4Line Studio designed this detached gym and casita as a private wellness retreat, grounded in natural stone, board-formed concrete, exposed steel, and wood slat ceilings. The program goes well beyond a home gym, with a professional-grade fitness space, recovery lounge, infrared sauna, steam shower, and cold plunge, plus a casita suite for guests or trainers. Expansive glazing and filtered daylight make the whole experience feel less like working out and more like checking into a retreat.

Stone Surf Ranch is an 8,200-SF luxury estate in Paradise Valley where refined craftsmanship meets the effortless spirit of a private surf retreat. Designed to feel both elevated and deeply livable, the home embraces a slower pace through natural materials, warm textures, and expansive indoor-outdoor connections that blur the line between architecture and landscape. A private casita, pickleball and basketball courts, and thoughtfully composed gathering spaces invite both everyday living and easy entertaining. Rooted in its desert setting yet inspired by the carefree ease of coastal living, it is a private retreat designed to feel like an escape you'll never want to leave.

Set within the quiet expanse of Paradise Valley, this contemporary residence is composed as a dialogue between architecture, mountain views, and the surrounding Sonoran Desert. Rusted metal paneling, chosen to weather and soften over time, pairs with refined modern forms and expansive glazing so the home appears to emerge from the landscape rather than impose upon it. Inside, a restrained palette of stone, wood, and metal creates interiors that are warm and understated, while every major space is oriented to capture framed views of the surrounding peaks. Terraced outdoor spaces follow the site's natural contours and native plantings root the home in its setting, resulting in a residence that feels both grounded and quietly expressive.

Nestled at the base of Camelback Mountain in Arcadia, this thoughtfully crafted residence brings refined warmth into dialogue with modern form. A welcoming entry draws you through a series of warm, layered spaces framed by clean architectural lines and considered materials, while expansive openings capture views of the mountain and balance the home's openness with intimate moments of comfort and retreat. Modern in expression yet deeply rooted in its setting, the home was intentionally composed to celebrate the views, elevate daily living, and feel both timeless and distinctly its own.

4Line Studio designed this contemporary residence in the foothills of Camelback Mountain to frame views in every direction, with each space opening to its own perspective of peaks and ridgelines.

The result is a home shaped entirely around light, volume, and view.

Warm materials and restrained detailing tie it all together into an estate that feels both classic and unmistakably modern.

Clean lines and warm natural finishes keep the home feeling calm and livable despite its sculptural presence.

4Line Studio designed this residence on the grounds of The Phoenician resort as a direct response to a tightly constrained site beneath Camelback Mountain. A continuous spine of natural stone runs through the home, organizing circulation and linking arrival, living, and entertaining into one cohesive experience.

4Line Studio's comprehensive remodel expands and reconfigures this existing residence into a fully renewed luxury estate, building on the durability and efficiency of its original insulated concrete form construction.

New landscaping, upgraded materials, and enhanced lighting complete the transformation, giving the home a striking presence from the street.

Inside, vanishing corner windows dissolve the line between living spaces and the courtyard, pool, and entertaining areas beyond. A refined bar and lounge anchor the social side of the home, while a dedicated wellness space offers a quiet counterpoint for fitness and recovery.

4Line Studio designed this French-inspired Arcadia residence around a simple idea: elegant architecture and everyday livability don't have to compete.

The result is a home that feels timeless rather than trend-driven, made for both entertaining and quiet retreat.

Limestone, warm wood, and textured plaster ground the home in its place and will only get better with age under the Arizona sun.

4Line Studio designed this 850-square-foot detached ADU in Arcadia to feel like an original part of the property rather than a later addition.

It's proof that new construction can add modern living space without sacrificing neighborhood character.

At its heart, a two-story children's zone wrapped in glass opens directly to the grove, connecting play, discovery, and family life across generations.
