Decorating help - adjoining rooms with different styles?

[carmenere]

We're picking out furniture for the two adjoining living rooms in our new house. I don't have a good picture because we haven't painted yet and all our decor is still in boxes, but picture these rooms with white walls and whitewashed fireplace:





When it's finished, the style of the main living room (with the fireplace and bay window) will look something like this:



We were out shopping over the weekend and H fell in love with this midcentury leather couch and matching chair www.macys.com/shop/product/marsilla-88-leather-sofa-created-for-macys?ID=5131971&CategoryID=35419
I think they would look nice in the front room (second picture above with the big window) but is it weird that it's a totally different style than in the other room? Any suggestions on how to make it work? H has deferred to me on all the decor decisions and this couch is the first thing he's been really excited about, so I'd like for it to work.

I think you just need pieces of both styles to kind of tie them together. Similar color pops or complementary textures. That kind of thing. Think smaller stuff like lamps/light fixtures and accent/side tables. I think it lends to an interesting and kind of eclectic look. Our old house was midcentury architecture and midcentury furniture (either vintage or reproduction)—now that I look back at some pictures it feels like maybe too much of a good thing? New house is late 80s colonial architecture and now we’re working on tying midcentury furniture and accents together with the architecture and new, somewhat more traditional furniture style pieces.

We have two adjoining rooms in the new house. We'll have all grey seating in one room and all brown seating in another room. We're going to use some other things to tie the two rooms together (pillow colours, the same lamps/lighting, etc) but we're also happy to have it looking different to differentiate the spaces (one will be more a sitting area and the other a living room/tv room.

I think you can tie them together with colors and textures, but it doesn't have to be anything big...just a few small touches.

We like a 'collected over time' look, so we purposely don't buy matching sets, and instead choose complementary pieces. A similar style, maybe a different color or texture. I feel like it wasn't hard to make ther rooms flow, since the brain picks up on the subtle tie ins, and it doesn't take much.

Also - can't see the first picture for some reason so can't compare the two.
