ᐅ What Happens When During the House Construction Process?

Hello dear community,
I am about to become a homeowner soon, but I still have some questions that my previous research has not satisfactorily answered.

Rough plan:
- Construction of a solid 1.5-story single-family house (approx. 140sqm (1507 sqft)) in the 03XXX area
- Installation of a ground source heat pump with boreholes
- Plot of land (905sqm (9740 sqft)) found and a notary appointment already scheduled
- A zoning plan (building plan / planning permission) is available for the plot, allowing two-story construction
- Other restrictions of the zoning plan do not hinder our planned development
- This was confirmed to us by the lady from the urban planning office; my wife and I also work in local government (so she probably won’t want to upset us 😉 )

The plot is the last available one in a new development area.

We also had a brief conversation with a planner, who immediately tried to convince us to build a house “one size bigger,” which again reassured me that the zoning plan restrictions will not be an issue for us.

So if we proceed with purchasing the plot soon, there should be nothing standing in the way of building “our dream home.”

However, as a layperson, I am still unclear about the exact process of building a house. What happens next?

1. Find plot – done
2. Own idea of the house – done
3. Check building feasibility – done
4. Purchase plot – almost done
5. Select planner – done
6. Have planner design floor plan – open
7. Submit application for building permit / planning permission – open
8. ???

But what happens after the building permit / planning permission is granted?
Are the contracts awarded, and everything proceeds as planned?

No. ?. Soil excavation and foundation slab construction
No. ?. Borehole drilling for geothermal probes and laying pipes to the house
No. ?. Laying utilities to the house (connections are available in the street)
No. ?. Building up the walls of the house
No. ?. Installation of underfloor heating and heat pump
No. ?. Construction of the roof frame / roof covering
No. ?. etc.

My goal is to avoid mistakes so that later on, nobody says we could have done this earlier and now need to redo it. I also want to avoid any delays on site because I forgot to apply for something and the builders can’t continue until it is done.

The sequences I have found on the internet all read like this:

Find plot, buy, design, building permit / planning permission, build house, move in, done...

Try searching for a construction schedule in the images: there you can see the sequence of trades at other building sites of construction companies, but you don’t necessarily have to apply this sequence exactly to your own house build. Otherwise, it is the site manager’s responsibility to determine the order (and of course, how much time the contractors can allocate to your project).

Somewhere the financing still has to be arranged?

As far as I have read, I need to take the planner’s documents to the bank...? Then the financing will be arranged. Since we both earn a decent income and are generally very careful with our money, we are fortunate enough to be able to manage the house construction without a mortgage from the bank.

The relatively low costs for land and construction, compared to other regions, obviously work in our favor.

The price for our plot is about 30 Euros per square meter (around 2.79 USD per square foot). For plots from the city, it would have been about 20 to 25 Euros per square meter (approximately 1.86 to 2.32 USD per square foot).

I found this overview during my search:

House Construction Phases
  • Earthworks and laying of main utility lines
  • Foundation slab and shell construction of the basement
  • Shell construction of the floors with subsequent structural inspection
  • Carpentry work and roof framing
  • Installations, plumbing, windows, heating
  • Interior plastering
  • Screed
  • Exterior plastering
  • Floor coverings, final installation of electrical wiring, bathrooms, heating
  • Painting work
  • Exterior landscaping, final house cleaning
  • Final inspection
Would you say this roughly fits?

Sorry, I don’t quite understand that...

If you have enough savings to pay for the house and don’t need a loan, what do you want from the bank?

In that case, you should rather clarify the payment terms with the general contractor (GC) or subcontractors—they often require a financing confirmation from the bank.

  • Earthworks and laying of basic utility lines

  • Shell construction of the floors followed by shell inspection

  • Interior plaster
  • Screed
  • Exterior plaster
  • Floor coverings, final installation of electrical wiring, bathrooms, heating
  • Painting work
  • Landscaping, house cleaning
  • Final inspection
Would you say this is roughly correct?

Screed and interior plaster can be done in the other order as well.
Exterior plaster can be applied earlier or later—as it depends. It is independent of the interior work, as long as the house and windows are finished.
Electrical wiring should be installed before the interior plaster (I think you probably mean installations here).
Depending on what you do yourselves, the final inspection will be scheduled accordingly before that trade.
Door frames and doors, in our case, were installed after screed and interior plaster and after the floor covering.

This was referring to the general process of building a house... in our case, this does not apply, since we don’t need a loan.
