Well, timber frame construction, you need to decide if you want it! Why??
It’s basically a matter of preference whether you choose timber stud walls or solid walls, that’s up to you.
Personally, I’m not a fan, but others swear by it.

- Plastic-coated window sills= what is that?
That’s rubbish, and they look something like this, color varies naturally!

- Floor structure: wooden beams with screed topping (11cm (4 inches) insulation)
= unusual for new builds in my opinion... Edit: sorry, it was a prefabricated house what do you mean?
That usually concrete floors are installed otherwise.

- Central gas heating (condensing technology) = old-fashioned heating system, disadvantages?
You depend on gas and the price of it, and no one knows how long the “resource” will last.

- Underfloor heating throughout the entire ground floor = nice, but unfortunately only on the ground floor, probably not possible because of the ceiling structure why?
It seems to me that underfloor heating can’t be installed with wooden beam ceilings.

- Shower bathroom on ground floor, hallway and bathroom upstairs: heat recovery ventilation = What, a mechanical ventilation system with heat recovery? Why not in the whole house? Is that even possible?
Sure, and it actually makes a lot of sense!

- Hot water boiler (750 liters (200 gallons))= 750l??? Do you have such a high demand or a large number of people? No, just two of us, disadvantages?
Huge unnecessary heating demand! For two people, about 200 liters (53 gallons) should be enough, and whether you have to keep 200 or 750 liters constantly at 60°C (140°F) makes a big difference.

I also think many buyers are dazzled by the attractive exterior. What you spend your time in is more like the inside. The exterior of the building looks great, but inside it’s rather standard. You have to decide whether you want to impress the neighbors or enjoy a nice home.

Ok, this doesn’t sound good at all... 🙁

What would the house be worth to you, excluding the land, based only on the information provided here?

I could hardly answer that for myself, as I'm not a fan of this kind of wall construction. I would say €125,000, which is certainly well below market value!

I’m wondering why you are interested?
- Have you been looking for a property for a while?
- Are you hoping for a bargain?
- Did the listing only just catch your attention?

My point exactly,
that thing looks like a showpiece building,
once you’ve seen it, you might want it,
but make sure not to bring along anyone on the viewing who doesn’t understand the subject 😀
otherwise building a house will get expensive 😱
Better find yourself something solid and properly constructed 🙂

I’m the partner 😀 and my other half knows even less, so I’m trying to educate myself 😀

About the house, well, in our town it’s very rare to find a house for sale, so that’s why we’re interested…
and since my other half knows nothing, I’m worried we might be taken advantage of during the house construction…
plus the rent costs are almost as high as the loan payments…

Oops,

it's similar for us. My partner works in structural steel construction and therefore has some knowledge about insulation, floor slabs, etc. in houses, but mainly about construction specifications and contracts.

I’m more familiar with everything related to the creative aspects 😀 and with technology except for heating. My father is a civil engineer, and my partner’s father is an architect. If we ever had to deal with a property like this, we would definitely take both of them along.

I also recommend you bring someone who works in this field or possibly an expert. Make sure to get access to all the documents showing what kind of technical installations, windows, and other components have been used.

We are in a similar situation at the moment; we would like to stay in our town, but there’s nothing really suitable to buy right now. So you find yourself trying to convince yourself about houses and plots that were previously an absolute no-go :o

Otherwise, good luck with the house purchase. One more thing: looking at the pictures of the building, it seems there are no shutters on the upper floor 🙄, is that right? What then? Also, only standard radiators on the upper floor 🙁

I can’t shake the feeling that this house is really a showpiece, and the problems will only start in full force after five years.
