BioBuilds' standard modular homes cost €2,411–2,667/m² in Turnkey, including an illustrative 19% German VAT; site costs are separate. This range uses nominal exterior areas. The homes use a Passivhaus-certified building system; the standard models target around 15 kWh/m² per year for space heating. Compare each manufacturer's finish, floor-area definition, transport and VAT basis before comparing prices.
Manufacturers offer different designs, specifications and finish packages. This guide compares published prices and explains the separate costs needed for a complete project.
For BioBuilds' own published model prices, Exterior Finished and Turnkey, see the 2026 prefab price guide; this article compares the wider market.
Understanding modular home pricing requires distinguishing between headline prices and total project costs. A shell quote leaves interior work to be priced separately; a Turnkey quote includes the manufacturer's specified interior package. The difference matters enormously for budgeting and comparing options.
Three price reference points
Published model prices, market surveys and individual quotations answer different questions. Understanding where manufacturers position themselves helps evaluate whether you're comparing equivalent products.
BioBuilds: published model prices
BioBuilds manufactures timber-frame homes in Moreni, Romania, with wood-fiber insulation and a Passivhaus-certified building system.
BioBuilds delivers homes built on a Passivhaus-certified building system at €2,411–2,667/m² in Turnkey, including an illustrative 19% German VAT.
German prefab market: asking prices
For Germany, Fertighaus.de places mid-priced turnkey prefab offers at €2,500-€3,000/m². This is a German portal benchmark, not a Europe-wide modular price band.
Bespoke homes: individual quotations
Huf Haus and Baufritz offer individually designed homes. Huf Haus prices each project individually.
Price tier doesn't directly correlate with energy performance or build quality. Always compare certification levels, not just prices.

BioBuilds advertises a three-week build timeline. The offer and individual contract confirm the schedule for each project; planning, permits and site preparation must also be scheduled.
Manta North: Scandinavian design from the Baltics
Manta North manufactures in Latvia and offers CLT homes with fitted interiors. Its online configurator allows customers to customize layouts before purchase. Its support page states 12-16 weeks from contract and first payment, with shipping to EU countries priced separately.
Manta North: published Full Mode prices, transport extra; VAT basis not stated on the product pages:
German manufacturers: WeberHaus and Bien-Zenker
Germany's established prefab manufacturers offer extensive customization. WeberHaus has operated for more than 60 years. Its generation 205 example above uses the manufacturer's Bad komplett finish, including the slab. Bien-Zenker was named Unternehmen des Jahres 2025 in its sector, based on price, trust, popularity and social responsibility.
Customization and finish choices affect the project schedule. Bien-Zenker states three days of factory production, with the full planning and construction process taking several months.
Ultra-luxury: Huf Haus and Baufritz
Huf Haus offers individually planned timber-and-glass post-and-beam homes. Baufritz publishes the Heimat 4.0 example shown above; its quoted area is net floor area, not DIN living area.
For a useful comparison, request the same floor-area definition, finish level and site scope from each manufacturer.
What's included (and what's not)
Price comparisons become meaningful only when you understand what each quote includes. Land, foundations, connections and the agreed finish scope determine the total project cost.
Typically included in turnkey quotes
BioBuilds Turnkey includes the complete structure and envelope, interior finishes, flooring, fitted bathrooms, electrical and plumbing installations, lighting and ventilation. Kitchen connections are prepared; kitchen furniture and appliances are not included.
Commonly excluded items
BioBuilds' module price excludes land, foundations, utility connections, permits and site works. The total-cost guide itemizes these costs. Wanderlust costs €128,000 in Turnkey, including an illustrative 19% German VAT. Its site-cost estimate starts at €32,400, including an illustrative 19% German VAT, excluding land and transport.
BioBuilds includes transport in Irish storefront prices and quotes it separately by destination elsewhere. The buyer arranges unloading, the crane and positioning on the foundation, as set out in the delivery terms. On-site assembly is arranged by the client with BioBuilds' local partners at no extra cost. Budget landscaping, driveways and furniture separately.
Hidden costs that surprise buyers
Check the following site conditions before finalising your budget.
Foundation complexity
Rocky ground, slopes and high groundwater can require additional earthworks or a different foundation design. A site survey conducted before purchase can reveal these issues early.
Access and delivery constraints
Modular homes arrive on specialist transport. Narrow roads, tight turns, low bridges, and overhead power lines can necessitate alternative delivery routes or specialized transport equipment. Access and crane arrangements should be assessed for the actual site.
