Description

Tucked along prestigious Biltmore Circle in Phoenix, this 2,100-square-foot luxury casita serves as a high-tech office villa and private retreat on the historic first parcel deeded from the Wrigley Mansion estate.

Marking architect Jeff Page’s first Arizona project following his move from New York in 1996, Jeff designed and construction-managed the custom build from the ground up, including a bent-steel, triple-arch canopy on the main estate.

It stands as a milestone in SpaceLineDesign history—the firm’s final project drafted entirely by hand in graphite on textured mylar before evolving into AutoCAD, AI, and VR. Outside, an undulating sandstone path leads past cascading water gardens to reveal a palette of aged copper, warm redwood, and honed black granite framed by sweeping curved stucco wings.

Modern Earth-Contact Desert Office & Subterranean Garage in Scottsdale

This curvaceous, super-insulated "earth-contact" home office and guest house is seamlessly integrated into the Phoenix-area desert xeriscape. Built 30 inches below grade, the modern detached accessory dwelling unit (ADU) offers eye-level views of native wildlife and desert flora directly from your desk.

Key architectural and sustainable design features include:

Earth-Sheltered Passive Cooling: Earthen berms and masonry walls naturally insulate the structure, mitigating the harsh Arizona heat for maximum energy efficiency.
Subterranean 6-Car Garage: A massive underground garage and storage facility sits completely hidden beneath a 14-foot natural earthen hill, providing a visual buffer from the street corner.
Organic Design Connection: A spiral staircase connects the underground garage to a comfortable three-person office, guiding you past curved, ground-level glass windows that look out into the cactus garden.
NAOS Compliant Architecture: Located within the City of Scottsdale, this sensitive desert project strictly adheres to Natural Area Open Space (NAOS) regulations to preserve the local ecosystem.
