Last Listing description (February 2022)
Tropical Beachside Oasis
If the definition of a great quality of life could be encapsulated in a home, then 20 Allenby may just be the Oxford Dictionary's poster child. Located on the Clontarf flats, this beachside oasis includes all the modern amenities one could desire the gorgeous living spaces and dining options each enhance the tropical surrounds in the most memorable manner.
By way of entertainment the home is enormous in scale and embraces the essence of its harbour setting perfectly. From the lobby, with its double-height ceilings, the home will take your breath away as it reveals glimpses of the private oasis ahead. The architectural staircase will tempt you upstairs but from this point one should proceed forward and brace for a scene that would be just as comfortable in a resort in Noosa, or a luxury Villa in Uluwatu.
The home includes stunning living zones, all of which embrace the family friendly swimming pool, adjoining BBQ alfresco and the resort-styled outdoors. This atmosphere will have you welcoming any opportunity to stay home, and if working from home has become a priority then the dedicated study will provide the ideal home office environment and is roomy and conveniently located in a peaceful corner.
By way of accommodation there is a splendid guest bedroom located downstairs, and upstairs the master bedroom suite is a complete standout and measures an incredible 7 metres x 5.7 metres, includes a stunning ensuite and enjoys the added comfort of a northly aspect and wrap around terrace. This level makes for a perfect family retreat and offers great access to the kids bedrooms across the same floor. The roof space is what childhood memories are made of and hosts the perfect hideaway for a kids rumpus in the loft space and currently has Foxtel setup and reverse-cycle air-conditioning for all year round comfort.
Off street parking in the local area is highly sought after and again 20 Allenby is a winner as it offers parking for up to three cars. By way of storage there are multiple sheds, paddle board racks and even the perfect little wine room for getting away from it all.
If you have had your eyes on the Clontarf flats you will know that quality homes in the area are tightly held and snapped up quickly each time they hit the market, making it is easy to see why the streets of Allenby and Monash Crescent rank among the Northern Beach's most appealing.
