Manufacturers of precast concrete houses

Updated on 24 September 2026 · Data from public sources, each with its link · How we work

Concrete houses to live in all year round: solid, good at keeping out noise, able to hold on to warmth and coolness, and needing hardly any upkeep. But “prefabricated” does not mean the same thing for all of them: some arrive as almost finished modules, others are assembled on your plot from walls made in a workshop, and a few only bring the floor slabs from the factory; here you can see how each brand builds and what its price covers.

If you are looking for specific houses rather than brands, you will find them one by one in prefab concrete houses.

1.Atlántida Homes: steel modules with concrete floor slabs, and the paperwork in the price

Its concrete is in the floor slabs and in the façade panels; the structure of each module is steel, and the modules leave the factory finished and are joined on the plot in one day. According to its website, its fixed price includes the ground surveys, the design project, site supervision, the permit and a simple foundation, but on a sloping plot or on soft ground the foundation is quoted again. It suits you if you want the house finished without having to coordinate anyone.

Since 2015Delivers to mainland Spain

In favour

It allows a basement or semi-basement under the house

Worth bearing in mind

Its lead time only counts the building work (four months): the surveys, the design project and the permit come first and depend on the town hall
It does not say whether it charges more to take the house far from Madrid

2.The Concrete Home: load-bearing reinforced concrete walls made in a workshop

It builds the house with load-bearing reinforced concrete walls that it makes in its workshop and, according to the brand, lifts onto the slab with a crane in two or three weeks; the floors are hollow-core slabs and the rest of the work is done on the plot. Per square metre, its median is 2,025 €/m², close to that of turnkey concrete houses (2,025 €/m²), and that with a price that already includes the foundation, the earthworks, transport and an air source heat pump with underfloor heating. It only quotes for projects in Madrid, Catalonia and Andalusia.

Delivers to 13 provinces

In favour

Its website gives you the price of each house instantly, by square metre and by region, without asking for a quote
It commits in writing to an A energy rating for all its houses

Worth bearing in mind

The design project, the permit and the professional fees are not in its starting price: it charges them in its other option, “all inclusive”
No house in its catalogue has been built exactly as shown: what it has built are custom projects, almost all in Madrid and its sierra

3.inHAUS: concrete villas that leave the factory almost complete

Almost all the work is done in its workshop: each module is a steel frame with concrete floors, walls and ceilings, and according to the brand it leaves the factory nearly finished, so all that is left on your plot is to lift it into place with a crane in one day and finish it off. It builds large villas as main homes, with the design project, transport, assembly and permits in the price, but the foundation, with its geotechnical and topographic surveys, is not included. It suits you if you want a lot of house and little building work on your land; if you are after a small house, it does not have one.

Delivers throughout Spain

In favour

It has delivered work behind its system (more than one hundred and sixty houses, according to the brand)

Worth bearing in mind

Its specification of finishes can only be seen after registering on its website, so its insulation and its heating and cooling cannot be compared from outside
It shows the houses in its catalogue as computer renderings, not as photos of finished builds

4.QCasa: concrete only, made in its own plant and assembled on your plot

It works only with concrete, which it makes in its own plant: it takes the pieces to the plot and assembles them on a foundation built there. Its signature is the flat-roofed detached house with a Mediterranean look, on one or two floors, which it adapts in size and layout, although it also builds pitched roofs. It is for people building in its area who want a traditional concrete house made with factory methods; it does not publish its insulation, energy rating or lead time, so ask for them in writing before comparing.

30 years of experienceDelivers to 11 provinces

In favour

It has compact houses (from 83.16 m²)
There are single-storey models with four bedrooms, for those who do not want stairs

Worth bearing in mind

Its website and its floor plans do not always count the same bedrooms: ask for the plan of your model
Its map lists more provinces than its quote form then lets you choose

5.Construcciones ALC: a site-built house with a precast floor slab, at a fixed price

It advertises its homes as precast concrete houses, but the load-bearing walls are clay block and are built on your plot: what is prefabricated are the hollow-core floor slabs, and the concrete is also in the foundation slab and in the ring beam that ties the walls together. It is traditional construction at a fixed price, and according to its website that price includes the geotechnical survey, the design project, the fees and the professional approval, the handling of permits, the foundation and the installations. It suits you if you want a site-built house with the budget closed from the start; not if you are looking for a factory-made house.

