Commercial Interior Design Services

Lemieux Interiors is a Portland-based interior design studio specializing in commercial spaces, including offices, therapy environments, restaurants and client-facing workplaces.

We design spaces that support focus, flow, and day-to-day use, so your environment works with you, not against you.

  • Designing spaces from the ground up with a focus on functionality and aesthetic appeal. This includes concept design, space planning, color consultation, and material and finish selection.

  • Transforming living and working spaces with smart, efficient designs that enhance both beauty and practicality. We analyze the layout, traffic flow, and functionality to ensure that every square foot is optimized for comfort and lifestyle needs.

  • With access to a curated selection of high-quality furniture and decor, we assist you in choosing pieces that complement your design concept. Our expertise in furniture placement ensures a cohesive and balanced look.

  • Creating memorable, welcoming environments that ensure guests feel at home while boosting your property’s appeal.

INQUIRE

We specialize in biophilic interiors—a design approach rooted in nature to support well-being, focus, and how people move through a space.

With over 15 years of experience across commercial and residential projects (including offices, therapy spaces, retail, and hospitality) we design environments that don’t just look considered, but work in real life.

In commercial spaces, that often means something simple but important: people stay longer, feel more comfortable, and move through the space more naturally. Whether it’s a workplace that supports focus, or a customer-facing environment that feels inviting without being overwhelming, the goal is the same—spaces that quietly support what they’re meant to do.

We go beyond visuals, designing for the experience of being in the space—how it supports your team, your clients, and your day-to-day operations.

Our Approach

Inquire

That approach carries through every project—bringing clarity to decisions, structure to the process, and a result that works in real life.

 Design Process

From subtle refreshes to a complete transformation, we bring a
client-centered approach to every full-service design project.

01
Discover

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

02
Clarify

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

03
Design

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

04
Refine

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

05
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.

06
Arrive

This is the moment it comes together. Installation and styling are complete, the space is finished, functional, and ready to enjoy.

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.
