Cost planning - core renovation of farmhouse / country house

On the topic of pellets, I am "Team Kachelmann." Wood belongs in the forest and not pressed and burned. The times when pellets were pressed from industrial wood waste are apparently over. Today there is often top-quality Romanian forest in the tank.

Wall heating could definitely be considered if the room height does not allow a buffer for underfloor heating. It has the advantage of being more flood-resistant, if I remember the Ahr valley reports correctly. I would be very concerned that no real expert for the renovation can be found and one would then have to deal with thermal bridges.

In the many super-insulated houses of today, you can't get the warm air out in the evening anymore. In old houses, you can still cool down much better by airing. Here too, I would indeed base the decision for an air conditioner on the house. If I were looking for an old building to live in, I would probably look for a factory hall with very thick brick walls or a courtyard building.

Have you visited the Ökofen headquarters in the Mühlviertel?

Even in insulated houses, you can ventilate very well. Of course, they heat up quickly without shading, and they do not cool down. We have a highly insulated house, as good as possible, and an air conditioner is not on our wish list. Besides, it doesn’t get warm enough. Maybe the outdoor areas in new buildings should not consist only of [Doppelstabzaun] and lawn.

Preliminary: the thread is new to me, I read everything…

I have to bring this back up.

And I looked at this here

How about this: Object No.: 123869632#yI9nQL | Scout-ID: 128836000

(Where the frogs won’t let you sleep ;))

The plot is nice, but otherwise it only serves to be torn down and rebuilt,

This sentence shocked me a bit. And therefore, also with the sentence from the first post in September and the following statements, I am of the opinion that you are not really aware of what “old building” means or what it means to live in a renovated old building.

Afterwards I would like to have again the amenities I am used to here,

An old house will always remain an old building despite complex renovations. Although a more comfortable one, I do not think (with your priorities and requirements) that it will “suffice” for you.

Is something like this feasible? Budget estimate would be about 200-300k for the refurbishment with purchase costs of approximately 200-250k.

That the walls and the indoor climate are “better” in old buildings was mentioned. I would say: different. Because even with dense modern walls, I would call living in our comfort zone much more comfortable than in older houses where the climate “regulates” itself faster. For me, some of your statements regarding renovation or existing old stock do not fit together. When you read that (albeit jokingly) nothing works anymore without air conditioning, then you have to conclude that controlling the temperature in the house is very important to you. But you don’t have that in an old building – expensive renovation plus high-tech have to be installed. And as you have already read: a renovation is virtually more expensive than a new build with a general contractor – you could sink a small weekend house just into the architect’s fees. Regarding prices: there was recently a thread here about a bathroom renovation that was supposed to cost around 39,000. Ultimately, it is not just the renovation but also the comfort and living in a renovated old building that is a compromise. And I cannot recognize that in your listing of your demands. Nevertheless, the new situation naturally reflects new possibilities that you should take advantage of.

Yes, I have to admit that we have absolutely no idea about living in a renovated old building. We previously lived for many years in an unrenovated middle-aged building (around 1990), which was not exactly great, but also not the end of the world.

Currently, I imagine (possibly naively) that I can achieve such a [new building room climate] in an old building if I have it gutted back to the shell, then install controlled residential ventilation, air conditioning, underfloor heating, and a new heating system, as largely listed above.
Is that a misconception?
By the way, the air conditioning is actually fixed. My husband also has a say in this matter, and the only wish he has very concretely is an air conditioner. That was already the case with this house, and will probably remain so with the next one, given how often it has already been used this year.
Even if another house is better located / has a large shade tree or something similar, we are hopeful about averting the climate crisis, but we are also realists – we will most likely exceed 1.5 degrees, and then in the coming 10-20 years, we will face summers different from the ones we know.
