Unlike many contemporary mountain estates that rely on sheer scale, Sunny Ridge derives its significance from its relationship with the landscape. The residence appears to emerge naturally from the mountain itself, embracing panoramic ski-resort, valley, and alpine views while maintaining a distinctly private retreat-like atmosphere.

Within the KeyPrice Ultra Elite Collection, Sunny Ridge is classified as an Architectural Landscape Residence — a property where architecture serves the terrain rather than dominates it.

Architecture & Design Philosophy

Architect: Michael Upwall Design
Location: Park City, Utah, USA
Completed: 2004–2006 (public records vary)
Interior Area: Approximately 7,057 sq ft (655 sq m)
Land Holding: Approximately 2.33 acres

Michael Upwall's work is widely associated with what many describe as "Organic Mountain Modernism" — a design language focused on creating homes that feel inseparable from their natural surroundings.

Sunny Ridge demonstrates the foundations of this philosophy:

• Curvilinear architectural forms
• Extensive floor-to-ceiling glazing
• Strong visual connection to mountain vistas
• Natural stone and timber integration
• Sculptural rooflines responding to terrain
• Indoor-outdoor living environments

The residence avoids excessive ornamentation, instead relying on proportion, light, and landscape as primary design elements.

Living Experience

The home was conceived as a private mountain sanctuary rather than a resort-scale compound.

Key Features

• 4–5 bedrooms (public records vary)
• Approximately 4.5–5 bathrooms
• Grand great room with soaring curved glazing
• Multiple fireplaces
• Executive office/study
• Spa facilities
• Expansive terraces and decks
• Three-car garage
• Ski resort, valley and mountain views
• Private ridgeline setting overlooking Park City

The central living space remains the architectural highlight, framed by dramatic curved glass walls that pull the surrounding mountain landscape directly into the interior experience.

Architectural Significance

Michael Upwall has become one of the most influential residential architects in the American Mountain West, particularly throughout Utah's luxury resort markets. His work consistently appears among the region's most celebrated contemporary residences and has helped define the visual identity of modern Park City luxury architecture.

Sunny Ridge is important because it represents an early expression of the ideas that would later define many of Upwall's larger and more internationally recognized projects.

In many respects, Sunny Ridge functions as a design precursor to the firm's later landmark mountain estates.
