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.

50% on site and 50% in factory.

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.

Every BIOBUILDS home is built on a Passivhaus-certified construction system we developed in-house, engineered for unmatched efficiency: ~15 kWh/m² per year, versus ~350 for an average home. Energy demand drops so low that going off-grid with solar becomes trivially easy.

The most complex sustainability calculation for buildings. Every material, every emission, independently verified.

Modular's EPD proves it is more than sustainable. It is carbon negative, actively contributing to a healthier planet.

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.

A smart ventilation system with an integrated heat pump. All-electric, ultra-efficient.

The Passivhaus envelope combined with triple-glazed windows that act as solar radiators means the ventilation system alone heats the entire home.

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 every interior surface, smart systems, ventilation with heat pump, and a fully fitted bathroom included. Or semi-finished: the complete Passivhaus-certified envelope, exterior fully finished, with windows, prepared electrical and plumbing installations, ventilation, and a fully waterproofed bathroom. The interior fit-out is yours.

Insured transport to your plot can be included. On-site assembly is not part of our delivery; it can be fully handled by local partners, using our complete assembly documentation. Both options, models, and pricing transparently in our catalog.

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.

You receive the complete permit-ready documentation from us: plans, structural calculations, Passivhaus certificate, and EPD. With it, your architect or planner can apply for the building permit at your municipality, like for any other home. Requirements differ by location, so it's important to check them early.

It's also Zero-Energy ready if your area allows it, thanks to ultra-low energy demand.

We deliver across Europe.

Transport costs depend on your location.
