What Does an Interior Designer Actually Do? Inside the Design Process

Here's a question I get more than almost any other:

"So... what exactly do you do?"

It's a fair question. And honestly, it's one I love answering because the answer surprises almost everyone who asks it.

Most people picture interior design as the fun part. The sofa selection. The paint color reveal. The moment the last pillow gets fluffed and someone takes a photo. And yes, that moment is wonderful. But it is the very last thing that happens in a process that is long, layered, and almost entirely invisible to the outside world.

That invisible part is in the design process, where all of the real design work lives.

Today I'm pulling back the curtain on exactly what happens before a single item gets ordered, a single sample gets pulled, or a single contractor gets called. Because if you've ever wondered whether hiring a designer is worth it I have your answer. (Spoiler alert: the answer is yes)

The Conversation No One Expects

The first thing I do when I begin working with a client has nothing to do with design. It has everything to do with listening.

I want to know how you actually live. Not how you want to live, or how you think you should live, but how you actually move through your home on a Tuesday morning. Where do the backpacks land when your kids walk in the door? Which direction does the light come from in the late afternoon, and does it bother you? Do you eat dinner at the table, or does everyone migrate to the kitchen island? Is there a room in your house you avoid because it just never felt right?

These questions matter far more than "what's your style?" because your style is something we can develop together. The thing I can’t do without you? I can’t see how a family uses a space, and it is the foundation of every single decision that comes after.

This first conversation also helps me understand what a project's success actually looks like for you. A finished room that photographs beautifully is one kind of success. A finished room where your whole family genuinely wants to spend time together is another. Those goals are not always the same, and knowing the difference changes everything.

The Site Visit — Seeing What You've Stopped Seeing

Designers see things. It's both a gift and a mild social inconvenience.

When I walk into a home for the first time, I'm taking in about a hundred things at once. The way light moves through the rooms at different times of day. How traffic flows from the front door to the kitchen. Whether the ceiling height is working for the space or fighting it. Where the eye goes (and where it shouldn't). What the room is trying to be, and why it hasn't gotten there yet.

Homeowners often stop seeing their own spaces. It happens to everyone. You live inside four walls long enough and they become invisible—from the awkward corner in the kitchen to the light fixture that was never quite right; the layout that sort of works but always feels slightly off—know something is wrong but you can't name it.

A designer can name it. More importantly, a designer can fix it!

During a site visit I'm also measuring: room dimensions, window placements, ceiling heights, door swings, outlet locations. These measurements become the foundation of every space plan and furniture layout to come. Buying a beautiful sofa that's four inches too wide for the wall is the kind of thing that happens without them. I've seen it. It is not a fun day.

The Research Rabbit Hole (This Part Takes… a While)

Here's the part people really don't see coming: how much time a designer spends researching before anything gets recommended.

I attend furniture markets. I maintain relationships with vendors and workrooms that most homeowners don't have access to. I track lead times, because right now, in 2026 with supply chains still being disrupted, a piece that looks available can have a 16-week wait. I review trade pricing to make sure you're getting the best value for your investment. I research materials and evaluate specifications so you don't have to become an expert in something you never wanted to become an expert in.

I'm also researching your specific home. Historic DC rowhouse? I'm thinking about what the bones of that space call for. New construction in the suburbs? That’s a different set of considerations entirely! Each home has its own logic, and part of my job is learning to speak your home’s language.

This research phase can take weeksor even months. It is not glamorous. It does not make for great Instagram content. But it is the reason projects run smoothly instead of sideways.

The Concept — Where It Finally Gets Fun

This is the stage where all of that listening and looking and researching begins to take shape into something tangible.

I develop a design concept for each project—a cohesive vision that translates what I've learned about you, your home, and your goals into a clear aesthetic and functional direction. This includes a mood board, a color story, a material palette, and a space plan. It's the blueprint for everything that comes next.

And here's what I want you to understand about this stage: it looks deceptively simple. A mood board is just images on a page, right? But those images represent hours of curation, hundreds of options considered and set aside, and a very deliberate point of view about what will actually work, not just what looks beautiful in isolation but what will work in your specific home, with your specific light, for your specific family.

The concept stage is also where I present options and we make decisions together. This is a collaboration, not a prescription. Your input shapes everything. My job is to give you a clear framework to react to because most clients find it much easier to respond to a vision than to conjure one from scratch.

The Plan — Before Anything Gets Ordered

Once the concept is approved, I build out a full project plan: a detailed specification of every item, every finish, every material. Every piece of furniture with its dimensions, lead time, and trade pricing. Every paint color. Every contractor with their scope of work clearly defined.

This document is unsexy and extremely important. It is the thing that keeps a project on track. It is the thing that means when the sofa arrives, we already know exactly where it's going and that it will fit through the front door.

Only after this plan is complete — reviewed, approved, and signed off — does anything get ordered.

The Design Plan is finished. Now the fun begins.

Who am I kidding? Every step in the design process is fun! I share all of this not to make design sound complicated or out of reach, but because I think understanding the process is what makes it feel less intimidating. There is a roadmap. There are clear steps. And you don't have to navigate any of them alone.

The best projects I've worked on started with a client who trusted the process — and who came to realize, somewhere in the middle of it, that the invisible work was exactly what they had been missing.
