This is what I was going for / inspiration photos…

Lose the gray sofa and replace with 2 nice armchairs in a fabric that works with the rug , maybe a nice navy. A huge piece odf art above that sofa you have lots of space there so really use it .A big rectangular coffee table that serves the sofa and then a nice table between the 2 chairs You need lighting so lampms on endtables and the table between the 2 chairs for sure . Those pics are bit distorted so maybe post a to scale floor plan on graph paer so we see exactly how big the space is . Post the plan here in a comment in jpeg format also the size of the sofa .

When you say that you don’t want anything new in front of the windows - is that why you have been keeping the grey sofa? I think the grey sofa is ok - it is nice, can seat 3 and doesn’t have to match the other sofa. I don’t think you need additional chairs in the room with the two sofas - it would crowd it, imo.

A nesting table set could be functional and flexible for coffee table(s) - and this set has colors that would connect your existing pieces. Just one idea.

Put wallpaper or wood on the ceiling it will make it beautiful,

I love your space! Do you plan to make any updates to the rest of the home? I think your inspiration look will totally work with the leather couch and rug. The grey couch, dining room furniture and chandelier all have a more traditional look to them. What style is in the other spaces in your house? If you want to mix and match, make it intentional or the flow will be disrupted. I think the DR table could coordinate with a different light fixture and different chairs.

I use word docs to put pictures of elements together to see how they work together in terms of color and shape (remove backgrounds from the pictures of individual pieces).

It would also be helpful to know what is on the wall opposite the couch so we know where traffic flows.

I’d put the brown sofa by the windows.
(Is the sofa new?… re dog…)

Then add two chairs where the sofa was…

I love your rug. And love your inspiration!

I do agree that adding in wood on the ceiling. Or even adding wallpaper to the walls will add a lot to the space.

And then we add all the fun stuff. All the nick knacks and poufs,
Wall decor ….

Change out the gray sofa for two lounge chairs.

Add art and accessories.

I love the way your wood floor and cognac sofa warm up the cool walls. And I like your rug colors. Balancing warm and cool colors appeals to me. The two photographs are really conflicting and confused me at first, but I get it now.  So, for tables, with all that beautiful!!!! wood. What do you think of some glass and metal? Or... What wood and stain is your dining room set? Your space is special. I'd hate to have you settle for just anything.

What do you think or a wall sculpture instead of the usual gallery wall?

Yes! We are in the process of replacing the light fixture as we speak!

Still looking for the perfect one…

Dining room table and chairs are new so they’re staying.

I really like your table and chairs. What kind of light fixture are you getting?

The hotel I am staying at has a wall sculpture in the lobby made up of what looks like bicycle wheels. It would be nice if you could find a wall sculpture that has meaning to you.

Not sure. Hoping to find something linear that doesn’t detract from the window

Are you looking for something with a long drop from the ceiling and then a horizontal profile over the table?

I've been thinking about your wall behind your sofa. It needs to be something that looks good from far away and also close up. The far away but makes me want sculptures for simplicity. The shape of the wall is atypical, giving you opportunity for something really special. I wondered if you live in an area where you could commission a sculptural artist. Or if you were up to designing it yourself. There's also modular sculptures like this one.

This comes in different sizes and has colors I see in your home.

Or you could do something yourself with DYI wood scrap wall art, choosing an upward movement from left to right, the way your wall does.

Do you have any theme you want to highlight? Any hobbies?

It's tough when we can't see the whole space. Similar to your inspiration pic, a large ottoman matching or coordinating as a second option your couch leather would create a chaise effect. It could be a coffee table too.

First thing I’d do is move the rug towards the window, so couch and (eventual) large art are centered. Thought you might like this website.

Because of the dining set and the need to tie both spaces together style wise, your inspiration feels too boho and also believe bringing in darker accessories will help connect the spaces. Grey couch is fine and with cushions, it will tie in better. I’d remove hanging plant and add a large plant (on left) and floor lamp on right.

You may have room for two chairs facing window and the seating area would be more intimate and cozy.

There are a ton of decisions and suggest before you start buying items, you’ve been collecting ideas to help achieve the look and a cohesive, balanced space (ie: coffee table is important/suggest something large).

Thanks for all the ideas!

Here’s the other side of the room, which is actually my front hallway. We no longer have the chair in the photo.

@maureen

I love those ideas and that coffee table is lovely 🥰

And here’s a loose floor plan from the house plans that were left us. It’s a weird configuration with the stage:

Your home is really beautiful! I love the wood color and finish with the light walls. You didn't ask, but I'd replace the entry doormat with something the width of the door plus sidelight. I would want to block the dangerous drop-offs with furniture or define them with something to better indicate the safe movement between adjoining spaces. How do you feel about them? I ask because it's important to nail down the seating and supporting tables first.

Painted Peggys has give you wonderful inspiration photos. Would recommend that you take those and replicate as much as you can. She has provided you with a wonderful color scheme and the textures in her photos are awesome.

@KL

We hate the stage but have to live with it for now.
I have replaced the front mat with a runner since this pic was taken.

Yes, re: chandelier…I want something much lower and a better fit style wise.

I kind of want something dramatic but clear, so it doesn’t detract from the windows or view.

You may end up loving the stage. Maybe it's just a matter of learning to deal with it's apparent challenges. Take heart. Still a beautiful space.
