ᐅ Timber Frame Construction – Is a 10 cm Exterior Wall Thickness Enough?

In my opinion, you can save at most 50% on energy costs through insulation. That amounts to about 80 euros per month.
In my view, insulation is not cost-effective over the next 20 years.

Then I hope there are only a few heirs involved. The only thing worse than "real estate agents" as a scourge of humanity are "agents and groups of heirs."

Tomorrow is Friday. If you can access the building file then, we can share our input over the weekend. If you can find out the history of the sales efforts, that would be very helpful. How much "competition pressure" are you facing?

I can only ask the agent tomorrow.
He said there are 28 competitors.
The house is on the market for the first time now.

I just calculated your estimate, and after 20 years, that would be just under 20,000 euros.

It’s not just about saving money – if the cold radiation from the walls makes life unpleasant, then you can’t take comfort in the thought that the cost of insulation might not be recovered.

So, in your opinion, I shouldn’t insulate because otherwise I risk mold problems?

No, that doesn’t mean you shouldn’t consider insulation, but you also need to pay attention to ventilation. In some cases, a decentralized ventilation system may be necessary alongside insulation.

Otherwise, 180 kWh/m² for an unrenovated 1980 building is quite normal.

Is a house like this worth it at all if you only have around €60,000 for renovations? (We are inexperienced)

I am skeptical. With that budget, first of all, not many unexpected costs can occur, and secondly, you will have to do a lot of work yourselves. How old are the kitchen and bathroom? What about the electrical system? Which heating system is installed, and is it still functioning properly?

- Kitchen would need renovation (wallpaper & floor)
- Bathroom is already renovated
- Electrical system would need a complete replacement (from 1980)
- Heating system has been renewed, but old pipes remain

No, that means you not only have to include insulation on your list, but also ventilation. You might then need a decentralized ventilation system in addition to insulation.

Otherwise, 180 kWh/m² (18,000 BTU/ft²) for an unrenovated 1980 building is relatively normal for us.

I guess something like that would exceed our budget. 🙁
