Guesthouse is an award-winning residential and commercial Interior Design firm in the heart of South Lake Union in Seattle, WA.  Since 2009, Guesthouse has been transforming spaces into highly personalized interior landscapes.  Sourcing extraordinary materials from around the world and teaming up with local artisans and craftsman, Guesthouse designs are recognized as atmospheric, artful, and refined. Signature notes include daring use of color, unexpected scale, sculptural form, rare vintage pieces, and masterful layering of texture, pattern and light.


Bringing a fresh eye to each project and connecting with clients to clarify intention, Guesthouse creates distinct, authentic narratives that resonate with creativity and sophistication.  The thoughtful and adventurous design process evokes lasting client experiences, driving the conversation forward about art and meaning in experiential interior design.


Commanding continued attention from a referral-based clientele for exceptional residential projects, Guesthouse expanded their portfolio in 2013 to include commercial and hospitality design.  They soon won a large corporate project that earned Guesthouse the award for “Best Commercial Project in Washington State” by ASID, establishing the firm’s capabilities in the field of commercial design.  Guesthouse has been highlighted on HGTV as well as in local design publications including Luxe Magazine, Seattle Met Magazine, and Seattle Magazine who named Guesthouse the “Best Housewares Shop in Seattle” in 2012.
