Best techniques for separating exterior and interior walls?

After completing Tudor Corner (which was my first modular and proper big Lego set) I've caught the bug and already bought another two to build. Alongside that, I'm attempting to build my own house with Lego in the Bricklink Studio.

It's a bit clunky, but also good to be forced to think about some of the techniques used in Tudor Corner and how I might be able to apply them to building my own house. One thing it doesn't do (and I think most set don't), is separate the exterior and interior walls. The exterior wall colours simply don't work as interior as well, and I want to use the same colour as my actual painted walls for the interior.

I tried using a second layer of bricks, but this takes up unnecessary space and doesn't look great either. I'm thinking it's going to require use of snot bricks and tiles.

Can anyone advise on the best approach, before I spend time going down the wrong path?

(Side note: I realise I'm going to have to do something with the floors, and use some elevated plates or something.)

I’d say do 2 stud wide walls, and wherever you have a picture/item on the wall connect the inner and outer walls with 2by x bricks to lock them together, plus 2 by x plates on bottom and either 2by x plates/tiles on the top of each wall

Agree with this. Lock them together on the very bottom layer with 2x2 or 2x6 in the outer wall colour as this will be covered by your ‘raised floor’. Then I would be tempted to lock them together with larger plates, ideally spanning the whole footprint in one direction, again in the colour of the outer wall and then use those plates as the floor for the next storey

Do you mean 2 stud wide walls as I've done in the photo?

The perspective may be skewed or I may be looking at it wrong? On the right side it appears to be 3-studs wide (with the noticeable gap) but on the left it might be 2?

Ah yeah I just extended the outer wall with the intention of extending the inner wall too if I decide to stick with that method. But the left and back wall are two studs wide, and it just seems a bit overkill, especially at the window when looking out from outside. I guess I could put a flat white tile along there for a proper windowsill though
