You are investing in the world's most rigorous building certification. Over 2,000 parameters are verified by the Passive House Institute in Germany. In practice, this means: up to 10x lower energy bills, significantly longer lifespan, constant fresh air ventilation, and a home that feels like a thermos, warm in winter, cool in summer, silent inside.

Passivhaus certified timber-frame system, built on 35cm structure. Exceptional strength, ground-breaking efficiency.

High-performance STEICO wood-fiber insulation, λ ≈ 0.036 W/m·K.

Over 85% of new homes in Sweden are built on timber-frame, with an average lifespan of 70+ years. MODULAR uses a significantly improved timber-frame structure (Passivhaus certified), fully airtight and incredibly efficient, which can significantly extend its service life. The minimum estimate is 80+ years.

Both are possible. Over 80% of clients choose Modular as a permanent home. Sanctuary 142m² Semi-finished model is the most popular among families.

Nest 24 m² (6.3×3.8 m). Wanderlust 48 m² (12.6×3.8 m). Serenity 95 m² (12.6×7.6 m). Sanctuary 142 m² (12.6×11.4 m).

Guide: about €1,000/m² semi-finished to €2,000/m² for a fully finished model plus smart systems. Compare this against ongoing savings. EU average reference: ~€1,800-2,200/m² finished.

It quantifies the life-cycle impact. MODULAR is carbon-negative, at −101 kg CO2e per m².

On the BIOBUILDS website and the public pages of the issuing institutes. This includes Passivhaus certification and EPD International.

Yes. Ultra-low consumption enables compact PV and battery systems for autonomy.

It has a very high resistance 35cm prefabricated structure with ground-screw foundations to dissipate shocks and vibrations. It offers significant resilience to natural disasters.

Factory tests reach over 90 minutes on wall fire resistance. While it can vary by location, the natural resistance of the cladding and the wall's airtightness is undeniable.

C24 FSC timber + ultra-efficient wood-fiber insulation + ECO OSB without formaldehyde adhesive + smart vapor control membrane. In total, a Passivhaus certified system achieving a ground-breaking U-value ≈ 0.14 W/m²K.

Timber frame. The most advanced building material available, timber insulates naturally, is exceptionally strong, stores CO2 instead of emitting it, and creates naturally healthy indoor conditions.

Over 98% organic materials. Your home breathes naturally, regulating humidity, purifying indoor air, and creating a living environment that conventional buildings simply cannot match.

Approximate airborne sound insulation of 54 dB. This is comparable to professional audio spaces.

Controlled outward drying via a smart membrane and carefully selected structural panels. The risk of condensation and mold is eliminated.

Yakisugi or Lunawood. Both offer high protection and durability.

A full catalog of premium organic finishes is available during the design phase. These are included at no extra cost for the turnkey option, unless specified otherwise.

A controlled air cavity that evacuates moisture and protects the structure long-term. Also known as rainscreen cladding.

All installations included. For modules with a kitchen, rough-ins are pre-installed and ready for cabinets and appliances.

Organic finish. Low maintenance. A typical recoat is needed every 3-6 years, versus 1-2 years for conventional synthetic finishes.

Materials are selected for easy cleaning and durable, modern natural aesthetics.

Smart external blinds are available as an option. They are passive-house compatible and can block up to 99% of UV. Smart control is available.

A low slope of 3–5°. This provides a flat look with efficient drainage.

Yes. Ventilation reduces moisture and overheating and extends the life of the roof covering.

Firestone EPDM membrane. Load capacity over 300 kg/m².

Yes. The structure supports green roofs and PV. Dimensions are engineered to the required loads.

Concealed gutters are located within the ventilated facade. Optional collection for reuse is available.

Engineered beyond national standards for extreme loads, ensuring high safety in use. Est. at 300kg/m² for the roof load versus EU average of 80kg/m².

It repeatedly beats the Passivhaus standard of ~15 kWh/m² per year according to Passivhaus simulations. This is about 10 times more efficient than an nZEB (nearly zero-energy building) and the average new-build in Europe. Performance varies by climate, orientation, and use.

Below 0.6 h⁻¹ (air changes per hour) tested or simulated. It has been measured as low as 0.1 h⁻¹ on real projects, up to 100x more airtight than conventional builds. This is ground-breaking performance that directly translates to near-zero energy loss.

The construction system. It confirms efficiency, airtightness, and zero thermal bridging.

According to Passivhaus simulations: Modular reaches a ground-breaking 15 kWh/m² per year. In comparison, the EU detached house average is ~350* kWh/m² per year. This ensures a dramatically lower energy consumption. Values vary with location and positioning.

Up to 95% savings. This depends on consumption, climate, and orientation.

Super-insulation, smart shading, and heat-recovery ventilation maintain stable indoor comfort even during extreme heatwaves, without air conditioning. Needs vary by climate.

Super-insulation and smart heat-recovery ventilation maintain stable indoor comfort even during harsh winters, with minimal energy input. The home stays warm with a fraction of the heating a conventional house needs. Needs vary by climate.

It cuts infiltration. Typical houses can reach losses up to ~20 ACH (air changes per hour) under a standard airtightness test. MODULAR repeatedly reaches below 0.6 ACH. A 33x difference!

Triple glazed, laminated, tempered glass. Ground-breaking Ug of ≤ 0.5 W/m²K. And Passivhaus-certified ultra-efficient aluminum frames.
