PRIME NEWPORT OASIS. Hidden in plain sight, this 31,000+ square foot property is one of the largest residential parcels in the desirable Kay/Catherine neighborhood, right off Bellevue Avenue, and a stone's throw to the Cliff Walk, Tennis Hall of Fame, Redwood Library and Newport Harbor. The property consists of 2 buildings - 40 Catherine, a 3-bedroom/2-bath house, and 42 Catherine, a charming 2-story converted barn with 2 one-bedroom apartments. 40 Catherine features a grand living room - once the office of architect George Champlin Mason with wood-burning fireplace and tall Palladian arched windows. A great outdoor deck and wonderful yard offer seamless indoor-outdoor living with room for entertaining al fresco. A private bedroom suite is on its own floor upstairs, while the main floor includes a large open kitchen/dining, separate dining/study, bathroom and the second and third bedrooms. A first floor garage offers an additional 1500+ sf of storage space or potential additional living area. 42 Catherine offers all the charm of an historic barn conversion with potential for family compound, rental income and/or guest accommodation. The first floor is just one step up, spanning over 1300 sf, with a huge great room, Dutch door, charming patio, wood-burning fireplace, open kitchen, laundry, bathroom, and first floor bedroom. The second floor is an additional one-bedroom apartment, rented to a long-term tenant through April 2025. Sublime!