Utility distance and capacity
Connection costs depend on the distance to utilities and available capacity. Rural sites may need a private water supply, wastewater treatment or off-grid power, subject to local approval.
Permit and regulatory requirements
Building permits themselves represent only part of regulatory costs. Some jurisdictions require architectural review, environmental assessments, or heritage consultations that increase costs and extend the timeline. Confirm separately who pays for energy assessments, any building certification and completion inspections.
Budget site work by item, not by percentage: BioBuilds' site-cost estimates start at €32,400 for Wanderlust 48 m² and at €60,300 for Sanctuary 142 m², including an illustrative 19% German VAT. The total-cost guide itemizes every line.
Total cost of ownership over 30 years
Initial purchase price tells only part of the story. For homes held long-term, energy performance affects total cost of ownership. BioBuilds' standard models target around 15 kWh/m² per year for space heating; actual performance depends on the project's design, climate and use.
What is Passivhaus?
The Passive House Institute sets a space-heating demand limit of 15 kWh per m² of treated floor area per year, or a heating-load limit of 10 W/m², alongside other criteria. Its published comparisons describe around 90% less heating energy than older housing stock, not a guaranteed bill reduction against a new home. BioBuilds homes are built on a Passivhaus-certified building system. Learn more in our detailed guide to Passivhaus certification.
Maintenance and durability
BioBuilds manufactures in controlled factory conditions. Its certified building system includes airtightness and moisture-management details. BioBuilds estimates an 80+ year design lifespan for the modular system, with FSC-certified C24 timber and wood-fiber insulation.
Resale value considerations
European Commission research links energy efficiency with property value, without establishing a universal Passivhaus resale premium. EU rules move from nearly-zero-energy new buildings, required by the end of 2020, to zero-emission new buildings from 01.01.2030, and from 01.01.2028 for buildings owned by public bodies. Future resale value still depends on the property and local market.
Regional pricing across Europe
Modular home costs vary significantly by country, reflecting differences in labor costs, regulatory requirements, and transport distances.
| Market | Published cost reference | Scope |
|---|---|---|
| Germany | €2,814/m² | Fertighaus.de median of 1,694 turnkey prefab offers, April 2026; house price only |
| France | €1,914/m² | SDES 2024 average for individually built houses; all construction methods, land separate |
| Portugal | From €157,000 | Rusticasa 114 m² example; base price excluding VAT; timber-structure assembly within 100 km |

BioBuilds manufactures its homes in Moreni, Romania. Compare the delivered project price, including local work and tax, with alternatives for the same plot.
BioBuilds includes transport in Irish storefront prices and quotes it separately by destination elsewhere. Unloading, crane work and positioning are arranged by the buyer under the delivery terms.
Financing options and incentives
Public programmes and some lenders offer support for qualifying energy-efficient homes. The benefit depends on the project, borrower and current terms.
German KfW programs
Germany's KfW 297/298 programme offers loans up to €150,000 per dwelling at its QNG funding level. Energy-efficiency and sustainability experts confirm the project requirements. Passivhaus system certification alone does not establish eligibility.
Austrian Wohnbaufoerderung
Austrian housing support varies by federal state and project. It can include subsidised loans or repayment support; eligibility and amounts follow the relevant state's rules.
Emerging Romanian incentives
Romania's AFM administers programmes supporting renewable-energy equipment. The 2026 battery programme targets individual prosumers. Equipment support is separate from financing a new modular home.
Private lender considerations
EU research reports associations between energy performance and mortgage risk. Products such as BCR Casa Mea Natura have their own property and borrower criteria.
Compare the purchase price, confirmed financing terms and expected operating costs over the same period.
Pricing a premium modular home requires looking beyond headline figures to understand total project costs, included features, energy performance, and long-term ownership economics. BioBuilds' Turnkey range is €2,411–2,667/m² including an illustrative 19% German VAT, based on nominal exterior area. Assess expected heating demand, maintenance and financing alongside the purchase price.
For buyers prioritizing quality and value, manufacturers that combine premium certification with efficient production offer a compelling proposition. BioBuilds is one example, with homes built on a Passivhaus-certified building system and priced at €2,411–2,667/m² in Turnkey, including an illustrative 19% German VAT. BioBuilds advertises a three-week build timeline and 98% organic materials by volume in the wall, roof and floor build-up; the individual contract confirms the specification and schedule.
