Post Lane Interiors is a New York–based design studio founded by Siobhan Sudal, who holds a BFA in Communication Design from Parsons School of Design. Her background spans two decades in product and user experience design for global media brands including the Associated Press, Condé Nast, and HuffPost/Yahoo!. Her award winning work in digital design earned industry recognition, shaping experiences used by millions – and grounding her approach in clarity, function, and thoughtful execution.

Today, she brings that same perspective to interiors, creating spaces that are both refined and deeply livable. Drawing from her East Coast roots, her work is grounded in creating spaces that feel balanced, inviting, and designed for real life. Siobhan approaches each project as a true collaboration, guiding clients from initial ideas through completion to create homes that feel personal, enduring, and entirely their own.

Based on the shores of City Island, she lives with her husband, two children, and their lively Aussiedoodle.
