Floor plan Silverager new single-family house with option to update to a two-family house

Expansion reserve in the upper floor, the successors can implement if needed.

But ypg did not speak of expansion reserve, rather of active use.

Your approach is exactly as we have planned, but with an additional basement. For me, that belongs and offers space for an extra granny flat.

Three rooms are enough for us

So dining room, living room, bedroom. Where will washing, etc. be done then?
