INQUIRE

We specialize in biophilic interiors, a practice rooted in nature to support wellbeing.

We believe interior spaces are a living, breathing extension of who you are. When they work, life feels easier. When they don’t, everything feels harder. We go beyond visuals and design for the experience, how the space supports you, day to day.

With over 15 years of experience in residential and commercial design, we bring structure to the process and meaning to the choices. Our multi-disciplinary approach draws on research-backed design principles to create a space you genuinely want to be in.

Discover

We meet to name the problems, talk through what’s not working, what you want instead, and what success looks like.

Refine

As specifics start coming together, we refine selections, resolve the tricky parts, and make sure the design holds together from every angle.

Clarify

We define priorities, timeline, and design details, then map the plan so decisions stay clean and confident.

Realize

The magic is happening, everything is coming together. We handle ordering, scheduling, coordination, and progress updates, all with a tried and true process so the project keeps moving.

We build the visual and emotional world– translating your style, needs, and routines into a cohesive direction, from layout to finishes to feeling.

Meet Sam, the founder of Lemieux Interiors

I’m Sam Lemieux, founder of Lemieux Interiors, a Portland-based interior design studio.

My clients often know what they like, but lack the time (or desire) to sort through a thousand options, compare every material, and second-guess every choice.

That’s where I come in. I translate ideas into a clear direction, then guide the process from concept to completion with edited selections, practical solutions, and a steady hand on the details.

With over 15 years of experience across interior design, art direction, and visual merchandising, I bring a deep understanding of how to balance aesthetics with functionality.
