Is basement construction possible? Is it worthwhile?

Take a look at the topic by goalkeeper...

I'm new here, how do I find it?

Building a terraced house with [GÜ] independently is the topic..

Calculate at least 50k if your semi-detached house neighbors join in. + expansion on top. If not, it has to be offset step by step there and it can become six-figure. 100% financing or not. If it is already tight now, then ditch the basement. It is mostly used just as storage space anyway or you have enough cash left over. The attic is much better suited for that.

Thanks!

The idea will probably be discarded.
