Demolish the house - use the basement for the new house?

Hello. Does it make sense to keep a basement when an old house is to be replaced by a new one?

Or is it not worth it in terms of cost, since the new house would then have to be expensively designed by an architect based on the existing basement? And thus a standard house with a new basement would be cheaper. After all, one can certainly keep the hole created by the demolition of the existing basement.

I am not familiar with the usual architect fees and the time required, nor the costs for excavation or concreting of a basement.

Depends

How good is the basement in terms of building structure?

Can you use the basement or is it just a filthy hole?

Does it meet the desired external dimensions of the future house?

Do you want a basement that is probably only accessible from the outside?

Do you have advantages, e.g. boundary construction? I know some who have built over the old basement so they are allowed to build on the boundary again.

So the house of my parents (prefabricated house) was built in 1989/1990 on a basement from the 70s (?). In this case (terraced mid-terrace house. The same procedure was done with the two houses next door) it apparently worked well. There is a normal concrete staircase to the basement under the stairs from the ground floor to the upper floor, the chimney was integrated into the new house, etc. So we were able to use the basement (thanks to the slope location with garden access) normally and the house too ;-)

Hello haydee. Interesting what kinds of things there are. I don't have any boundary development. The basement is more of a dump. So not with nice tiled walls. Just a simple basement. The basement is small, the house is partially basemented. From the outside it can easily be accessible, that would be no problem.

I only want the basement for storing food & other stuff. And: the heating system should be there. The new house should be significantly smaller than the old house. If there is still tool, food, and a heating system upstairs, the house would be half full.

Thank you too, Yosan. My answer overlapped with yours. I don't quite understand. "Thanks to the hillside location." Without the hillside location you could have used the basement just as normally.

Hello. Does it make sense to keep a basement when the old house is to give way to a new one?

I belong to the benevolent-review faction. "More details after the autopsy" – meaning: half a pound more facts, please. Storage room available, house connections available, substance good, deep demolition and rebuilding saved: those would already be big plus points. Crucial question: how well does the current top edge of the basement ceiling fit with the desired level of the new ground floor?

That referred to the garden access from the basement ;-)
