House too big, what to do with the extra rooms?

Now I'm curious, how did you solve that then ?

We are still working on it. But it will rather be a division into "my room" and "his room," each with a bed, since my husband snores and I no longer want to sleep on the sofa :D
Then there is a fitness room, one for the computers, and a small TV room with a game console, but only a three-seater fits in there (11 sqm), so it’s not suitable for groups of visitors. Everything is more or less divided according to activities, whereby secondary activities like watching TV or video streaming, since we don’t have a TV connection, also get less room.
There is no space for a guest room, a dining table for more than 2 people, or a seating area. Since we only get visitors twice a year briefly, namely for birthdays, it wouldn’t be worth it.
The conservatory extension is completely reserved for the animals. The laundry room extension is used as a cellar room.
The old bathrooms and kitchens are combined into pure bathrooms, and the kitchen will get a new room.
Suddenly the space is gone.

Why would anyone want to demolish the outbuilding? That wouldn’t even be possible because the stable is partly built into the house. And preserve it? What do you want to preserve there? It’s a simple stable, solidly built. There’s nothing to preserve.

So I would try to make some money out of the unnecessary space somehow. Renting to students can be interesting since they don’t stay forever, are usually very undemanding, and contribute a bit to the repayment.

I also don’t think having a room for every little thing is good. You don’t need a PC room as a single person, just like a small TV room with a console. A fitness room—well, those who do fitness and are interested already have an eye on the room anyway, and those who aren’t athletes won’t use the room later anyway.
Also, I "hate" it when people live together and yet separate themselves spatially again. If I imagine my girlfriend living with me and both watching TV in separate rooms just because we want to watch different things, that’s nonsense. I prefer being in company.

A buddy of mine is single, bought a house too. I can’t say the square meters exactly right now, but it should be around 150.
What he has to do with the house… It’s not even about maintaining the structure. Garden here, garden there, cleaning is also quite a bit, and much more. The saying is true, there’s always something to do.
Three rooms of the house have been empty for years, all in all I think it’s too much for him alone.
Besides the a lot of work, I also imagine it being a bit overwhelming to live alone in a big house, that’s nonsense.

With 1050m² of land you’re definitely working hard to keep it looking nice.

For example, I have a 95m² apartment where I combined two rooms to have a large living and dining room.
Plus a bathroom and a large bedroom + a small storage room.
It’s ideal as a single and you tend to clean and take care of one big room more than three rooms, even if the square meters are the same.
I am remodeling so that I can later convert it back to three rooms again, keeping the options a bit open ;)

So if you buy the house, I would plan spacious rooms where you spend time. Bedroom, living & dining room, kitchen + storage room.
All better than several small rooms you can’t do anything with.

If the price seems strange to you, you should definitely go through the building including the land with an expert. Normally nothing is given away, and if it has been on the market for a while, that’s usually a bad sign!

: Why should one want to demolish the outbuilding? That wouldn't be possible anyway, because the stable is half built into the house. And preserve it? What do you want to preserve there? It's a simple stable, solidly built. There's nothing to preserve.

You wanted to hear opinions. And even if the buildings are currently in good condition, every building requires maintenance over time to keep it that way. Even if you don't want to see that now, it adds up over the duration. Just look at the roof area compared to a normal single-family house. How does it look energetically when the stable is built into the main building?

Until construction, we lived in an apartment in a building complex owned by the family (residential house + former factory or later restaurant building + sanitary block with an estimated 1500-2000 m² of living and usable space and about 10,000 m² of land). It was a bottomless pit both in terms of maintenance and energy efficiency.

I can only agree with Musketier there. Since you are looking for a large property with outbuildings, I suppose you either want to do "something with animals" or otherwise have large equipment (cars, motorcycles, agricultural machines, etc.). That means to me that you are already expecting to work a lot there. Nevertheless, in the initial euphoria, one quickly forgets the work involved all around. There are two of us and our very low-maintenance property with its 1000m2 is already labor-intensive. In addition, there are almost 200m2 of living space. There is always something to do. I would worry least about the rooms in the house. I would keep a much closer eye on the ongoing costs and work around the house.

Moreover, it really seems very cheap. It may be that you really live in the absolute middle of nowhere, but even there the price per m2 is around 40€. If you then also calculate 3 new bathrooms, the remaining value of the house would otherwise have to be set at almost 0. There are usually reasons for that.

: I know your experiences with students are from before, but as a student I certainly wasn't so undemanding that I would have driven 30 km by car to the university just to fight over a parking space there. What exactly am I supposed to eliminate? The rooms cannot be changed due to historical preservation.

: The house is heated with electricity. Almost every room has underfloor heating, the other rooms have regular radiators. The entire heating system including all radiators/underfloor heating is from 2015. I would then install solar panels on the roof in a few years.
