Overview

An Australian Architectural Landmark on Mosman Bay

Commanding an extraordinary position above the serene waters of Mosman Bay, 'The Collins House' is a freestanding residence of exceptional architectural provenance and enduring significance. Having previously been recognised by Architecture Foundation Australia as one of the 30 most important Australian houses of the past 60 years, this celebrated home represents a rare intersection of architecture, place and lifestyle. Radical in its conception and remarkably timeless in its execution, the residence unfolds across three beautifully resolved levels, each intrinsically connected to the harbour. Expanses of glass frame sweeping views across Mosman Bay, drawing natural light and the changing colours of the water deep into the interiors. Adding further appeal is the potential to incorporate a lift connecting the home's levels, offering scope to enhance accessibility and future liveability while respecting the integrity of the original architecture (STCA). The principal living level is spectacular in both scale and outlook. An expansive 180-degree open-plan living, dining and kitchen space is defined by the home's iconic windows, creating an immersive connection to its remarkable waterfront setting. A spacious open-plan chef's kitchen brings a refined contemporary edge to the architectural composition, complemented by a butler's pantry offering exceptional preparation space and storage ideal for both everyday living and large-scale entertaining. Crowning the residence is an exceptional rooftop terrace conceived for entertaining. With an integrated kitchen and barbecue, this private sanctuary captures breathtaking panoramas across Mosman Bay an extraordinary setting for long lunches, intimate dinners and evenings beneath the Sydney sky. Three light-filled bedrooms occupy the lower level, including a generous principal retreat with an adjoining sitting room or study. A wraparound balcony, extensive integrated storage and beautifully considered contemporary bathrooms enhance the sense of understated luxury and effortless liveability. A lock-up garage provides valuable flexibility, while the low-maintenance garden surrounds complement the residence beautifully, allowing the architecture, harbour outlook and exceptional setting to take centre stage. - The celebrated Collins House, an Australian residence of architectural significance - Recognised among the 30 most important Australian houses of the past 60 years - Exceptional Mosman Bay position with breathtaking water views throughout - Previously had DA Approval for 2nd car parking - Three expansive levels with stunning water views - Signature 180-degree living, dining and kitchen domain framed by iconic glazing - Magnificent rooftop entertaining terrace with integrated kitchen and barbecue - Three beautifully illuminated bedrooms, including substantial principal retreat with sitting room/study - Wraparound balcony and extensive integrated storage - Contemporary bathrooms and internal laundry - Private, low-maintenance gardens surrounds - A peaceful sanctuary yet a short walk to the Mosman Shops and only 10 minutes to the city Disclaimer: No representation or warranty is given as to the accuracy or completeness of any information prepared or supplied regarding this property, including but not limited to the property description, artist impressions, inclusions, measurements, aspect, views and other particulars.
