Three marbles. Three moods.

From the deep richness of Rosso Levanto, to the dramatic movement of Verde Alpi, to the quiet softness of Carrara, each material brings its own point of view to the space around it.

The right surface does more than finish a room. It shapes the feeling of it.

Every detail inside the 2026 Southeastern Designer Showhouse was thoughtfully considered.
 
Set within a beautifully layered European transitional home, each space reflects the power of intentional design, where architectural details, furnishings, and material selections work together in perfect harmony.
 
We’re proud that UMI surfaces were selected throughout several rooms, helping lay the foundation for interiors that feel both timeless and deeply personal. From subtle textures to harmonious compositions, each natural stone surface brings depth, character, and a sense of permanence to the design.
 
A reminder that great spaces begin with great materials.
