Single-family house from 1950 with backlog of renovations "Charm of the 50s" - renovation costs

Is the energy consultant free in the first consultation?

You have to ask the energy consultant. But in the end it doesn’t matter, you need him anyway and you will also receive funding for him.

Interest rates KfW:

Repayment grants KfW:

Funding options grant BAFA for building envelope:

Funding BAFA for heating:

Clean, thank you! ..... that helps

So the old building won't become an Effizienzhaus 40EE :) Is anything possible with the old building, are there still Effizienzhaus 55 etc? Is that also funded like that?
Is the energy consultant free for the initial consultation?

Thanks!!

Check if there are still funds available. KFW was already quite empty, but individual measures are definitely still possible. Otherwise, the government is planning new KFW funding for renovation.

The initial consultation with the energy consultant was free for us. We are renovating according to KFW 70ee.

When will there finally be pictures and a cost breakdown of the project?

When will there finally be pictures and a cost breakdown of the project?

towards the weekend, then we will go through it with the expert

Another update:
The second appointment with the expert / architect (an acquaintance of ours / retired civil servant) was unfortunately not very enlightening, or rather, he was only able to give us a few more minor details. This might be because (we have the feeling) the expert personally finds the property too expensive and was very pessimistic. I usually prefer someone who is conservative and doesn’t sugarcoat things, but this was noticeable here. He wanted to encourage us more to build new outside.
Example: He advised against KFW because it is too complex, yet insulating the entire house would cost about 40TE (excluding the attic)... Heat pump and solar currently not available (waiting time around 6 months and costs about 80TE)
Here is a brief summary from him:
Insulation of the exterior facade
Insulation of the attic (but not attic conversion, as it is too complex / expensive) – so give up on that area here – the roof is still good, possibly have small gaps repaired by a roofer
New electrical system
Partly remove floors, have them refinished
2 new bathrooms
2 wall cutouts (beams)
Windows functional but to be replaced as part of insulation
Move some heaters forward and create niches
Leave heating including pipes as is or heat pump including photovoltaics (apparently not currently available)
Basement insulation
Renew front door
Painting work etc. is clear.

Where are the main cost drivers? Roughly 200TE for renovation according to him, but he wouldn’t do it.

Yesterday, we definitely realized that we need a construction supervisor who has certain companies / people on hand and can advise us accordingly. Someone who can estimate current prices and also assess the current situation.

A question to the group: if insulation costs 40TE, is this measure even "worth it"? I could heat for quite a long time for that...
