[Dev Request] Interior Design Reworking

Dear Devs of the Housing Department of Design,

Would it be possible to have a reworking of the interior design of houses? What I mean to say is; and I'll use a large for a reference, I'd like to have a long narrow hallway when you first enter the house, like so:

But there are a few ... well.. many problems when trying to create this.
For starters; the partitions cut off the stairs:

And of course the gaps that come with trying to achieve this look not to mention the annoying pillars that are placed throughout the ground floor:

You're always coming out with new exteriors for houses, but what about new Interiors?

It could be a part of the options category like Larges have, except adding one to smalls and mediums as well.

C'mon SE, I'm tired of not being able to let my creative freedom fly with interiors due to every house literally having the same look.

What about an interior design with a spiraling staircase or Mansion interiors with only one Staircase that doesn't branch out?

What all would you like to see as far as an alternative interior design options?
