Lemieux Interiors is an interior design studio based in Portland, Oregon.

We design for people who want their space to reflect the life they’ve worked so hard to build.

We specialize in biophilic interiors, an approach rooted in nature to support wellbeing. Our multi-disciplinary practice draws on research-backed design principles to create spaces that restore a sense of peace, connection, and belonging to everyday life.

We design for the home and workplace; for people with full-lives and discerning standards.

Most of our clients find us during a season of expansion.

Maybe your business has outgrown its walls, or you're welcoming new people onto your team.

Maybe your family is growing.

Or maybe you can simply feel that the space no longer reflects who you've become or what you hold dear.

You care about craftsmanship you can feel, about sourcing done ethically, about living your values all the way down to the chair you pull up to the table.

YOU are exactly who we’re meant to help.

Who we serve

Using your story, we’ll work as your guide to bring your dream home to life. Ultimately, the aim is for your home to feel warmer, calmer, more like a sanctuary - and most importantly connected to the life you’ve built.  

Residential‍ ‍

Workplace‍ ‍

Designing offices, co-working spaces, and commercial environments that balance collaboration with privacy, structure with flexibility, and visual clarity with warmth. For businesses that want people to flourish in their space.

Hospitality

Designing vacation rentals, hotels, restaurants, lounges, and other guest-facing spaces. Our pairing of strong visual identity with discerning design choices keep a space working day after day, and be a place people can’t wait to revisit.

Therapy & Wellness

Designing therapy spaces, wellness studios, and other healing spaces that support presence, privacy, and ease for both practitioners and clients. That means thinking carefully about sensory experience, how the room flows, how light lands, where softness matters, and how each detail helps the space feel settled.