Delivers throughout Spain

In favour

If none of its models suits you, it designs one for your plot at no extra charge, according to its website
The only things it names outside the price are distant utility connections and a few optional finishes

Worth bearing in mind

Its specification of finishes is several years old, and the window frames change from one page to another: ask for the current one before signing
Heat recovery ventilation, on which it bases its promise of savings, is optional
It only shows its houses as computer renderings, with no photos of finished builds

6.Resan Modular: steel modules with concrete floor slabs and the permit in the price

Its concrete is in the floor slabs: the structure of the modules is steel and the façade is cement board. The house leaves the workshop in modules that are joined on the plot, and if the access will not let one through, it builds the house on site instead. According to its website, its quote includes the design project, the building permit and the first occupancy licence, earthworks, transport and assembly, but the foundation, the kitchen units and the utility connections are extra. It suits a mid-sized house with the paperwork taken care of.

Over 25 years in construction

In favour

It has an assembled house you can visit before deciding (its smallest model)

Worth bearing in mind

Check that its range is still on sale: the website for its models has not been touched for years and its group's website does not show them
Its standard heating is basic for the A rating it advertises (electric convectors or a gas boiler)

Our verdict

If you want to see the price before you call, The Concrete Home (in Spanish) calculates it on its website by square metre and by region, with the foundation included, and assembles load-bearing concrete walls made in its own workshop on your plot. QCasa (in Spanish) does the same with pieces from its own plant, but on a quote basis and only in the provinces of its area. If you want as little building work as possible on your land, inHAUS (in Spanish) brings almost finished concrete and steel modules for large villas, and Atlántida Homes (in Spanish) and Resan Modular (in Spanish) bring steel modules with a concrete floor slab, with the design project and the permit in the price.

Construcciones ALC (in Spanish) is for those who prefer a site-built house, with clay block walls and a precast floor slab, at a fixed price. All the houses in this material, one by one, are in prefab concrete houses.

Frequently asked questions

What are the advantages of a concrete house over a timber one?

It insulates better against noise, resists fire, needs very little maintenance and, because of its mass, is slow to heat up and to cool down, so it smooths out temperature swings inside the house. Timber is lighter and makes do with a lighter foundation. And concrete costs more: among turnkey houses, its median is 2,025 €/m² (40 houses from 7 manufacturers), compared with 1,267 €/m² for timber (47 houses from 10 manufacturers). Nor is there a kit shortcut: in concrete you will not find kits to assemble yourself.

Are all precast concrete houses built the same way?

No, and it changes how much work happens on your plot. inHAUS (in Spanish) (in Spanish) brings almost finished modules with concrete floors, walls and ceilings; Atlántida Homes (in Spanish) (in Spanish) and Resan Modular (in Spanish) (in Spanish), steel modules with a concrete floor slab. The Concrete Home (in Spanish) (in Spanish) and QCasa (in Spanish) (in Spanish) make the concrete pieces in a workshop and assemble them on the plot, where the rest is done. And Construcciones ALC (in Spanish) (in Spanish) builds the walls on site in clay block and only prefabricates the floor slab. The more that arrives made in the factory, the less the work depends on the weather and on local trades, but the more it matters that a large lorry and a crane can reach your plot.

What is usually left out of the price of a concrete house?

The plot always and, for the brands that publish a price, VAT too. The rest varies a lot: The Concrete Home (in Spanish) (in Spanish) and Construcciones ALC (in Spanish) (in Spanish) include the foundation in the price, and so does Atlántida Homes (in Spanish) (in Spanish) if the plot is flat, while inHAUS (in Spanish) (in Spanish) and Resan Modular (in Spanish) (in Spanish) leave it out, along with the ground surveys. Utility connections beyond a few metres are paid by the buyer with all those that spell it out. Before comparing two quotes, ask each one for the list of what is included.

How long does it take to get a precast concrete house?

Each brand counts the lead time from a different moment, and that matters more than the number. According to them, inHAUS (in Spanish) (in Spanish) delivers between six and nine months after the design is closed; The Concrete Home (in Spanish) (in Spanish) gives six to eight months of building work; Atlántida Homes (in Spanish) (in Spanish), four months of building work; Construcciones ALC (in Spanish) (in Spanish), five at most from the start of work, and Resan Modular (in Spanish) (in Spanish), about three from when the permit is granted. QCasa (in Spanish) (in Spanish) does not publish a lead time. In almost all of them the permit comes first and depends on the town hall: ask when the clock starts.
