AK (Andrea Keller)

PARTNER - ARCHITECT

Andrea Keller is a licensed architect and builder with 30 years of experience designing structures that work at the intersection of earth, biology, and sacred geometry. Her practice has spanned four continents — luxury residential, wellness centers, boutique hospitality, and equestrian facilities — with every project grounded in a single conviction: that the body responds to space at a biological level, whether or not the designer intended it.

She builds in rammed earth because it is the most honest material available — thermal mass, mineral presence, zero off-gassing, and a tactile density that synthetic construction cannot replicate. MAGIS is the physical expression of a thesis she has held for three decades: that architecture is healing technology, and the nervous system always knows the difference.

Shannon Harris

PARTNER - INTERIOR DESIGNER

Shannon Lee Harris founded Fuse Living after beginning her career developing LEED-certified spec homes, discovering early that environmental psychology was the missing variable in every design conversation. A certified GREENleader through the Sustainable Furnishings Council and Green Associate through the USGBC, she spent 15 years building both the technical foundation — full-scope residential, new construction, development packages — and a framework that no existing design discipline could contain.

That framework became Homeself Neurodesign: the science of how environments shape the nervous system, and what to do about it intentionally. Combining a Neuroscience Coaching certificate, a yoga teaching practice, and deep fluency in built work, Shannon understands that rammed earth, mineral surfaces, and sacred proportion aren't aesthetic choices — they're nervous system interventions.

She doesn't decorate. She decodes.
