Hall, stairs and landing advice

[cluefu]

Hello, clueless interior designer here!

We're having our halls, stairs and landing repainted and thinking all white, with one feature wall in denim drift.

Question is, which wall? Radiator wall or window wall? Please help, I'm rubbish with this.

Reason for feature wall is we thought all white might be too much white? But again not sure!

Any ideas welcome, picture attached!

I'd prefer all white, or all in denim drift with white trim

Thanks @bravotango I did consider those options especially as I loved denim drift in our last house but I can't visualise it in this one as much 😪

Maybe the big wall with the windows in? I like the idea OP
