To begin with, I"d need to know what you want to store. If it's small stuff, depending on what's behind that wall beside the staircase (where the urn stands), open that up to a small w/hooks, shelves, hanging bar. Frame it out with similar molding or make it a hidden cabinet. Baseboard doesn't have to be disturbed; start there. Or, given there is an alcove up the staircase, that's possible, but will look more cluttered. Alternative is a lingerie chest at that same location, wood matching risers or floor or painted white.

I had a similar problem in my entry. Very bland. I incorporated cherry paneling on a partial wall and raised the openings of the interior doorways. As you can see from the pictures…although it is not complete, it added instant warmth and drama and is such a statement at this point I would need very little if any entry pieces. I realize your partial wall is a different set up but thought this might be something for you to consider. Your entry is beautiful already!

I would keep the color very light and the same in all areas of the space including the stairtreads (which look to be painted white at this time). The space would then have the illusion of a bigger space without bringing down any walls.
A small table placed where urn sits would give added function to the space. By adding a large mirror on the wall opposite the arched entry, the foyer would again gain some needed "illusion" space.
Good luck.

Mirrors look great in a foyer and help the space look larger. You can add a hanging coat rack for coat storage or maybe you have room for a small standing coat rack or an umbrella stand. Pictures and flowers also add a welcoming touch.

First of all the urn is pretty enough but not doing anything useful. In small spaces that is a waste of space. Even to change it into a umbrella stand is to make use of the space, if you need umrellas where you live, that is.

With little space do hard editing on what you storage there. You only need a few pair of shoes, and a very few coats. Clothes out of season can be stored elsewhere. And hats can be stored high up! Ad some knobs on the wall, and hang out some coathangers, flat against the wall when having guests.

The corner where the urn is a wonderful area. You can fit plenty there! The only problem with this area is that is is visible from the dining area so clutter don't fit well. Think about what you need to storage there, and have a fitting solution custom made.

A thing to inverstigate: is it possible to expand the area into one of the other rooms? Like making the connection through an other room only. And then bulding closet space in the opening that is no longer needed. What is behind the wall with the picture on it? Can it be made a smal closet there or fitted shelves? Or the wall where the stairs end? Can you have a carpenter build in a hangingspace for coats there?

One of the more clever ways of finding space in a room with stairs, is to make fitted drawers between the steps, or boxes where the step is the lid. But this is not an easy DIY-project.

Solutions that let the items hang flat against the wall is good. Shoe cabinets can be very narrow, making use of space that almost isn't there, and there is clever hanging solutions, for everything, even shoes.

If you rather have the room as a display area you have two (as far as i can see ) very good walls for that. The one with the picture you will se when entering from the street, can be related to the room as a hall, and the wall next to the stairs will be visible from the dining area, so something grand can fit, and still enjoyed from the proper distance, without intruding to much

As an artist I have to ask: Why not make it a tiny art gallery? Fill the area from floor to ceiling with large to miniature original paintings that have a theme- maybe all with a common theme like all having a lime green color component...or distressed frames, similar subject matter or style. Art always speaks, engages and has a sense of presence.

I agree with the suggestion of mirrors! They are magical. I use them everywhere. But rather than framed mirrors how about mirroring the walls themselves. That way they change the architecture by expanding and disappearing. Paintings or photographs could be hung over them by fishing line if just mirror is too much for you.

I would suggest a small vintage piece. Perhaps a small 2 drawer vanity, 1920-1930's, an easy find at a thrift store or antique store. My next suggestion would be 3 frames in black, white mats, and same or companion materials in black and white. Hang them vertically above the vanity. On the vanity I would place a small to medium piece of art glass or pottery, 2-3 books stacked , and a vase for flowers or a danity tall lamp, art deco glass is a thought, for welcoming and warmth and something from nature, a piece of quarts, a seashell or something wooden, I would do the arrangements in soft blues, creamy white, or buttery white. But you could also use some bright jewel tones that would be perfect with your peach color. These items will bring you vistors eyes up your beautiful stairway and also will draw their eyes to the archway, which, by the way, is beautiful but is almost invisible because my eyes went to the floor and then up the stairway and directly to the dining area. I would bring in some bright art, maybe abstract or modern to gently follow the cuve of the stairway. Maybe 2. So there you have my suggestions. Hope maybe they help. Good luck, Pam
