Spain has a broad range of modular home manufacturers. Buyers can find permanent concrete houses, steel-frame modular homes, compact transportable units and large modular systems intended for housing developments.
A modular home is produced partly or mainly in a factory before being transported to the building site. In volumetric construction, complete three-dimensional sections arrive as rooms or parts of rooms. Other industrialised systems use factory-made walls, floors or structural frames that are assembled on the plot.
These differences matter. A compact module designed for tourism is not directly comparable with a permanent concrete family home or a multi-storey modular housing system.
This guide introduces ten notable Spanish manufacturers and explains the type of buyer or project each company is most likely to suit.
How the manufacturers were selected
This is an editorial shortlist rather than a ranking based on sales, turnover or production capacity.
The manufacturers were selected from PrefabFind’s wider Spanish market database because they have an identifiable modular or industrialised residential offer, an official company website and enough published information to understand their construction system and target buyer.
The list includes manufacturers serving private buyers, tourism operators, property developers and institutional clients. Some companies produce complete volumetric modules, while others use factory-made concrete walls or structural systems.
Buyers should therefore compare the actual construction method and delivery scope rather than relying only on the term “modular home”.
10 top modular home manufacturers in Spain
1. Modular Home
Modular Home is a Spanish manufacturer of permanent concrete modular homes. The company operates through Modular Home Systems and has been active since 2013.
Its MH construction system is used for detached houses as well as business, hospitality and additional-space modules. Buyers can begin with one of the company’s catalogue models or request changes to the floor plan, exterior appearance and interior specification.
The company also develops smaller mobile-format modules for glamping, commercial spaces and additional living accommodation. Its project services cover Spain and Portugal.
Modular Home is a relevant starting point for buyers seeking a permanent concrete residence and for business clients planning repeatable accommodation units.
2. AK Modular
AK Modular designs and manufactures permanent modular residences using an industrialised steel-based construction system.
The company offers two main routes. Buyers can commission an individual house designed around their plot and requirements, or consider the more standardised Express range where a model-based process is suitable.
AK Modular was established in 2006 and has production operations in Vitoria-Gasteiz and Coria. Its offer is aimed mainly at buyers seeking a permanent residence rather than a caravan or lightweight mobile home.
The combination of custom projects and repeatable models makes AK Modular relevant to both individual homeowners and buyers considering several similar units.
3. MasArea Modular
MasArea Modular manufactures permanent houses in a controlled production facility in Illescas, Toledo.
Its construction method combines a steel structural system with concrete elements, insulation and factory-prepared finishes. Buyers can use a catalogue design as the starting point or develop an individual house with a different layout, façade and interior package.
The company also accepts independently developed architectural projects. Delivery scope can vary from the main building structure to a more extensively finished home.
MasArea Modular was established in 2022. It is particularly relevant to buyers in central Spain who want a factory-produced house but still require substantial design flexibility.
4. Modularium
Modularium supplies energy-efficient modular houses based on a galvanised-steel building system developed with Modiko technology.
Its plans are organised into several geometric house families. The internal arrangement, number of rooms, orientation, exterior appearance and finishing materials can be adjusted according to the project.
The technical package focuses on insulation, airtightness, controlled ventilation and the option to add renewable-energy systems. The exact performance and certification level depend on the final specification selected by the buyer.
Modularium is worth comparing when a buyer wants a permanent steel modular home with a defined technical envelope but does not want to be restricted to one fixed layout.
5. KEU
KEU produces compact, transportable modular residences in Spain. The company operates under Diseño Formas y Líneas and was founded in 2019.
Its homes use engineered steel structures and are delivered with integrated interiors. Depending on the model and specification, this can include a kitchen, bathroom, building systems and fitted finishes.
The company’s documented range extends from compact 23-square-metre units to villas of approximately 77 square metres. KEU targets private leisure use, hospitality developments, premium rental accommodation and international projects.
KEU is most relevant for buyers looking for a highly finished small home that can be transported as a factory-completed unit. The buyer still needs to arrange suitable land, access, utility connections and local project approvals.
6. The Concrete Home
The Concrete Home develops detached houses using factory-produced concrete wall systems.
This is industrialised concrete construction rather than a conventional transportable room-module system. The main structural components are manufactured away from the plot and then assembled as part of the permanent house.
Buyers can select a model-based plan or commission a customised home adapted to the land and architectural brief. The company provides project management and offers different delivery scopes, from construction-focused packages to more complete project formats.
The Concrete Home was founded in 2015 and works from Madrid, with regional activity that also includes Andalusia. It is relevant to buyers seeking the solidity of a concrete house combined with a more controlled production process.
7. CompactHabit
CompactHabit manufactures three-dimensional reinforced-concrete modules for permanent buildings.
