OUR VISION
THOUGHTFUL DESIGN, TAILORED LIVING
We’re a small, collaborative team specializing in custom home design. Every project begins with listening - because your home should reflect your lifestyle, values, and vision. From first sketches to final details, we work closely with you to create spaces that feel intuitive, personal, and beautifully livable.
Based in Calgary, Claire Steinmann and Deana Lewis are the DESIGNhaus collaborative duo with a shared passion for designing spaces that are not only aesthetically beautiful but deeply functional. Each brings a unique skill set and creative perspective, and together, they push ideas forward - building on each other’s strengths to craft truly personal and well considered homes.
The DESIGNhaus core philosophy centres around the people who live in the spaces they create. Claire and Deana work closely with clients to understand not just how they live, but who they are - as individuals, as family members, as people with stories, routines, and dreams. They believe great design goes beyond form and function - it’s about choreographing a living experience, and creating a space where life unfolds naturally, comfortably, and beautifully.
OUR TEAM
Creative Partner
Claire Steinmann B.A., M.Arch
I bring a unique and impactful perspective to architecture, drawing on my background in both psychology and design. With a Bachelor’s degree in Psychology and a Master’s in Architecture, I approach each project with a deep understanding of how people live, feel, and connect to space.
My work across residential projects in Western Canada is recognized for its thoughtful detailing and bold solutions. I have a keen eye for balancing form and function in fresh and innovative ways—consistently pushing creative boundaries while staying grounded in the lived experience of my clients.
My approach is further shaped by hands-on experience in construction—from foundational work to detailed finishing and construction management. This firsthand knowledge allows me to design with both creativity and constructibility in mind, bridging the gap between concept and craftsmanship.


Creative Partner
Deana Lewis, B.E.D.S, M.Arch
With a Bachelor’s in Environmental Design and a Master’s in Architecture, I bring a blend of technical mastery and sensory intuition every project. Throughout my career—both leading my independent practice and collaborating with some of Calgary’s premier design firms—I have come to view architecture and interiors not just as structures, but as a single, unified canvas dedicated to the resonance of space.
I look at environmental design through a salutogenic lens, decoding how our sensory receptors subconsciously interact with our surroundings. By intentionally balancing materiality, acoustics, and light, I focus on how a room physically feels, creating tailored environments that quietly soothe or stimulate the human nervous system.
This design approach relies on deep client dialogue and a genuine curiosity about behavioral patterns. Before drawing a single line, my process focuses on uncovering the root of your actual lifestyle needs, translating your subconscious daily habits and psychological requirements into intuitive spatial realities.
