About this home

Maplemere is one of Lexington’s truly distinctive properties, with origins dating to the early 19th century. The architectural character, historic barn, and carriage house preserve a tangible connection to Lexington’s agricultural past. Set on 1.7 acres in the coveted Meriam Hill neighborhood and directly abutting 27 acres of conservation land, Maplemere enjoys an extraordinary sense of privacy, permanence, and protected natural beauty. Mature landscaping and expansive grounds create a rare feeling of seclusion while remaining close to the character and community of Lexington. Inside, gracious living spaces are designed for both sophisticated entertaining and comfortable family life, all anchored by a magnificent family room that invites gathering. A large wrap-around porch, partially screened-in, extends the living spaces outdoors, creating beautiful settings for dining, entertaining, and enjoying the landscape throughout the seasons. The main level is thoughtfully designed for modern living, with a private second main bedroom offering the rare convenience of first-floor living. Two dedicated home offices provide elegant spaces for work or study, while a handsome library offers a quiet retreat for reading and conversation. Upstairs, the primary suite offers a particularly special vantage point, overlooking the protected conservation land and opening to a private walk-out balcony. Four additional bedrooms provide generous accommodations for family and guests, complemented by a fitness room. The grounds unfold as a private retreat, with a beautiful swimming pool and pool house at the heart of summer living. The surrounding conservation land provides a peaceful backdrop and protected views, while mature trees and gardens create an atmosphere of timeless beauty. There is a rare sense of continuity at Maplemere. The land that once supported a historic Lexington farm now provides the backdrop for an extraordinary modern lifestyle. A landmark property, Maplemere offers something increasingly difficult to find: enduring land, exceptional privacy, and a home thoughtfully designed for generations of living. Ideally situated just blocks from Lexington Center, this location offers exceptional proximity to top-rated schools and major commuter routes.
