Creating homes with character, warmth, and lasting charm.
THROUGH COLLABORATION, CRAFTSMANSHIP, AND THOUGHTFUL DESIGN
ABOUT US
At the heart of Holley Alley is a design philosophy that celebrates the storied layers that give a house that hard to define feeling of home.
Holley Alley is a small interior design studio led by Miggy Mason, who brings over 15 years of residential design experience and a degree in Interior Design from Cornell University. After co-founding Twelve Chairs Interiors in Boston in 2010 and spending a decade in New England, she relocated to Chester County, PA with her husband and two boys, establishing Holley Alley in the historic borough of West Chester.
AT A GLANCE
-
We create homes that feel effortless, approachable, and intentional. Every project balances respect for architectural character—whether honoring what exists or thoughtfully shaping what's to come—with an understanding of how you want to live. Our thoughtful, methodical approach focuses on the purpose and meaning behind every design decision, resulting in interiors that feel collected over time rather than designed all at once.
-
For new builds and major renovations, we collaborate closely with architects and builders from the earliest stages, guiding interior architecture and material selections to create a cohesive vision. For move-in-ready homes, we thoughtfully layer custom furnishings, carefully crafted millwork, and curated art and decor to create interiors that feel both effortless and personal. We work closely with our trusted trade partners—skilled wallpaper hangers, tile installers, painters, and craftspeople—to bring each design to life.
-
Based in West Chester, PA, we design homes throughout Chester County, the Main Line, and greater Philadelphia. Our projects span from Kennett Square to Chestnut Hill and Chester Springs to Wilmington, collaborating with skilled local craftspeople to bring each vision to life. In addition to our local work, we take on select projects further afield.
