Designing Spaces That Heal, Inspire, and Last

Where psychology informs every detail

Every detail of your home shapes how you feel each day

From the light that greets you in the morning to the flow of spaces where your family gathers, design isn’t just aesthetics, it’s the architecture of your life.

Why Some Spaces Breathe Life Into You

I’ve spent my career asking one question: why do some spaces make you feel alive, while others quietly drain you?

Backed by Science & Experience

With a doctorate in architectural psychology from Waseda University and decades leading Bay Area projects, I design homes that blend emotional intelligence with architectural precision.

Beyond Trends,
Built for Life

I don’t design for magazines. I design for how you actually live,  spaces that reduce stress instead of adding to it, homes that adapt as your family grows, and environments that look timeless today and decades from now.

Who I Am

I’m Dr. J — an architect with a Ph.D. in architectural psychology from Waseda University, blending science and design to create homes that enhance well-being. With decades of Bay Area experience, I bring both precision and empathy to every project.
