Bedervale homestead was built between 1836 and 1840 by Captain John Coghill as a country cottage for his familly in Braidwood. The house was designed by John Verge, the designer of Camden Park, Menangle and Elizabeth Bay House, Sydney.
Locally cut timber was used to make the black ash columns, cedar interiors and hardwood floors. The bricks were made on the property, and the sandstone and marble were quarried near Marulan from Bundanoon and Drayton respectively.
For over 130 years the house was inhabited by the Coghill / Maddrell family and the contents of the house that accumulated during this time are still in situ. The collection reflects changing tastes and social habits from Victorian through to Edwardian times.
Margaret and Roger Royds bought the property in 1972, and worked tirelessly to preserve a part of Australian heritage, which is now being carried on by their daughter Sonia Horan and her family.
