    Turning past the sauna, the pool, internally clad with black Sicilian Basaltina, comes into view. The play of light cast across the undulating GRG ceiling above is mirrored in the water below. A skylight at the far end of the pool and tucked-up out of view, illuminates the end wall naturally by day. At night, this is balanced with electric light to reflect light across the space, modeling and accentuating the ceiling's sculptural form.

    The pool's ceiling is halo-lit from its angular perimeter with two concealed indirect sources, which bounce light down the walls and define the structure's peaks and troughs with a distinct line of light. Crisp white 3500K cold cathode sources illuminate the space by day.

    At night color-variable LEDs provide either a warm white glow or selected colors for dramatic ambiance. The perimeter light troughs provide almost all of the space's lighting, while preventing any light to penetrate the sculptural ceiling.

    Color variable LEDs were used to create a warm glow similar to dimmed halogen for a more relaxed and subdued evening environment.

    Color-variable LEDs at the ceiling perimeter were programmed to create a dramatic look with a deep red color then dimmed so that the effect is minimized to a striking zig-zag line of light. This way the ceiling is expressed without overpowering the wash of daylight at the end wall, or the cool white LEDs at the pool edge from streaking light across the water surface.

    A midnight-blue line of light and the pool's ladder handrail are allowed to reflect perfectly in the water below by turning off the pool LED lighting. Daylight from the skylight is reflected back across the angular ceiling above, rendering the surfaces and displaying the ceiling's dynamic sculptural form.

    The pool itself is lit from two sides by banks of narrow-beam cool white LEDs to enhance the tinted water's blue hue. This lighting solution was implemented after a 'raise and lower' pool floor was introduced that covered the existing pool floodlights. The pool was already cast prior to the lighting designer's involvement, so the fittings were installed through the overflow channel.

    Dark interior finishes and moody lighting characterize the sauna and steam room. Illumination is provided by corner recessed vertical slots and partially concealed louvered downlights.

    The gym is illuminated by cold cathode lighting at the perimeter ceiling coffers and low-level halogen floor washers, which provide a bright indirect light for 'high-energy' workouts, or low-level lighting for yoga. The monolithic limestone volumes that house the sauna, steam room, and showers are also used to uplight the ceilings in both the gym and the dressing area.

    The luxuriously deep Jacuzzi is lit with narrow beam fiber optic steplights, which dramatically skim light across the dark stone, creating impact, defining form, and helping the visitor navigate their footing.

 

Otherworldly and ethereal might be the best way to describe this spa, an addition to a European 19th century country estate. The contemporary spa stands in sharp contrast to the traditionally styled existing residence, melding luxurious materials and finishes—fumed-oak and Black Sicilian Basaltina—with light. The project brief called for the creation of “a series of calming, coherent, and relaxing spaces.” The 5,000-square-foot below-grade space, which includes a swimming pool, Jacuzzi, sauna, steam room, and a gymnasium, is just that. By carefully positioning lighting elements, Lighting Design International created a unique environment. The London firm had a leg up thanks to the dynamic ceiling—a series of folded planes fabricated from glass-reinforced gypsum (GRG)—that architects Carmody Groarke designed as a sculptural counterpoint to the smooth surfaces of water.

Although underground, the spa is connected to the outside via a skylight, tucked-up out of view at the far end of the pool. The opening provides a wash of natural light during the day, while at night, electric sources cast light across the pool. The size of the pool, which is approximately 57 feet long by 26 feet wide, enabled the lighting designers to make a significant statement: A gap separates the folded ceiling plane from the side walls, and the slot emits a haze of fluid light from two concealed indirect sources—3500K cold cathode by day and color-changing LEDs by night. The light accentuates the upper portion of the wall while defining the angular edges of the GRG ceiling, all without ever having to directly illuminate the ceiling itself. The atmosphere is further enhanced by the reflection of the ceiling and its edge lighting on the water's surface.

Banks of narrow-beam cool-white LEDs light the edge of the pool, enhancing the blue tint of the water. As the light from the luminaires stretches across the pool perimeter, the effect reminds one of a series of searchlights, aiding the swimmer who is navigating the mysterious liquid terrain. The lighting fittings were installed in the overflow channel because the pool cover had already been installed and the pool itself already had been cast prior to the lighting designer's involvement in the project.

The sensuous atmosphere continues in the sauna and steam room, where dark finishes and lighting pulled back to the corners emphasize the room's edges. Louvered downlights complement the vertical light slots and provide a sense of drama. The gym uses both cold cathode and low-wattage halogen sources, which family members can select depending on workout needs. Finally, fiber optic steplights illuminate the Jacuzzi.

In order to create a sleek and sophisticated appearance, the client requested that the luminaires be “invisible,” so the lighting team developed a series of custom detailing solutions. The result is an architecture where light is visible, but not the source. Suggesting the hint of a line which unfolds into a volume, lighting is deftly used in this project of carefully considered strokes.

Jury Comments
Jim Baney: Not your everyday kind of a project. The lighting designers have really explored the interaction between light, material, and reflection.
Denise Fong: The space has a magical quality about it. It appears simple, but it's very complex.
Randy Sabedra: Simple, yet a very intellectual design.
