licencia de Obra Mayor), a certified Spanish collegiate architect must sign off on the technical plans. Prefabex supplies complete BIM/CAD files, structural calculations, and material specification sheets to simplify architect approval.
Homes can be legally installed on designated urban land (Suelo Urbano). On rustic land (Suelo No Urbanizable / Rústico), regional regulations vary; removable mobile tiny homes without fixed concrete foundations may be permitted under specific agricultural or eco-tourism exemptions.
Once utility connections (water, electricity, sanitation) and foundation footings are inspected, the municipality issues the Certificate of Occupancy (Cédula de Habitabilidad / Licencia de Primera Ocupación), enabling mortgage financing and legal residential use.
Offsite modular manufacturing eliminates weather delays, reduces site labor requirements by up to 70%, and provides strict fixed-price guarantees against material price inflation in Spain.

We serve as a integrated OEM/ODM manufacturing hub, combining architectural engineering with global maritime logistics direct to Spanish container ports.
Our manufacturing complex strategically accesses deep-water shipping lanes, providing direct container transport to key Spanish ports including Valencia, Barcelona, Algeciras, Bilbao, and Santa Cruz de Tenerife with full customs documentation clearance support.
We supply Spanish modular home retailers, developers, and architectural firms on a white-label basis. Customize floor plans, branding, external cladding finishes, interior trim packages, and electrical socket standards (EU Type F Europlug) direct at our factory.
Every single-story modular housing module undergoes multi-stage quality control. Steel framing, structural welding, structural sandwich panel adhesion, and plumbing pressure tests are certified under EN 1090-1 structural steel manufacturing norms.
