Highfield Ranch
The Highfield Ranch Addition in Park City, Utah transforms an existing single-family home into a cohesive, expanded mountain residence designed for modern living. This residential addition increases the home from approximately 4,300 to over 11,000 square feet, introducing new living, entertainment, and wellness spaces while maintaining a seamless connection to the original structure.
The design focuses on clear circulation, functional planning, and strong indoor-outdoor integration. The main level is organized around open kitchen, dining, and living spaces that support both daily life and large gatherings. The addition also includes a primary suite, guest accommodations, bunk room, gym, wine room, and flexible lower-level entertainment areas.
Careful coordination of structure, materials, and rooflines ensures the addition feels fully integrated rather than appended. The result is a custom luxury home addition that enhances livability, maximizes space, and reflects the surrounding Park City landscape.
