Purchase of single-family house - Water is leaking into the basement

Edit: I think the idea of a 5x6m swimming pool in the basement is pretty cool! If at all possible and financially feasible, I would have it finished and please never fill it in!

And what do you do with it? Far too small for swimming, it's just an oversized bathtub...

For children certainly a huge amount of fun and I can well imagine such a private wellness oasis. It has something of a holiday feeling for me.

But then at most as a whirlpool - Altai is otherwise right: at that size you can’t even do a swim stroke...

Counter-current system...

Financing via crowd-funding here in the forum? Now you’re getting a bit carried away

We have two small children (1 and 3) and might possibly have a third, so that would definitely be great. The house is currently (without renegotiation due to the water damage) priced at 280k purchase price without agent fees, so there would certainly be some room to realize this in the future. It all depends on the surveyor.

I wonder how much something like that costs? The house has a new oil heating system (built in 2015 Buderus) which is located in the room next door, so the floor plan was prepared for the swimming pool. However, I would rather not heat 45m3 of water with oil, so a solar system and heat pump would certainly be added. The wall with the basement windows would also have to go, replaced with sliding doors leading out to the garden. Hmm, all in 40,000 EUR?

But it would have to be saltwater; I don't like chlorine. Is something like that even possible indoors?
