20 Winthrop Avenue is an exceptional four-bedroom, three-storey architectural residence, offering an impressive 520m of house area, expansive living and entertaining spaces, panoramic views and a level of amenity rarely found in the Bunbury market.
With the top floor sitting at an elevation of approximately 50 metres, the home captures sweeping views stretching from Dalyellup through to Bunbury city and the harbour, culminating in impressive sunsets from its elevated living areas and balconies.
The upper level forms the heart of the home, where soaring curved shadow-line ceilings enhance the sense of space across the generous living, dining and kitchen zones. Extensive glazing draws the outlook inside, while direct balcony access creates an exceptional setting for entertaining or simply taking in the view.
The main bedroom is privately positioned on this level with its own ensuite and robe, while a second bedroom provides added flexibility for family or guests. A laundry and additional outdoor entertaining area complete the level.
The level below provides two further bedrooms and a family bathroom, but its standout feature is an exceptionally large private commercial-style gym. Measuring approximately 10m x 6.4m, this is a serious training space within the privacy of your own home. Its generous proportions also provide outstanding flexibility, with potential to be used as a games room, recreation zone or converted to provide additional bedroom accommodation, subject to relevant approvals.
The ground floor forms the substantial undercroft level and adds another dimension to the home's versatility. Here, the double garage is accompanied by a bank-grade walk-in vault and an impressive bar and entertaining area complete with its own toilet and kitchenette. Whether used for entertaining, hobbies, storage or as a private retreat, this entire level provides functionality rarely found in a residential property.
Outside, the scale continues with an approximately 80m cabana providing another substantial entertaining and lifestyle space. Ideal for large gatherings, relaxed weekends or creating a dedicated outdoor retreat, it further enhances the home's ability to accommodate family and guests on a grand scale.
A double garage is complemented by extensive additional hardstand parking, with capacity for more than 15 vehicles.
For medical and healthcare professionals, the location presents another significant advantage with Bunbury Hospital only approximately two minutes away, providing the opportunity to live remarkably close to work while enjoying the privacy, space and outlook of a substantial architectural home.
Further appointments include full ducted vacuuming throughout, high ceilings, multiple balconies, extensive storage and a flexible floor plan capable of accommodating a range of lifestyles.
