NOT TO BE MISSED!
ALL THIS WEEK BY APPOINTMENT ONLY
Set on an impressive block, amidst established tranquil gardens, this

substantial family residence, with its gentle 'English' touch, seems to beckon
those who desire a certain level of grace and elegance.
Commenced in 1937, the home has progressed through many careful and sensitive renovations, to present today what would be considered not only to be an 'Entertainer's Delight', but more so, a fully-functional family abode designed to meet the growing needs of today's modern, young family.
From the moment you step inside, you sense that this home is something quite special.
For a start, there's the modern, traditional 'country-style' family kitchen, with its tree-top views across the valley, the marble bench-tops, all the mod cons and an abundance of food storage and preparation areas. And if you look very carefully,
you will find the impression of a tiny child's footprint in one of the hand-made, sandstock bricks that are a feature of the interior walls!
The accommodation comprises four superb bedrooms and three beautiful
bathrooms, the en suite of the upstairs Master Bedroom featuring a vanity
fascia that has been fashioned from a stunning 1920's dresser.
But it is the conservatory, with its unique rumbled marble floor that once
featured in Vogue Magazine and the wonderful abundance of space and light
and sunshine that together with the adjoining entertaining deck makes this area
fantastic for entertaining friends or to simply relax and put your feet up.
The Formal Lounge flows onto the Conservatory and overlooks the impressive
front gardens and has a cheerful, warming fireplace and natural, polished timber
floors with the adjoining Sitting/TV Room having a slow combustion stove that
warms the heart of the home. On the mezzanine level is found the Parent's
Retreat and Library and is the perfect place to escape to and find 'peace & quietnwhilst enjoying the valley views from the balcony.
With four antique and converted gas lamps, ducted air conditioning, antique
stained glass and lead light windows, an internal staircase of Australian red cedar
complete with timber balustrades that were originally from the old 'Punch Hotelnin Sydney, a rare Edwardian overmantle from Wales, an imprint of a baby's
footprint in a handmade, sandstock brick and even a reproduction 'Monet's
Bridge' over a natural watercourse in the front garden, all contribute to
making this a property portfolio one that would be difficult to replicate.
And all within strolling distance to Killara High School, (with Ravenswood or Pymble
Ladies College close by), together with the Garigal National Park, Bushranger
Reserve and the popular W.A. Bert Oldfield Oval and Two Creeks Walking
Track just up the road. Gordon and Killara Stations are but a brisk walk away.
This immaculately presented family residence we are sure will be one of the
loveliest homes you are ever likely to find. It's simply 'picture perfect!n* A substantial, residential cottage with an 'English' touch
