You need an architect when your project changes the structure of a building, and a designer when you're updating how a space looks and functions without touching anything load-bearing. That single distinction answers the question for most Miami homeowners.

The two roles overlap in people's minds, but they're legally and practically different in Florida. Here's how to know which one your project actually calls for.

What an Architect Does

An architect is a licensed professional trained to design buildings and the spaces around them. In Florida, that license carries real legal weight.

  • They design structural elements like walls, foundations, rooflines, and additions.

  • They stamp and seal construction drawings, which is what your city needs to issue a permit.

  • They handle permitting and can manage the construction process from start to finish.

  • They coordinate with engineers and contractors to keep your project code compliant.

In short, if your project involves the bones of the building, you need an architect.


What a Designer Does

A designer focuses on how a space looks, feels, and functions, working within the existing structure. Their work is about aesthetics and flow, not load-bearing changes.

  • They handle layouts, finishes, furnishings, lighting plans, and material selections.

  • They reconfigure interior spaces as long as nothing structural changes.

  • They bring your style to life and make a space feel cohesive.

What a designer legally cannot do in Florida is design structural elements or sign off on structural, mechanical, or life-safety permits. That line matters.

How to Tell Which One You Need

The fastest way to decide is to look at what your project touches. Use these quick checks.

You need an architect if you're:

  • Building a new home from the ground up

  • Adding square footage or a second story

  • Removing or moving load-bearing walls

  • Changing the rooflines, windows, or exterior footprint

A designer is enough if you're:

  • Refreshing finishes, paint, flooring, or cabinetry

  • Furnishing and styling rooms

  • Updating lighting or fixtures without structural work

  • Reconfiguring a space without touching anything load-bearing

When in doubt, if your project changes the structure, start with an architect. They can always bring a designer into the process, but a designer can't legally take on structural work.


Can You Use Both?

Yes, and on bigger Miami projects you often should. The two roles complement each other when the scope is large enough.

  • The architect handles structure, permits, and code compliance.

  • The designer shapes the interior experience, finishes, and feel.

  • Together they cover both the function and the beauty of your home.

A full service Miami architecture firm can often handle both sides under one roof, which keeps your project coordinated and saves you from juggling separate teams.

The Bottom Line

Choose an architect when your project is structural and needs permits, and a designer when you're refining an existing space. Getting this right from the start saves you time, money, and a lot of avoidable headaches.
