Welcome to 21 Westmoreland Avenue, a beautifully maintained 2 1/2 storey century home in the heart of Oshawa's sought-after O'Neill neighbourhood. Built in 1925 and nestled on a quiet, tree-lined street just steps from Alexandra Park, this charming home perfectly blends timeless character with thoughtful modern updates. Offering approximately 1,650 sq. ft. plus a versatile third-floor loft, the home features 3 bedrooms, 2 bathrooms, beautiful hardwood floors, original trim and staircase, a classic fireplace, and a renovated kitchen (2015). Major updates include 200-amp electrical service, a high-efficiency heat pump, gas furnace, and an owned hot water tank. Outside, the mature 35' x 113' lot is surrounded by established trees and lush gardens, creating a peaceful and private setting. The rear deck and hot tub offer the perfect space to relax and entertain, while the detached garage, built in 2021 and equipped with its own electrical panel, provides excellent additional storage and workspace. The private driveway accommodates parking for three vehicles. The partially finished basement adds even more functional living space with a separate side entrance, recreation room, workshop and abundant storage. Ideally located close to transit, Oshawa Hospital, Alexandra Park and highly regarded Dr. S.J. Phillips and O'Neill Collegiate school districts, this is a home that offers character, comfort, space and an unbeatable neighbourhood setting.
