Decorating a Narrow Hallway: Moody Makeover

DIY, Living Area

Published June 25, 2026

We are slowly renovating our entire first floor all at once, which is exactly as chaotic as it sounds. So you can imagine how good it feels to finally have a finished space to show off. Decorating a narrow hallway turned out to be one of my favorite projects in the whole house so far. This little entry hallway went from builder-basic to a moody, classic, European-inspired space that makes me happy every single time I walk by.

Here is everything I did, start to finish.

Starting With the Picture Frame Moulding

The backbone of my narrow hallway decorating is classic picture frame moulding, and I am running it continuously throughout the entire first floor. I wanted that cohesive, custom, old-house feeling where the trim just flows from room to room like it has always been there.

I did the very first wall myself in our living room, and I walked through that entire process step by step if you want to see how it is done: DIY Box Molding Wall Trim Tutorial (Step-by-Step Guide). After that first wall, I knew exactly the look I was after, so I hired someone to continue the picture frame moulding across the rest of the first floor walls, including this hallway. Some projects are worth doing yourself, and some are worth handing off so the whole house actually gets finished this decade.

The Before, and the Look I Was Going For

Here is where we started with this hallway, next to the inspiration image I created using ChatGPT. I have a full post showing how I use ChatGPT to help me decorate this home: Using ChatGPT for Interior Design Help. It was my first step to envisioning how to decorate this narrow hallway.

I was going for a classic European moody vibe. Think rich, dramatic walls, warm gold frames, and a space that feels collected and a little bit old-world, even though our house is very much not a centuries-old manor in the French countryside. A girl can dream. The inspiration image was my kick-off point.

Priming, Then Testing Eight Paint Samples

Once the moulding was installed, I filled all the brad nail holes, caulked the seams, and primed everything so I was working from a clean, even surface.

Then came the part I refused to rush. I painted eight different samples directly on the wall because I wanted to be absolutely sure about the color before committing. Moody colors are tricky. They shift dramatically depending on the light and the time of day, and the last thing I wanted was to paint this whole hallway and realize the color wasn’t quite right.

The Winning Color: Sherwin-Williams Taiga

After living with all eight swatches for a few days, the winner was Sherwin-Williams Taiga (SW 9654). This was my first time using this color. According to Sherwin-Williams, it’s a gorgeous, moody green-gray. Lighting will make a big difference in how this color looks in your home. It was perfect for the dramatic, classic feeling I wanted.

I painted all of the trim and the entire lower half of the wall in Taiga, so the moulding and the wainscoting read as one cohesive, color-drenched bottom half.

For the top half of the wall, I went with Sherwin-Williams Accessible Beige. It’s the perfect warm neutral backdrop, and my most used paint color from all my homes. I knew it would let the mismatched gallery wall I had planned really stand out without competing with it.

Painting the Thermostat

Sadly, I have a thermostat smack in the middle of this wall, right where the gallery wall was going to live, and there is absolutely nothing I can do to move it. So I did the next best thing and made it disappear a bit.

I primed it first with a quality bonding primer, so the paint would actually grip the plastic, then I painted it in Accessible Beige to match the wall. I taped off the screen carefully before I started, so I did not mess up the display. Painting doesn’t make the thermostat disappear, but it definitely makes it blend into the wall better. Your eye goes to the art rather than the thermostat. A small trick that made a big difference.

Building the Hallway Gallery Wall

This is the part I was most excited about when it came to decorating this narrow hallway. I wanted a collected, gathered-over-time gallery wall full of mismatched ornate gold frames, the kind of wall that looks like you spent years hunting down treasures at estate sales.

But, I do not have time for thrifting and hunting down a bunch of different frames right now. I’m a busy mom of five little ones, in the middle of a DIY renovation. So I found frames that give that collected, varied, old-world look and bought them all at once. I’m sharing every single one so you can shop the exact look by clicking here.

I laid every frame out on the floor and moved things around until the arrangement felt right. This step is not optional in my book. It is so much easier to rearrange frames on the ground, and have a plan before you start hanging.

Once I was happy with the layout, I hung everything using these picture hanging strips. I am genuinely obsessed with using these for hanging artwork. They make it so simple, and paired with a small level, getting everything straight is a cinch.

The Final Touch to Decorating a Narrow Hallway: The Runner

The last thing to go in was the runner, and it pulled the whole hallway together. Since this is a high-traffic walkway that everyone in this house tromps through all day long, I added non-slip rug pad grippers underneath to keep it from sliding around. Small detail, big difference.

The Hallway Decor Big Reveal

When it was finally finished, I could not wait to show Stuart and the kids. There is something so sweet about watching everyone walk up to the gallery wall and find themselves in the photos. It instantly became a space we all stop and linger in, which is saying something for a hallway.

And here it is, finished. I love it so much. The moody paint color, the warm beige, the gold frames, the runner, the stunning light fixtures, all of it came together exactly the way I pictured it back when I was staring at that inspiration photo.

Frequently Asked Questions: Decorating a Narrow Hallway

What paint colors did you use in the hallway?

The trim and the entire lower half of the wall are Sherwin-Williams Taiga (SW 9654). It’s a moody green-gray that reads deep and smoky in low light. The upper half of the wall is Sherwin-Williams Accessible Beige. It’s the perfect warm neutral that keeps the space from feeling too dark and lets the gold frames stand out.

Where are the gallery wall frames from?

All of the frames are mismatched ornate gold styles I bought to look like a collection gathered over time, without the years of thrifting. I linked every single one so you can shop the exact look. [LINK: shop all the gallery wall frames]

Can you really paint over a thermostat?

Yes, with a little prep. Tape off the screen and sensors carefully. Prime it first so the paint will grip the plastic, then topcoat it with your wall color. It will not make it invisible, but it blends into the wall so your eye goes to the art instead.

Did you install the picture frame moulding yourself?

I installed the very first wall myself in our living room and shared that full tutorial. [LINK: living room picture frame moulding blog post]. For the rest of the first floor, including this hallway, I hired someone to continue the moulding. It would’ve taken me forever to finish by myself.

How do you hang a gallery wall without putting a bunch of holes in the wall?

I use velcro art command strips for most of the frames, paired with a small level to keep everything straight. Lay your whole arrangement out on the floor first so you are not patching regret holes later. Just keep an eye on weight limits and give heavier or glass frames proper support.
