Overview

Barnhaus 102 is the 101 plan with a whole extra floor beneath it. The three levels above grade are the same engineered home: double-height living room under a glass gable, kitchen, office, first-floor guest suite, primary suite and two bedrooms upstairs, heated attic. Under them sits a 1,997 SF finished lower level that turns the house into 6,400 SF of heated space.

The lower level is planned as the house's second life: a 610 SF home gym, a 465 SF home theater, a 297 SF lounge, a sauna, and a fifth bedroom with its own bath and closet. It works as a complete guest or in-law apartment, or as a teenager's floor. Storage and a utility room take the mechanical load off the floors above.

Outside, the facade moves from charcoal to a warm bronze porcelain with the thermowood gable carried through, and the same 2,200 SF of terraces wrap the second floor and the rear of the house at grade. The house number is set into the facade in raised steel numerals.

Every dimension on this page comes from the home's digital twin, the complete 3D model from which the steel is manufactured. What you're reading is not a rendering of an idea. It's the description of a fully engineered building.

Built to last for centuriesSteel frame, MgO sheathing, porcelain skin. Nothing organic to rot, warp, or feed termites. A structure that doesn't move, so it doesn't crack.
Non-combustible from foundation to roofConcrete, steel, mineral board, and fired porcelain. Insurers notice, and so does a family in a wildfire year.
Designed completely before it's builtA millimeter-accurate digital twin in which every window, duct, cabinet, and outlet is placed before anything is manufactured. The steel is cut from that twin.
Sealed, ventilated, healthy airA closed envelope with continuous exterior insulation and a Zehnder heat-recovery ventilator exchanging the home's air six times a day.

Lot requirement: the footprint is roughly 63'-3" × 67'-9". Allowing for typical setbacks, Barnhaus 102 fits on a lot 100' × 140' or larger. We'll confirm fit against your specific lot and zoning during the consultation.

How it's built

Every ZaraNova home is built in layers, each doing one job. Read from the inside out.

Cold-formed steel frame

Light-gauge galvanized steel profiles, joists, and trusses, manufactured on CNC roll-forming equipment directly from the digital twin. Each piece is labeled and packed in assembly order. Steel doesn't shrink, swell, warp, or rot, so walls stay laser-straight and floors never squeak.

Manufacturing · SteelModu ↗

MgO board sheathing

Magnesium-oxide board replaces plywood and OSB on walls, floors, and roof. It's non-combustible, immune to mold and moisture, and bonded to the steel joists with structural silicone, which is why the floors have zero movement.

Supply · Megaboard ↗

Continuous exterior insulation

Closed-cell spray foam applied to the outside of the sheathing wraps the whole structure in one unbroken layer: insulation, air barrier, and vapor barrier at once. Applied outside the profiles, it eliminates thermal bridging through the steel and moves the dew point outside the wall, so condensation never forms inside it.

Installation · Foamus ↗

Ventilated porcelain cladding

Large-format porcelain slabs hung on the patented Megabai wall-furring system, with a ventilated cavity behind them. Porcelain is indifferent to sun, rain, heat, and frost, never fades, and comes in almost any look: slate, stone, marble, or the wood-plank finish of the gable.

System · Megabai Wall Furring ↗

Insulated sandwich roof

Steel roof trusses carry insulated sandwich panels, a rigid insulating core between two metal skins, finished with a standing-rib metal roof. One factory-made component replaces decking, underlayment, insulation, and roofing.

Detail · Spec sheet on request

Fresh-air system

A Zehnder heat-recovery ventilator continuously replaces stale indoor air with filtered outdoor air, transferring only heat between the two streams, never moisture. The home's full air volume is exchanged six times a day, quietly, in every room.

System · Zehnder ↗

Permit fees not includedMunicipal permit and review fees are paid directly to your jurisdiction under every option.

Delivery quoted separatelyFreight for Options 1 and 2 is quoted by destination and distance once we know where the home is going.

One digital twin, three optionsAll three start from the same engineered model, so moving from a kit to an installed structure, or to a turnkey home, is a change of scope, not a redesign.

Customization

Love the concept but need changes? That's normal. Most of our clients start from Barnhaus 102 and adjust it: swap the theater for a second office, add a wine room, enlarge the gym, or change the facade to the charcoal of the 101.

Because the house lives as a digital twin, changes are made in the model first, and the steel is manufactured to the new version. Small modifications are quick. Larger ones are re-engineered and re-priced before anything is fabricated. Either way, you see the exact result before a single part is cut.

Facade color, porcelain finish, interior door style, flooring, and bathroom fixtures are all selections you make with us. They don't change the structure or the price of the shell.
