A rare architectural treasure, The Castle at Mayfair Lane was masterfully designed by noted architect E.B. Green, whose work helped define the character of many prominent early 20th-century estates. This extraordinary residence was conceived in the spirit of a 17th-century English manor, blending authentic Old World craftsmanship with enduring architectural significance. The exterior showcases hallmark medieval influences, including a grand stone archway, quatrefoil windows, and carved lion motifs-details emblematic of Gothic Revival design. The home's commanding presence evokes the charm of an English village while remaining prominently situated within the city. At the heart of the residence is the dramatic two-story Great Room, distinguished by a monumental stone fireplace, intricate wood paneling, and rare carved Gothic trusses reclaimed from an 17th-century abbey-an exceptional and irreplaceable historic feature. Floor-to-ceiling windows, birdcages crafted and hand-painted in Paris in the 1890s, a musician's loft, and a built-in koi pond further enhance the architectural narrative of this remarkable space. The first floor continues the tradition of formal yet functional design, offering an eat-in kitchen with pantry, formal dining room, family room with fireplace and garden access, and laundry. The second level includes four bedrooms and 2.5 baths, along with the Great Room overlook. A top floor guest suite with full bath provides additional accommodation. Complementing the historic interiors is a private landscaped yard with a saltwater in-ground pool, seamlessly integrating modern amenities with timeless design. Featuring 5 bedrooms, 3 full and 2 half baths, a finished basement, and preserved period architectural elements throughout, this distinguished residence represents a rare opportunity to steward a piece of architectural history.
