on which

[Tepari]

Hello.

Can I say as follows:

The ancient foundations which the new house has been built on was made of stone.

Thank you

Yes. But "on which the new house has been built" is better. I would change "foundations" to "foundation".

 

[Rover_KE]

...or 'The ancient foundations...were made of stone'.

I would change "foundations" to "foundation".

Foundations sound fine to me- maybe it's a US/UK difference.

 

[MikeNewYork]

In my experience, a house has only one foundation. It is what the house sits on.

And in BrE, it sits on its foundations.

Another notable difference. :-o
