Studio Spotlight: Mojo Stumer Associates

At the intersection of modernist precision and timeless sophistication stands Mojo Stumer Associates, the celebrated architecture and interior design firm behind the Old Westbury Residence. Founded by principal architect Mark Stumer, the studio has spent decades refining a bold, signature approach that marries architectural clarity with expressive interiors.

Mojo Stumer’s design philosophy is rooted in balance—between form and function, luxury and restraint, architecture and art. Their projects often feature clean lines, rich material palettes, and spatial drama: double-height volumes, sculptural staircases, and expansive glazing that invites natural light. Interiors are never an afterthought but a continuation of the architectural language, carefully composed with curated furniture, textures, and custom detailing.

The Old Westbury Residence is a clear embodiment of their ethos—collaborating with interior designer Jessica Licalzi and project manager Mike Doyle, the firm created a home that feels both monumental and intimate. Every space flows into the next with quiet confidence, and every element is intentional.

From private residences to commercial projects, Mojo Stumer Associates continues to shape contemporary American design with vision, depth, and emotional clarity. Their work is not just built—it’s experienced. An architectural voice that speaks with elegance, precision, and enduring relevance.
