-
Mariah approaches each home as a living organism—honoring its history while revealing its most soulful, contemporary self. She blends eras and natural materials with a curator’s intuition, creating warm, quietly luxurious interiors that feel effortless, personal, and perfectly at home in their architecture.
-
From first sketch to final finish, Mariah guides full-scale builds and transformations with an architect’s eye and a craftsperson’s sensitivity. She shapes structures that honor their setting, refining proportion, flow, and detail to create homes with lasting soul.
-
Mariah designs landscapes as extensions of the home—natural, sculptural, and rooted in place. Her outdoor environments blur the line between architecture and nature, weaving local plantings, pathways, and gathering spaces into serene, lived-in gardens.
-
With a finely tuned editorial eye, Mariah stages homes to highlight their best qualities—inviting warmth, character, and shaping moments of connection. Her staged spaces feel curated yet effortless, resonating with buyers on an emotional level and elevating value for the seller.
