Exceptionally renovated duplex with double occupancy on the Flats--an outstanding offering for discerning buyers. The upper residence blends a successful contemporary interior with preserved classic details, and unfolds over 2 levels with a den opening onto an expansive, ultra-private west-facing rooftop terrace with irrigation and striking views toward St. Matthias Church. The lower unit, equally renovated in a more classic style, adds rare flexibility for owner-occupants, extended family or income. Garages, parking and a perfect 10 location complete this exceptional Westmount property-a rare combination of cachet, flexibility and lifestyle.
