Cast Concrete, Steel & Glass on Water Mill's Most Coveted Street

A singular architectural achievement on Rose Hill Road, this gated Water Mill estate spans nearly 19,000 square feet of cast concrete and steel construction wrapped entirely in walls of glass — a material vocabulary as rare in the Hamptons as the 65-acre agricultural reserve it overlooks. Ten bedrooms, fifteen bathrooms, a rooftop deck with sweeping bay and ocean views, a tiered home theater, a heated gunite pool and spa, and a sunken Har-Tru tennis court compose a compound that operates at the precise intersection of museum-quality design and resort-level livability. With Mecox Bay at the end of the street and ocean beaches just beyond, 200 Rose Hill Road is not simply a home — it is a complete world unto itself.