Its system is primarily aimed at larger projects, including apartment housing, hotels, student residences, healthcare buildings and educational facilities. Modules can leave the factory with a substantial part of the installations and interior work already completed.
The company was established in 2004 and operates from Cardona, near Barcelona.
CompactHabit is not mainly positioned as a catalogue-home seller for an individual buyer. It is more relevant to developers, public organisations and professional project teams planning multi-unit housing or buildings with repeated rooms.
8. Arquitectura Modular
Arquitectura Modular designs and constructs modular buildings for residential and commercial use.
The company’s work includes detached houses, offices, sales buildings and other customised spaces. Its construction approach uses structural modules that can be combined and finished around the project rather than offered only as fixed standard cabins.
Arquitectura Modular was founded in 2004 and operates from Librilla in Murcia. Its documented experience includes projects in Spain and international markets.
The company may suit a private buyer seeking a configurable steel-based home, but it is also relevant to businesses that need offices, customer spaces or other modular premises.
9. Cimpra
Cimpra develops industrialised buildings around modular steel structures.
Its system can be applied to private homes, offices, educational buildings and other commercial or institutional spaces. Projects are developed around the client’s required layout and use rather than being limited to a large catalogue of standard house models.
Factory preparation reduces the amount of structural work that must be completed on the final site. The company operates from Utrera in the province of Seville.
Cimpra is relevant to buyers who want a customised steel-frame modular house and to developers planning buildings that may need repeated structural sections.
10. Home Center
Home Center supplies several types of factory-produced accommodation, including permanent modular houses, compact mini homes and mobile units.
The company operates from the Barcelona area and has display locations in Catalonia. Buyers can compare fixed residential construction with more transportable forms of accommodation through one supplier.
Home Center offers different delivery levels, including structural packages and more extensively completed specifications. The appropriate option depends on whether the building will serve as a permanent residence, leisure property or relocatable unit.
This company is most relevant to buyers who have not yet decided between a fixed modular home and a mobile or compact alternative.
Which Spanish modular manufacturer may fit your project?
For a permanent concrete family home, begin by comparing Modular Home, MasArea Modular and The Concrete Home.
Modular Home and MasArea both provide model-based and customised routes. The Concrete Home uses factory-produced concrete walls rather than complete volumetric rooms, so buyers should compare how much work is completed in the factory and how much is carried out on the plot.
For a steel-based permanent residence, AK Modular, Modularium, Arquitectura Modular and Cimpra are the most relevant companies in this shortlist.
AK Modular combines individual designs with a standardised range. Modularium places greater emphasis on the technical building envelope and energy systems. Arquitectura Modular and Cimpra also work across commercial and institutional building types.
For a compact home, second residence or tourism project, KEU and Home Center provide the most directly relevant offers.
KEU concentrates on completed transportable residences with integrated interiors. Home Center covers a broader selection, including permanent modules, mini homes and mobile units.
For apartment buildings, student residences, hotels or other multi-unit developments, CompactHabit is the clearest specialist in this list. Its reinforced-concrete volumetric system is designed mainly for professional developments rather than individual catalogue-home orders.
What to check before choosing a manufacturer
Begin by confirming exactly what the company means by “modular”.
Ask whether the house will arrive as complete three-dimensional modules, structural wall panels, a steel frame, concrete wall sections or a combination of different systems.
Send every manufacturer the same project brief. Include:
The location of the plot.
Intended use of the building.
Required floor area.
Number of bedrooms and bathrooms.
Preferred number of floors.
Target level of interior completion.
Site access information.
Intended project schedule.
Ask for a written breakdown of what is and is not included in the quotation. Important items include design work, technical studies, foundations, transport, crane installation, utility connections, kitchens, bathrooms, heating, ventilation and exterior works.
Do not compare a structural package with a fully completed house as though they were the same product.
A manufacturer may describe a project as turnkey while still excluding the land, foundations, professional fees, municipal charges, utility connections or landscaping. The contract and technical specification should define every responsibility clearly.
Buyers should also investigate transport access before finalising the house design. Large factory-built sections may require wide roads, suitable turning space and enough room for a crane.
Planning and construction requirements can vary by municipality, autonomous community, plot and building type. A local architect or relevant municipal office should confirm what documentation applies to the specific project.
Conclusion
Spain offers modular home manufacturers for several different buyer groups.
Modular Home, MasArea Modular and The Concrete Home focus on permanent concrete housing. AK Modular, Modularium, Arquitectura Modular and Cimpra provide steel-based industrialised systems. KEU and Home Center cover smaller or more transportable buildings, while CompactHabit serves larger residential and institutional developments.
The best manufacturer is not necessarily the company with the largest catalogue. Buyers should compare the construction system, factory completion level, delivery area, design flexibility and work that remains to be completed on the plot.
