Welcome to two hundred forty-two Lewiston Road, a rare Wallace Frost architectural masterpiece. This French Normandy estate sits on a double lot in Grosse Pointe Farms. Built in nineteen twenty-six and thoughtfully updated since, this residence blends timeless architectural detail with modern living. Frost's signature craftsmanship shines through in the soaring two-story beamed living room with wet bar, fireplace and French doors to a terrace, and access to an additional entertaining room. Exceptional floor plan offers comfortable living and entertaining spaces throughout the three floors. Main floor has an original wood paneled library with fireplace, and classic Pewabic tile accents throughout the home and offers modern tiles in the updated powder room. Recent enhancements include a heated breezeway connecting to a new attached garage, a custom French kitchen with soaring ceilings and banquet dining nook, a new patio for casual entertaining. Additional updates feature a brand new designer powder room, new custom-matched windows in keeping with Frost's original aesthetic, and modern systems such as dual-zone air conditioning, SpacePak central air, and a full Grosse Pointe alarm system with fire and carbon monoxide detection. Upstairs, enjoy a renovated second-floor laundry with servant passage access to all floors, a gas-converted fireplace in the primary suite, and spacious bedrooms with character and charm. Thoughtful conveniences include a mudroom, custom dog run, and abundance of storage over the garage which could all be converted into an additional in-law or guest suite. Outdoors, extensive landscaping creates eight distinct garden and patio areas across the estate-sized double lot enhanced by a smart sprinkler system for ease of care. This is a rare chance to own a true Wallace Frost masterpiece preserved, enhanced, and ready to welcome its next steward.
