HK associates revives mid-century modern home with luminous 'casa luce' extension
HK Associates undertook an extensive renovation of a mid-century modern home in Arizona's Catalina Foothills, originally designed and built by Tucson architect Tom Gist. The project, named Casa Luce, aimed to modernize the 1960s structure while preserving its architectural heritage. The original residence featured earthen walls of burnt adobe and a low-slung roof, characteristic of Gist's style. Despite its historical significance, the home required significant updates to meet contemporary living standards. The redesign prioritized enhancing natural light, removing obstructive elements, updating finishes, and unifying the ceiling design to create a seamless connection between the interior and the desert landscape.
Initially, the home suffered from an introverted layout, particularly a dimly lit and closed-off kitchen that overlooked a floor-to-ceiling picture window with views of the Santa Rita Mountains. The spatial continuity was further disrupted by a low mechanical bulkhead, a sunken indoor terrarium, and a compartmentalized ceiling composed of painted wood beams and textured white plaster. The renovation by HK Associates sought to rectify these issues, transforming the living spaces into a light-filled, open-plan environment.
A pivotal modification involved the removal of four masonry piers that supported the central roof. This structural change allowed for the creation of a floating ceiling, dramatically altering the perception of space in the main living areas and enhancing spatial fluidity. This required advanced engineering, precise carpentry, and careful construction. The material palette chosen for Casa Luce emphasizes natural light and subtle design. Artisanal lime plaster walls and sustainable wood veneer cabinetry were incorporated, creating a minimal yet sophisticated aesthetic that complements the home's original concrete, adobe, and timber elements. These materials were selected to reflect the balance between structure and environment prevalent in the Sonoran Desert.
The bedroom wing also underwent a significant transformation. A previously dark and enclosed corridor was reimagined as a passage guided by light. A frosted glass screen positioned at the entrance to the kitchen diffuses natural light, while the partially exposed roof structure casts dynamic shadows that shift with the sun's movement, creating an interactive play of light and space throughout the home. The outdoor areas were redesigned to extend the interior's visual perception and strengthen the connection to the natural surroundings. An infinity-edge swimming pool was added, visually extending towards the distant Santa Rita Mountains from the south-facing picture window. Adjacent to the pool, long concrete steps emerge from the interior, serving as amphitheater seating for outdoor living and framing the desert landscape.
In summary, the Casa Luce project by HK Associates revitalized a mid-century modern residence by addressing its functional shortcomings while honoring its historical integrity. The renovation focused on opening up the interior, maximizing natural light and views, and integrating the home more deeply with its desert environment through thoughtful material selection and innovative structural modifications. The result is a contemporary dwelling that respects its origins while offering enhanced living spaces and a profound connection to its unique setting.
