MODULAR

BIOBUILDS was born in 2012 from a father's desire to build the best home for his family. Today, it is redefining how homes are designed, built, and lived in.

We merge radical innovation with sustainable design to build the future.

First, we moved the entire construction process from site to factory, minimizing both human error and delays. Secondly, with the newfound precision and standardization, we adopted the world's strictest standards: Passivhaus for efficiency and EPD for sustainability.

BIOBUILDS homes deliver a groundbreaking set of advantages. Energy: ~95% lower consumption. Speed: move-in 3 weeks, instead of 3 years. Sustainability: built with over 98% natural materials.

This is so much more than a home; it's a blueprint for a healthier, more sustainable future. Discover the future of living at biobuilds.com.

The world's strictest energy efficiency standard, developed at the Passive House Institute in Darmstadt, Germany.

Not a design philosophy. An engineering specification, audited line by line. Wall U-value under 0.15 W/m²K. Airtightness under 0.6 air changes per hour at 50 pascals, blower-door tested. Triple-glazed windows under 0.8 W/m²K. Heat recovery ventilation above 75%. Thermal bridges effectively eliminated. Either the building meets the math or it doesn't get certified.

The average European home consumes 350 kWh/m² per year. A new conventional build, around 150. A Passivhaus home sits at 15.

MODULAR by BIOBUILDS is a fully Passivhaus Darmstadt-certified modular construction system. The first of its kind in the world.

The problem with most Passivhaus projects is cost. Building to this ground-breaking level of efficiency requires advanced materials science and project design. MODULAR solves this through prefabrication.

Prefab is the principle that a home should be built where it can be built well: indoors, with precision, before it ever touches your land.

Traditional construction is exposed to weather, fatigue, improvisation, and a chain of subcontractors, none of whom answer for the whole. The result is the industry we all know: delays, defects, budgets that drift, and years of your life spent watching it happen.

Prefab moves that process into a factory. Quality is controlled, not promised. Materials are protected, not soaked. Tolerances are measured in millimeters, not centimeters.

The share completed in the factory depends on the construction system.

But we wanted to take it further.

Modular is the most advanced form of prefab. ~99% built in-factory.

Instead of shipping flat panels for on-site assembly, we ship complete rooms, with walls, insulation, wiring, plumbing, and finishes already in place. 10 days in the factory. 2 days in transport. 3 days on site. Move-in in 3 weeks.

Modular isn't just faster. It's a new paradigm to deliver a home that's efficient, healthy, and sustainable, at scale.

Standard MODULAR models target around 15 kWh/m² per year for heating, supported by our Passivhaus-certified construction system. This low demand makes off-grid living realistic with solar generation and storage sized for the site and household. Infinity has a separate glass-front energy specification.

An Environmental Product Declaration is an independently verified assessment of a product’s environmental impacts over the stages declared in the document.

BIOBUILDS’ external-wall EPD records a carbon-negative production stage: -101 kg CO2e per m² of the declared wall, from raw materials through manufacturing.

The synthesis. Passivhaus efficiency, prefabricated precision, modular speed, EPD-verified materials, in one home.

All under five unwavering principles: prefabricated. Made in Europe. Efficient. Healthy. Sustainable.

Timber-frame. 98% organic, sustainably sourced. Wood fiber insulation, triple-glazed windows.

The most advanced building material isn't new. But it is healthy. It is renewable. It's wood.

Zehnder heat-recovery ventilation works with a heat pump for efficient, all-electric heating and cooling. The equipment is specified for your model and configuration.

The Passivhaus envelope and triple-glazed windows keep heating demand low. The ventilation and heat-pump system supplies the remaining heat.

Depending on your preferences or location, we can add floor heating or other complementary systems.

The roof has a 3–5 degree slope despite looking seemingly flat. Water drains naturally.

EPDM membrane, the premium standard for flat roofing. Simulated load capacity over 300 kg/m² (EU average: 80 kg/m²). Durable, weatherproof, maintenance-free for decades.

Our system is designed and simulated for a lifespan of over 80 years: a 35 cm Passivhaus-certified wall system, airtight, weather-protected, and fully factory-built.

For comparison: over 85% of new single-family homes in Sweden are timber-frame, with lifespans of over 70 years. Direct testing and internal simulations show that the precise, airtight, moisture-protected Passivhaus construction significantly extends lifespan; exact quantification at scale is not yet available.

Two options. Turnkey: fully finished, with interior finishes, smart systems, ventilation with heat pump, and a fully fitted bathroom. Kitchen connections are prepared; kitchen furniture and appliances are not included. Or Exterior Finished: the complete Passivhaus-certified envelope, with windows, prepared electrical, plumbing and ventilation installations, and a fully waterproofed bathroom. The interior fit-out is yours.

Prices include 23% Irish VAT and an estimated €20,000 before VAT for partner transport to Ireland. Transport may vary slightly with season and partner pricing. Installation on prepared ground screws is included; foundations, connections and site works are quoted per project.

Through your bank, like any other home. From us you receive the complete financing file: fixed price, specifications, Passivhaus certificate, and EPD.

Ask your bank about programs for energy-efficient construction. The Passivhaus certificate serves as an audit-ready proof of energy efficiency you can submit; depending on the program, further documents may be required.

Ireland’s Class 3A exemption can replace planning permission with a 14-day notice for qualifying rear-garden homes of 32 to 45 m². Wanderlust’s Irish eligibility and any required adaptations are still being assessed. We confirm the planning route for your site before you order.

Outside the exemption, we provide the complete permission-ready documentation: plans, structural calculations, Passivhaus certificate and EPD.

We deliver across Ireland.

An estimate for our partner’s transport is included in the displayed price. It may vary slightly with season and partner pricing. You can arrange transport yourself and remove this allowance.
