The classic brick exterior of this Georgian mansion in Greenwich, Connecticut is secretly deceiving.

From the outside, the elegant structure—which sits on a 3.5-acre lot—hints at a similarly stately and traditional interior.

A few steps into its grand reception hall, however, immediately unveils quite the contrary.

Among the intriguing custom features of designer-owner Luigi Demasi’s creation are handcrafted hardware, Italian porcelain tile flooring and dramatic lighting. With its silver-and-grey color scheme dotted with a smattering of unusual décor (including intimidating light fixtures and a chrome human skull), the 22-room residence boasts an arguably “cold” and “eerie”—albeit extremely contemporary—inside.

Comprised of seven bedrooms and eight bathrooms, the evocative 18,834-square-foot property located at 547 Lake Avenue comes with seven fireplaces, a heated pool, a library, billiard and exercise rooms, a full bar, a glassed wine cellar, an expansive terrace, a cabana, a 3-stop elevator, parking space for six autos and a tennis court. The stunner’s resplendent master suite overlooks views of the atrium garden, and touts a private luxuriant bath.
