Beautiful is just the beginning….
The quality of your environment directly affects the quality of your life.
West Michigan interior design for restorative living and working.
Tranquil Interiors creates restorative spaces where people flourish, translating science-informed design principles into luxurious, custom environments that support how our clients long to live, work, and connect with what matters most.
Our clients thrive in spaces that restore their energy, strengthen their most important relationships, and support their long-term wellbeing. Whether at home or in a small business environment, they are seeking more than beauty.
They want a space that fully supports how they live, work, and feel.
We differentiate ourselves through a science-informed approach to interior design, translating neuroaesthetic and biophilic design principles into spaces that help people live, rest, focus, and connect more fully.
Led by designer and neuroaesthetic practitioner Deanna Girardot, SIDC,Tranquil Interiors bridges the gap between emerging research on how environments affect the human nervous system and the lived experience of everyday life.
Through a deeply collaborative and emotionally intelligent design process, Deanna translates complex ideas about light, materials, nature, and spatial harmony into environments that feel restorative, intuitive, and deeply personal.
Spaces designed to flourish.
Your home or workplace should do more than look beautiful.
It should help you feel calmer, think more clearly, connect more deeply, and move through daily life with greater ease.
At its best, interior design becomes more than a visual experience. It becomes an essential part of how you care for yourself, how you connect with others, and how fully your environment supports your wellbeing.
Not trend-driven, lifestyle driven.
Our work is rooted in authenticity, connection, quality that endures, wellbeing, and stewardship, creating environments that feel deeply personal, thoughtfully crafted, and aligned with the way our clients actually want to live.
We offer more than design services: we create science-informed environments that foster wellbeing, deepen connection, and support the wellbeing of all within them.
For those seeking a deeper design approach.
Very few of our clients come to us asking for “science-informed design”: instead, they are communicating how their home feels out of alignment with the life they desire. Or that although their workplace may be functional, it doesn’t energize, restore, or empower the people within it.
They want beauty, yes, but beauty alone isn’t enough for them.
They want a space that brings more ease to their daily life, supports the life they desire, and fosters a deeper sense of connection to what matters most to them.
"It was not until we built and moved in could we fully appreciate the thoughts behind space flow and function that she had put into the build.
Our only regret is we don’t plan on building again!"
—Colin R | Residential + Commercial Client
While many designers focus primarily on aesthetics, we focus on how a space functions for the people within it: emotionally, psychologically, and physically.
The result is more than just a beautiful new space, it’s a sanctuary designed to support your very best life.
For nearly three decades, Deanna Girardot, SIDC has been creating interiors that do more than look beautiful.
Her work is rooted in the understanding that our environment shapes how we feel, function, rest, and connect.
Long before she had the language of neuroaesthetics and biophilic design, she was already designing with a deeply intuitive and empathetic understanding of how people actually live.
Today, that same perspective guides every project, translating science-informed design principles into restorative, custom spaces that feel as supportive as they are beautiful.
“I value the experience our clients have with Tranquil Interiors, from the very first phone call and well beyond the big reveal.
We aim for a warm, empathetic, deeply connected, and fully supportive process.”
