Interior design for wellbeing.

Our Services

The quality of your environment directly affects the quality of your life.

We create restorative spaces where people flourish, translating science-informed design principles into luxurious, custom environments that support how our clients live, work, and connect with what matters most.

This is interior design for wellbeing.

Custom designs created with a deeper understanding of how your environment affects your overall experience and performance (emotionally, psychologically, and physically).

Both supportive and beautiful.

Whether residential or commercial, our work is rooted in the same guiding truth: when a space is designed with both creative intention and science-backed principles, it can support how you long to live, work, and connect.

What is Science in Design?

It’s where design intuition meets science-informed care.

Research in neuroaesthetics, environmental psychology, and biophilic design continues to show that the built environment can influence stress, mood, focus, restoration, and overall wellbeing. Because most people spend much of their lives indoors, these design decisions matter in deeply personal, daily ways.

Through her Science in Design Certification, founder Deanna Girardot brings this research into practice, integrating principles of neuroaesthetics, biophilic design, color, light, sensory experience, and human-centered design into spaces that support beauty, wellbeing, and the way people long to live and work.

The program is an intensive certification above typical design education and offers IDCEC-approved credits; only 200 designers across the US can claim certification in this prestigious, emerging specialization.

For Tranquil Interiors clients, that means design decisions are never based on trends alone. Instead, they are guided by aesthetic expertise, deep listening, and a more informed understanding of how the environment can help people feel more at ease, more connected, and more supported in everyday life.

Further Expertise

In addition to her Science in Design Certification, Deanna continues to study, speak, and share insights on the relationship between interior design, wellbeing, and the built environment.

Every Tranquil Interiors project begins with clarity.

Before we move into full-service design, we begin with a paid assessment designed to understand what your space truly needs, how it is affecting the people within it, and what kind of support will create the greatest transformation at home or in your workplace.

From there, we can recommend the right scope, investment, and path forward with confidence.
