Our Interior Design ProcessWhile each project is unique, our structured, three-phase approach ensures clarity, organization, and a relaxed client experience from start to finish.
-
Understanding your home. Understanding your lifestyle. Establishing the vision.
Every project begins with a Discovery Call and an in-home consultation where we walk your space, identify opportunities, and learn how you truly live.

Discuss your design vision, lifestyle needs, and long-term goals
Identify design opportunities and potential upgrades
Create a clear plan for moving forward
Provide a customized proposal outlining the project scope and design fee
You leave this phase with clarity, what your project requires, how long it will take, and the investment needed to bring it to life.
