Property Description
An architectural masterpiece by Jeffrey A. Beer A.I.A., this extraordinary estate is a bold statement in design and innovation. Conceived as both a sanctuary and a showcase, it blends state-of-the-art engineering with artisanal craftsmanship to redefine modern luxury living. From the moment you enter the grand foyer, soaring ceilings and walls of glass create an atmosphere of drama and elegance. Every room showcases uncompromising detail, from a chef's kitchen blending function and artistry to expansive spaces for both intimate and grand gatherings. Exceptional amenities set this residence apart, including a 75-foot custom firing lane, elevator to all levels, and an indoor pool and spa for year-round leisure. A cinematic theater, sprawling recreation rooms and dual outdoor kitchens with patios make this an entertainer's dream. Smart home systems manage lighting, climate, security, audio and automated window treatments with precision to ensure comfort and control at every turn. The private quarters are equally impressive. Four upstairs bedrooms each offer en suite baths to provide a perfect blend of luxury and privacy, while the main level primary suite is an oasis of tranquility, meticulously customized with the finest finishes. Every detail, from materials to proportions, reveals the vision of a master architect. More than a home, this residence is a living work of art that embodies bold design and timeless character, unlike anything else on the market.
