The classic design is maintained throughout the interior with high patterned ceilings, lead light windows, grand fireplaces and polished wood floors.
  • A classic colour palette featuring whites and creams ensures the interior design remains timeless, but also leaves room for the new owner to inject their own style and taste.
  • The separate self-contained studio or fifth bedroom makes the property ideal for guests or even in-laws living at home. The kitchen with scullery is also bound to be the envy of any budding chef with an island bench and top of the range appliances.
  • Other features include a swimming pool, enormous laundry room, temperature controlled wine cellar, three large storage rooms and triple lock up garage
  • The property is conveniently located close to Rawson Oval and Tennis Courts, the Mosman Shopping Village, Balmoral Beach, Taronga Zoo and Queenwood Private Girl’s school.

The traditional layout presents formal and informal entertaining, with living and dining rooms all exuding style and worldly charm.
  • The rooms are all generously sized with a billiard room, sandstone rumpus room, dual study rooms and separate library room. Four of the bedrooms have their own ensuites and the master also includes a large dressing room.
  • “There a three separate living spaces, which is great if you’ve got kids and teenagers. They can each have their own space,” Mr Ross said.


Federation Queen Anne


A graceful, symmetrical Queen Anne house set in a large garden. The walls are of painted brick, which contrast with the sandstone window bays, entry steps, verandah wall and verandah piers.
  • Classical columns on the piers support the verandah roof. Pairs of columns support the projecting gable over the entrance.
  • The slate roof is of a half-hipped form and has terracotta ridge tiles and finials.

Designed by Spain and Cosh, the house was built in 1905 for merchant and banker George Porter Esq. The land is part of the original Silex Estate.
Now Glasslyn is the Mosman trophy home of Giselle Chadwick, wife of founding partner of Nanuk Asset Management Paul Chadwick.
  • The grand Federation mansion, called Glasslyn, and set on more than 2000 square metres was “soft launched” earlier this week by Savills’ Adam Ross for $16 million to $17.5 million. Its official launch to the broader Sydney market is set for late January.
  • The property last traded a decade ago less than two weeks before Christmas for $11 million.
  • Fuelling interest among expats this year is the low Australian dollar, currently at US74¢, says McGrath’s Michael Coombs.
