Sarah Pfeffer has been preparing for Castelletto Homes for nearly 20 years. As the founder and director of design, she leads this Charlotte home builder firm with a distinct vision. She creates homes that are not merely on-trend, but “romantic.” Her style blends details from different eras to evoke wonder, warmth, and nostalgia.
While Castelletto Homes opened its doors in 2024, Pfeffer is far from new to the industry. Her career spans two decades. During that time, she spent several years in commercial architecture, executing project designs across 17 states and three countries. This served as a foundational period that now informs her high-end residential work. Pfeffer views kitchens and entertaining spaces through a hospitality lens—akin to a fine restaurant—and treats primary baths with the detailed luxury of a spa.

Design Beyond
This depth of experience allows Castelletto Homes to offer something unique in the Charlotte market: called the “Design Beyond” service. A standout feature of the firm’s process, this involves creating elaborate 3D rendering packages of the client’s entire home and its surroundings. Beyond the floor plans and elevations, it includes interiors to outdoor living and amenities. This comprehensive approach to home design ensures clients feel guided and confident, seeing every facet of their future home before construction begins.
Castelletto collaborates closely not only with homeowners but also with top builders and developers who share a passion for striking design and character-rich projects. “We feel so fortunate to be in this community. We get to design for clients and builders that are equally excited to bring these unique and romantic homes to reality,” says Pfeffer.
Ultimately, the homes are full of magic moments, whether that be a hidden passageway to a secret kid’s fort or a statement speakeasy that transports you to another time.

A Family Affair for This Charlotte Home Builder
Of course, this passion in design is deeply rooted. Pfeffer’s father and grandfather operated a design-build company for two decades. In fact, there is VHS footage of her at age four, walking construction sites with a notepad in hand. Today, that childhood spark has matured into a sophisticated design philosophy. For Pfeffer, it is about balancing the deep love of family. Also it’s about creating magic moments for her children with a passion for creating sanctuaries that enrich daily life.
Castelletto’s clients are not only drawn to a timeless aesthetic but also a home that feels authentic and meaningful. When a truly collaborative relationship forms between client and firm, the result is something special and deeply personal. And the end product is design that enriches daily life and transform homes into true sanctuaries.
