Hello ,
such reports from real completed projects are always very valuable! Thanks for this contribution.
Are these actually all real paid final prices including VAT?
The price you got is of course very good, we paid the land value + 80,000 EUR for our heavily in-need-of-renovation house.
I still consider that very good. Where did you find the offer?
- Screed with underfloor heating 10,000 EUR: Old screed completely removed and new with underfloor heating installed.
Online you can find benchmark prices of 80 €/m² for screed + underfloor heating (without prior removal of the old floor). Normally such benchmark prices are calculated tightly – but nice to see it can also work out.
Heating 10,000 EUR: We initially wanted just a heat pump, but couldn’t quickly find anyone who could install it. So we first had a gas condensing boiler installed by the plumber. The heat pump will come in the next few years.
What – gas condensing boiler first and then additionally a heat pump? OK, I assume you want to use the gas boiler later to cover peaks during very cold weather, but then it would be somewhat oversized. So in the end that will probably be more expensive overall. I understand that this was born out of necessity because you couldn’t find an installer – but then this is not a solid basis for calculation for the questioner. They should calculate directly with the heat pump.
- Sanitary 15,000 EUR: Replace all pipes, guest WC and small bathroom, no luxury.
I would have estimated new lines at 5k EUR. But guest WC + bathroom for 10k EUR? I would have thought that unthinkable in today’s times.
- Windows 25,000 EUR: The old windows had to be removed and we also had a floor-to-ceiling window installed.
- Electrical 12,000 EUR: No KNX or fancy stuff. Just new and more sockets.
Roughly corresponds to my research as well. I got offers for electrical work for a 120 m² single-family house for 16,000 EUR without plastering.
We did the following ourselves:
- Removed floor, wallpaper, etc.
- Closed and plastered shafts again
- Ground concrete slab
Still missing are finishing walls and laying floor.
Here I would see material costs alone of about 10,000 EUR if you do everything yourself.
We did not do the following:
- Roof: Still from the year of construction, but many neighbors still have it and it is supposedly good.
I don’t understand that. There is the renovation obligation on change of ownership according to §47 Building Energy Act. The roof from the year of construction surely does not meet the requirements. How did you bypass this obligation? And if you tackle that once, you do it properly – i.e. with proper rafter insulation and then I would also offer to renew the almost 70-year-old roof covering.
That quickly costs 50,000 EUR.
- External insulation: Not really worth it monetarily. We will move in first and see how comfortable it is.
New windows (probably triple-glazed) but no external insulation? High risk of mold. And at the latest when the heat pump comes, you have to tackle the external insulation. Again: I understand that you didn’t do it *right away* (also considering your emergency gas heating), but that is not recommended for the questioner.
In total, including tile laying, plastering walls, wallpapering, etc., about 100,000 EUR. From that, we will get about 13,000 EUR back from BAFA.
From which program are the 13,000 EUR?
In my opinion, the following works are still missing from your list, which the questioner must consider for their calculation:
- As mentioned above: roof, roof insulation, facade insulation.
- Dormers (common request for this building type)
- Second bathroom new, if applicable
- Kitchen
- Shutters
- Front door + interior doors
- Stairs (refurbish or new)
- Floor plan changes
- If intervention in the statics or external appearance: building permit, architect, structural engineer
- Scaffolding
- Interior or even exterior waterproofing of the basement (basements are often damp with this year of construction. But of course depends on condition and desired use.)
And so you quickly reach 250,000 to 300,000 EUR.
I absolutely agree with you (and the others) that you should think carefully about what you really need. But you have to keep in mind that some things cannot (or hardly) be done while living in the house. Other things make sense if you’re already working on it (e.g. new interior plaster if electrical work is new). And if you do it once, do it properly (keyword rafter insulation, heat pump, etc.) for the intended 40 to 50 years until the next change of ownership.
