Services and Areas

What services do you offer?

Three options using the same system: kit without assembly (we send you all the materials cut to size and the plans), kit with assembly (our team assembles the structure, the facade, and the roof), and turnkey (we handle the entire construction project). Learn more about the kit and turnkey options.

Which areas do you cover?

We ship the unassembled kit worldwide. The assembled kit is delivered to job sites located no more than 2 hours and 30 minutes from Lleida. The turnkey solution is available in the provinces of Lleida and Tarragona.

Do you supply doors and windows?

No. We supply the frame, the siding, the roof, the flashing, and the screws. Doors and windows are ordered separately; as an option, we can include wooden window frames.

Deadlines and Price

How long does it take to build a prefabricated house?

The structure is assembled in one week, and the insulation panels are installed in another. Including the foundation, utilities, and finishing touches, the house is usually completed in 3–4 months.

Is it cheaper than a traditional house?

The savings come mainly from the timeline: about 75% of the materials are the same as those used in traditional construction, but labor costs are significantly reduced. The price depends on the square meters, the number of floors, and the finishes; we’ll provide you with a quote based on your blueprints.

How much does a StarModul prefabricated house cost?

Each home is custom-priced: the cost depends on the floor area, the number of stories, the roof, the finishes, and the delivery option (kit, kit with assembly, or turnkey). We’ll provide you with a no-obligation quote based on your plans. We’ll explain what factors influence the price of a prefabricated home.

How do I request a quote?

Send us the blueprints or your vision for the house, the approximate square meters, and the location of the lot using the contact form, by phone, or via WhatsApp.

Project, License, and Funding

Do I need a project plan and a license?

Yes, just like any other home. Your architect draws up the plans and applies for the building permit; the structural calculations are signed off by an engineer (we can provide a quote for this). With our turnkey service, we take care of everything. We’ll explain the process step by step in our guide to obtaining a building permit for a prefabricated home.

Can you build on rural land?

It depends on regional and municipal regulations and on the specific lot: a prefabricated house is treated the same under the law as a traditional one. We explain this in our article on prefabricated houses on rural land.

Can you take out a mortgage on a prefabricated house?

Yes, it is financed just like a new-construction home. For more information, see the mortgage requirements.

Construction and Materials

What is the StarModul system?

A patented set of bolted connectors for galvanized steel structures. It allows for the assembly of lightweight, demountable structures without welding, both in homes and other buildings. Learn more about the system.

What kinds of structures can be built?

Single-story or two-story homes, additions, porches, and storage sheds. Because it is lightweight, it can also be used for additions to existing buildings.

Does the design impose any limitations?

No. With more than 100 joint references, any shape or layout can be achieved, without the limitations of closed modular systems.

What finishes are available?

On the exterior, exposed paneling in various colors, SATE, porcelain tile, a ventilated facade, or other cladding materials. On the interior, drywall is standard, although wood paneling or other finishes can be used.

What kind of foundation do you need?

Since the house is lightweight, the foundation is designed to handle low loads. It is typically a concrete slab, footings, or a crawl space, depending on the geotechnical study and structural calculations. You’ll find the solutions in the construction details.

Does a steel house rust?

No. We use galvanized steel: the zinc protects the steel from corrosion. The outer sandwich panel is watertight, and the home is covered by the statutory building guarantees (in Spain, those of the LOE: 1 year for finishes, 3 years for habitability and 10 years for the structure).

Is it affected by moisture, pests, or mold?

No. Neither the galvanized steel nor the panel's insulating core absorbs water, and they are resistant to fungi, mold, and other biological agents.

How does it behave when exposed to fire?

The panels have a fire reaction classification of B-s2,d0. The structure is protected in accordance with the Technical Building Code using specific gypsum board linings (R30 in residential units and R90 in garages).

Can it be expanded later?

Yes. Since it is bolted together, the structure can be modified or expanded. All that's needed is a new structural analysis.

Do you have any other questions?

A technician will get back to you. Tell us about your project, and we'll help you choose the best option.
