I'm not expert, but I did own a house with very little entry footage. How many feet are between front door and first stair?

If you want to translate your terms, please do....

Why not build a squared foundation.... Is there no need for a room, or something in the basement's corner? I thought the top photo was the entry, but idk...

Questions to ask: • What do you want to achieve? • What will this cost?
• Does plan A make sense? • What’s plan B?

Between the front door and the first stair there is 2,8 m, I guess this will be comfortable enough.

This will be a two level apartment , main walls are given, ( When I bought upper level had been in renovated condition but all off a sudden badly leaked from an upper apartment. Once we had to fix that, decided to extend renovation and will do the basement level. Plan A : basement : kitchen with american style living room small office . , bathroom with shower will took place downstairs.

Upper level : small gardrobe room, masterbathroom ) , and a big room ( later divided for living room and bed room, due to its relative large size .

Thanks everybodies comment Highly appreciated all ideas.
