Here is one AI design but I am

not a big fan of the glass

Do you want to separate it physically or just a visual separation? Are you willing to change the furniture?

Are you looking for floor to ceiling separation? Would just a pony wall work? You could do a pony wall with slats above it or just a plain pony wall.

Or you could do something with just a column.

Or something like this.

You could do a half wall with a bookcase on one side.

If you need storage.

Although not perfect here are a couple of ideas for you

Hi Emily .. what you see now is the current owners furniture . we will be changing all that.. we cannot go ceiling to floor the height is 18 feet.. i was thinking some type of half wall or floating wall just to create visual or physical separation so it doesnt seem like you are walking right into the room

Do you have a floor plan, by any chance? And photos from other angles?

Photos can be deceiving. In this one, the foyer looks as wide as (or even wider than) the living room. I also see a cased opening left of the foyer (how wide? leading where?), and I see a dining area as part of the living room space. A floor plan would help us understand the existing architecture and the traffic patterns, which determine how much closure is appropriate, what size openings make sense, and where they should be.

Be careful with AI rendering making it look like you have more room than you really do. The AI fountain wall is silly and wouldn't even fit in the space you have.

Here are some more photos .. this is how the house looks now .. we are renovating it when we move in.. we will not have a living room there but rather use tge entire space for dining room with may e a couple of chairs in front of the window

The smartest thing to do is lo live in the house for a bit then decide if you still need a separation between the small living room area and the large foyer. In the meantime, consider floating your sofa to use as a divider. Put a sofa table behind it and, voila, a separated foyer. Face two armchairs towards the sofa. This is a wonderful layout for a small living room that opens to an entrance. No construction, expense, or hassle. Plus you'll leave that wonderful large window completely unblocked, which will give the room a larger sense of space.

I thought I posted these earlier but not seeing post anymore. These might give you an idea if you were to do a pony walk or a floating wall between entrance this one is the idea that Maureen suggested.

@housegal200…. my thoughts also. We did something similar in our home with no defined entry. (18’w x 10’ or so D ), we have two matching chairs floated, facing into the living room. we also added an area rug to further define the space. Looks great, & as you stated , no expense,construction, etc.

Most people REMOVE the ”pony walls” where I live.

Kat’s second and fourth examples are lovely. The others are things that homeowners generally remove as being ” dated”.

If I were centering a dining table in that space I’d also make sure that you have plenty of room around the table so it’s not tight for seating. I’d leave the space open myself.

If you planing to use it as dining room, i would not add anything there.

set up your house as you want to, live in it for a few months before deciding whether or not you want a division of any kind

Once you live in the space you will no doubt notice you don't have the footage for most of the suggestions thus far. AI really expanced the wall between the door and the corner to the living room. Which will you choose to decrease the foyer or the living area? There's no wall there now because there isn't room for much of anything.

Main dloor plan

@Emily, your post showed up in another thread-the one asking about what color to paint their stucco house. The minute I saw it, I knew you probably meant to post it here.

Thanks for the additional photos and the floor plan. I see a stairwell going down in the photos that doesn't show on the plan; do you know where it is? Maybe here?

And are you keeping the boxy structure above the stairs? I'd like to raise it higher, if possible. (Is it hiding something like ductwork inside?) Then you could do something like this (if you want this much formality):

The dining table would be centered on the opening, which chatgpt didn't do. Then there might be room for a bench under the window, if you wish. You could also add a chandelier.

The height of the box over the stairs would have to match the height of the bit of wall over the columns, be trimmed the same, and have columns beneath flanking the stairs, with one extra making a pair flanking the opening to the dining room (see plan). (This assumes you're leaving the stairwell open on both sides with the box above. If you're adding a wall on one or both sides, trim details would change.)

And it's a small detail, but chatgpt didn't quite match the height of the molding over the columns to the height of the molding over the entry door/window, which I would want done. And I would want the slate(?) in the foyer centered on the door unit, if possible, which would mean replacing some of the slate with hardwood on the left side. (Chatgpt already removed some slate on the right to make room for the columns.) Matching hardwood is difficult.

One more detail: There are electrical items to the right of the door unit, where the columns would need to be. Chatgpt just moved them, but reality might be harder than that.

And all of this assumes a generous budget, obviously!

Lovely mock above........and a perfect use of space.

Noting the blustery cold winter locale of the house? I will never understand the lack of foyer, even an airlock at front entry.

Dining is a very "public " event. Of all the rooms best suited to a plop, you're in! this is the space for dining.

Nobody wants to sit and relax at the front door - it feels exposed to the world , especially in winter. No guest wants a blast of cold air, as another guest enters!

Treat it as a great dining room : ) live in it a bit and then get some architectural help to the site.

at present you could just place a couple of large plants ( real or faux) of different heights at room side of entrance door

What is beyong that stair case? It appears to be another living space. Perhaps a scaled drawing of the entire home would help us? Is it possible to wall in the staircase creating a room of it's own that will become ???? depends what you need/already have/can dream. A pool table comes to mind.

Better rendering:

Thanks Katinparadise. I thought I had posted those. Just in the wrong place. lol

Some easy option with furniture layout.

What I designed, for some reason the furniture sizing wasn’t working.

I do not see a coat closet so some funky design with some coats hooks would be great.Something like this maybe and not block the side light
