Exterior Finished
Be your own designer
Same Passivhaus quality. Your interior, your way.

More than a home.
A 35cm wall of C24 timber, STEICO wood-fiber insulation, Agepan breathable sheathing, and airtight intelligent membranes, engineered as a single Passivhaus-certified system with zero thermal bridges (junction Ψ-values ≤ 0.01 W/m·K, certified). A system built and certified to Europe's strictest building standard.

STRUCTURE
Passivhaus-certified system
Considered by the Passive House Institute in Darmstadt across over 2,000 tracked parameters. Surpasses Europe's 2050 standards: certified to the strictest standard of efficiency (Passivhaus), and assessed through the most complex sustainability calculation (EPD).

MATERIALS
Natural to the core
98% organic materials by volume. FSC-certified C24 timber frame, STEICO wood-fiber insulation, and breathable Agepan sheathing, every layer sourced from managed European forests. A home grown from the ground up.

GLASS
Triple-glazed. Secured. Laminated
Three layers of tempered, laminated glass with warm-edge spacers. Enjoy panoramic views and pure sunlight with a U-value of 0.50, among the best in the industry.

FRAME
Genesis 90. Passivhaus certified
Aluminium frames so efficient they disappear into the wall. What remains is glass, light, and a Passivhaus-certified design that holds for decades.

So natural, so resilient
Built for decades. Designed with minimal maintenance. Higher load-resistance than the average house, all from natural materials.

SHOU SUGI BAN
Yakisugi
Ancient Japanese preservation by charring. Resists weather, insects, and rot for decades with very low maintenance.

THERMOWOOD
Lunawood
Grown and strengthened in the harsh climate of Finland, the renewable Nordic forest provides us the best wood material, only enhanced with heat and steam.
Available in two tones: blonde or noir.

ROOF
Not quite flat
Low-slope roof with a minimalist profile and increased load capacity up to 300 kg/m², compared with around 80 kg/m² in standard residential roof calculations.

PROFILE
Minimalist silhouette
Integrated gutters. Seamless drip edges. Water channels away from the facade while seamlessly integrated. Every line intentional, every detail invisible.
Installed before your finishes.
Cables and conduits are included as standard. Water installation and electrical panel installation are preselected in the starting price. Remove either option in the configurator to reduce the price. The ventilation unit, ducts and their installation in the house are a separate optional upgrade.

ELECTRICAL
Prepared inside the walls
Cables and conduits are installed in the factory and included as standard. The electrical panel is an optional upgrade. Final sockets and switches follow your interior finishes.

PLUMBING
Ready for your fixtures
All water installation inside the walls, including the Grohe concealed WC tank, factory-fitted with PPR/PEX piping to EU standards. All that is left is your bathroom furniture.
Installations are prepared to EU standards. Images shown are examples and may vary by region or project. Please inform us during the architecture phase if local adaptations are required.

Bathroom.
Ready for your touch.
Waterproofed bathroom walls and floor are standard. Add the plumbing installation for pipes and concealed WC cisterns, ready for your fixtures.

INTERIOR
Your canvas.
Your rules.
Passive House approved OSB panels with no excess formaldehyde off-gassing line every interior surface. A blank canvas engineered to accept paint, wall panels, and parquet directly. No drywall, no dust, no limits.
Be your own interior designer.
Three steps between OSB and the interior you have always imagined. Hours of simple work, not weeks of construction. Passivhaus-certified bones, finished with your personal signature.

CEILING
Start with the ceiling
One coat of primer, one coat of finish. A roller, a tray, and a free afternoon. That is the entire ceiling, done.

WALLS
Make it yours
Wall panels bond directly to the OSB. No frames, no screws, no mess. A room transforms in hours, and you chose every texture.

FLOOR
Walk on it
Parquet planks bond directly to the OSB. Lay, tap, and walk on real wood the next morning.

Exterior Finished FAQ
GENERAL
Exterior Finished means the exterior is fully finished: structure, insulation, windows, cladding and roof. Cables and conduits are included as standard. Water installation and electrical panel installation are preselected and removable. Ventilation equipment and ductwork are an optional upgrade.
The interior walls, ceilings, and floors are premium OSB panels, ready for you to apply paint, wall panels, and flooring.
See turnkey optionNot necessarily. The three finishing steps are designed to be approachable for first-time DIYers. Basic DIY skills are enough for many interior finishes.
We provide detailed video guides, material lists, and email support throughout the process.
Contact usAbsolutely. Many customers hire painters for ceilings and handle floors/panels themselves.
We can connect you with experienced contractors in your region if needed.

Cables and conduits are installed in the factory and included as standard. The electrical panel is an optional upgrade, installed in the factory. Final sockets and switches are fitted after your interior finishes. A qualified electrician completes the site connections and checks.
Water installation and electrical panel installation can each be removed in the configurator. Cables and conduits remain included as standard. The ventilation unit, ducts and their installation in the house are selected separately.

EPD HUB-0050 covers the MODULAR external-wall assembly assessed in 2022 and is valid until 01.06.2027. It uses the earlier cellulose insulation; current homes use STEICO wood-fibre insulation. The material principles are similar, but calculated impacts can differ. The −101 kg CO₂e/m² result applies to the declared wall in production stages A1–A3, not automatically to the current assembly. External-wall EPD HUB-0050 (PDF)
The 350.4 t figure is an illustrative Bloom 190 scenario over 50 years: 294.1 t of modelled avoided operational CO₂ plus 56.3 t of CO₂ stored in the assessed wall, floor and roof panels. Energy savings use (150 − 30) kWh/m²/year × 0.75 × 190 m² × 50 years, multiplied by 0.344 kg CO₂/kWh, the German 2025 electricity-generation factor held constant for this illustration. Panel carbon storage uses EPDs HUB-0050 and HUB-0048. Stored carbon and avoided emissions are different quantities; their sum is not a verified whole-building lifecycle saving. Area, climate, energy source, use, material changes and end of life affect the result. Calculation and assumptions
