Renovation of old buildings, what awaits us

Hello Jan, I'm bringing this thread back up because I have a few questions for you:

What did you pay for:

- Roofing work
- Electrical installation
- Bathrooms
- Windows

We are taking over a 1930s house in good condition from the family, and the electrician estimates his work (complete new electrical system since 1960, 3 floors of 60sqm each) at around €11,000, he does everything including chasing and installing boxes. If we decide on electric shutters, that will add about €1,500.

Our roof needs partial repairs and new insulation, the roofer (who is also an energy consultant) will come the week after next for measurements. If a costly renovation is necessary, two existing dormers will be removed (new ones are very expensive) and instead Velux windows will be installed. Then we'll make an open attic space there as a second large living room.

Since I don't want to insulate the slate exterior walls (60cm thick), we probably have to take double-glazed windows instead of triple-glazed (that's what I often read?).

Because we are getting the house cheaply, we estimated the renovation costs at €120,000. Much is roughly calculable, except the roof. That could be done for €20,000 or end up costing €60,000; we are curious about the roofer's assessment...

Good luck with the renovation and thanks for tips and suggestions!

11 k€ for 3 floors electrical including old removal, chasing, new installation and materials sounds fair to me. Is the meter cabinet included as well? I estimate the material, depending on the quantity, at 5-8 k€ and the labor is already quite a lot...

It is a cost estimate from the local electrical company, which has carried out work on the house repeatedly over the past years. They know the owner and the house itself.

If setting the chases and sockets would cost an enormous amount, that would be something for self-labor. But I assume that two trainees will do such work and in the end it will cost about 1500€. Then they should do it completely at once.

During the preliminary discussion, it was clearly stated that the distribution boxes will also be replaced, as old screw fuses are still installed and no RCD, etc.

We cannot start before the end of the year anyway, because the tenant still has to move out.

The financing bank naturally wanted some cost estimates in advance to be able to list the renovation costs.
