UNIMODUL is OBRALIA's modular steel system for homes and accommodation: modules are built and fitted out in a workshop under quality control and assembled on the plot, which shortens on-site work and reduces schedule uncertainty.

It is an alternative to 3D printing, not an internal competitor: the choice depends on the brief, the site and the client's priority (formal freedom versus speed and repeatability). In both cases the project complies with the CTE and is contracted at a fixed price.

• Industrialised steel structure and envelope.
• Suited to accommodation, second homes, extensions and repeatable projects.
• Foundations and service connections on site, as for any home.
• Schedule and scope defined by contract.

In a printed system time is saved in the wall phase, not across the whole project: permit, foundations, services and finishes follow their own schedules.

In our 180 m² base case the internal estimate is about 198 days with the traditional method versus about 43 with the printed system. These are planning estimates, not a commitment: the final schedule is fixed by contract during the validation phase.

We do not quote a price per square metre without knowing the case: the cost of a printed house depends on variables that change from project to project, and a generic figure would be misleading.

After the study we issue a written fixed-price budget with itemised lines, so you can compare it with a traditional-construction offer of the same scope.

• Floor area, number of storeys and geometric complexity.
• Foundations: depend on the geotechnical study and the plot topography.
• Services and finishes: they usually weigh as much as the structure and cost the same with any system.
• Logistics: distance, access, transport of the printer and the mortar.
• Permit, technical fees, ten-year insurance and site management.

They are those set by the Building Ordinance Act (LOE, Law 38/1999) for any new home, regardless of the construction method. The periods run from the handover (recepción) of the works.

Ten-year insurance covers structural damage to the home and is taken out by the developer (except for self-build for own use). The buyer has two years from when damage appears to claim. Any additional commercial warranty is defined by contract for each project.

For the bank and the valuer the home is a home like any other: design, municipal permit, final completion certificate, new-build declaration and Land Registry entry. Mortgage valuation is carried out by approved valuation companies and relies on the comparison method or, where comparables are lacking, the cost method.

There are no long-term resale statistics because the technology is new and some lenders may be cautious. We recommend consulting your bank before signing, with the project and the system documentation; if your priority is minimum liquidity risk, a system with a longer track record remains the conservative option.

• Complete documentation and as-built records ease valuation.
• LOE and ten-year insurance as for any new build.
• Market value depends on location and quality, as for any home.

Before starting we hand over a verifiable quality file that is completed during and after the works, so you can check every claim against a document.

• Datasheet and batch certificate of the mortar.
• Independent tests of the test panel (specimens and cores).
• Endorsed structural calculation of the reinforced concrete core.
• Print-parameter log for each element.
• As-built documentation of the finished building.
• Control plan with the testing schedule.
