Description

Beneath a canopy of century-old oaks, 418 Castania redefines design-led living in Coral Gables. Conceived from the ground up by The Art of Design Development, architecture, construction, and interiors were envisioned as one cohesive narrative. Set on a 10,000 SF lot, this 4,150 SF under AC residence (5,360 total SF) offers 4 bedrooms plus den and 5.5 baths across two levels. Expansive impact glass frames mature front and rear oaks, filling the home with natural light and creating a seamless indoor-outdoor connection. Interiors feature European oak flooring, marble bathrooms, bespoke millwork, custom vanities, European doors, a floating solid-wood staircase, and imported brick accents. The kitchen includes Molteni & Dada cabinetry, La Cornue range, Gaggenau oven, Sub-Zero refrigeration, and Watermark fixtures, while a dedicated bar features Studio Ore brass fixtures. 11-foot ceilings, Legrand switches, a universal Tesla charger, and an air-conditioned 2-car garage complete the interior. Outdoors, an Ocean Reef shell-stone terrace and pool deck, Bonfire summer kitchen, fireplace, covered terraces, pool, and lawn create a private setting for entertaining. Minutes from Coconut Grove, top schools, dining, and cultural destinations.
