When you see a gorgeous picture on Pinterest, the building’s structure, shape, room sizes, etc., is the work of an architect or architectural designer. But the materials, furnishings, finishes, crown molding, trim, millwork, colors, textiles, and all the intricate details that give the space its character—that’s the magic of an interior designer.

There are a lot of misconceptions about interior designers—their role, expertise, and even the value they bring to a project. Many people think their job is purely about aesthetics: choosing colors, picking furniture, and making things "look pretty." While that’s part of the equation, it’s far from the full story.

So, What is an Interior Designer?

An interior designer is a trained professional who specializes in creating functional, and visually appealing spaces. They don’t just focus on how a space looks—they think critically about how it works. They balance technical considerations like space planning, lighting, and materials with your personal style and needs, ensuring that every detail serves a purpose.

The Scope of Their Work

Interior designers wear many hats throughout the process. Their responsibilities can include:

• Space Planning: Arranging furniture and features to maximize flow and functionality.

• Material Selection: Choosing finishes like flooring, countertops, paint, and textiles based on durability, aesthetics, and budget.

• Lighting Design: Layering light through natural, ambient, and task lighting to create the desired mood and function.

• Custom Designs: Creating bespoke elements like cabinetry, built-ins, or furniture tailored to your space.

• Collaboration: Working alongside architects, contractors, and other professionals to ensure the design integrates seamlessly into the build.

• Budget Management: Sourcing products and finishes within your financial limits, often finding cost-effective options that you might not know about.

Interior Designer vs. Interior Decorator

Just like an architect or an architectural designer, interior designers may or may not have some formal education and credentials. Whether they do or not does not make them a good or bad interior designer. However, an interior designer will know how to produce detailed drawings and plans. A decorator will not. A decorator will only specialize in surface aesthetics—things like furniture, colours, and accessories.

Why Hire an Interior Designer?

Imagine walking into an empty home with zero personality. The floors are cold, the walls are stark white and and a bare-bones kitchen with basic cabinets and appliances. 

I’m not just describing a builder-grade or flipped home.

This is a home without hiring an interior designer. Everything you touch and see on a daily basis, everything you enjoy and makes your life easier— that is an interior designer. 

They create spaces that not only look good but also work well for you. Whether you’re dreaming of a kitchen that simplifies cooking or a living room where your family can truly relax, their job is to make your vision come to life in the most functional, beautiful way possible.

Their expertise helps you achieve a polished, cohesive look that reflects your unique style. By understanding what an interior designer truly does, you can better appreciate their role and how they can elevate your home project from start to finish.
