Hello everyone,
I would really appreciate answers to my questions and thank you in advance.
Current situation: Plot of land available (building plot with development plan)
Desired situation: Construction of a single-family house with a basement on the plot, including DEKRA construction supervision (inspection and approval of individual trades)
Below are the rough steps of building a house as I imagine them. Please feel free to add or correct the order.
1. Preliminary discussion with the preferred prefab house company
2. Inspection of the building structure and review of experience reports about the prefab house company
3. Review of the prefab house company’s financial situation
4. Initial selection of the offered equipment package for the interior & factory visit of the production
5. Decision made on the prefab house company
6. Architectural planning including soil testing and structural engineering analysis
7. Preparation of building plans, energy demand calculation, cross-section planning, living space calculation
8. Submission of building plans to the local authority (estimated approval time up to 3 months)
9. Loan application must be submitted and approved
10. After approval of the plans and loan application (9 months interest-free commitment period) signing the contract with the prefab house company (contract will be carefully reviewed regarding scope and completeness of trades)
11. Start of production by the prefab house company
12. Excavation, groundwork, and installation of water supply & drainage, internet, gas line
13. Basement construction begins, completed basement including insulation
14. Basement completed
15. After completion of house production, delivery, and assembly on basement slab
16. Shell structure erected
17. Roof frame installed
18. Interior finishing starts (electrical work, insulation, plastering, etc.)
19. House finished, final acceptance inspection
20. Move-in and completion of driveway, garden, etc.
Questions:
Regarding point 2: Is some kind of preliminary contract with the prefab house company already necessary here? The architect is unlikely to carry out their work without financial security.
Regarding point 14: Is it disadvantageous if the basement is completed and the house assembly takes place a week later?
- By when do I need to have secured financing from the bank at the latest? The 9 months from point 7 seem very tight to me! (Production of the house walls, etc., already takes several months.)
- Is it correct that payments to the prefab house company are only made after approval or acceptance by the DEKRA construction expert I commissioned?

Who provides the cost estimate for the construction project in this case?Either you or a reliable and dedicated homebuilding company.
However, I always strongly recommend handling the numbers yourself and also doing the calculations yourself (not through Axel).
It’s important to develop a feel for the costs. Ask to have the detailed costs for the prefabricated elements provided in writing. Study flooring and additional construction-related expenses.
Look into prices including installation, adhesive, trims, tools, etc., for the painting work.
With this information, you approach the bank before signing the house contract.

Can I still include these costs in the construction financing with the bank?You can round up generously everywhere and build a healthy buffer for any unexpected expenses.
Instead of budgeting 8,000, estimate 10,000; instead of 900, plan 1,500, etc. That worked great for us. In the end, everything was spent because the buffer was used for a stronger foundation slab.

You hire the architect. They will first roughly design how the house is supposed to look and estimate the approximate costs.I don’t see it that simply if you want to build a prefab house.
If it’s a good company, they have their own architects, or you should agree on such an independent step beforehand.
@TE You want a timber frame house? Which company?

You can also round up generously everywhere to create a healthy buffer for all kinds of unexpected expenses.Alternatively, there are many tips on this forum about how much buffer you should plan for, either in euros or as a percentage. We have now included various construction buffers (for selections, groundwork, initial connection fees, etc.) as well as a separate personal buffer that we don’t touch. The car, washing machine, smartphone, and so on always break down when you least expect it—sometimes even all at once!
Everyone told us that these buffers tend to be used up faster than you can imagine. So, we’re warned, but still want to make the most of our house budget... it’s a dilemma.

If it’s a reputable company, they usually have their own architects, or you should discuss such independent steps in advance. This also answers the question of how the process works with an architect during construction.

Hello everyone,
I have a question that fits very well with this topic. How early did you approach your building partners (such as prefabricated house suppliers or architects)? Do you think it makes sense to get the first quotes as early as about two years before the start of construction?
Thank you very much in advance for your answers.

Do you think it makes sense to get the first quotes already two years before starting construction?No. That’s too early. Too much can change in two years. Financing, for example, may not be secured yet, prices will fluctuate, tastes can change, and so on.
However, you can already start planning for yourselves and occasionally visit show homes to figure out what you do and don’t want.
Just my opinion.
