Sullivan Building is a custom home builder based in Bucks County, Pennsylvania, creating enduring homes that combine architectural vision, quality craftsmanship, and modern design. Locally rooted and serving the region for more than two decades, the company works with families, architects, designers, and boutique developers to shape homes around each client’s lifestyle and surroundings.

Its services include custom home construction, renovations and additions, and integrated design-build projects managed from concept through construction.

Renovations are designed to add space, light, and comfort while respecting a home’s original character.

The company’s portfolio includes sustainable new homes, contemporary farmhouses, and sensitive restorations of historic properties. Through its collaboration with sister company Cider Press Woodworks, Sullivan Building can also provide handcrafted architectural details and bespoke furnishings. Across its work, the brand emphasizes thoughtful communication, integrity, and homes shaped to feel personal and lasting.
