Mahratta, Wahroonga, Art Deco mansion in Wahroonga, Australia.

Mahratta is an Art Deco mansion in Wahroonga situated on Pacific Highway, distinguished by curved architectural elements and circular motifs throughout its design. The interior features a grand staircase that stands as a focal point of the residence's architectural composition.

The land originated from a 260-hectare grant to Thomas Hyndes in 1838 and gradually transitioned from timber production into a private residence. This shift marked the broader change of the region from resource extraction to suburban living.

The name reflects the owner's personal connection to Indian history and his family heritage. This choice of nomenclature carries meaning tied to his grandfather's legacy in colonial Australia.

The property is owned and used by the School of Practical Philosophy as its community group headquarters. The house stands at 1526 Pacific Highway, Wahroonga, on a 1.6-hectare garden. The curving red gravel driveway leads to the porte-cochère; the walled courtyard at the back opens through a moon gate to lawns shaded by two Himalayan cedars.

The two dawn redwoods (Metasequoia glyptostroboides) and two red Japanese maples framing the porte-cochère were planted under Sorensen's supervision after 1941, when T. A. Field had him return to extend the 1925 garden. The curving red gravel driveway dates from this phase.
