Welcome to LUMA 23 - 2164 Boston Post Road, a fully finished, one-of-a-kind masterpiece for the buyer who craves true distinction over cookie-cutter design. Step inside to an effortless blend of modern aesthetic and refined luxury, where every custom finish is executed to perfection. Bold, sleek, and sophisticated, this residence is a dramatic departure from the ordinary, built for both quiet living and high-style entertaining in the heart of Larchmont village. LUMA 23 embodies "the art of living in light" From arrival, the home reveals its defining gesture: a soaring 23-foot entry volume filled with natural light and architectural calm. A floating staircase ascends as both structure and sculpture, setting a tone of openness carried throughout. At the rear, a second 23-foot ceiling frames the transition to the outdoor terrace, blending interior and landscape. Nine-foot ceilings and full-height doors reinforce this vertical rhythm. The main level unfolds around a central open kitchen anchored by a marble-finished quartz island, with living, dining, and office spaces flowing together. Expansive glazing draws light deep into the home throughout the day. The residence offers five bedrooms, four-and-a-half bathrooms, and a dedicated office. Eight balconies, a terrace, and a deck extend living outward, spaces for entertainment, reflection, and connection to the outdoors from nearly every level. Natural light is a central design element throughout, with large-format windows and orchestrated sightlines creating an ever-changing play of light and shadow. A custom Mondrian-inspired stained-glass installation turns sunlight into a living composition of color and movement. The finished lower level adds space for recreation, media, wellness, or storage, and an attached two-car garage completes the home. Every proportion is considered. Every threshold has purpose. This is a home defined not by excess, but by precision, modern and timeless at once, for those who believe architecture should elevate everyday living.
