Stages of building a prefabricated house – step by step
Stages of building a prefabricated house – step by step
From dream to assembly – this is what prefabrication looks like in practice
A prefabricated house doesn't happen overnight, but the process can take just a few weeks —provided you plan it well. In this article, I'll show you exactly what building a prefabricated house looks like, step by step—from the investor's perspective.
🔟 10 stages of building a prefabricated house
1. Selecting a plot
Start with a plot of land – ideally with electricity and planning permission (WZ or MPZP). Check road access, land use, and local regulations.
2. Selection of design and technology
You can choose a catalog design or a custom one. At this stage, you also decide: wood, expanded clay, or another technology? Flat or pitched roof? Attic?
➡️ See how much an individual project costs
3. Prefabrication pricing and contract signing
You'll receive a quote broken down by stage: prefabrication, assembly, transport, shell, developer, and turnkey. Note: some companies don't provide everything – ask for details!
4. Formalities and notifications/permits
For houses up to 70 m² it is possible to build "on notification", but the formalities still apply (map, notification, construction log, etc.).
5. Construction of the foundation
The most common foundation used is a slab – quick, stable, and prefabricated. Cost depends on the soil, reinforcement, insulation, and labor.
6. Production of house elements
Walls, ceilings, and roofs are manufactured in a factory according to the design. This takes 4–8 weeks. During this time, you prepare the plot and the foundation.
7. Transport and assembly of prefabricated elements
The house "arrives" at the site. Assembly can take 2 to 5 business days. Transportation, crane, and logistics must be planned in advance.
8. Closing of the shell
Once the house is assembled, windows, doors, and a roof are installed—this is called the closed shell stage. Some companies end their cooperation at this stage—with us, you can move forward.
9. Developer or turnkey finish
Plumbing, heating, flooring, bathroom, painting – everything that makes a home ready to move in. You choose the standard and materials.
10. Acceptance of the house and moving in
Finally, you check compliance with the contract, take delivery of the house, and you can start arranging the garden, terrace, and... living in peace.

👉 From decision to move-in: 3 to 6 months , depending on technology and formal qualifications
✍️ Comment by Dorota Burzec
"I've seen investors wait a year for a foundation. And others who built a house in 12 weeks. The secret? Well-planned prefabrication + a well-coordinated team. That's why I created Marysia Houses – to simplify what can be simplified and speed up what can be sped up."
❓FAQ – investors' most frequently asked questions
Can I start building a prefabricated house without a permit?
Yes, if it is a house up to 70 m², single-family, detached, on a plot compliant with the development plan or local spatial development plan.
Can I make the foundation myself?
Yes, but you must meet the requirements of the prefabricated manufacturer - otherwise the house will not be built.
Do I have to be present at the construction site?
No, but it's worth showing up on the day of installation – it only takes a few days and it's really impressive.
