The greatest advantage of preHAUS homes is their industrial production. They are well-planned, executed with millimetric precision, and produced under strict quality control at every stage—on the construction site, only the wall elements are assembled. And it’s so fast, it might just amaze you.
Unlike traditional construction methods that are built outdoors on-site, preHAUS’s prefabricated houses are constructed industrially in their own factory, independent of weather conditions. The walls are produced using high-tech machines programmed with millimetric accuracy, using only wood and sustainable building materials. This means your advanced rough-in house is delivered to you fully prefabricated—complete with windows, a front door, and pre-installations—flawlessly, thoughtfully, and ready to go. Quick, precise, smooth, and secure—that’s how the assembly of a preHAUS home is carried out on-site.
The assembly and logistics process works perfectly. The finished wall elements, with windows already installed, arrive at the site complete—including the roof. Our experienced assembly team ensures flawless installation. Including the roof, preHAUS needs only about 2 to 4 days for the full assembly, and homeowners watch with excitement as everything comes together perfectly.
Thanks to preHAUS’s advanced manufacturing and assembly methods, the dream of owning your own home can be realized within a short and efficient construction period. From planning to final completion, preHAUS’s project consultants will be happy to support you every step of the way to ensure a fast and seamless process.
The custom production of a prefabricated home begins with the work of experienced civil engineers.
A 3D model of the house is created based on the architectural drawings, and all components required for assembly at the factory are calculated. Individual customer requests are taken into account and directly integrated into the planning process. Every wooden beam needed is defined in the computer, along with its specifications and dimensions. A complete parts list is then sent as a digital record to the factory workers.
The data obtained from the planning unit is transferred to the cutting and sizing system for execution.
In the computer-controlled timber cutting system, wood is cut with high precision and millimetric accuracy. Thanks to accurate planning and precise cutting, not only is the highest level of precision achieved, but wood waste is also significantly reduced. After the cutting unit, each wall stud, ceiling beam, roof beam, or floor beam of the prefabricated home is forwarded to the respective production lines for the roof, ceiling, and walls.
On the timber construction line, the structural framework of exterior walls, interior walls, and intermediate floors is assembled.
Previously cut wooden components are brought together and joined here according to the specifications of each element. For this reason, the construction line is the heart of production—where the structural framework, wall studs, and beams come together. A high level of automation combined with the expert knowledge of the workers creates a symbiosis of technology and craftsmanship that guarantees top quality.
The completed timber construction moves on to the next line.
Here, one side is covered with panels, and the inner sections are filled with thermal and acoustic insulation materials. At this stage, the walls are equipped with both sound and heat insulation.
Before the other side of the exterior and interior walls is closed with wooden panels, the heating system, electrical wiring, and plumbing installations are completed.
Heating pipes, concealed fixtures and sanitary ware, toilet cisterns, and sound-insulated waste pipes are installed. The electrical wiring is laid using halogen-free, fire-resistant conduits. These preparations in the factory significantly speed up the on-site delivery of the home.
At this stage, the walls—now complete with installations and insulation—are precisely sealed using pre-cut panels and pneumatic nail and screw machines.
Thanks to the layered use of wood-based materials and other panels, even the heaviest objects can later be securely mounted onto the walls.
The walls are transferred to the next line via a rail system, where windows and doors are installed.
They are mounted under optimal factory conditions and finished to perfection. Later, the building’s airtightness is tested again on-site (blower door test). Thanks to high-performance insulated glazing, optimal thermal protection is ensured in the prefabricated home.
The exterior walls now move on to the insulation and plastering line.
Here, mineral wool is first applied as exterior insulation. Over the mineral wool, a high alkali-resistant mesh is added, followed by crack- and impact-resistant mineral plaster layers. This process ensures high quality and provides a weather-resistant façade. It also significantly accelerates the overall construction process of preHAUS homes. In the end, only final touch-ups remain after on-site assembly is completed.
The completed roof panels now feature a breathable, high-performance waterproofing layer.
This means the roof is watertight and protected from the elements from day one. Producing the roof components in the factory allows the home’s roof to be covered very quickly on-site, significantly reducing construction time. On-site, roof tiles or roof panels are placed directly onto the pre-installed roof battens, saving both time and cost.
Decorative and façade construction elements are painted using weather-resistant, solvent-free varnishes and paints.
This ensures that the wood remains protected against the elements for a long time, while also preserving its natural appearance and giving the prefabricated home a distinctive charm.
The house walls—up to 13 meters in length—are securely wrapped and protected from wind, water, and dust, and delivered to the construction site along with all necessary materials.
In the factory, the walls are carefully and securely covered using recyclable film to ensure maximum protection during transport.
You can start enjoying your preHAUS prefabricated home in no time.
Your house is assembled within just a few days and completed safely in a short period—completely unaffected by weather conditions. In traditional construction, the overall building process is often prolonged due to factors like complex procedures, poor workmanship, weather delays, and concrete curing times.
With preHAUS, none of these issues exist—you can move into your home quickly, comfortably, and stress-free.
